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.

The version v0.100.0 will bring incompatible changes for the next hard fork but it will not activate the hard fork for testnet and mainnet. So it is compatible with the current testnet and mainnet.

• The block header as a new field extra_hash, which replaced uncles_hash.
• The block has a new field extension but no blocks may set it before the hard fork activation.
• The field hash_type has a new allowed value "data1" but it is invalid before the hard fork activation.
• The default value of the parameter OutputsValidator in the JSON RPC send_transaction is well_known_scripts_only now. See #2821 for details.

Downloads

* Windows support is experimental.

** The binaries require following CPU instructions: call (MODE64), cmovbe (CMOV), xorps (SSE1), movq (SSE2)

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

This version contains the fork features in ckb2021 which are disabled in testnet and mainnet.

• The dev chain sets permanent_difficulty_in_dummy by default and will generate a random genesis hash by default. See #2503 for details.

Features

• #2503: Customize chain spec for dev chains and update few preset params (@yangby-cryptape)

  • Set permanent_difficulty_in_dummy to true as default for dev chains.
  • Allow users to create different dev chains by customizing genesis message.
    And they could also create same chain in different directories or machines by setting a same genesis message.
  • Allow users to create different dev chains by customizing genesis timestamp.
    If no timestamp is provided, use current timestamp.
  • Display genesis hash after CKB direcotry created.

• #2569: Add rpc generate_block_with_template to IntegrationTest rpc module (@quake)

  This PR adds generate_block_with_template rpc, so that dApps can get block template from get_block_template rpc, and then add or remove tx / proposal / uncle data in block template, and finally submit it via this rpc to control the newly generated block data.

Bug Fixes

• #2556: Resolve peer store dump issue (@quake)

Improvements

• #2525: Manually trigger compaction after freeze (@zhangsoledad)

  • Drawbacks: Even we use DeleteRange apply to delete the range of keys, seems Rocksdb still hasn't implemented the feature of using seek() to skip until the end of range delete end yet.
    Rocksdb iter seek slows down dramatically when there are many deletes.
  • Workaround: Manually call CompactRange() for the range to delete, this approach can solve the problem.

RPC Deprecation

Pay attention that following RPC methods will be removed from v0.40.0:

• The method get_cells_by_lock_hash in the module Chain.
• The whole module Indexer.

The following methods will be disabled by default from v0.40.0 and will be removed from v0.41.0:

• The method get_cellbase_output_capacity_details in the module Chain.
• The method get_peers_state in the module Stats.
• The methods _compute_transaction_hash, _compute_script_hash and estimate_fee_rate in the module Experiment.

Config Changes

Because of deleted RPC methods, following keys must be deleted from the existing config file ckb.toml:

• Indexer is no longer a valid RPC module in [rpc] modules.
• The whole section [indexer] is removed.

  Freezer is disabled by default. It has some performance bottlenecks that we are fixing.
