…
- **Apps pool**: the keyless account `ZBCAPPS`, the house of solo bets. It receives solo stakes and the 1 % rake of multiplayer games, and pays solo wins. See [[apps-pool|The apps pool]].
- **Archival node**: a registered node that also runs the archival service, the index behind search, statistics and the explorer. See [[explorer-and-archival-nodes|The explorer and archival nodes]].
+ - **Archive**: a planned design in which the decentralised storage keeps every snapshot from block 0, each snapshot held by a few registered nodes, so that the state at a past point can be rebuilt. See [[the-archive|The archive and reading the past]].
− - **Archive**: the copy of every snapshot from block 0 kept in the decentralised storage, each snapshot held by a few registered nodes, from which the state at a past point can be rebuilt. See [[the-archive|The archive and reading the past]].
- **Atomic unit**: the smallest amount of ZBC, 0.00000001 ZBC. One ZBC is 100,000,000 atomic units, and the chain counts every amount in them. See [[zbc-coin|The ZBC coin and its units]].
- **Attestation**: a registered node's signed statement of an event's value (AttestEvent). When two thirds of the active registry attest the same value, the event resolves. See [[triggers-and-attestations|Triggers and attestations]].
…
- **Block**: a signed bundle of transactions and receipts that extends the chain. One comes every 15 seconds. See [[blocks-and-time|Blocks and time]].
- **Block seed**: the random value each block carries, the output of a VRF over the previous seed under the producer's node key. It drives the next producer draw and the coinbase lottery. See [[block-seed|The block seed (VRF)]].
+ - **Bridge**: the way the wrapped coins ZBTC, ZETH, ZUSDC and ZUSDT are designed to be minted when two thirds of the registered nodes attest a deposit on the home chain, and burned on withdrawal. Its rules are part of the node from version 0.5.8; the bridge service is a planned design. See [[the-bridge|The bridge and wrapped coins]].
− - **Bridge**: the mechanism that mints the wrapped coins ZBTC, ZETH, ZUSDC and ZUSDT when two thirds of the registered nodes attest a deposit on the home chain, and burns them on withdrawal. See [[the-bridge|The bridge and wrapped coins]].
## C
- **Chain-bound signature**: a signature over a digest that includes the chain's genesis hash, so it is valid on one chain only. Every transaction is signed this way. See [[chain-bound-signatures|Chain-bound signatures]].
+ - **Channel app**: a two-player game played off-chain as signed vouchers and settled on chain in one transaction, which either player can override with a longer chain of signed moves within a 240-block challenge window. See [[channel-apps|Channel apps]].
− - **Channel app**: a two-player game played off-chain as signed vouchers and settled on chain in one transaction. See [[channel-apps|Channel apps]].
- **Checksum**: the last 3 bytes of an address, taken from SHA3-256 of the key and the prefix, which let wallets refuse a mistyped address. See [[accounts-and-addresses|Accounts and addresses]].
- **Claim**: the transaction (ClaimNodeRegistration) by which whoever holds a node key moves the seat's stake to an account it controls. A claim by anyone but the owner executes a week later, unless the owner removes the node first. See [[leaving-the-registry|Leaving the registry]].
…
- **Storage proof**: the hash a piece holder submits each epoch to show it still keeps a piece of a stored file; a fee-free duty. See [[storage-pool|The decentralised storage pool]].
- **Supply ceiling**: 33,333,333.33333333 ZBC per chain, counting the genesis credits and all coinbase to come. See [[supply-and-emission|Supply and emission]].
+ - **Survival deposit**: an optional amount in a transaction's survival field, at least 0.1 ZBC: the sender's own longevity deposit, which opens a longevity record keeping that transaction stored. See [[longevity|Paying to keep data (longevity)]].
− - **Survival deposit**: an optional amount in a transaction, at least 0.1 ZBC, that opens a longevity record keeping that transaction stored. See [[longevity|Paying to keep data (longevity)]].
- **Suspension**: a node is taken out of the draw at its 4th consecutive missed turn, and holds no lottery ticket while suspended. See [[missed-turns|Missed turns, suspension and expulsion]].
- **Swap offer**: an offer to exchange one asset for another, accepted whole by a single taker. See [[swap-offers|Swap offers]].
