Blocknet

Build Status

https://blocknet.co

Welcome to the Blocknet repository. This repo is for the Blocknet Protocol, a 2nd layer blockchain interoperability protocol that enables communication, interaction, and exchange between different blockchains. This allows for the development of multi-chain applications and blockchain microservices, creating exponentially more capabilities and possibilities for the blockchain ecosystem.

Contributors are welcome!

Blocknet

Started in 2014, Blocknet is a decentralized, community-governed, self-funded, open-source project that serves as a connector between different blockchains, markets, and communities.

The Blocknet Protocol

The Blocknet Protocol enables decentralized communication and exchange between different blockchains in a permissionless and trustless manner through the use of the TCP/IP networking layer for communication, P2P atomic swaps using BIP65 for exchange, and a DHT overlay network (Service Nodes) to host the full nodes of compatible blockchains, host microservices, audit interactions, and perform anti-spam and anti-DOS measures for the network.

Block DX

Block DX is a completely decentralized and trustless exchange built on the Blocknet Protocol that mimics a centralized exchange experience and enables traders to conduct exchanges directly from the wallets of the coins being traded. View Repo: [https://github.com/BlocknetDX/block-dx]

Decentralized Atomic Swap Algo Summary

Initiator creates secret X, and hashes it to create H(X). Initiator also creates public private key pair (pubkey i1,i2 / privkey i2,i2). Responder creates public private key pair (pubkey r1,r2 / privkey r1,r2).

Step 2.
Initiator shares H(X) and pubkey i2 with responder. Responder shares pubkey r1 with intiator.

Step 3.
Initiator creates TxAb. TxAb can be redeemed after time T2 with privkey i1. At any time TxAb can redeemed with signature from privkey r1 and reveal of secret X. Initiator broadcasts TxAb onto the network.

Step 4.
Responder confirms TxAb. Responder creates TxBb. TxBb can be redeemed after T1 time with privkey r2. At any time TxBb can be redeemed with signature fom privkey i2 and reveal of secret X. Responder broadcasts TxBb onto the network.

Step 5.
Initiator creates TxBp which spends TxBb using privkey i2 and secret X. With the revealed secret, responder can create TxAp which spends TxAb with privkey r1 and secret X.

Development Process

The master branch is stable and will match the latest release. Development branches are indicated by the version number and may or may not be stable. Tags are created regularly to indicate new official, stable release versions of Blocknet.

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.
