Edge Computing Provider(ECP)

ECP (Edge Computing Provider) specializes in processing data at the source of data generation, using minimal latency setups ideal for real-time applications. This provider handles specific, localized tasks directly on devices at the network’s edge, such as IoT devices.

At the current stage, ECP supports the generation of ZK-Snark proof of Filecoin network, and more ZK proof types will be gradually supported, such as Aleo, Scroll, starkNet, etc

Prerequisites

  • Need to map the ECP service port of the intranet to the public network, the default port is9085:
 <Intranet_IP>:<9085> --> <Public_IP>:<PORT>
  • Running the setup.sh
curl -fsSL https://raw.githubusercontent.com/swanchain/go-computing-provider/releases/ubi/setup.sh | bash
  • Download the v28 parameters for ZK-FIL task:
# At least 200G storage is needed
export PARENT_PATH="<V28_PARAMS_PATH>"

# 512MiB parameters
curl -fsSL https://raw.githubusercontent.com/swanchain/go-computing-provider/releases/ubi/fetch-param-512.sh | bash

# 32GiB parameters
curl -fsSL https://raw.githubusercontent.com/swanchain/go-computing-provider/releases/ubi/fetch-param-32.sh | bash

Install ECP and Init CP Account

  • Download computing-provider
wget https://github.com/swanchain/go-computing-provider/releases/download/v0.5.0/computing-provider
  • Initialize ECP repo
 ./computing-provider init --multi-address=/ip4/<YOUR_PUBLIC_IP>/tcp/<YOUR_PORT> --node-name=<YOUR_NODE_NAME>
  • Generate a new wallet address and deposit the SWAN-ETH, refer here:
./computing-provider wallet new

Output:

 0x9024a875f44172591373b92...31d67AcCEa
  • [OPTIONAL] You can also import your own wallet by private key
./computing-provider wallet import private.key

Note:

  1. By default, the CP's repo is ~/.swan/computing, you can configure it by export CP_PATH="<YOUR_CP_PATH>"

  2. private.key is a file that contains the private key

  • Initialize ECP Account
./computing-provider account create \
                    --ownerAddress <YOUR_OWNER_ADDRESS> \
                    --workerAddress <YOUR_WORKER_ADDRESS> \
                    --beneficiaryAddress <YOUR_BENEFICIAERY_ADDRESS>  \
                    --task-types 1,2,4

Note: --task-types: Supports 4 task types (1: Fil-C2-512M, 2: Aleo, 3: AI, 4: Fil-C2-32G), separated by commas. For ECP, it needs to be set to 1,2,4.

  • Collateral Swan-ETH for ECP
./computing-provider collateral add --ecp --from <YOUR_WALLET_ADDRESS>  <AMOUNT>

Note: Currently one zk-task requires 0.0005 Swan-ETH.

Start ECP service

#!/bin/bash
export FIL_PROOFS_PARAMETER_CACHE=$PARENT_PATH
export RUST_GPU_TOOLS_CUSTOM_GPU="GeForce RTX 4090:16384"   
        
nohup ./computing-provider ubi daemon >> cp.log 2>&1 &

Note:

  • <FIL_PROOFS_PARAMETER_CACHE> is your parameters directory,
  • RUST_GPU_TOOLS_CUSTOM_GPU is your GPU model and cores, you should update it to your own GPU model. More examples can be found here
  • <YOUR_PUBLIC_IP>, <YOUR_PORT> are your public IP and port ,
  • <YOUR_NODE_NAME> is your CP name which will show in the dashboard, If not specified, the default is hostname.
