What is Syscoin?

Syscoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Syscoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Syscoin Core is the name of open source software which enables the use of this currency.

For more information, as well as an immediately useable, binary version of the Syscoin Core software, see https://syscoin.org/, or read the original whitepaper.

Syscoin is a merge-minable SHA256 coin which provides an array of useful services which leverage the bitcoin protocol and blockchain technology.

Hybrid layer 2 PoW/PoS consensus with bonded validator system (masternodes) ZDAG technology for point-of-sale speeds and probabilistic confirmations useful for microtransactions Trustless sidechain access to Ethereum and back through a custom permissionless/trustless sidechain technology (SYSX bridge) https://github.com/syscoin/sysethereum Decentralized governance (blockchain pays for work via proposals and masternode votes) Digital asset creation and management. ZDAG is open-source and developed over the course of 12 months by Blockchain Foundry Inc, with external audit done over 6 months by Whiteblock. Performance report can be found here.

Governance formula: We have implemented a % decline schedule — starting the first month with 1500000 SYS and ending on the 24th month with 196708 SYS. After that period, the superblock starts with 151767 SYS a month and will decline 5% every year. Read more about it here: https://medium.com/@syscoin/syscoin-4-0-rewards-specifications-a3dc01d85adf.

Interoptibility through a trust-less, no custodian, no counterparty bridge to Ethereum. Existing ERC20 assets can move to and from Syscoin Platform Tokens at will. This is the first time a fractional supply, two-way bridge has been developed and brought to market. It will enable a scaling infrastructure for Ethereum as well as flexibility for existing Syscoin ecosystem. A sharing and collobrative approach to foster growth in the industry was the goal, this is the results of over 18 months of research and development by Blockchain Foundry Inc. Documentation can be found here.

The bridge allows existing ERC20's following the standard spec EIP-20 to trust-lessly move across chains. This is different than other projects that use custodians (operators that are in control of the movement of funds), which can cause theoretical attacks especially as value of transfers increases. Our implementation relies on PoW as the absolute security mechanism which is tried, tested and true from Nakamoto consensus used in Bitcoin. Either side uses SPV proofs while having knowledge of the longest chain. On Ethereum, Syscoin block headers are saved in a smart contract to validate against SPV proofs and on Syscoin, nodes are listening to the Ethereum network natively through Geth light nodes. This way we have absolute knowledge of the chains when validating SPV proofs and no external parties are needed to attest on the longest chain. See documentation for more details.

License

Development Process

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of Syscoin Core.

The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.

Testing

Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python, that are run automatically on the build server. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Translations

Changes to translations as well as new translations can be submitted to Syscoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.

Translators should also subscribe to the mailing list.
