Hello..!!

My Dear Friends
This is @ns-porosh from Bangladesh 🇧🇩

Introduction

How are you all? I hope you are well by the grace of God.I am well with your prayers and mercy God's grace.At first of all thank you to the sir @pelon53 Your lesson provides a lot of information on homework tasks. Today I am going to learn about Avalanche blockchain through this lecture.
Anyway let's get started now......

1.-Explain X-Chain, C-Chain and P- chain in detail.

Avalanche blockchain features high transaction speed, low cost and eco-friendliness. The Avalanche blockchain was first launched in 2018 by Kevin Sekniki, Maufan "Ted" Yin and Emin Gunn, and later launched in September 2020. Avalanche Blockchain uses three different blockchains, and the functions of each blockchain include decentralization, security, and scalability. The three blockchains include Exchange Chain (X-Chain), Contract Chain (C-Chain), and Platform Chain (P-Chain). These three different blockchains are fully valid on the main network and using three different blockchains, the Avax blockchain network platform has been able to share the responsibility of the trilogy in three different blockchains. Below is a detailed discussion of Exchange Chain (X-Chain), Contract Chain (C-Chain), and Platform Chain (P-Chain).

X-Chain

---

We already know that Avalanche blockchain uses 3 different blockchains. X-chain is the first blockchain used in Avalanche. The X-chain of the Avalanche network is an acronym for Exchange Chain. A user can easily create and transfer assets through this chain. X-chain is a decentralized chain. In order for a user to create an Avalanche-based token, the user must follow the rules of the Consensus Protocol used by the chain. Exchange chains (X-chains) are also used to exchange tokens or trade and exchange tokens. Fees are required when transactions are made by this chain, which is paid in AVAX.

---

C-Chain

---

The C-chain is the second of three different chains in the Avalanche ecosystem. C-chain is an acronym for Contract Chain. Basically this chain allows developers to create their smart contracts to create decentralized applications. This means that developers will be able to create their own smart contracts through this chain.Compatible with C-Chain Etherium Virtual Machine For this, C-Chain uses Etherium Virtual Machine to create smart contracts.

---

P-chain

---

The Avalanche blockchain ends within 3 separate blockchains or another P-chain which is short for platform chain. P-Chain basically lets users create their own subnet and allows them to add verifiers to the subnet. The main purpose of this chain is to bring together verifiers and create more new subnets. Now what is the subnet? The subnet is a group of verifiers who collectively work together on the blockchain. Also the prizes of the verifiers are received through P-chain.

2.-Explore the Avax Network platform. Screenshots required.

After clicking on the last block I got more information about the block. The blue border section of the screenshot above is marked.

5:-Explain in detail the Avalanche consensus protocol and the Snowman consensus protocol.

Avalanche consensus protocol

The Avalanche Consensus Protocol is a decentralization protocol where no leader is needed to legitimize the transaction. Usually in other protocols like PoW, PoS, DPoS a transaction is processed by a single node and then other nodes validate the transaction. However, since the Avalanche Protocol does not require a leader, all nodes in the Avalanche Protocol transact at the same time using the Direct Acyclic Graph (DAG) system. Transactions made through the Avalanche Consensus Protocol are valid in parallel and transactions are verified very efficiently. This in turn increases the speed and scalability of the decentralization period. This ensures that users can transact very quickly.

Snowman consensus protocol.

The Snowman Consensus Protocol is a protocol based on the Avalanche Consensus Protocol. In this protocol, blocks and transactions are created and sorted in a linear manner to facilitate easy recording of smart transactions. Also in protocol transactions are not done in parallel and with the help of smart contract transactions are completed very efficiently.

Conclusion

From this lecture of Sir I have gained a lot of knowledge about Avalanche Blockchain.
Avalanche Blockchain ensures complete decentralization of a user and can complete transactions very quickly. Compared to all the blockchains in the world today, the power of this blockchain error is very low and due to which this blockchain will gradually become very popular in the world. Moreover, this blockchain has a very high level of scalability and the ability to transact much more per second. Thank you very much sir @pelon53 for this beautiful lesson.
