Validation Ledger & Transaction Store

To generate xPOPs

Watcher that connects to multiple nodes & listens for validation messages, closed ledgers & transactions, and stores all of it in an organised file system data structure for xPOP generation.

Based on the work by @RichardAH: https://github.com/RichardAH/xpop-generator

Output

Folder

This tool creates a folder structore in the ./store directory, where it creates sub-directories like this:

store / {networkid} / {ledgerno(0, -6)} / {ledgerno(-6, -3)} / {ledgerno(-3)} /

So e.g. for NetworkId 21338, ledger index 82906790, the path would be:

store/0/82/906/790

This way entire chunks of stored ledger scan be easily fetched or pruned by removing a directory recursively.

Folder contents

Every folder will contain the following files:

• ledger_binary_transactions.json with the binary info for a ledger command, including transactions. The transactions contain the meta, tx_blob and a computed tx_id
• ledger_info.json with the regular ledger command output
• vl.json with the UNL validator list (signature checked)
• validation_{signing pubkey}.json, e.g. validation_n9McDrz9tPujrQK3vMXJXzuEJv1B8UG3opfZEsFA8t6QxdZh1H6m.json
• tx_{tx hash}.json, e.g. tx_FFDEADBEEF64F423CB4B317370F9B40645BA9D5646B47837FDC74B8DCAFEBABE.json
• (Optional, if all info was present) xpop_{tx hash}.json
