Run a Super World Computer node

This guide will help you get SWC node up and running.

Hardware requirements

Hardware requirements for SWC testnet nodes can vary depending on the type of node you plan to run. Archive nodes generally require significantly more resources than full nodes. Below are suggested minimum hardware requirements for each type of node.

• 8GB RAM

• 60 GB SSD (full node) or 200 GB SSD (archive node)

• Reasonably modern CPU

Software dependencies

Dependency	Version	Version Check Command
git	^2	git --version
go	^1.21	go version
make	^3	make --version
just	^1.34	just --version

Sync modes

For full nodes, the following configurations are available (explanation):

	op-node(CL)	op-geth(EL)
Full nodes EL snap sync	--syncmode=execution-layer (not default)	--syncmode=snap (default)
Full nodes EL full sync	--syncmode=execution-layer (not default)	--syncmode=full (not default)
Full nodes CL sync	--syncmode=consensus-layer (default)	--syncmode=full (not default)

For archive nodes, please add --gcmode=archive to op-geth.

Beta Testnet

Steps

1. Follow the following steps to build a node. The steps are basically the same as in Optimism's documentation, the only difference is that here we use the beta_testnet branch of both our optimism fork and our op-geth fork instead.

• 1.1 Build op-geth

  git clone -b beta_testnet https://github.com/ethstorage/op-geth.git
  pushd op-geth && make geth && popd

• 1.2 Build op-node

  git clone -b beta_testnet https://github.com/ethstorage/optimism.git
  pushd optimism && make op-node && popd

1. Setup op-geth:

   The default settings are for full nodes with snap sync. For configurations related to full sync or archive nodes, please refer to the Sync modes section.

       # assume optimism and op-geth repo are located at ./optimism and ./op-geth
   
       cd op-geth
       # prepare beta_testnet_genesis.json
       curl -LO https://raw.githubusercontent.com/ethstorage/pm/main/L2/assets/beta_testnet_genesis.json
       ./build/bin/geth init --datadir=datadir --state.scheme hash beta_testnet_genesis.json
   
       openssl rand -hex 32 > jwt.txt
   
       # We don't specify `--rollup.sequencerhttp` since it's for testing blob archiver only.
       # The rpc port is the default one: 8545.
       ./build/bin/geth   --datadir ./datadir   --http   --http.corsdomain="*"   --http.vhosts="*"   --http.addr=0.0.0.0   --http.api=web3,debug,eth,txpool,net,engine   --ws   --ws.addr=0.0.0.0   --ws.port=8546   --ws.origins="*"   --ws.api=debug,eth,txpool,net,engine  --networkid=3335   --authrpc.vhosts="*"   --authrpc.addr=0.0.0.0   --authrpc.port=8551   --authrpc.jwtsecret=./jwt.txt   --rollup.disabletxpoolgossip=true

2. Setup op-node:

   ⚠️ The op-node RPC should not be exposed publicly. If left exposed, it could accidentally expose admin controls to the public internet.

   Sync mode is set to --syncmode=execution-layer to enable snap sync.

       # assume optimism and op-geth repo are located at ./optimism and ./op-geth
       # copy jwt.txt from the op-geth directory above to optimism/op-node
       cp op-geth/jwt.txt optimism/op-node 
       cd optimism/op-node
   
       export L1_RPC_KIND=basic
       export L1_RPC_URL=http://88.99.30.186:8545
       export L1_BEACON_URL=http://88.99.30.186:3500
       # prepare beta_testnet_rollup.json
       curl -LO https://raw.githubusercontent.com/ethstorage/pm/main/L2/assets/beta_testnet_rollup.json
   
       mkdir safedb
       # Ensure to replace --p2p.static with the sequencer's address.
       # Note: p2p is enabled for unsafe block.
       ./bin/op-node   --l2=http://localhost:8551   --l2.jwt-secret=./jwt.txt   --verifier.l1-confs=4   --rollup.config=./beta_testnet_rollup.json  --rpc.port=8547   --p2p.static=/ip4/5.9.87.214/tcp/9003/p2p/16Uiu2HAm2w9ZsnP58zzGpPXGuCH8j6w9ecwA3uwXhkXxJniJEbUX --p2p.listen.ip=0.0.0.0 --p2p.listen.tcp=9003 --p2p.listen.udp=9003  --p2p.no-discovery --p2p.sync.onlyreqtostatic --rpc.enable-admin   --l1=$L1_RPC_URL   --l1.rpckind=$L1_RPC_KIND --l1.beacon=$L1_BEACON_URL --l1.beacon-archiver=http://65.108.236.27:9645 --safedb.path=safedb --syncmode=execution-layer

Devnet

Steps

1. Follow the following steps to build a node. The steps are basically the same as in Optimism's documentation, the only difference is that here we use the devnet branch of both our optimism fork and our op-geth fork instead.

• 1.1 Build op-geth

  git clone -b devnet https://github.com/ethstorage/op-geth.git
  pushd op-geth && make geth && popd

• 1.2 Build op-node

  git clone -b devnet https://github.com/ethstorage/optimism.git
  pushd optimism && make op-node && popd

1. Setup op-geth:

   The default settings are for full nodes with snap sync. For configurations related to full sync or archive nodes, please refer to the Sync modes section.

       # assume optimism and op-geth repo are located at ./optimism and ./op-geth

       build/bin/geth init --datadir=datadir devnet_genesis.json
   
       openssl rand -hex 32 > jwt.txt

       # assume optimism and op-geth repo are located at ./optimism and ./op-geth
       # copy jwt.txt from the op-geth directory above to optimism/op-node
       cp op-geth/jwt.txt optimism/op-node
       cd optimism/op-node
   
       # prepare devnet_rollup.json
