About Qtum and Mainnet Ignition

Qtum is a decentralized blockchain project built on Bitcoin's UTXO model, with support for Ethereum Virtual Machine based smart contracts, and secured by a proof of stake consensus model. It achieves this through the revolutionary Account Abstraction Layer which allows the EVM to communicate with Qtum's Bitcoin-like UTXO blockchain. For more general information about Qtum as well as links to join our community, go to https://qtum.org

Welcome to the Qtum Ignition Main Network. This is the main network where the tokens hold value and should be guarded very carefully. There will be a testnet setup soon for developers, in the meantime you can use -regtest mode for testing needs. We will announce details about the token swap from QTUM ERC20 coins to QTUM mainnet tokens soon, watch our website for details about that.

The major features implemented in Qtum Ignition include:

  1. The Ethereum Virtual Machine, which allows for compatibility with most existing Solidity based smart contracts.
  2. The Smart Staking Protocol is complete, which is an optimized Proof of Stake implementation designed for a smart contract platform (however, smart contracts can not participate in staking yet).
  3. An early and basic smart contract GUI has been implemented that can be used for creating contracts, sending data and Qtum to them, and checking their status by executing them locally. This functionality is similar to Mist's UI right now, but it is still an early version. We will be working on this more to improve it.
  4. Regtest mode, which is ideal for developers who wish to create their own private blockchain. It is tuned specifically to make development easier. It will stake blocks automatically every 30 seconds, and can generate proof-of-work blocks instantly as needed.
  5. The Decentralized Governance Protocol is completely implemented and functional, which allows certain network parameters to be modified without a fork.

For more technical information for how to start developing with Qtum please read the Guide and also see this tutorial for deploying a simple faucet smart contract (it hasn't yet been updated for Mainnet for obvious reasons, but all the instructions are the same and you can try them in regtest mode)

Note: Qtum Core is considered beta software. We make no warranties or guarantees of its security or stability.

Update History

  • v0.14.12 - Recommended Update
    • Added option to disable change address usage
    • Fixed bug where heavy RPC usage could cause the wallet to crash
  • v0.14.11 - Optional Update
    • Changed our versioning scheme to be consistent and avoid the two version number confusion
    • Add feature to restore wallet in the Qt wallet
    • Add new RPC call "waitforlogs" that is particularly useful for Dapp developers
    • Add long-polling support to the gettransaction RPC call
  • v1.1.4 - Recommended update
    • Fixed a bug that would cause syncing to stop
    • Fixed a bug that would cause the wallet to crash when using -logevents
  • v1.1.3 - Highly recommended update
    • Fixed a bug that caused contact addresses to show in receive token address dropdown
  • v1.1.2 - Optional update, but recommended if using QRC tokens
    • Fixed a bug with token transactions where the transaction ID displayed was incorrect in the Qt wallet
    • Allow adding 0 balance addresses as the token receiver in the Qt wallet
  • v1.1.1: When sending to contracts, the sender address is now the default change address to reduce confusion; fix -salvagewallet so it works with token transactions
  • v1.1.0: Add GUI support Qtum QRC tokens, allowing full management of tokens on the Qtum blockchain from the Qt wallet
    • Sending to a contract no longer requires ABI data, allowing easy participation in simple crowdsale contracts
  • v1.0.4: Fix bug where certain circumstances when staking could cause the displayed balance to be inaccurate until completely redownloading the blockchain.
  • v1.0.3: Fix staker bug that reported false messages; slightly increases staking performance; optimize staker parameters; fix white send button in GUI
  • v1.0.2: Various UI fixes, minor gas overflow consensus fix, per-txout exploit fix, testnet mode setup and functioning
  • v1.0.1: Fixed network magic bytes and minimum version to ensure the main network does not conflict with the Skynet network
  • v1.0: Initial release

Reindex Required When Upgrading from v1.0.1

When you first start the Qtum 1.0.2 GUI wallet after using Qtum v1.0.1 it will prompt you that it must reindex the database. This is normal and is a result of switching our internal database format from per-transaction to per-txout. If you use qtumd -daemon it will silently fail to start. You need to use qtumd -daemon -reindex in this case.

General Info about Qtum:

Quickstart

The easiest way to get started with Qtum is to simply download the binaries below. To give a brief breakdown of the different versions available:

Windows

  • qtum-0.14.12-win64.zip - A version of Qtum-Qt, qtumd, and qtum-cli built for 64bit x86 machines using Windows.
  • qtum-0.14.12-win64-setup-unsigned.exe - A version of Qtum-Qt, qtumd, and qtum-cli built for 64bit x86 machines using Windows. This includes an installer and will install Qtum system wide.
  • qtum-0.14.12-win32.zip - A version of Qtum-Qt, qtumd, and qtum-cli built for 32bit x86 machines using Windows. If you have an older Windows computer and don't care about installing Qtum system-wide,
  • qtum-0.14.12-win32-setup-unsigned.exe - A version of Qtum-Qt, qtumd, and qtum-cli built for 32bit x86 machines using Windows. This includes an installer and will install Qtum system wide. If you have an older Windows computer and want to install Qtum then this is for you.

OSX

  • qtum-0.14.12-osx64.tar.gz - A version of Qtum-Qt, qtumd, and qtum-cli built for 64bit x86 machines using OSX. If you use a modern Mac and want development tools, this is what you want; we do not support older 32bit or PowerPC based Macs.
  • qtum-0.14.12-osx-unsigned.dmg - A version of Qtum-Qt built for 64bit x86 machines using OSX in a .DMG installable format. If you use a modern Mac and aren't a developer, this is what you want; we do not support older 32bit or PowerPC based Macs.

Linux

Below in the full list of binaries, there are also versions that include debug symbols. These are useful for developers, but will run slower and are significantly larger to download.

Build Qtum Core

If you want to build it from source, it's recommended to follow the specific "build" documentation for your platform. But mostly it boils down to the following:

  1. Clone the qtum source code and cd into qtum

     git clone --recursive https://github.com/qtumproject/qtum.git
 cd qtum

  2. Build qtum-core:

    Configure and build the headless qtum binaries as well as the GUI (if Qt is found).

    You can disable the GUI build by passing --without-gui to configure.

    ./autogen.sh
./configure
make

  3. It is recommended to build and run the unit tests to ensure everything is working correctly:

    make check

If you encounter an error like:

make[2]: *** No rule to make target ‘cpp-ethereum/utils/libscrypt/b64.c’, needed by ‘cpp-ethereum/utils/libscrypt/libbitcoinconsensus_la-b64.lo’. Stop.

Then you did not checkout the cpp-ethereum submodule for Qtum. To do that, simply:

cd qtum
git submodule update --init --recursive

Validate and Reproduce Binaries

Qtum uses a tool called Gitian to make reproducible builds that can be verified by anyone. Instructions on setting up a Gitian VM and building Qtum are provided in doc/gitian-building.md

Community Resources

Make sure to check out these resources as well for more information and to keep up to date with all the latest news about Qtum. At least 1 developer is always around, so if you're developing on Qtum and need help, we'd love to welcome you to our community.

Qtum Smart Contract Limitations

  • EVM smart contracts can not receive coins from or send coins to any address type other than pay-to-pubkeyhash (starts with Q) addresses. This is due to a limitation in the EVM
  • Contracts are not allowed to create contracts with an initial endowment of coins. The contract must first be created, and then be sent coins in a separate transaction. Humans are also not allowed to create contracts with an initial endowment of coins.
  • Although all of the infrastructure is present, Qtum Core does not currently parse Solidity event data. You must parse this yourself using either searchlogs or -record-log-opcodes features.
  • It is not possible to send a contract coins without also executing the contract. This is also the case of Ethereum. This was promised in earlier discussions and technically does work, but due to lack of time for testing this feature was disabled. We hope to reenable this feature with release of the x86 virtual machine in 2018.
  • In Qtum there can be multiple addresses used to create a proof-of-stake block. However, the EVM can only see the first output using the coinbase operation in Solidity (this address is also the one registered for the continuous staker rewards after 500 blocks).
