Polygon (POL)

Polygon (formerly Matic Network) is a Layer 2 / sidechain solution that enables users to access Ethereum applications (DApps) with reduced fees and near-zero latency.
In their research, the Matic Network team came across a publication byEthereum co-founder Vitalik Buterin and Lightning Network co-founder Joseph Poon, detailing a new scalability solution: “Plasma”.
This solution is based on the duplication of a parent blockchain, which can be copied more quickly while maintaining security.
The Plasma solution will form the basis of the Matic blockchain.
Matic Network becomes Polygon in early 2021.
Much more than a name change, this redesign signals a shift from a single blockchain to an aggregator of scalability solutions for Ethereum.
Any developer can create a scalable blockchain here.
Polygon works by connecting Ethereum DApps to a network of interconnected sidechains.
Users can therefore interact with DApps on the Polygon network without having to wait for block confirmations on the main Ethereum network.
Polygon’s key feature is its ability to handle several million transactions per second.
This is made possible by the use of Plasma and other cutting-edge technologies such as Proof-of-Stake protocol optimization and Shard Chains.
Polygon enables users to access Ethereum applications at low cost and with near-zero latency.
What’s more, the network is capable of handling several million transactions per second.

Polygon (MATIC) is a type of Layer 2 solution that enables other blockchains to bring greater scalability to applications by processing off-chain transactions.
All the while, they remain connected to the main chain.
This facilitates processing outside the main network.
At the same time, they can take advantage of the security and decentralization of the Ethereum backbone.
This flexibility speeds up processing times and reduces gas costs.
Chains built on the Polygon blockchain revolve around Matic tokens, the network’s native crypto.
Each sidechain is an independent blockchain that processes transactions and smart contracts autonomously.
However, these sidechains are interconnected with the Ethereum blockchain, enabling the transferability of assets between the different chains.
One of the fundamental aspects of Polygon is its ability to enable users to transfer their assets between the main Ethereum blockchain and Polygon sidechains.
This is done via bridges, which secure assets as they cross between the two networks.
Polygon offers various types of sidechain, adapted to different use cases.
These include PoS (Proof of Stake) sidechains, which use proof-of-stake consensus to validate transactions.
There are also PoA (Proof of Authority) sidechains, where a restricted group of entities is responsible for block validation.
Each type of sidechain has its own advantages and is adapted to specific use cases.
Although Polygon’s sidechains operate independently, they are linked to the Ethereum blockchain by security mechanisms such as “Checkpointing”.
This means that sidechain blocks are regularly “rooted” on the Ethereum blockchain, reinforcing the overall security of the Polygon network.
On Polygon PoS sidechains, consensus is reached via a staking mechanism.
Validators must lock up a certain quantity of MATIC tokens as collateral to be eligible to validate transactions.
Rewards in MATIC tokens are distributed according to participation in the consensus.
On the Polygon network, transaction fees are considerably lower than on Ethereum.
This makes interactions much more affordable for users and encourages adoption of the ecosystem.
One of Polygon’s other strengths is its interoperability with other blockchains.
It can interact with networks such as Binance Smart Chain and other blockchains via cross-chain bridges, enabling the transfer of assets between different platforms.
Polygon is used for a multitude of use cases, including DeFi (Decentralized Finance) applications, NFT (Non Fungible Tokens), blockchain gaming, and much more.
Its scalability and low transaction costs make it a highly attractive option for developers and users alike. The Polygon (MATIC) network is based on an architecture of interoperable sidechains that work in tandem with Ethereum.
It offers an efficient scaling solution by reducing transaction costs and increasing processing speed, while preserving Ethereum’s characteristic security and decentralization.
Thanks to these features, Polygon has gained in popularity as a versatile blockchain platform, attracting projects and developers from all over the world.
The Polygon network can be thought of as a set of four layers: – 1st layer: Ethereum layer – 2nd layer: security layer – 3rd layer: Polygon network layer – 4th layer: execution layer The network uses smart contracts to enable inter-chain transactions.
The connection technology is Polygon bridge, a bidirectional channel that does not require a trusted third party between Polygon and Ethereum (main chain).
The structure is designed so that Polygon chains can operate independently off-chain without overloading the main chain.
This reduces time and costs.
The PoS (Proof of Stake) and Plasma bridges are two key mechanisms that play a fundamental role in the operation of Polygon (formerly known as the Matic Network).
They enable the transfer of assets between the Ethereum blockchain and Polygon’s various sidechains.
Each of these bridges has its own characteristics and is designed to meet specific needs in terms of security and transfer speed. PoS (Proof of Stake) bridge: Polygon’s PoS bridge is a mechanism designed to transfer assets between the Ethereum blockchain and Polygon sidechains that use proof-of-stake (PoS) consensus.
When a user wishes to transfer assets from Ethereum to a Polygon sidechain, they send them to a specific address on the Ethereum blockchain.
These assets are then locked into a deposit address, meaning that they are temporarily set aside on the Ethereum blockchain.
Once the transaction is confirmed on Ethereum, the PoS bridge receives the notification and creates a corresponding record on Polygon’s sidechain.
This unlocks the corresponding assets on the sidechain.
The assets are then issued on Polygon’s sidechain, where they can be used in accordance with the functionality of that particular chain.
It’s important to note that this process is reversible.
If the user wishes to return assets from a sidechain to the Ethereum blockchain, the process is simply reversed.
The PoS bridge ensures a high level of security through the use of PoS consensus mechanisms on Polygon sidechains.
This ensures that transactions are securely validated before being finalized. Plasma bridge: Plasma bridge is another essential Polygon mechanism that enables the transfer of assets between Ethereum and Polygon sidechains.
Users begin by depositing their assets on a specific Plasma contract located on the Ethereum blockchain.
This contract is designed to manage the transfer process. Once the deposit is made on the Plasma contract, it is confirmed on the Polygon sidechain.
This creates a record of the asset on the sidechain.
The assets are then available on the Polygon sidechain and can be used in accordance with the functionalities of that particular chain.
When the user wishes to return the assets from the sidechain to Ethereum, they can make an exit request.
This means that the assets are locked onto the sidechain and a proof of exit is generated.
This proof of exit is then verified on the Ethereum blockchain to ensure that it is legitimate.
Once validated, the corresponding assets are released on the main blockchain.
The Plasma bridge guarantees a high level of security thanks to proof verification on Ethereum.
This ensures that transactions are secure and cannot be revoked once they have been confirmed. Comparison of the two bridges: The Plasma bridge relies on Ethereum-based proof verification, giving it a high level of security.
The PoS bridge, on the other hand, uses PoS consensus on sidechains, also offering a high level of security.
Plasma bridge can offer faster confirmation times, as it relies on proof verification.
The PoS bridge works with PoS sidechains, which can result in slightly longer confirmation times.
Both bridges enable bidirectional transfers between Ethereum and Polygon sidechains.
The Plasma bridge can be a little more complex to implement due to proof verification.
The PoS bridge is simpler to use and may be more developer-friendly.
Ultimately, both bridges are crucial components of the Polygon ecosystem, each bringing its own specific benefits depending on needs and use cases.
They enable users to take full advantage of the scalability offered by Polygon while retaining the ability to transfer assets to and from the Ethereum blockchain.

The MATIC token is the native token of the Polygon platform.
It plays several crucial roles within the Polygon ecosystem: – Payment of transaction fees: MATIC is used to pay transaction fees on the Polygon network.
When users carry out operations such as transferring funds or executing smart contracts on Polygon, they must use MATIC to pay the network’s validators. – Staking and Governance: MATIC holders can choose to stake their tokens in Polygon’s proof-of-stake (PoS) consensus mechanism.
By doing so, they participate in the transaction validation process and are rewarded in return.
In addition, MATIC holders also have the right to vote on governance proposals to influence decisions on the evolution and direction of the Polygon ecosystem. – Collateral for DeFi protocols: The MATIC token can be used as collateral for Decentralized Finance protocols running on Polygon.
This means that users can lock their MATIC tokens into smart contracts to borrow other assets, such as stablecoins, at specified interest rates.
–Participation in incentives and reward programs: Some projects and protocols on Polygon offer incentives and reward programs in MATIC to encourage adoption, participation and community involvement.
–Distribution of DeFi rewards: In the DeFi ecosystem on Polygon, users who provide liquidity or participate in yield farming mechanisms can be rewarded in MATIC according to their participation and protocol performance.
–Partnerships and integrations: MATIC is often used as a means of payment for partnerships and integrations within the Polygon ecosystem.
It can be used as an incentive for developers and projects to build or integrate solutions on the platform.
It’s important to note that the role and uses of the MATIC token may evolve over time as network updates and new features are introduced.
As Polygon’s native token, MATIC plays a central role in the platform’s economy and ecosystem.
