Pros
  • Reusable and custom modules support tailored blockchain logic
  • Native IBC enables cross-chain data and asset transfers
  • Enterprise modules support permissioned and consortium networks
  • 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-hosted deployment puts node operations on your team
  • Custom chains require blockchain engineering and module development
  • Production use requires configuring and operating a network
  • 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!.
