Blockchain — Blockchain-CN

Blockchain-CN is a Go-based blockchain node implementation that lets users run nodes, connect peers over TCP, and use HTTP endpoints to join peers, create blocks and inspect chain data. Its README demonstrates block propagation between two connected nodes.

Practical overview

When it fits

Use it when you want a small, self-hosted Go example for exploring node startup, peer joining, HTTP control and block propagation.

Who it is for

  • Developers learning how a basic blockchain node and peer-to-peer block propagation work
  • Prototypers exploring local multi-node networks, peer joining and HTTP control of nodes

Documented uses

  • Build and start local blockchain node processes
  • Connect one node to a peer using its address
  • Create a block through an HTTP request
  • Inspect chain data on connected nodes to observe propagation
Before you choose

Requirements & limits

The repository is public and identified as open source; no license is specified in the supplied project evidence.

  • The documented node uses separate HTTP control and TCP peer-to-peer ports.
  • The README provides a command-line build and curl-based examples for joining, creating and viewing blocks.
  • The demonstrated chain includes a default genesis block and a simple block model.
  • The examples cover a basic two-node workflow rather than a broader production deployment.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build and connect two local nodes

Start two nodes, connect one as a peer, create a block and inspect the chain shown by each node.

Before you start

  • Go build environment and command-line access
  • Two node processes with separate HTTP control and TCP peer ports
  • A reachable peer IP address for the join request
  • curl for the documented HTTP requests

Steps

  1. Build the repository with the command below.

    Documented command
    go build

  2. Start two node processes with distinct -server and -p2p ports, as in the README example.

  3. Send a POST request to /blockchain/join on the first node with the second node’s TCP address as peer_addr.

  4. Use /blockchain/create to publish a block, then POST to /blockchain/show on both nodes to inspect their chains.

Expected outcome

The README’s example shows the created block appearing in both nodes’ chain output after peer connection and propagation.

Guide limitations

  • The steps reflect the repository README; they are not execution-tested here.
  • The README demonstrates two connected nodes and a basic chain, not production deployment or broader network operation.
  • The repository evidence identifies no license.
