Resilient & Permanent: An AI-Rendered Vision of My Concept for CKB as a Facility - @EthanYuan

Updates

Proposal

• xUDT(Extensible UDT) Proposal
  • The proposal on xUDT, an advancement over the Simple UDT for Nervos CKB, is now ready for review. xUDT aims to provide extended functionalities for UDTs, particularly in regulatory aspects.
  • Join the discussion: [0052] Extensible UDT rfcs#428

Features

• CKB Light Client v0.3.5
  • This update brings crucial bug fixes and performance enhancements.
• ckb-transaction-dumper v0.4.0
  • Offering full transaction data compatibility with the ckb-standalone-debugger, along with various improvements including Windows support.
• ckb-script-templates
  • Introducing template generator for developing CKB contracts in mainstream development environments using Rust & clang C compiler.

Improvements

• Omnilock Script
  • Added auth algorithm IDs for following blockchains:
    • Bitcoin
    • Tron
    • Dogecoin
    • Ethereum
  • Enhanced transaction signing messages for BTC and ETH.
  • Add missing auth id(0x02~0x05) cryptape/omnilock#2
• CKB Indexer
  • Enabled the filtering of cells based on output data, improving data querying efficiency.
  • feat(indexer): support cell data filter #4303

Fixes

• CKB Transaction Pool - RBF Enhancements
  • Improved Replace-by-fee fee checks to handle complex scenarios such as child-pay-for-parent transactions.
  • Fix RBF fee and celldeps check rule issue with replaced txs and their descendants #4306

Ongoing…

• CKB CoBuild Protocol

  The CKB Transaction Co-Build Protocol is designed for building CKB DApp. As an off-chain protocol, it serves to standardize the process of collaborative CKB transaction creation among multiple parties. Provides a common framework for transaction building and signing.

  • Proof of concept
    • Integrated Open Transaction (OTX) lock script to ckb-transaction-cobuild-poc
    • feat: add otx lock poc cryptape/ckb-transaction-cobuild-poc#41
  • Demo: Managing DAO deposits
    • Integrate OKX wallet to DAO Co-build protocol demo and updated UniSat's deployment
    • ✨ Migrate to Omnilock cryptape/ckb-dao-cobuild-poc#13
    • ✨ Add OKX BTC cryptape/ckb-dao-cobuild-poc#15
  • Molecule Dynamic Visitor
    • Schema designed to convert complex transaction messages into a readable format
