Updates

First Halving ✅ 

CKB successfully underwent its first halving at block 11487788🚀 (17:23:47 November 19th, UTC+0000).

Features

• Daemon Process Support
  • CKB can now run in a daemon process independently of systemd.
  • Support easy run daemon mode for Linux/MacOS #4245
• Skip Previous Block Synchronization
  • The init tip feature facilitates direct database initialization for better performance in terms of time and space.
  • feat: introduce init_tip_hash setting for indexer to skip previous block synchronization #4247
• Background Mode for Migration
  • To manage lengthy migrations, a background running mode has been implemented.
  • Add migration run in background mode #4226
• Toncoin Support
  • ckb-auth now supports and provides documentation for Toncoin.
  • Add Toncoin support ckb-auth#18

Fixes

• Several fixes have been implemented in both ckb-core and faster-hex, improving stability and performance:
  • ckb-core
    • Fix CheckVmBExtension failed on CI #4241
    • Fix using journalctl to check the log of ckb.service #4238
    • feat: update mainnet bootnodes list #4228
    • fix: dummy block reward #4227
  • faster-hex:
    • reduce scope of unsafe xsave code to where know it's supported faster-hex#39

Improvements

• Continuous improvements in ckb-core are focused on enhancing efficiency and dedv experience:
  • Break ckb-launcher and ckb-chain's cycle dependency by moving SharedPackage and SharedBuilder from ckb-launcher to ckb-shared #4236
  • RBF will also replace tx not in Pending #4231
  • Improve exit signal related log message #4240

In Pipeline…

• New Indexer Based on Relational Database
  • Working on a new indexer for CKB based on a relational database to enhance data retrieval efficiency.
  • feat: add rich-indexer which is another built-in indexer based on relational database #4224
• Asynchronous Block Downloading and Verification
  • We're designing a new system that will allow the asynchronous downloading of CKB blocks and parallel verification. This separation of I/O operations from computations will maximize the performance of CKB nodes.
• Replacing jsonrpc with jsonrpc-utils
  • This change aims to simplify maintenance and enhance CKB RPC's compatibility with JsonSchema.
  • Use jsonrpc-utils to replace jsonrpc #4170
  • Add openrpc generator and use JsonSchema to update rpc/readme #4187
• Ongoing Research and Design Efforts
  • Designing composable CKB dApp patterns.
  • Exploring the integration of libp2p as a network library for CKB, aiming to improve network capabilities.
  • A Tui for CKB for better user and maintenance experience.
