ckb

This version is compatible with v0.25.0 and above. However, it is recommended to upgrade the node, since we will only release security patches based on the latest release.

See how to connect to various chains in Wiki.

Starting from v0.37.0, all the crates will be published to crates.io as well. See ckb in crates.io for details.

Breaking Changes

Database

⚠️ This new version will migrate the database on first launch. Please backup the data dir if you want to use old versions later.

⚠️ The migration takes about half an hour. The node denies all RPC requests during the migration.

Config file

There is a new config option db.options_file introduced in #2299. This option provides an options file to tune RocksDB for your workload and your system configuration. More details can be found in the official tuning guide. Remove or comment this option to use the default options file, which is the behavior in previous versions.

RPC

The RPC get_cells_by_lock_hash is deprecated and now it only returns errors (#2269).

There are 4 new RPC methods: ping_peers, get_transaction_proof, verify_transaction_proof, and clear_banned_addresses.

The subscribe RPC added a new topic new_transaction.

Downloads

* Windows support is experimental.

The .asc files are signatures. It is wise and more secure to check out for the files integrity.

Features

• #2270 rpc: Rework rpc doc (@doitian)

• #2299: Add a default RocksDB options file (@yangby-cryptape)

  The default options file limits the maximum memory usage.

  The mainnet has been online for a long time, and it is time to add a minimum workload proof to prevent possible node attacks during the initial synchronization.

• #2269: Redesign cell store (@zhangsoledad)

  Previous cell storage is inefficient. This PR proposal a new live cell storage schema, which optimized the resolve transaction bottleneck.

  Breaking Changes:

  • This PR will migrate the database.
  • The RPC get_cells_by_lock_hash is deprecated and now it only returns errors.

Features

• #2038 rpc: Re-organize RPC errors (@doitian)

  This is a breaking change: b:rpc

  This PR reworks on the RPC errors:

  • Use JSONRPC error code to differentiate different errors. Also prefix the error code in the message to be search engine friendly.
  • Make error message simple and easy to understand. The dump of the error is added as the data instead.
  • Avoid reusing the same error message for different reasons.

  Breaking Changes

  • The error object data field is always absent before, now it can be a string which contains the detailed error information.
  • The code in error object is always -3 for all the CKB internal errors, now it can have different values to differentiate different errors. Check the file rpc/src/error.rs.
  • The error messages have been updated to improve readability.

• #2049 rpc: Improve error messages from send transaction RPC (@doitian)

• #2178 rpc: Add generate_block RPC to IntegrationTest module (@quake)

  It allows user to generate block through RPC, it's a convenient feature for dApp integration test (like truncate RPC)

• #2188 rpc: Add sync state RPC (@driftluo)

  Wallet can fetch the best known block header the node gets from the P2P network.

• #2197: Should exit with error code when setup failed (@yangby-cryptape)

  Issue: if the config was malformed and an error was thrown in setup_app, the process wouldn't exit.

Improvements

• #2152: Change storage molecule table to struct (@quake)

  This is a breaking change: b:database

  Storage structs HeaderView, EpochExt and TransactionInfo are fixed size, we should use molecule struct instead of table, it reduces storage size and improves the performance a little bit.

Highlights in this release:

• #2067 is another improvement to the chain sync speed.
• #2145 limits the memory usage to make ckb friendly to devices with limited memory.

* Windows support is experimental.

Features

• #2067: Optimize scheduler (@driftluo)

  Problems with the current scheduler:

  1. The calculation is too frequent
  2. Inability to adapt to complex network environments.

  This PR implements an adaptive scheduler based on past data, removing most of the redundant calculations.

• #2145: Don't cache all block status in memory (@yangby-cryptape)

  When a node is start from number 0, it will sync all headers at first, then the block_status_map will be full quickly.
  Then, along with the block sync, all data in block_status_map will be removed.
  When the IBD is done, there will be nothing left in block_status_map.

  But when another new-started node try to sync data from this node, this node will fetch all block statuses from database and insert them into block_status_map without deletions. And full block status will store in memory until the node is shutdown.

  $ ckb peer-id gen --secret_path ./a.txt
  $ ckb peer-id from-secret --secret-path ./a.txt
  

• #2045: New subcommand replay (@zhangsoledad)

  The new subcommand can be used in both profiling and sanity check, such as verifiying the downloaded data directory archive.

• #2042: Return filename of jemalloc_profiling_dump (@keroro520)

• #2064: Add RPC truncate (@keroro520)

  For convenient to reproduce a specified environment when test, this PR adds RPC truncate(target_tip_hash) to roll-back the blockchain downto the target block.

• #2081: Update last_common_header only in find_blocks_to_fetch (@keroro520)

  peer.best_known_block refers to the best-known block we know this peer has announced; peer.last_common_header refers to the last block we both stored between local and peer. This PR proposes a new process to update the two fields.

• #2136: Add RPC clear_tx_pool to remove all the transactions in the tx-pool (@keroro520)

Bug Fixes

• #2101: Resolve an unexpected shutdown issue when we got a ProtoHandleBlock error in p2p (@quake)

• #2124: prepare_uncles_test failed on block_template update delayed (@zhangsoledad)

• #2140: Shrink state map (@zhangsoledad)

  Cause rust hash table capacity does not shrink automatically, we need explicit call shrink for predictable limit memory usage.

• #2109: Fix deadlock caused by conflicting lock order (@BurtonQin)

Improvements

• #2126: Remove fee estimator (@zhangsoledad)

  This estimate_fee_rate RPC is experimental, due to availability and performance issues, we decide to remove it.

• #2128: Try next listen address on parsing error (@doitian)

• #2107: Use generic key / value in template context (@quake)

  This PR changed TemplateContext key/value from fixed field to hashmap, it made the ckb-resource crate easier to use in 3rd party applications

• #2103: Use generic type in NetworkService (@quake)

  This PR changed NetworkService's exit_condvar to generic type and removed node_version from start fn, make it easier to use ckb-network crate as a lib

• #2096: Move network protocol related variables to SupportProtocols (@quake)

  To eliminate dependence of ckb-sync crate, this PR refactored network protocol related variables and move them to a new enum: SupportProtocols

ckb 0.34.0-pre (673fd25 2020-07-03)

This is an RC version to preview the changes in the next release.

Highlights in this release:

• #2067 is another improvement to the chain sync speed.
• #2145 limits the memory usage to make ckb friendly to devices with limited memory.

* Windows support is experimental.

Features

• #2067: Optimize scheduler (@driftluo)

  Problems with the current scheduler:

  1. The calculation is too frequent
  2. Inability to adapt to complex network environments.

  This PR implements an adaptive scheduler based on past data, removing most of the redundant calculations.

• #2145: Don't cache all block status in memory (@yangby-cryptape)

  When a node is start from number 0, it will sync all headers at first, then the block_status_map will be full quickly.
  Then, along with the block sync, all data in block_status_map will be removed.
  When the IBD is done, there will be nothing left in block_status_map.

  But when another new-started node try to sync data from this node, this node will fetch all block statuses from database and insert them into block_status_map without deletions. And full block status will store in memory until the node is shutdown.
