Plasma Chain: What is it?

Plasma chains are chains that are linked to Ethereum and allow fraud-proof arbitration (like optimistic rollups). Almost all these chains are children of the Ethereum Mainnet and are called “child chains”. The Merkle tree allows for a limitless number of chains to be stacked and use their bandwidth to offload the parent chains (including Mainnet). Each child chain validates its blocks, and the child chains use fraud proofs as their security.

Key elements:

The components of plasma are:

  • Continuous contract measurement would have an economic advantage.
  • To optimize output at a reduced cost, child chains are arranged in a tree-like shape.
  • By the tree architecture for reshaping state transitions to increase scalability, we use MapReduce to build Proof-of-Fraud for state transitions in inserted chains.
  • An algorithm that emulates the Nakamoto Consensus Drivers by using the parent blockchain
  • Implementing a map-UTXO architecture to reduce exit costs by accurately moving states from the parent blockchain. The central concept of Plasma release is exit permission for inaccessible data or other Byzantine considerations.

Why it is important?

The benefit of Plasma is that it can significantly ease Ethereum’s congestion, just as state channels do. Developers want their dApps to reach scale, while users want lower fees and greater throughput. Through this new project, the Ethereum community may be able to reach a larger audience.

 The state channel and the plasma channel can also be combined to produce compounding effects. The work on state channel implementations within child chains is being carried out by many groups. Within child chains, users would be able to transact at a low cost and spend funds outside of their child chains without incurring fees.

It is still premature to tell how Ethereum’s second layer will develop, but from where it is now, every developer should feel enthusiastic about Ethereum.

The Architecture of Plasma

  • All blockchain calculations are understood as MapReduce structures, plus a token linkage method at the front of preexisting blockchains to support Nakamoto Consensus Drivers and disallow block restriction. By using the Proof-of-Fraud method, a smart contract is implemented on the root blockchain to guarantee this form of architecture.
  • Using an elaborate tree-like structure, the Ethereum team organizes blockchains individually under an enforced blockchain background with Merkle proofs embedded in MapReducible calculations. The deceptive nature of a root blockchain causes users to lose trust in its accuracy and presence. By reframing a block into a child blockchain, users can gain a wider scale without affecting the accuracy or presence of the root chain.
  •  A blockchain’s correctness is typically verified by each participant testing the chain. For any new block to be considered, it must be checked thoroughly for accuracy. Many efforts to speed up the blockchain transaction rate require the use of temporary obligations to create a reliable bond, which, in this way, ensures participant compliance with the regulations. With the assert-challenge architecture, the correctness of a given state could be determined.
  • Blockchain can be used to punish a party committing a fraudulent act or misdemeanor. Essentially, it provides a framework to facilitate enforcement of consequences, but only if and only if a false claim is made. As a result of this assert/challenge/proof system, participating parties will claim ground truths on the fundamental blockchain to non-participating parties. Blockchain is a technology that can be used for payments as well as computation, so it can be the decision-making system for contracts.

 Root Contracts:

As well as serving as a bridge, root contracts help users move assets between the Ethereum network and the child chains. To become an asset on Ethereum, it has to be initially created on Ethereum. The goal is to prevent malicious activity from being brought back from a child chain to the parent chain. Alice can always withdraw assets from the child chain and use them on the main Ethereum network if she moved three crypto collectible NFTs onto it and proved she had never spent them.

 Malicious Activities Can Be Protected By Plasma

Children’s chains, which are largely controlled by central entities, are the focus of most potential malicious activity. When a blockchain operates as a DPoS or PoA system, a limited number of parties produce and validate blocks, which increases the chances of a block being corrupted. Users can submit proofs of fraud against the work of any block producers through Plasma, creating a check on economic incentives for them.

 The Plasma vs. the State Channel

Using state channels and Plasma is similar in the sense that transaction bloat is moved away from the main chain as much as possible. When a dispute or a user wants to stop transacting in the child blockchain, state updates can always be brought back to the Ethereum network.

A chain of children can be of varying complexity. It allows each application to have its consensus mechanism, its block size, and its own confirmation time, making the design very flexible. There have even been attempts by developers to create hidden child chains within other child chains.

We don’t need to validate every transaction on the Ethereum blockchain directly for dApps to be created that serve tens of thousands, if not hundreds of thousands, of users today.
