A node for a cross-chain bridge between Ethereum and Bitcoin implemented in the Lightning protocol,you can learn more here zkbtc

To gather blockchain data, the following blockchain node JSON RPC methods must be supported

1. bitcoin full node Bitcoin,we recommend using node version 28.1
2. ethereum beacon chain full node Prysm,we recommend using node version v6.0.0
3. ethereum execution chain full node Ethereum,we recommend using node version v1.15.10

1. Daemon just gather data, ordinary servers are sufficient, there are no special requirements
2. The generator requires significant CPU and memory resources to create zero-knowledge proofs, along with additional disk space to store the zero-knowledge parameter file ,the following are the machine parameters we tested

Minimum machine requirements,other tested machines example

CPU   : 24 cores
Memory: 64GB
Disk  : 250GB

1.Build setup program

git clone https://github.com/lightec-xyz/daemon
cd  daemon/cmd/setup && go build

2.Download aztecSrs to generate zero-knowledge parameter file

3.Run setup program

./setup  --datadir <circuitDir> --srsdir <srsDir> run --group all --chainId 17000 --zkbtcBridgeAddr 0x49793ff075b696e6bef1b85e4e85fe669041b312 --icpPublickey 023f203422be55a3576f46dc6770bdc7865a126381c1963a2d82b49f4158409a2e

Build zkbtc node daemon ( gather relevant transaction data from the blockchain)

git clone https://github.com/lightec-xyz/daemon
cd  daemon/cmd/node && go build

Build zkbtc daemon generator (the program that generates zero-knowledge proofs)

git clone https://github.com/lightec-xyz/daemon
cd  daemon/cmd/generator && go build

The daemon default storage location is: ~/.daemon,run zkbtc daemon ,you can find other field detailed explanations here.

// config.json
{
    "btcUrl": "http://127.0.0.1:8332",
    "ethUrl": "http://127.0.0.1:8545",
    "beaconUrl": "http://127.0.0.1:30814",
}

// run node
./node --config ./config.json run

The generator default storage location is: ~/.generator ,run zkbtc generator,config template here.

//config.json
{
    "url": "http://127.0.0.1:8970",
    "maxNums": 1,
    "ethSetupDir": "<circuitSetupPath>",
    "btcSetupDir": "<circuitSetupPath>",
}

// run generator
./generator --config ./config.json run
