Nervos CKB is a proof-of-work Layer-1 built on the Cell model — a generalised UTXO where every cell can hold state and code — secured by Eaglesong and governed in epochs, with a native state-rent/deposit system (NervosDAO) that pays interest for locking CKB. The network endpoint returns the chain state (tip block, epoch, block time, difficulty, hashrate); the blocks endpoint returns the most recent blocks with miner and reward; the block endpoint returns a single block by number or hash; the address endpoint returns an address's CKB balance, NervosDAO deposit and compensation, live-cell count and UDT token accounts; the transaction endpoint returns a transaction's block, fee and type. Live, no key, nothing stored. Distinct from the Bitcoin, Decred, Ergo and other on-chain APIs and from price feeds — this is Nervos CKB's own Cell-model, NervosDAO and PoW layer.",
