Module bdk::blockchain

Blockchain backends

This module provides the implementation of a few commonly-used backends like Electrum, Esplora and Compact Filters/Neutrino, along with a generalized trait Blockchain that can be implemented to build customized backends.

  Trait that defines the actions that must be supported by a blockchain backend
• BlockchainFactory
  Trait for a factory of blockchains that share the underlying connection or configuration
• ConfigurableBlockchain
  Trait for Blockchain types that can be created given a configuration
• GetBlockHash
  Trait for getting block hash by block height
• GetHeight
  Trait for getting the current height of the blockchain.
• GetTx
  Trait for getting a transaction by txid
• Progress
  Trait for types that can receive and process progress updates during WalletSync::wallet_sync and WalletSync::wallet_setup
