EthStorage is a modular and decentralized storage Layer 2 that offers programmable key-value storage powered by DA. It enables long-term DA solutions for Rollups and opens up new possibilities for fully on-chain applications like games, social networks, AI, etc.
The main motivation behind EthStorage is to provide a long-term DA based on Ethereum.
EIP-4844 introduces data blobs that enhance the throughput and efficiency of L2 scaling solutions like rollups. However, the blob data is only available temporarily, meaning it will be discarded in a few weeks. This has generated a significant impact: the inability of L2 to unconditionally derive the latest state from L1. If a certain piece of data can no longer be retrieved from L1, a rollup may not be possible to sync the chain.
With EthStorage as a long-term DA solution, L2s can derive from their DA layer (Ethereum DA, Celestia, EigenDA, etc. + EthStorage) any time they want.
EthStorage also opens up new possibilities for fully on-chain applications like games, social networks, AI, etc.
Install all the Node.js dependencies:
pnpm fetch -r
pnpm install -r
Run the local Postgres and Redis containers:
docker compose -f docker-compose.local.yml up -d postgres redis
pnpm dev
Lastly, create the database schema:
pnpm db:generate
- build
sudo pnpm build
- run pm2
pm2 start pm2.config.js
- check pm2 progress
pm2 ls
- If the code has been updated, rerun
sudo pnpm buildand then restart the PM2 process. Currently, there are some minor issues with directly restarting, so you need to stop the process (either3000 or 3001) first and then restart it.
pm2 reload blobscan-api
// or
pm2 reload blobscan-web
