Features

• 4365: Asynchronous Block Download and Verification (@eval-exec)

  This PR introduces several enhancements to the CKB Synchronizer to reduce synchronization time during the initial block download (IBD) phase. Key changes include:

  1. Asynchronous Operations: The Synchronizer sliding window movement is now decoupled from the block verification process in the ChainService, allowing asynchronous handling. This improves the efficiency of block requests and verification.
  2. Changes to sync_state RPC:
     • Added tip_hash and tip_number to represent the current chain tip.
     • Added unverified_tip_hash and unverified_tip_number to track the latest received but not yet verified blocks.
     • Removed the orphan_blocks_size field.
  3. Log Format Update: The format of CKB logs has been updated, specifically changing the prefix and content of log entries to provide clearer and more structured information.

  These updates lead to a more efficient synchronization process, reducing the overall time required for IBD. Note that removing the orphan_blocks_size field constitutes a BREAKING CHANGE in the sync_state RPC.

• 4380: New spawn with scheduler (@mohanson)

  This change is only available in the next version of CKB consensus rules.

  In this PR, we refactored the implementation of spawn. The refactored syscall API is defined as follows: https://github.com/XuJiandong/ckb-c-stdlib/blob/syscall-spawn/ckb_syscall_apis.h#L54-L68.

• 4291: New script verify with ckb-vm pause (@chenyukang)

  1. Use a job queue for pending transactions waiting for verifying
  2. Multiple workers trigger the verification process by picking task from queue
  3. Verification is changed to async style
  4. Use channel to resume/suspend vm
  5. No snapshot from VM machines
  6. No Suspend state from cache
  7. All transactions from remote peer will be added into queue

Bug Fixes

• 4562: Fix sync relayer collaboration (@driftluo)

• 4576: Add limit to get cells (@driftluo)

  This is a breaking change to RPC. The RPC to get cells may fail when exceeding the limit.

Improvements

• 4529: Add jsonrpc batch request limit (@chenyukang)

• 4583: Add tx_index to TxStatus for get_transaction RPC (@eval-exec)

  This is a breaking change to the RPC.

• 4591: VerifyQueue: re_notify other Worker when OnlySmallCycleTx received a large cycle tx (@eval-exec)
