Learn how to build fast, scalable, and secure dApps on FLAG Blockchain. FLAG is EVM

What is FLAG?

FLAG is a fast, scalable, and secure layer-1 blockchain gaming platform built on an aBFT consensus protocol.
FLAG is:
  • permission-less
  • decentralized
  • open-source
PolyBFT, its revolutionary consensus mechanism, allows FLAG to be much faster and cheaper than previous technologies, yet extremely secure.

Key features

Speed

FLAG achieves transactions finality in 1 second on average.

Scalability

FLAG can process thousands of transactions per second and can scale to hundreds of nodes.

Security

PolyBFT provides institutional-grade security to distributed networks. FLAG offers absolute finality, which means that transactions can never be reverted like in networks with probabilistic finality. FLAG is also leaderless. By removing leaders, security doesn’t rely on a small set of actors.

Smart contract support

FLAG is fully compatible with Ethereum. Developers can create and deploy smart contracts as they would on Ethereum.

Consensus-as-a-service

PolyBFT can be used to create any kind of private and public distributed ledger, using EVM or Cosmos SDK.
