The information about the block itself (block metadata), including a

timestamp, a hash representation of the block data, the hash of the previous

block’s header, and a cryptographic nonce (if needed), is contained in this

portion of a block.

Block reward

For successfully adding a block to the blockchain, a reward (typically

cryptocurrency) is awarded to the publishing nodes.

Blockchain

Distributed digital ledgers of cryptographically signed transactions that are

grouped into blocks is a blockchain. After validation and undergoing a

consensus decision, each block is cryptographically linked to the previous

one (making it tamper evident). Older blocks become more difficult to

modify (creating tamper resistance) as new blocks are added. Any conflicts

are resolved automatically using established rules as new blocks are

replicated across copies of the ledger within the network.

Blockchain network user

A blockchain node is a blockchain network user, which may be any single

person, group of persons, business, or organization which is using or

operating it.

Proof of stake consensus model—Byzantine fault tolerant

The blockchain decides the next block by allowing all staked members to

“vote” on which submitted block to include next is the Byzantine Fault

Tolerant proof of stake consensus.

Centralized network

A network configuration where participants must communicate with a

central authority to communicate with one another is a centralized network.

The loss of the single centralized source would prevent all participants from

communicating since all participants must go through that source.

Proof of stake consensus model chain-based

Here, the blockchain network decides the next block through pseudo-

random selection, based on a personal stake to overall system asset ratio is
