PSA: Don't download the iOS update for Blockchain.info wallet that was put up today. There's a bug that makes Bitcoin payments more difficult.

(Note: It's my opinion not to download this update, like I did. I wish I didn't.)
Upon updating the app, when you click "Pay With Bitcoin" links that are inside of things like Gyft (which uses BitPay), then it results in the payment amount NOT being brought over into the app. Only the payment address gets brought over. The payment amount stays listed as zero BTC, when in the past the payment amount would get pasted in.
As of now you need to memorize the payment amount exactly or somehow copy and paste it into the Blockchain app.
In my opinion please don't download the update that came out today.
Respectfully,

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I posted this on /cryptotechnology . It attracted quite a bit of upvotes but not many potential contributors. Someone mentioned I should try this sub. I read the rules and it seems to fit within them. Hope this kind of post is alright here...
EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [email protected] . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
A logistic and transportation company
A delivery company
A company that buy and sell real estate options
A company that manage real estate
A software development company
A world-wide fiat money transfer company
A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money exchanges.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [email protected] .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.

4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?

This question is beautifully answered on StackExchange.

Idea | Tip Nano to creators

Hey guys, my name is Tolik and I'm new to Nano.
I would like to tell you a bit about myself, and then about some ideas that I would like to share with you :)
I'm a content creator form Israel, and I have about 65k subscribers over my 3 channels. I'm also the first Israeli partnered on Twitch and been doing that for 8 years now.
Had a lot of fun with it for the first few years, playing my favorite games and earning good money, and eventually burning out hating the game that got me all my following. Our (Israeli) community exploded on youtube, but to make the most of it you need to make mindless trendy content, playing trendy and pretty childish games. I did that for a while, but it was too hard for my mind and I ended up burning out hard stepping away for a long while.
Back in 2013 I first stumbled upon the world of crypto and realized the potential of the blockchain and the implementation of that technology in our world. Not enough to buy enough to get rich, but I never even considered that it could get to the volumes it got to now. In 2017 when it exploded, I realized I had some leftover coins from 2013-14 and cashed out a few thousand dollars, with the pain it could have been millions if I was a little more aware. Oh Well.
A few years ago, I got into the world of self-development and got a new perspective on life. Doing only what I love and grooming a small but good community on youtube, not caring about trends, views, and money in my pocket.
A few days ago, a colleague of mine started to promote some unknown coin to his child viewers, basically, the premise is a coin that you could mine on your phone. Immediately I had some red flags popping off my mind, especially because he promoted some shady CSGO gambling sites that I didn't even want to look into. He of course had his promotion code for registering to the gambling site, and using the mentioned crypto (downloading the app).
If you can mine it on your phone, what would stop you using an expensive setup and just dominate the market? The fact that he advertised it as a get rich scheme, and the fact that it's a referral pyramid network, does not seem safe.
After looking into it I did not see any promise, especially after I found so many altcoins with big communities that his crypto didn't have, information that did not add up, and a bunch of weird stuff going on.
Because I started researching the crypto world (after so many years not being aware of what happened to it), youtube started suggesting me videos about it, one of them was u/SonderDev 's nanoPaint (Sorry I made SpongeBobs eye red) and started doing some research on nano and the technology. For 3 days I devoured all the info I can, reading most of the posts here on reddit, and joining on Discord and TG. I again felt that butterfly feeling in my gut, the one I felt so many years ago when I found out about bitcoin (and some other rare occasions). So much potential, and I kind of feel I am already late to the party, and yet, my mind can't stop thinking about what is possible.
Now to the good stuff! Donations(tips) to streamers and content creators were always a huge part of our revenue. But we had a lot of problems with it - High fees, making small donations pretty much impossible, and the fear of someone charging you back and having you pay the fees for every donation that got charged back. I had someone give me about $2k for the span of two months with small donations, ended up charging all that money back, and having me pay $10 for each of his donations, even if they were under that amount. PayPal is pretty crazy.
Also, If you consider something like Patreon (a monthly donation for a project or a creator you like for benefits) they also charge extra for their fee, and people can still charge you back, even though they will handle it, you still give them the benefits. Twitch takes a huge cut for subscribers (user pays $4.99 and I get as little as $1.70) and youtube are getting about 30% for their cut.
See where I'm going with this? As proof of concept, a simple donation website/app could be made. You send the creator any amount of nano, it pops up on the screen for everyone to see. People would love the idea to impact the stream with as little money the creator allows. That would start up a conversation, people would start seeing the technology in action, how fast and feeless everything is going.
Not to mention an integrated service could be made that is similar to delegate.it (allows users to do tasks for nano/fiat) in this instance, the tasks could be - follow the creator on Twitter, Instagram, like his posts and whatever else he decides, and it could be cheap, because people would be doing it to pop up on stream and help the creator, not for the actual fiat amount of the nano given. killing 3 birds with one stone. Promoting nano, allowing everybody a voice to a degree they choose, and promoting himself to his viewers.
If this works, we could either go to one of the 2 biggest platforms (StreamLabs and StreamElements (who are Israeli and I know the 2 founders personally)) and they would integrate it to their already build system, or develop something to solely promote nano. We could reach out to smaller streamers that have small dedicated communities, not many donations and revenue coming in and allow them to use our system to promote their content and interact with their viewers.
A few more ideas I have in mind for a project like that:
For the donations (tips)
• Having different donation alerts for different QR codes that you scan. Similarly to what NanoPaint accomplishes, we could have a different QR code to scan for an alert that the user chooses to show up.
• Coloring the Camera frame - similarly to NanoPaint, drawing pixels on the frame of the camera of the streamer, changing it in real-time for nano.
• Having text to speech for the alert
• Have your donation impact the streamer in AR (putting something on his face or head).
Crowd Funding
• Donation goal that will make a purchase only if it gets there - setting up an X day goal to buy a new GPU for example, and having people contribute to it, and if it's reached, it automatically makes the order from amazon or wherever (having the data safe with our service), and if it's not - fully refunding the users. It could be a daily goal for pizza or whatever they choose. It will allow integration with businesses that would work with us.
• Stream goals - if we get to X Nano this stream, 24 hour stream tomorrow! If we won't, get your nano back! Would encourage people to participate even if they are not sure the goal will be met, have the assurance that the full amount would be refunded if it did not get there.
• Challenges - starting a bounty challenge, for example, have an Ace in CSGO (kill all 5 enemies) and get X amount of nano. If you didn't, money goes back. the crowd could vote on it having more interaction and validating if the challenge is complete.
Voting
• Have people engage with polls in real-time with nano, could scan their option to vote, and even get refunded if their option did not win, encouraging them to vote for their favorite option, even if it seems unlikely to win.
User Battles
• Having people start a challenge of a game, in an app or on the web, or perhaps even something random like gambling, and having it appear on stream for everybody to witness. Maybe even challenging the streamer for a nano incentive or someone else who watches.
Chat
• Having an on-screen chat that changes the colors and design of the people who donated with nano, and linked their account. more incentive to donate.
Stream Sponsors
• Having a rotating banner on-screen at all times, allowing users to pay nano to show their banner. As an auction or a price set from the creator.
Most of these ideas occurred to me as I was writing this post, and I'm sure we could think of better ones with some effort. Some of them are already implemented on the websites that were mention above, however, having the power and speed of the nano is a game-changer IMHO.
So why am I writing this post? First, just to share with you and get to know you better, maybe spark an idea or a motivation for anyone to do something good for nano.
Second, money is tight now, moved back to my parents due to the pandemic, hard to find a decent job as we have more than %20 of the people in Israel looking for a job and as I mentioned before the content I make is not very profitable. I can't afford to invest money in this idea, and I lack the skills to do it myself. So maybe if it's good someone else could.
If, however, someone would be inclined to help make this a reality, I would appreciate any comments, suggestions, investment of time, or money in testing this out. I have a dedicated community with thousands of people that will be aware of nano if we'll do it, years of experience in this field, and not to mention that I'm in good relations with most of the other content creators and platforms here in Israel, and some international.

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I originally posted this on /cryptocurrency. I just thought you guys might be able to help as well so I posted it as well. I didn't link to the original post because the bot here keeps deleting my post, even if I use the np link. Hope that's ok...

Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.

My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

TIL that Satoshi left scrapes of GUI functionality for poker game in the Bitcoin Core in the 2009

TIL Satoshi left scrapes of poker functionality in the Bitcoin Core in the 2009
Today I stumbled upon a weird functionality in the uibase.cpp file in an old bitcoin node file I was reading for fun, Satoshi had written scrapes of GUI functionality for a poker game in the early version of Bitcoin 0.1.3 and maybe a little earlielater (didn't actually check that deep).
If Satoshi was planing an experiment with op codes for provably fair poker game in the very Bitcoin node (what an exciting thought lol, would actually download the entire blockchain), we may never know as I did not find a lot of info regarding this decision hidden in plain sight. The code applies only to the GUI dialog and is referenced in the uibase.h, uibase.cpp and uiproject.fbp.
As an unnecesary discovery this is, I actually thought this is a pretty neat fact I did not find anywhere else.
Also, as I am making my own private DPOS decentralized network, I think that this is a neat idea I could put in. Although I admit that this idea was almost certainly created long time ago when smart contracts were introduced.

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [[email protected]](mailto:[email protected]) . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
  1. A logistic and transportation company
  2. A delivery company
  3. A company that buy and sell real estate options
  4. A company that manage real estate
  5. A software development company
  6. A world-wide fiat money transfer company
  7. A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [[email protected]](mailto:[email protected]) .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.

4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?

An In-Depth Guide to: How do I Fix my Ledger Nano’s Stuck Ethereum Transaction?!?!?! (It’s Been Stuck for Weeks and NOTHING Traditional has Worked!!!!) As Well as: How Do I Choose My Nonce??? I’ve Tried MetaMask, MEW/MyEtherWallet, and Others, but Nothing is Working Correctly!!! I’m Dying by Stress!

So, if you were like me 1-2 months ago, you’ve probably already gone through 2,or 3, ...or 40 articles and guides that probably say something like:
“YeP, eVeRy EtHeReUm UsEr WiLl EvEnTuAlLy HaVe ThE LoW-gAs ExPeRiEnCe, YoU’rE nOt AlOnE! DoN’t FrEaK OuT tHoUgH; ThErE iS a WaY tO fIx It!”
Chances are, every time you read another useless article, you want to kill the nearest inanimate object, even though it was never alive in the first place. Nonetheless, you’re gonna kill it as much as it can be killed, holding nothing back; or, you’re just plotting to and slowly getting closer to executing the plan (and the object) every time you are insulted once again.
However, if you have the ability to download software (MyCryptoWallet) on a PC, it should be safe to relax now. I think you’ve finally found some good news, because I am 99.99...% sure this will work for the issue that so many people are having at this time, around the end of the month of May, year 2020.
More and more people are likely to be having this issue soon, since Ethereum's gas prices have been insanely high lately as well as having 300% price changes in a matter of minutes; Etherscan’s Gas tracker is nearly uselessly-inaccurate at this time. I've heard that there's a congestion attack; that was said a week ago, and it appears to be ongoing... (I can't think of any other suspect besides Justin Sun to blame it on... it must be incredibly expensive to overload the blockchain for this long... I may be wrong though...)
 
Let’s begin
For myself, I was trying to send an ERC20 token when this dreadful issue attacked. Specifically, the token was either BSOV or GRT; I sent them 1 after the other and the first succeeded, and the second one took over a week.
(They’re both great tokens in my opinion and deserve much more attention than they’ve been getting. BSOV is nearing its 1 year anniversary as I write this, and GRT is still in its 90 day community-development progress test, so of course I'm gonna take this opportunity to "shill" them; they are great tokens with great communities).
I was able to finally fix it, after a week of mental agony (also the txn finally processed 1-2 hours before I found the solution, robbing me of the gratitude of fixing it myself... (╯‵□′)╯︵┻━┻ ...but now I guess I can hopefully save some of you the headaches that I endured... ) I’m providing the ability to do the same, in a step by step guide.
Why did I go through all of this trouble? I'd fault the fact that I have ADHD and autism, which in my case can multiply each other’s intensity and cause me to “hyper-focus” on things, much much more than most with the same qualities, intentionally or not. Adderall is supposed to give me a bit of control over it, but except for in a very-generalized way, it’s still 90% up to chance and my default-capabilities to allow me control over my attention with self-willpower. But also Karma and Moons pls... ʘ‿ʘ
 
  1. In MyCrypto, (I'm using the Windows 10 app, version 1.7.10) you will open to a screen that says "How would you like to access your wallet?". Choose Ledger, of course. (Unless your here for some non-ledger issue? Idk why you would be but ok.)
  2. On the next screen (having your nano already plugged in, unlocked, and opened into the Ethereum app) click "Connect to Ledger Wallet"
  3. A screen overlay should appear, titled: "Select an Address". Here is where it may get confusing for some users. Refer to "AAA" below to know how to find your account. (Geez, sorry lol that was a huge amount of info for a reddit reply; I might've over-elaborated a little bit too much. but hey it's valuable information nonetheless!)
  4. After escaping the "AAA" section, you'll have accessed your account with MyCrypto. Awesome! To find your ERC20 tokens, (slight evil-laughter is heard from an unidentifiable origin somewhere in the back of your mind) go to "AAB".
  5. (You may have decided to find the token(s) on your own, rather than daring to submit to my help again; if so, you may pity those who chose the other path... ~~( ̄▽ ̄)~~) Now, once you've added your token, you should revert your attention to the account's transfer fill-out form!
  6. I'll combine the steps you probably understood on your own, already. Put in the address that your stuck transaction is still trying to send currency to. If an ERC20 token is involved, use the drop-down menu to change "ETH" to the token in trouble. Input your amount into the box labeled... wait for it... "Amount". Click on "+Advanced".
  7. Refer to Etherscan.com for the data you will need. Find the page for your "transaction(txn) hash/address" from the transaction history on the wallet/Ethereum-manager you used to send from. If that is unavailable, put your public address that your txn was sent from into the search tool and go to its info page; you should be able to find the pending txn there. Look to open the "more details" option to find the transaction's "Nonce" number.
  8. Put the nonce in the "Nonce" box on MyCrypto; you will contest the pending txn with a new txn that offers larger gas fees, by using the same nonce. If (but most likely "When") the new transaction is processed first, for being more miner-beneficial, the nonce will then be completed, and the old transaction will be dropped because it requests an invalid, now-outdated nonce. Your account will soon be usable!
  9. Go to the Gas Tracker, and it may or may not provide an informative reading. Choose whatever amount you think is best, but choose wisely; if you're too stingy it may get stuck again, and you'd need to pay another txn's gas to attempt another txn-fix.
  10. At the time I write this, I'd recommend 50-100 gwei; to repeat myself, gas requirements are insane right now. To be safe, make the gas limit a little higher than MCW's automatic calculation, you may need to undo the check-mark for "Automatically Calculate Gas Limit".
  11. Press "Send Transaction"!!!
  12. You will need to validate the action through your nano. It will have you validate three different things if you are moving an ERC20 Token. It's a good idea to verify accuracy, as always.
 
Well, I hope this worked for you! If not, you can let me know in a reply and I'll try to figure it out with you. I like making these in-depth educational posts, so if you appreciate it please let me know; I'll probably make more posts like this in the future!
( Surely this is at least far better than Ledger's "Support" article where they basically just tell you "Yeah, we haven't bothered to make a way to manually select nonces. I guess we might try to make that available for Bitcoin accounts at some point in the future; who knows? lol"... that's not infuriating at all, right?)
 
AAA:
Before I tell you how to find your address, I will first make it clear, within the italicized text, exactly which address you are looking for, if you are not already sure:
You may also skip the text written in italics if your issue does not include an ERC20 token, if you wish.
Ledger Live can confuse some users with its interface. On LL, to manage an ERC20 token, you first must go to your Ethereum account and add the token. When you then click on the added token under "Tokens" below the graph chart for your account's ETH amount over time, the screen will then open a new screen, that looks just the same, except focused on the specific ERC20 token. To confuse users further, there is then an option to "Star account", which then add the ETH icon with the ERC20 token's first letter or symbol overlapping, onto the easy access sidebar, as if it was another account of similar independency to the ETH account it was added to.
This improperly displays the two "accounts" relation to each other.
Your ERC20 holdings (at least for any and all ERC20 that I know of) are "held" in the exact-same address as the Ethereum address it was added to, which also "holds" any Ether you've added to it. You send both Ether (ETH) and any ERC20 Tokens to and from only Ethereum addresses of equivalent capabilities, in both qualities and quantities. In all basic terms and uses, they are the same.
So, to know what the problematic account's address is, find the address of the Ethereum account it was added to in Ledger Live.
Now, to find your address on MyCrypto, the most reliable way to find it, that I am aware of, is this:
Open Ledger Live. Go to the screen of your Ethereum address (again, this is the one that you added your ERC20 token, if applicable. If you're not dealing with an ERC20 token, you may ignore everything I've put in Italics). Click on "Edit account"; this is the icon next to the star that may look like a hex-wrench tool. On the new screen-overlay, you will see "> ADVANCED LOGS". Click on the ">" and it will point down while revealing a drop-down with some data that you may or may not recognize/understand. Likely to be found indented and in the middle-ish area, you will see this line, or something hopefully similar:
"freshAddressPath": "44'/60'/X'/0/0",
The "X" will probably be the only thing that changes, and the actual data will have a number in its place; it will not be a letter. Let's now put that line to use in MyCrypto:
Take the 44'/60'/X'/0/0 , and make sure you DO NOT copy the quotation marks, or that comma at the end either.
You can do this before or after copying and/or pasting, but drop the second "/0" at the end; it was not necessary in my case, I expect that you won't need it either, and will probably just make MyCrypto see it as an invalid input.
Okay, now go back to the "Select an Address" screen-overlay in MyCrypto.
Next to "Addresses", click on the box on the right, and you should be shown a list of options to select from in a drop-down menu.
Scroll all the way down, and you should find the "Custom" option at the very bottom. Select it.
A new box will appear; probably directly to the right of the now-shortened box that now displays the "Custom" option that you just selected. This box will offer an interface for typed input. ...yep... once again, believe it or not, you should click it.
Type " m/ ", no spaces before or after.
Type in or paste the data we retrieved from ledger live.
The box should now hold this:
m/44'/60'/X'/0
Again, X should be a number. In fact, that number is probably equal to the number of Ethereum (not including any ERC20 wannabe) accounts that you've made on Ledger Live before making the one we're working on right now! (1st Eth. Acc. would have: X = 0, 2nd: X = 1, 3rd: X = 2, ...)
Make sure you've included every apostrophe ( ' ), and solidus ( / ); there is NO APOSTROPHE for the "m" at the start and the "/0" at the end!
If you press the enter key or click on the check-mark to the right of where you typed, the appropriate addresses will be generated, and the address you created through Ledger Live should be the first one on the list!
Select your address and press "Unlock", and you are now accessing your account through the MyCrypto app's interface!
 
AAB:
In order to access your ERC20 token, you will need to add them first.
You may have to scroll down, but on the right-side of your unlocked account screen, you'll see a box with "Token Balances" as its header.
Click "Scan for tokens". This may take a short bit of time, and when it's done it may or may not display your ERC20 token. If it worked, you can head on back to the main part.
If you got the result I did, it won't display your token, or, if our result was exactly the same, it won't display any at all. However, you should now have the "Add Custom Token" option available, so see where that takes you.
You should discover four boxes, specified in order (Address/ Decimals / Token_Symbol / Balance). You may only need to fill in the "Address" box, but if you need to fill others, you'll find those with the token's address; here's 2 ways to find it, if you don't already know.
Method I:
Since you've probably already been managing your token with Ledger Live, you can go to the LL screen of your "account" for that token; Right next to the account's icon, and directly above the name, you'll see:
Contract: 0x??????...????????
Yes, go on; click it. You'll find the token's page on Etherscan; this was just a shortcut to the same place that both of the two previously referenced methods lead to. Skip to method... III?
Method II:
Go to Etherscan.com, or a similar Ethereum-blockchain-monitoring website, if you have a different preference. Search for the name of your token, and you should be able to see it as a search result. Activate your search manually of by selecting search option. Continue on with Method III.
Method III (Iⅈ what makes you think there was a third method? I said 2!):
At this point, you should find the "contract address" somewhere on the screen. This is the identity of the creature that breathes life into the token, allowing it to exist within the world of Ethereum. Steal it, and tell MyCrypto that you've left some of "your" tokens in the address of your ledger's Ethereum account. MyCrypto will trust and believe you without any concern or doubt, just by putting "your" contract address in the box for "Address"; it's almost too easy!
Well whaddya know, this one isn't actually too long! Don't tell anyone who may have taken a little longer whilst finding out how to do it themselves, though. There's value in trying to do something on your own, at least at first, so I'll let them think they made the right choice (¬‿¬). But take this star for humbling yourself enough to seek further help when you need it, since that is a very important life skill as well!
(o゜▽゜)o☆
Now, back to the useful stuff at the top...
 
EDIT: A comment below made me realize that this info should be added too. Here is my reply to the comment saying I could just use MetaMask. I said in the title that this guide is for questions where MEW and MetaMask aren’t working, but I guess it’s easy to miss. I used my u/caddark account to respond:
(Using this account because u/caddarkcrypto doesn’t meet the karma/age standards to comment; the post had to be manually approved.)
I guess I didn’t make it entirely clear; sorry:
The target audience for this guide is anyone with a stuck Ethereum transaction that was initiated through Ledger Live AND are experiencing the same difficulties I had encountered while trying to fix this issue for myself.
This wasn’t any regular stuck Ethereum transaction. Apparently before, there was an issue that made a Ledger Nano nearly impossible to connect to MetaMask (which is also Brave Browser’s integrated “crypto wallet” for the desktop version) and/or MEW (also perhaps any other browser wallets made for chrome and/or brave) that I heard was supposed to be fixed in a recent update. It might’ve been mostly patched, idk, but during my experience, (in which I was using the latest version of Ledger Live that is available right now,) that issue still remained.
The really weird part was that it successfully connected to the browser wallets again after I fixed the stuck transaction. At first I thought that somehow the txn was what was bugging the connection. However, later, during no txn issues, I was again unable to connect.
Seeing the same connection error again later, I opened up the MCW app I downloaded the day before, and was going to just use that. While in the process of operating MCW, I suddenly had another idea to try for the browser wallet so I went back to that just to quickly test it.
The browser wallet worked perfectly...
I don’t know how, but I think that somehow, something in MCW’s software, makes the browser wallets work. They don’t work for me without having MCW opened in the background first.
EDIT 2: Markdown decided to stop working after I did the first edit... I might fix it tomorrow... how did that happen though??? What did I do?
EDIT 3: nvm, I'm just fixing it now; I won't get much sleep tonight I guess.

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I originally posted this on cryptocurrency. I just thought you guys might be able to help as well so I posted it as well. I didn't link to the original post because the bot here keeps deleting my post, even if I use the np link. Hope that's ok...
EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [[email protected]](mailto:[email protected]) . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
  1. A logistic and transportation company
  2. A delivery company
  3. A company that buy and sell real estate options
  4. A company that manage real estate
  5. A software development company
  6. A world-wide fiat money transfer company
  7. A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [[email protected]](mailto:[email protected]) .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.

4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?
