Changes since v0.15.0

Features

• #1119: Remove rules of special reserve blocks (@doitian)

  This is a breaking change: b:consensus, b:database

  For block 1~11, the reward target is genesis block. Yes the reward for genesis is issued multiple times.

  Genesis block must have the lock serialized in the cellbase witness, which is set to bootstrap_lock.

• #1125: Add get_header and get_header_by_number RPC methods (@TheWaWaR)

  Add two RPC methods

  • get_header
  • get_header_by_number

  Usage scenario:

  • ckb-cli get genesis block header to distinguish testnet and mainnet
  • SPV client just get headers to verify a transaction

• #1124: Allow TransactionScriptsVerifier set custom debugger printer (@TheWaWaR)

  Current Debugger only log the output and can not detected by outside.

  Here we pass a callback to process debug output.

• #1094: Secondary miner issurance, split DAO as a separate contract (@xxuejie)

  This is a breaking change: b:consensus, b:database

• #1137: Remove output for bootstrap lock in genesis block (@doitian)

  The lock has already been written into the cellbase witness in the genesis block.

• #1138: --ba-data requires --ba-arg or --ba-code-hash (@doitian)

Bug Fixes

• #1092: Random failure caused by dirty exit in RPC test (@doitian)

  Close the server before exit RPC test.

• #1097: IBD should remain false once returned false (@quake)

  This PR is trying to resolve IBD peer timeout slow switching issue for some special case, e.x. node resume after hibernation, it's a performance optimization also.

• #1100: Resolve compact block switch fork issue (@quake)

• #1101: Fix debug log state error (@driftluo)

  fix debug log state error

• #1103: Fix sync logic (@driftluo)

  1. fix protect node count
  2. fix header sync eviction condition

• #1108: Potential error in alert version compare (@jjyr)

  As @keroro520 mentioned, there is a potential bug in case like: "0.10.0" < "0.9.10"

• #1117: RPC test (@jjyr)

• #1127: Process orphan blocks when their parents were relayed (@keroro520)

  • test: Add an integration-test test_relay_parent_of_orphan_block
  • feat: Move orphan_block_pool into SyncSharedState
  • fix: Process orphan blocks when their parents were relayed. If relayer does not process the orphan_block_pool when inserting a new relaying block, it may leave some orphan blocks that be unable to re-process any further. This change makes synchronizer and relayer share the same one implementation of insert_new_block, so the above bug been fixed.

• #1109: Mark failed dialing as feeler (@jjyr)

• #1134: Integration test broken by #1094 (@xxuejie)

• #1135: Total difficulty comparison should include hash (@quake)

  resolve similar bug as #1100 and refactor the previous fix to method.

• #1139: Resolve fresh proposal txs checking bug (@quake)

• #1144: Prof tps exclude cellbase (@jjyr)

• #1150: Correct block number from tx_pool_excutor (@keroro520)

  • fix: The block number of the coming block should be tip_number + 1

  ---

  NOTE: This is a breaking change

• #1196: Reserved only do nothing except for connect all reserved peers (@driftluo)

  Reserved only do nothing except for connect all reserved peers

Improvements

• #1072: Reveal network errors and involver handle it (@keroro520)

  • feat: Reveal network errors. Currently, when CKBProtocolContext receives an error from p2p, it only logs the error and doesn't return to the caller. I change to CKBProtocolContext return the error to the caller, and caller handles it.

  • perf: Short-circuiting break if occurs network error, Synchronizer responses Blocks and Transactions. This is the original intention of this PR. To achieve it, I have to make CKBProtocolContext reveals the network errors, which introduces most of the change code.

• #1073: Define a general Filter struct (@keroro520)

• #1098: Avoid re-requesting blocks in orphan pool (@keroro520)

• #1032 storage: Use flatbuffer instead of bincode in storage (@yangby-cryptape)

  This is a breaking change: b:database

• #1126: Skip stored block processing (@quake)

Misc

• #1081: More tests on ckb utils (@jjyr)
• #1106: Add alerts example in RPC doc (@jjyr)

  2. block reward finalized after proposal window close.
  3. enforce one-input one-output one-witness on cellbase.

• #1054: Replace system cell (@driftluo, @jjyr)

  See feat: use recoverable signature to reduce tx size by jjyr · Pull Request #15 · nervosnetwork/ckb-system-scripts

  BREAKING CHANGE: It changes the default secp256k1 script, which now uses recoverable signature.

Changes since v0.13.0

Features

• #913: New verification model (@xxuejie)

  This is a breaking change: b:consensus, b:database, b:p2p, b:rpc

  Based on feedbacks gathered earlier, we are revising our verification
  model with the following changes:

  • When validating a transaction, CKB will grab all lock scripts from
    all inputs, and group them based on lock script hash. The script in
    each group will only be run once. The lock script itself will have
    to do the validation task for all inputs in the same group
  • CKB will also grab all type scripts from inputs and outputs(notice
    different from previous version, the type scripts in inputs are
    included here as well), and group them based on type script hash as
    well. Each type script in each group will also be run once. The type
    script itself needs to handle the validation task within the group
  • Syscalls are also revised to allow fetching all the
    inputs/outputs/witnesses within a single group.
  • Input args is removed since the functionality can be replicated elsewhere

• #908: Peers handle disconnect (@keroro520)

• #891: Secp256k1 multisig (@jjyr)

• #845: Limit TXO set memory usage (@yangby-cryptape)

  This is a breaking change: b:database

• #874: Revise uncle rule (@zhangsoledad)

  This is a breaking change: b:consensus, b:database

  1. get rid uncle age limit
  2. try include disconnected block as uncle

• #920: Tweak consensus params (@zhangsoledad)

  This is a breaking change: b:consensus

  tweak block_cycles_limit and min_block_interval

• #897: Wrap the log macros to fix ill formed macros (@yangby-cryptape)

  And, we have to update the log filters, add prefix ckb- for all our crates.

• #919: Synchronizer and relayer share BlocksInflight (@keroro520)

• #924: Add a transaction error InsufficientCellCapacity (@yangby-cryptape)

• #926: Make a better error message for miner when method not found (@yangby-cryptape)

• #961: Display miner worker status (@quake)

  BREAKCHANGE: config file ckb-miner.toml changed

• #1001: ckb init supports setting block assembler (@doitian)

  • ckb init accepts options --ba-code-hash and --ba-arg (which can
    repeat multiple times) to set block assembler.
  • ckb cli secp256k1-lock adds an output format cmd to prints the
    command line options for ckb init to set block assembler.

  The two commands can combine into one to init the directory with a secp256k1 compressed pub key:

    ckb init $(ckb cli secp256k1-lock <pubkey> --format cmd)
  

• #996: Tweak consensus parameters (@doitian)

  • Change target epoch duration to 4 hours
  • Reduce epoch reward to 1/4
  • Increase secondary epoch reward to 600,000 bytes

Bug Fixes

• #878: Calculate the current median time from tip (@keroro520)

  This is a breaking change: b:consensus

  Original implementation use [Tip-BlockMedianCount .. Tip-1] to calculate the current block median time. According to the notion of BlockMedianTime in bip-0113 , here change to use [Tip-BlockMedianCount+1 .. Tip] instead.
