Updates

Features

• New releases:
  • ckb v0.114.0
  • ckb-cli v1.7.0
  • ckb-sdk-rust 3.1.0

Improvements

• Transaction Pool:

  • Compact Block Success Rate: Identified and improved the compact block reconstructing success rate issue during the Omiga Incription launch by adding a transaction conflict cache.

    Add conflicts cache for tx_pool to record conflicted transactions #4339

  • Conflict Resolution Algorithm: Implemented a new algorithm to resolve conflicts when a cell is utilized both as cell deps and inputs across different transactions.

    Evict possible cell ref txs before submitting cell consuming transaction #4363

• Contracts Maintenance:

  • Omnilock: Switched to the llvm toolchain.

    Support llvm-toolchain XuJiandong/omnilock#23

  • ckb-auth: Removed the secp256k1 precomputed table to streamline operations.

    Minimize secp256k1 precomputed table ckb-auth#43

• CKB Cli:

  • Dev Chain: Proposal to adjust the default parameters to make local development easier

    chore(dev chain): Adjusting the default dev chain epoch parameter #4366

Fixes

• Background Migrations: Updated the logic so it will not block node upgrading by default.

  Add --include-background to include background migrations in migrate subcommand #4343

• Peer Management: Fix a bug that a misbehaving peer is not banned.

  A peer send malformed tx with large cycles will also be banned #4347

• RPC Documentation: Fix a bug in the RPC documentation generator.

  Support RPC duplicate method name for different modules #4341

In Pipeline…

• Spawn Syscall Enhancement: Continues the work based on the prototype.
  • Improved the scheduler and finished the testing.
  • Started the syscall spawn implementation.
• Script Verification Performance: Improving performance to verify script that takes large amount of cycles.
  • Code reviewing on the PR New script verify with ckb-vm pause #4291
  • Benchmarked to ensure it will not cause performance degration on normal transactions.
• Rich-Indexer: Aims to complement the original indexer with support for more complex queries, leveraging a relational database.
  • feat: add rich-indexer which is another built-in indexer based on relational database #4224
  • Fixed errors reported by compilers and linters.
  • Luanched acceptance test on the project.
• Asynchronous Block Handling: Efforts are underway to make block downloading and verification asynchronous, promising significant enhancements to the synchronizer and ChainService. Progress of the last month:
  • Released an RC version and started to test it in the testnet environment.
  • Improved the bootstrap algorithm when async block downloading starts.
• Payment Channel Network for CKB: PCN allows for fast and efficient transactions between parties by creating off-chain payment channels.
  • Bootstraped the project and fininshed the research phase.
  • Started the design and MVP development phases.
• CoBuild: The CKB Transaction CoBuild Protocol describes an off-chain procedure for multiple parties to collaboratively create a CKB Transaction.
  • Finished the support of CoBuild in Omnilock and calling for review: Implement Cobuild integration and Solana support cryptape/omnilock#3
  • Added test cases and fininshed the support of CoBuild OTX in Omnilock: Support cobuild OTX XuJiandong/omnilock#18
  • Developing a PoC to construct multisig transactions using CoBuild lock actions: Transaction management cryptape/ckb-multisig-cobuild-poc#2
• CKB Memory Usage Issue: Working on the received report on the increasing memory usage in the new CKB versions since v0.110.0.
