Introduction to
What is?
a network that connects Blockchains is Attempting to solve problems:
1. Interoperability 2. Scalability 3. Shared Security
How does work ?
network • Validators • Nominators • Collators • Fishermen
network • Validators - Secure the relay chain by staking
DOTs, validating proofs from collators and participating in consensus with other validators
network • Nominators - Secure the relay chain by selecting
good validators and staking DOTs
network • Collators - Maintain parachains by collecting parachain transactions
from users and producing state transition proof for validators.
network • Fishermen - Final security frontier, they monitor the
network and prove bad behaviour to validators
