Our review
Pros
  • EVM-equivalent execution supports standard Solidity contracts and Ethereum tooling.
  • Configurable settlement, data availability, fees, gas tokens and fault proofs.
  • Self-managed or managed operations with compliance controls for permissioned chains.
  • Customize chain logic with reusable runtime pallets.
  • Choose among configurable PoW, Aura, BABE, and GRANDPA consensus.
  • Support forkless runtime upgrades with on-chain WebAssembly.
Cons
  • Self-managed deployments put cloud and VPC operations on your team.
  • Fully managed infrastructure pricing is quote-based.
  • Its focus is Ethereum-compatible optimistic rollups, not general blockchain designs.
  • Requires a self-hosted deployment.
  • Targets blockchain developers building their own networks.
  • Smart-contract end-to-end testing is local-node based and uses ink!.
