Prepare the aggregator service

Hardware (Pre-alpha testnet)

For every rollup

• CPU per machine: 4-core CPU

• RAM per machine: 16GB RAM

Inventory

Download aggregator-config.tar

wget https://pre-alpha-miner-download.opside.network/aggregator_conf.tar
tar -xzvf aggregator_conf.tar

The .tar file includes:

• node.config.toml -- A TOML config file of the node image

• executor.config.json -- A JSON config file of the prover image (for executor)

• docker-compose.yml -- A docker-compose YAML file

• Database init SQL files -- Two .sql files

Download genesis.json

Select a rollup and download it's genesis.json here: Reference of selecting rollups

Your keystore

The keystore file of your aggregator account (responsible for sending proofs and collecting rewards)

• Download open source tool :

wget https://github.com/opside-protocol/opside-tool/releases/download/keystore/keystore-linux-x86_64

• How to use : https://github.com/opside-protocol/opside-tool#readme

Please put the above files under one directory

Download zkevm-node image

wget https://pre-alpha-miner-download.opside.network/zkevm-node.tar

Load the image

sudo docker load < zkevm-node.tar

Modify the config file

node.config.toml

In the graph "Stake IDE" , you have selected a rollup to stake, now you need to modify the node.config.toml with the information from the rollup.

You need to modify the [Etherman] , [Synchronizer] , [Aggregator] , [EthExManager].

You can find the informations of [Etherman] and [Synchronizer] here: Reference of selecting rollups

[Etherman]
