indexers

Build Status ISC License GoDoc

Package indexers implements optional block chain indexes.

These indexes are typically used to enhance the amount of information available via an RPC interface.

Supported Indexers

  • Transaction-by-hash (txbyhashidx) Index
    • Creates a mapping from the hash of each transaction to the block that contains it along with its offset and length within the serialized block
  • Transaction-by-address (txbyaddridx) Index
    • Creates a mapping from every address to all transactions which either credit or debit the address
    • Requires the transaction-by-hash index

Installation

$ go get -u github.com/daglabs/btcd/blockchain/indexers
