Updates

• Released CKB v0.110.0

Features

• Open Transaction Web App could call signer plugin’s RPC to retrieve a list of unsigned transaction requests from the Open Transaction pool
  • feat: allow signer plugin to open its own rpc services EthanYuan/open-transaction-pool#8
• A framework for constructing simple multisig transaction in Rust
  • simple multisig transaction builder ckb-sdk-rust#68
• A Rust implementation of a Java-style transaction builder
  • This separates the process of building a transaction into three steps: build, sign, and send
  • Feat/refact build sign send 20230418 ckb-sdk-rust#66

Improvements

• Reduced peak memory usage during Initial Block Download (IBD) synchronization - from 3.8GB down to 2.8GB
  • This was achieved by replacing the HeaderView structure in the sync module with a more memory-efficient alternative, HeaderIndexView
  • refactor(perf): replace sync struct HeaderView with HeaderIndexView #3970
• Added support for the following RPC methods in Rust, Java, and Go:
  • get_transaction_and_witness_proof - returns a Merkle proof of transactions’ witness included in a block)
  • verify_transaction_and_witness_proof - verifies that a proof points to transactions in a block, returning the transaction hashes it commits to
• Introduced multiple indexes in SortedTxMap of the transaction pool in preparation for future sorting strategies
  • Improve tx pool index for different sorting strategies #3971
• A new parameter has been added to the get_transaction RPC
  • Allowing developers to easily specify a "committed transaction" when querying from the transaction pool
  • rpc(ChainRpc): Add only_committed param for get_transaction #3963
• Updated the documentation, tools, and tests of the CKB-Auth library
  • Add CI : auth_spawn_rust and update toolchain cryptape/ckb-auth#4
  • Add docs cryptape/ckb-auth#2
• Refactored code for CKB Combine Lock
  • Update capsule to v0.10.0 and ckb-std to v0.13.0 cryptape/ckb-combine-lock-poc#30

Fixed

• Implemented a minor fix for the hardfork during code review
  • Trivial fix for ckb2023 #3976
• Fixed the bug that prevented the dao handler from getting the correct withdraw block hash.
  • fix: 🐛 Make dao handler get correct withdraw block hash ckb-sdk-java#642

In pipeline…

• CKB 2023 edition (HF)
  • ckb 2023 edition #3917
• Enhanced UI for CKB Full Node Probe (previously CKB Analyzer), that displays CKB node distribution in cool graphics
• Open Transaction
  • A MVP of Open Transactions P2P network
    • Working on a Rust function to verify the transactions in groups, its output will be used to evaluate the value of OTXs for the filtering and reputation system of P2P network
    • P2P MVP EthanYuan/open-transaction-pool#6
• The CKB Combine Lock script that lets you combine different signature algorithm scripts and easily verify them all together
• Mock testing Light Client in ckb-sdk-java
  • Update Gradle version to 7.6 and resolve the issue of unsigned auto-deployment
  • Update gradle to 7.6 ckb-sdk-java#637
