#Web3 #Polkadot #BulletinChain
Pioneered by Polkadot: a new efficient data storage model for everyday Web3 applications
When it comes to storing and serving data, most Web3 apps still fall back on centralized Web2 servers. The missing piece has been a decentralized alternative that is actually suitable for everyday use. Bulletin Chain, pioneered by Polkadot, aims to solve this.
