Definition
Polkadot connects independent blockchains — parachains — under shared security. A central relay chain handles consensus, while each parachain is free to specialise.
Key points
- Run your own chain under shared security
- On-chain governance
- Staking supported
Watch out for
- · The architecture is complex and hard for newcomers to follow
- · Projects must secure a parachain slot, which has a cost
