Antelope IBC Proof Docker

This includes everything needed to generate proofs for antelope chains and relay them to a client using websockets. It utilises docker compose to launch and manage mindreader, firehose, lightproof-db, ibc-server.

Scripts:

To install docker + docker compose plugin

./install-docker.sh

Start containers

./start.sh

Stop containers

./stop.sh

View running containers' logs

./logs.sh

dfuse logs

tail -f ./dfuse-data/dfuse.log.json

Delete all chain data (stop containers first)

sudo rm -rf dfuse-data/ lightproof-data/

---

Steps to run a proof server:

1 - Create a ".env" file (check .env.example) with the chain details, and desired host websocket port like so:

    NETWORK=ux-testnet
    API=https://testnet.uxnetwork.io
    CHAIN_ID=5002d6813ffe275d9471a7e3a301eab91c36e8017f9664b8431fbf0e812a0b04
    WS_PORT=7788

2 - To start from genesis: ./start.sh

To start from a snapshot:
   - Start indexing from before the previous power of 2's block number (see below)
   - Download and decompress a snapshot (V4/V6) and place it in the "snapshots" folder
   - Add the snapshot file name in the .env file like in .env.example  (SNAPSHOT=$NAME_OF_SNAPSHOT_FILE) 
   - If starting with an empty database, In ".env" set the START_BLOCK to a number above the snapshot's block number (1000 blocks above, to avoid firehose issues)
   - After starting the containers, you can remove/comment out the SNAPSHOT and START_BLOCK lines added to ".env" above, so they are not in effect on next restart.

Note on choosing snapshots:

To be able to generate proofs of actions occuring at a certain block, 
you need to start from a snapshot prior to the last power of two block height. 

For example, if current block height is at 190M blocks, the previous power of two 
would be block #134,217,728. You will need a snapshot before this block number, 
to be able to prove actions from block #134,217,728 and onwards.
