- Fee¶
The amount of tokens an address pays for the transactions it sends to the blockchain
- Consensus¶
Algorithm of coordination of information recorded in the blockchain between its participants
- License¶
A document granting the right to use the Waves Enterprise blockchain platform
- Leasing¶
Leasing of tokens on a participant’s balance to other participants. Leasing is used to create a generating balance from the participant taking tokens on lease, as well as to increase the probability of the participant’s selection by the miner of the next round when using the LPoS consensus algorithm
- Miner¶
Node, having the right to create new blockchain blocks
- Mining¶
The process of creating new blockchain blocks
- Migration¶
The process of changing key blockchain parameters
- Microblock¶
A set of transactions applied to a blockchain state. The number of transactions in a microblock is limited to 500 units. Microblocks form a network block. Microblocks are generated only under load: if there are no transactions, only blocks are released.
- Node¶
A network participant’s computer with the Waves Enterprise blockchain platform software installed and a network address assigned
- Node update¶
Updating the Waves Enterprise blockchain platform software installed on a network member’s computer
- Image¶
A smart contract template that contains its code and is used to create a Docker container in which the smart contract is executed
- Rollback¶
Sending an already created block for re-mining due to failures occurring on blockchain nodes
- Peer¶
Node network address
- Transaction signing¶
Adding to the body of the transaction the public key of its creator, used to confirm the integrity of the transaction in the blockchain
- Private network, sidechain¶
A blockchain network separate from Waves Enterprise Mainnet and with its own registered participants
- Private key¶
A string combination of characters for transactional signing and token access, to which only its owner has access. The private key is inextricably linked to the public key
- Transaction broadcasting¶
Writing a transaction to a blockchain block during a mining round
- Public network¶
A large blockchain network where each participant is known and registered in advance (e.g., Waves Enterprise Mainnet)
- Public key¶
A string combination of characters inextricably linked to the private key. The public key is attached to transactions to confirm the correctness of the user’s signature made on the private key
- Unconfirmed transaction pool (UTX pool)¶
A component of the Waves Enterprise blockchain platform that stores unconfirmed transactions until they are verified and sent to the blockchain
- Round¶
The process of mining a block by a blockchain network participant
- Repository¶
Smart contract image repository deployed with Docker Registry software
- Permission¶
Granting or denying of certain operations in the blockchain
- Network message¶
Network event information sent by a node to other nodes in the blockchain
- Smart contract¶
A separate application which saves its entry data in the blockchain, as well as the output results of its algorithm
- Snapshot¶
A set of all the blockchain current data on accounts, smart contracts, sensitive data access groups, permissions and registered nodes. A snapshot contains no history of changing values, transactions or blocks.
- Creation of a smart contract¶
Upload a new smart contract to the blockchain using transaction 103
- Soft fork¶
Mechanism for activating pre-built blockchain functionality
- State¶
Blockchain transaction history stored in the database of each node
- Address state¶
Data set of an individual address: balances, information about sent data transactions, results of execution of smart contracts called by the address
- Smart contract state¶
Current smart contract performance data recorded and updated with the transaction 104
- Token¶
A blockchain unit used to motivate participants to mine on the network
The object used to authorize the blockchain participant
- Transaction¶
A separate operation in the blockchain that changes the network state and is performed on behalf of a participant. By sending a transaction the participant sends a request to the network with a set of data necessary to change the state accordingly
