AIOZ Blockchain Explorer

Introduction

This project is written to track down most actions done on AIOZ blockchain: blocks, transactions, messages, events,... , enhanced by Cockroachdb.

How to start

There are 3 services need to be run:

1. Cockroachdb cluster (for dev, 1 node is enough)
2. GoB node, which is AIOZ node with GoB implemented inside, used to index data
3. Light Client Daemon (LCD) server: serve blockchain services like broadcasting transactions

Notes

Database

1. Mind the user, password (in case of security enabled), host, port, database name, schema,...
2. Check each table properties (index, primary key,...)

Replay blocks

There are 2 binary that runs block replay:

• aiozreplay: for aiozd in general
• replay: for explorer's needs

Other nodes

1. There are changes since v0.39.0 when you want to replay block:

• Previous version sets _state.LastHeightValidatorsChanged = 1
• If s.LastBlockHeight causes a valset change,
• We set s.LastHeightValidatorsChanged = s.LastBlockHeight + 1 + 1
• Extra +1 due to nextValSet delay.
• In replay/utils.go, set _state.LastHeightValidatorsChanged = rollbackBlock1.Header.Height + 1 + 1 for GoB replay
• In /cmd/aiozreplay/utils.go set _state.LastHeightValidatorsChanged = rollbackBlock1.Header.Height + 1 + 1 for aiozd replay
• Not yet testing on low block count with nothing changed in validators set
