DogeWalker

DogeWalker is a Go library that walks the Dogecoin blockchain from a specified starting block, fetching and decoding each block and allowing you to process it.

It also notifies you when a "reorganisation" is encountered on-chain, meaning one or more blocks need to be backed-out and their effect undone.

Reorgs can be handled effectively by recording the block-height in your database with each change caused by a block. When a reorg occurs, back out all changes tagged with a greater block-height than the LastValidHeight given in the undo message.

Reorg information also includes all the block ids being undone, and if requested in WalkerOptions, all transactions in those blocks.
