The validator setup and maintenance guide has moved to the Operator Guides book.
Validators secure the Nyx blockchain via Proof of Stake consensus. The Nyx blockchain records the ledger of
NYM transactions and executes the smart contracts for distributing
NYM rewards. The Nyx validators are run via the
nyxd binary (codebase), maintaining a CosmWasm- and IBC-enabled blockchain.
The blockchain plays a supporting but fundamental role in the mixnet: the
NYM token used to incentivise node operators is one of two native tokens of the chain, and the chain is where the Mixnet and Vesting smart contracts are deployed.
