rpcProperties

get rpcProperties(): RpcPropertes

- Defined in packages/rpc/src/Base/index.ts:520
Returns RpcPropertes

Methods

getForkBlock

getForkBlock(blockHash: Hash256, verbosity?: 2n | "0x2"): Promise<BlockView | null>
getForkBlock(blockHash: Hash256, verbosity: 0n | "0x0"): Promise<SerializedBlock | null>

- Defined in packages/rpc/src/Base/index.ts:466
method

getForkBlock

Parameters
- blockHash: Hash256
  
  the fork block hash.
- Optional verbosity: 2n | "0x2"
  
  result format which allows 0 and 2. (Optional, the default is 2.)
Returns Promise<BlockView | null>

a fork block or null. When the RPC returns a block, the block hash must equal to the parameter blockHash. Please note that due to the technical nature of the peer to peer sync, the RPC may return null or a fork block result on different nodes with same block_hash even they are fully synced to the canonical chain. And because of chain reorganization, for the same block_hash, the RPC may sometimes return null and sometimes return the fork block. When verbosity is 2, it returns a JSON object as the result. See BlockView for the schema. When verbosity is 0, it returns a 0x-prefixed hex string as the result. The string encodes the block serialized by molecule using schema table Block.
- Defined in packages/rpc/src/Base/index.ts:470
Parameters
- blockHash: Hash256
- verbosity: 0n | "0x0"
Returns Promise<SerializedBlock | null>
