Sound Money & Robust Programmability

Infinite scalablilty for financial inclusion With native smart contracts and robust architecture, XGT supports up to 3,000 transactions per second and a financially-inclusive experience for all users.

Dockerized libraries for egalitarian opportunity to run full nodes: An XGT daemon can be easily run with the provided Docker images, which enables exchanges, developers and applications to integrate and run XGT with unparalled efficiency, while also embracing reliability as a key security measure. Deploying and maintaining an XGT node is simple enough that anyone can do it.

Optimal governance for egalitarian participation: XGT will be supported by an unlimited number of nodes run by developers, applications, users and miners. Miners produce the blocks that track all XGT transactions at a rate of one block every three seconds and there is no limit on the number of miners. Together these nodes provide growing decentralization and security to XGT.

Streamlined full nodes for perfect app integration: The advantage of XGT nodes is that they are extremely quick to set up, inexpensive to operate or migrate to, and highly responsive relative to other networks. Better still, the open nature of the network means that it is available to all, and participants are not subject to the behaviour of a group of insiders. Anyone can operate a full node, or mine using the open source software. XGT is built with the knowledge that the benefit of a full node designed specifically for economic purposes, knowing full well non-economic data needs to be supported by off-chain, application-based APIs for optimal performance.

Advantages

  • Fast application and exchange integration: New streamlined blockchain infrastructure based on years of research.
  • Real-time financial inclusion: Three-second block times.
  • Decentralization: Proof of Work for network security, coin supply, and open governance.
  • Revolutionary application development: Off-chain content and on-chain reference-IDs for rewarding community engagement
  • Unlimited financial inclusion:
  • On-chain currency creation with vote-able emissions for community growth via XGT Token Trees
  • Unparalled bridging of applications and blockchain: base58 randomized wallet IDs for privacy and integration with off-chain account systems. Generated with a BTC compliant algorithm, and namespaced with XGT for user-safety

Announcement

XGT was formally announced on BitcoinTalk on May 28, 2021, at 06:56 PM PST.

Installation

Getting started with XGT is fairly simple. You can either choose to use docker-images, build with docker manually or build from source directly. All steps have been documented and while many different OS are supported, the easiest one is Ubuntu 20.04.

Quickstart

Just want to get up and running quickly? We have pre-built Docker images for your convenience. More details are in our Mining XGT Guide.

Building

We strongly recommend using one of our pre-built Docker images or using Docker to build XGT. Both of these processes are described in the Mining XGT.

To build from source, we also have build instructions for Linux (Ubuntu 20.04 LTS) and macOS.

Dockerized Mining

See Mining XGT

CLI Wallet

We provide a basic cli wallet for interfacing with xgtd. The wallet is self-documented via command line help. See xgt-ruby

System Requirements

4GB memory (16GB recommended) x86 or AMD64 compatible CPU

xgt's Issues

Reduce block generation rate

In order to smooth out block production performance rate,
Difficulty should be adjusted every 2016 blocks.

Given the current difficult adjustment period is 2016*150,
Then the adjustment period should be 2016 blocks.

Enable multi-threading on miners

Current mining is single threaded, to be more efficient on network/disk/memory, allow multiple mining threads, configured via config.ini

The following code needs to be added to void witness_plugin::plugin_initialize(const boost::program_options::variables_map& options) in /libraries/plugins/witness/witness.cpp

   if( options.count("mining-threads") )
   {
      _mining_threads = std::min( options["mining-threads"].as<uint32_t>(), uint32_t(64) );
      _thread_pool.resize( _mining_threads );
      for( uint32_t i = 0; i < _mining_threads; ++i )
         _thread_pool[i] = std::make_shared<fc::thread>();
   }

Reduce log output

It's consuming a lot of disk space, and is pretty verbose during normal operation.

Improve log messaging output

The error message:

    {"name":"XGT...","what":"unknown key"}
    database.cpp:616 get_account
3061638ms database.cpp:1073             notify_pre_apply_tra ] Caught exception in plugin: 13 N5boost10wrapexceptISt12out_of_rangeEE: unknown key
unknown key:
    {"name":"XGT8CW6Pk3wDAwwEGbMZhXo2RvfztV9gGzT2ByN78DG","what":"unknown key"}
    database.cpp:616 get_account
rethrow
    {}```

Should produce a smoother log output, or none at all.

Nakamoto difficulty not working as intended; replace difficulty logic

Adjust difficulty every two weeks, according to the nakamoto difficulty adjustment routine.

The pseudo code for this is as follows:


if (timespan < targetTimespan / 4) 
  timespan = targetTimespan / 4
if (timespan > targetTimespan * 4)
  timespan = targetTimespan  * 4

newDifficulty = (lastBlockDifficulty * actualTimespan) / targetTimespan;

if (newDifficulty > powLimit)
  newDifficulty = powLimit;

Based on this code from bitcoin-core:

unsigned int CalculateNextWorkRequired(const CBlockIndex* pindexLast, int64_t nFirstBlockTime, const Consensus::Params& params)
{
    if (params.fPowNoRetargeting)
        return pindexLast->nBits;

    // Limit adjustment step
    int64_t nActualTimespan = pindexLast->GetBlockTime() - nFirstBlockTime;
    if (nActualTimespan < params.nPowTargetTimespan/4)
        nActualTimespan = params.nPowTargetTimespan/4;
    if (nActualTimespan > params.nPowTargetTimespan*4)
        nActualTimespan = params.nPowTargetTimespan*4;

    // Retarget
    const arith_uint256 bnPowLimit = UintToArith256(params.powLimit);
    arith_uint256 bnNew;
    bnNew.SetCompact(pindexLast->nBits);
    bnNew *= nActualTimespan;
    bnNew /= params.nPowTargetTimespan;

    if (bnNew > bnPowLimit)
        bnNew = bnPowLimit;

    return bnNew.GetCompact();
}

blacklist?

Hello,
I have an issue with the miner, somehow I got disconnected from all peers after a few minutes, and all the blocks I find are never taken into account by the network.
This is one of the message I get:
image

And I got this message for every bloc I find.
I made like 1 xgt in 3 days with a 3900X
Is it possible that my ip got blocked by peers?

the project is dead?

Hello!

everything is in the title,
there is no longer any way to mine, and no access to our wallet,

what is the problem?

Docker release protocol updates

Let's make docker better for all!

The instructions at https://xgt-network.github.io/mining/ still refer to version :1.0.7, not the latest version. I'd suggest the latest version of the docker always get tagged as :latest as well, and the instructions updated to refer to :latest instead

  • Update docs for docker per a suggestion from sharky:

With docker you can use -v ${PWD}/xgt-chainstate-0:/home/root/xgt-chainstate-0 or similar to mount a volume mapped to a directory on your host machine, this will let the blockchain data persist even if you remove the docker container and start again

...stop building in the docker image too, just COPY in a binary from CI and only install the necessary deps
