output pattern), this is a consensus model where a publishing node wins the

right to publish the next block.

Reward system

An award for activities is provided to the blockchain network users within

the blockchain network (used as a system to reward the successful

publishing of blocks). It is also known as an incentive system.

The round robin consensus model

Here, nodes are pseudo-randomly selected to create blocks, but a node must

wait for several block-creation cycles before being chosen again to add

another new block. It is the consensus model for permissioned blockchain

networks.

It

benefits

from

a

straightforward

approach,

lacking

cryptographic puzzles, having low power requirements, and ensures that no

one participant creates the maj ority of the blocks.

Smart contract

Deployed using cryptographically signed transactions on the blockchain

network, it is a collection of code and data (functions and state). It is

executed by nodes within the blockchain network; all nodes must derive the

same results for the execution, and the results of execution are recorded on

the blockchain.

Soft fork

An implementation of a blockchain that is backward compatible with a

change is a soft fork. The non-updated nodes can continue to transact with

updated nodes.

Tamper evident

The process of making alterations to the data easily detectable is tamper-

evident.

Tamper-resistant

The process of making alterations to the data difficult (hard to perform),

costly (expensive to perform), or both are temper resistant.
