I first heard about Matic Chain on a Twitter like social media, Swirge. Swirge is a blockchain based social media that was built on the Binance smart chain. It was a surprise to read the CEO of Swirge swerve that for quicker site loading, Swirge is going Multichain and it has chosen Matic Chain as it's second chain alongside Binance smart chain.

When Swirge finally implemented the Matic Chain integration to become multi chain, you can easily switch between using Swirge on either Binance or Matic Chain. Using it on Matic Chain, I noticed it's quite faster than using it on Binance chain. This got me curious to learn more about Matic Chain.

Matic Network

Matic is a protocol and Framework for building and connecting Ethereum compatible blockchains networks thereby making Ethereum network an Internet of Blockchains. Backed by Binance and Coinbase, Matic Chain is a layer 2 scaling and infrastructural development solution on Ethereum and the first on the Ethereum network.

The core component of Matic Chain is Polygon SDK, a flexible Framework that support building multiple DApps. Matic network transaction per second is about 65,000 on a single side chain and transaction confirmation time of less than 2 seconds. Matic Chain TPS makes it attractive to dApp builders and has attracted over 50 DApps one of which is Swirge.

One feature on Matic network that excites me the most is how you can deploy Matic as ZK Roll-up Chains, Optimistic Roll-up Chains, and as a Stand-Alone Chains. With Matic operating as a Stand-Alone Chain, it can transform the Ethereum network into a full fledged Multichain system.

• ZK(Zero Knowledge) Roll-up: Ethereum layer 2 solution based on driving succinct validity proof that get submitted and verified on Ethereum network periodically;

• Optimistic Roll-up: Ethereum layer 2 solution based on fraud proofs. This is better described as proofs of malicious actions that get submitted and resolved on the Ethereum network; and

• Stand-Alone Chain: Matic is deployed as a blockchain, secured by it’s own set of validators and optionally connected to Ethereum via bridges. In this case, Matic becomes an Ethereum side chain.

Architecture

Matic network architecture consists of four (4) abstract, composable layers.

1. Ethereum layer.

2. Security layer.

3. Polygon Network layer.

4. Execution later.

Ethereum layer: Matic Chain can use Ethereum to host and execute any mission critical component of their logic. This is implemented using Smarts contracts on Ethereum network to perform functions like;

• Staking

• Dispute resolving

• Message relaying

• Finality/Check Pointing

Security layer: This is a specialized, non mandatory layer, managing a set of validators that can periodically check the validity of any Matic Chain for a fee. This layer performs functions like;

• Validators managements

• Matic Chains validation.

Polygon Network layer: A constellation of sovereign Blockchain networks. Each of these networks serves the Matic community, maintaining functions like;

• Transaction collation

• Local consensus

• Blocks productions.

Execution layer: This is the layer that interprets and execute transactions that are agreed upon and included in Polygon networks blockchains. This layer consists of two sublayers: Execution Environment and Execution logic.

Presently, Matic supports two major types of Ethereum compatible blockchain networks: Stand-Alone network and networks that leverage “Security as a service”. Matic currently supports only Ethereum base chain but plans are underway to make Matic an interoperable Decentralized layer 2 Blockchain platform.
