Updates

Features

• CKB Light client has been updated to incorporate the the changes from the CKB2023 Hardfork
  • feat: tweak SendBlocksProof message to support ckb2023 #4185
  • Upgrade ckb dependencies to 0.111.0, use cargo-nextest to run unit tests ckb-light-client#153
• Open-sourced CKB-JS-VM, empowering the execution of JavaScript within on-chain smart contracts.
  • Take a look at a simple UDT implementation in JavaScript and expect more examples and comprehensive tests to come.
  • Add simple UDT example ckb-js-vm#2
• CKB-Auth now supports EOS signature verification
  • Support EOS ckb-auth#13

Improvements

• Light Client
  • Optimized block requests to CKB full nodes by requesting only the blocks that match specific filters.
    • chore: only fetch blocks for filter matched ckb-light-client#154
  • Refined to ensure it only returns data from the main chain, enhancing its accuracy.
    • fix: should only return main chain data #4182

Fixes

• Tweaked the consensus structure in CKB and resolved broken tests introduced in CKB v0.110.2, ensuring the system's stability.
  • Remove Consensus.dao_type_hash's Option wrapper #4186
• Addressed a sporadic CKB integration test failure, improving the reliability of our platform.
  • Fix RBF spec test failed issue #4183

In Pipeline…

• 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.
• Updating CKB to statically link OpenSSL, which offers improved security and efficiency. This update also extends to the CKB Docker container image and the ckb-cli binary.
  • WIP: Upgrade OpenSSL from 1.1.1 to 3.1.3 #4179
• Fine tuning the bloom filter used in ckb-rocksdb for better performance
  • WIP: performance: tuning rocksdb bloom filter #4191
• Migrating from jsonrpc to jsonrpc-utils as the RPC framework to enable support for more upcoming features
  • WIP: Use jsonrpc-utils to replace jsonrpc #4170
• Enhancing CKB RPC by adding support for JsonSchema, making it easier to validate and work with JSON data.
  • WIP: Add openrpc generator and use JsonSchema to update rpc/readme #4187
