  • 25 GB HDD
  • 1.4 GHz CPU
• Recommended
  • 2 GB RAM
  • 100 GB HDD
  • 2.0 GHz x2 CPU

NOTE: SSDs have limited TBW before non-catastrophic data errors. Running a full node requires a TB+ writes per day, causing rapid deterioration of SSDs over HDDs of comparable quality.

Operating System

• Linux/Windows/MacOS(x86)
• Recommended
  • Linux(x86_64)

Installation Steps

Prerequisite: go1.15+ required. ref

Prerequisite: git. ref

Optional requirement: GNU make. ref

Note: If running go the latest version (tested on 1.16.3), do export CGO_ENABLED="0" before make install

• Make the binary
  Might require you to run export CGO_ENABLED="0" before make.

make all

• Start the bridge

./build/..../persistenceBridge start {arguments}

When starting for first time --tmStart --ethStart needs to be always given, after that not adding it will start checking from last checked height + 1

path_to_chain_json json file for tendermint chain, same as the relayer format - {"key":"acc_0","chain-id":"test","rpc-addr":"http://192.168.1.4:26657","account-prefix":"cosmos","gas-adjustment":1.5,"gas-prices":"0.025stake","trusting-period":"336h"

--ethPrivateKey private key of account which will do txs to eth

• First time start persistenceBridge start chain.json "wage thunder live sense resemble foil apple course spin horse glass mansion midnight laundry acoustic rhythm loan scale talent push green direct brick please" --tmStart 1 --ethStart 4772131 --ethPrivateKey [ETH_ACC_PRIVATE_KEY]

Note: Remove --tmStart --ethStart when starting next time
