Refers to an address (starts with
kizn_ which are interchangeable) that you control the private keys of. An address is a reinterpretation of the 256-bit public key using BASE32 encoding and a checksum. Previously supported
kizn- prefixes are deprecated.
A newly downloaded block to the node which enters into the voting process.
ad hoc accounts¶
Accounts not derived from a private seed which can be held in the node wallet through the wallet ID. These accounts are only recommended for use with advanced systems.
A repeating half-second cycle on the node during which votes are collected for active transactions in attempt to reach quorum.
A single KIZUNANO COIN transaction. All new transactions (e.g. sends, receives, representative changes, etc) on KIZUNANO COIN Protocol are communicated via state blocks (since node V11). The account's entire state, including the balance after each transaction, is recorded in each block. Transaction amounts are interpreted as the difference in balance between consecutive blocks. Before V11, each transaction type (open, send, receive, change) had its own legacy block type.
A 64 character, uppercase hexadecimal string (0-9A-F) value representing a unique block on an account.
A local integer value that represents the order of a block in an account chain. For example, the 15th block in an account would have a block height of 15. Related to (but different from) confirmation height.
The Block Lattice is a data-structure in which individual accounts control their own blockchain. This allows transactions to be added quickly without conflict and sent to the network for confirmation.
Blocks Per Second (BPS)¶
The transmission rate of unconfirmed blocks (transactions) on the network.
A sub-network established between peers via Transmission Control Protocol (TCP) for managing bulk transmission of blocks. This is used on initial bootstrapping of peers and when out-of-sync peers attempt to fill large gaps in their ledgers. This is available within all KIZUNANO COIN networks (main, beta and test networks).
During initial sync, the kizunano_node requests old transactions to independently verify and populate its local ledger database. Bootstrapping will also occur when the kizunano_node becomes out of sync with the network.
20,000,000,000 KIZN. This is the supply that resulted after burns were made from the genesis account, landing account and faucet account, following original distribution. Actual circulating supply is lower due to lost keys and sends to burn accounts. The original supply minus any amounts sent to the burn account can be found using the available_supply RPC.
When a specific node marks a confirmed transaction as locally irreversible by setting the account's confirmation height (in the node database) to the now higher block height of the confirmed transaction. Cementing is a node-level operation.
When a block (transaction) gathers enough votes from the network to pass quorum. Note that confirmed sends are irreversible (i.e. fully-settled), but the receiver must publish a corresponding receive block before they will be able to spend the pending funds. Confirmation is a network-level decision.
Confirmations Per Second (CPS)¶
The most recent block added to the account chain. Also called the head block. Can be either confirmed or unconfirmed.
Blocks on an account chain before the first v1 block (which is often the v1 epoch block but can be other types). The first v1 block and all subsequent blocks are stateful blocks.
A sub-network established between peers via Transmission Control Protocol (TCP) for communicating newly published blocks, votes and other non-bootstrap related traffic. This is available within all KIZUNANO COIN networks (main, beta and test networks). In versions prior to V19, this was done via User Datagram Protocol (UDP). UDP was retained as a fallback for peer connection for versions 19 and 20. As of V21, use of UDP is deprecated.
The version used to identify a unique release build of the node. Each node version is tied to a single protocol version, but they are updated independently.
online voting weight¶
Also called online stake, it is a trended value. The node samples online representative weights every 5 minutes across a rolling 2 week period. The online voting weight value is the median of those samples.
Nodes connected over the public internet to share KIZUNANO COIN network data.
A transaction state where a block sending funds was published and confirmed by the network, but a matching block receiving those funds has not yet been confirmed.
Open Representative Voting (ORV)¶
A consensus mechanism unique to KIZUNANO COIN which involves accounts delegating their balance as voting weight to Representatives. The Representatives vote themselves on the validity of transactions published to the network using the voting weight delegated to them. These votes are shared with their directly connected peers and they also rebroadcast votes seen from Principal Representatives. Votes are tallied and once quorum is reached on a published block, it is considered confirmed by the network.
A Proof-of-Work is a piece of data which satisfies certain requirements and is difficult (costly, time-consuming) to produce, but easy for others to verify. In some systems this data is a central part of the security model used to protect against double-spends and other types of attacks, but with KIZUNANO COIN it is only used to increase economic costs of spamming the network.
When the delta between the two successive blocks of a root is > 50% of the online voting weight.
A KIZUNANO COIN account with >= 0.1% of the online voting weight delegated to it. When configured on a node which is voting, the votes it produces will be rebroadcasted by other nodes to who receive them, helping the network reach consensus more quickly.
The version used to identify the set of protocol rules nodes are required to follow in order to properly communicate with peers. Nodes running older protocol versions are periodically de-peered on the network to keep communication efficient and inactive releases for the latest versions allowed to peer with one another.
A KIZUNANO COIN account with > 0 voting weight, but < 0.1% of the online voting weight, delegated to it. Unlike Principal Representatives, when configured on a node which is voting, the votes it produces and sends to directly connected peers won't be rebroadcasted by those peers.
The account if the block is the first block on the account, otherwise it is the previous hash included in the block.
A 256-bit random value usually represented to the user as a 64 character hexidecimal (0-9 and A-F) value. Private keys are derived from a seed.
Transactions Per Second (TPS)¶
Historically, TPS was a per-node measurement that represented a node's perception of the rate of transactions on the network (BPS). This measurement was found to be inaccurate due to peering and propagation differences between nodes, so CPS is now the preferred term for describing overall KIZUNANO COIN network scalability. It's also important to note that while KIZUNANO COIN sends do not require a corresponding receive to be confirmed, a receive block must be confirmed before received funds can be sent again (see pending).
Blocks (transactions) that have been downloaded but not yet processed by KIZUNANO COIN node. The node software downloads all bocks from other nodes as unchecked, processes them and adds to block count, confirms the frontier blocks for each account, and then marks them as cemented.
An account address that does not have a first block on it (which must be a block to receive KIZUNANO COIN sent from another account, cannot be a block only changing the Representative).
Allows representatives to only include the hash of a block in each vote to save bandwidth. Before vote-by-hash was activated the entire block contents were required.
Each node configured with a Representative votes on every block by appending their Representative signature and a sequence number to the hash. These will be sent out to directly connected peers and if the vote originates from a Principal Representative, it will subsequently be rebroadcasted by nodes to their peers.
The amount of weight delegated to a Representative.
A wallet is an organizational object in a kizunano_node that holds a single seed from which multiple accounts are deterministically derived via a 32-bit unsigned integer index starting at 0. Private keys are derived from the seed and index as follows: (
|| means concatenation;
blake2b is a highly optimized cryptographic hash function)
A 256-bit random value name/identifier for a specific wallet in the local kizunano_node database. The WALLET_ID is not stored anywhere in the network and is only used in the local kizunano_node. Even though a WALLET_ID looks identical to a seed, do not confuse the WALLET_ID with a seed; funds cannot be restored with a WALLET_ID. Do not backup the WALLET_ID as a means to backup funds.
Node peers which are configured to generate work for transactions at the originating nodes request.
