between nodes manifesting as inconsistently high latencies in

applications.

Considering the interoperability among the networks with smart

contract integrations or calls, the security issues of one network can

easily be slid into another network which may undermine the Security

of the complete network.

Computing power is involved with consensus models with Cost of

Participation in the form of infrastructure, and any change in it can

change the participation cost, which has a significant impact on the

base network, as well as networks inter-operating with the base

network.

Consensus models based on how easy or difficult it is to achieve

scalability can have a high impact on the Scalability of the network.

The issue can spill over the integrated networks and have replicating

effects across the complete network.

Considering the security, performance, and functional challenges, it can be

an extremely challenging situation for the blockchain networks, which are

already on for a change in consensus models.

When considering the aspects such as public vs. private network, real-world

use, trustful vs. untrusted players, the selection of the right consensus model

is critical. The core of the blockchain networks, which can have a strong

influence on the design and overall capability of the blockchain, even

defining the success or the failure of the blockchain network, is formed by

the consensus models. This is a widely invested field with many frequent

advances, and blockchains use consensus algorithms to elect a leader who

decides the contents of the next block.

The popularly used consensus models are as follows:

Proof-of-Work (PoW)

Practical byzantine fault tolerance (PBFT)

Proof-of-Stake (PoS)

Round Robin

Proof-of-Authority (PoA)

Proof-of-Identity (PoI)
