This article mainly shows you "what are the Avanlanche consensus algorithms", which is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn this article "what are the Avanlanche consensus algorithms?"

Avanlanche consensus algorithm Family: Slush, Snowflake,Snowball and Avalanche

Slush

Slush has the following properties:

No memory attribute

Each round of communication does not communicate with all nodes, but with K randomly selected nodes.

By selecting the number of m rounds, the final convergence with high probability can be guaranteed.

Slush is not a Byzantine algorithm.

Snowflake

Snowflake adds a counter to each node.

1. Each node has a counter

two。 Every time the color changes, the node's technology returns to zero.

3. Upon every successful query that yields k responses

For the same color as the node, the node increments cnt.

Snowball

The counter of the Snowflake algorithm is temporary, and each color conversion will cause the counter to return to zero. Snowball introduces a confidence count (Confidence Counter)

For each successful query, add one to the confidence count of the node

If the current confidence count of the node is less than the confidence count of the new color, change the color

Avalanche

Avalanche protocol combines the characteristics of non-Byzantine consensus algorithm and Satoshi Nakamoto consensus algorithm, and has obvious advantages:

Fast settlement and low latency: it only takes about 2-4 seconds to settle transactions worldwide. This means that the payment verification has been completed four seconds after the settlement order was initiated. Compared with the current mainstream blockchain networks, such as BTC, Ethernet Square and Alogrand, the confirmation delay time is greatly reduced.

Higher throughput: TPS up to 1300, processing 1000-10000 transactions per second, significantly higher throughput than BTC, Ethernet Square, and Alogrand

Robust: the network does not need to agree on the identity of the participants.

Static protocol: more importantly, the protocol is "green". This means that it is sustainable, does not waste energy, there is no special miner ecosystem, and the interests of miners and users do not overlap.

High scalability: lightweight protocols ensure high scalability and low latency. Byzantine attack tolerance is high: it allows a large number of Byzantine participants to exist, but will not have a material impact on network security. It can tolerate up to 50% of Byzantine nodes (that is, nodes that try to deceive the network and keep the entire network unbalanced).

Egalitarianism: avalanche protocols create an equal ecosystem where all nodes in the network have the same rights and interests.

Conflict trading is not protected: if an attacker tries to spend the same amount of money on two different transactions, the avalanche protocol will not be able to make a choice and the money will be lost. Classic consensus and Nakamoto Satoshi consensus will choose one of the deals, but the avalanche agreement will not. This interesting attribute secretly and naturally punishes bad characters, and the protocol itself does not add any additional reading costs.
