v0.8.0

• Syncing and verifying blocks from Substrate-based networks like Polkadot. Supported networking protocols:
  • /<protocol-id>/sync/2 – sending and receiving block data
  • /<protocol-id>/transactions/1 – receiving and propagating users' transactions
  • /<protocol-id>/block-announces/1 – receiving and broadcasting advertisements that new block was created
  • /paritytech/grandpa/1 and /<genesis-hash>/grandpa/1 – sending and receiving grandpa votes, commits, catch up requests/responses and neighbor messages
• Compatibility with Polkadot JS apps
  • Implemented RPCs are account_nextIndex, author_hasKey, author_hasSessionKeys, author_insertKey, author_pendingExtrinsics, author_rotateKeys, author_submitAndWatchExtrinsic, author_submitExtrinsic,author_unwatchExtrinsic, chain_getBlock, chain_getBlockHash, chain_getFinalisedHead, chain_getFinalizedHead, chain_getHead, chain_getHeader, chain_getRuntimeVersion, chain_subscribeFinalizedHeads, chain_subscribeNewHead, chain_subscribeNewHeads, chain_unsubscribeFinalizedHeads, chain_unsubscribeNewHead, chain_unsubscribeNewHeads, childstate_getKeys, childstate_getKeysPaged, childstate_getStorage, childstate_getStorageAt, childstate_getStorageHash, childstate_getStorageHashAt, childstate_getStorageSize, childstate_getStorageSizeAt, internal_setLogLevel, payment_queryInfo, rpc_methods, state_getKeysPaged, state_getMetadata, state_getRuntimeVersion, state_getStorage, state_getStorageAt, state_queryStorage, state_queryStorageAt, state_subscribeRuntimeVersion, state_subscribeStorage, state_unsubscribeRuntimeVersion, state_unsubscribeStorage, system_accountNextIndex, system_chain, system_chainType, system_health, system_name, system_peers, system_properties, system_version
  • Decsriptions could be found here
• Polkadot telemetry support
  • Any KAGOME node is visible on https://telemetry.polkadot.io/ unless --no-telemetry flag is provided
• Interpreted and compiled WASM engines
  • Binaryen WASM interpreter is used as default WASM engine
  • WAVM is alternative WASM engine that uses LLVM to compile runtime code
• Prometheus metrics
  • Substrate-style metrics that provide essential information about node's execution
