Polygon stands as a prominent Ethereum scaling solution. The platform was established by Sandeep Nailwal, Jaynti Kanani, Anurag Arjun, and Mihailo Bjelic. The network achieves scalability through the use of sidechains that process transactions off-chain while safeguarding assets via the Plasma framework and a distributed collection of Proof-of-Stake (PoS) validators. By August 2022, the platform had attracted more than 37,000 decentralized applications utilizing its infrastructure.
During February 2022, Polygon secured approximately $450 million from a private token sale of MATIC, its native cryptocurrency, in a fundraising round directed by Sequoia Capital India.
Polygon received recognition in June 2022 when Disney selected it as a participant in the 2022 Disney Accelerator initiative, a program focused on fostering growth of forward-thinking enterprises globally. The 2022 Disney Accelerator cohort emphasizes the development of immersive technology experiences and focuses on fields including augmented reality (AR), non-fungible tokens (NFTs), and computational character intelligence.
Subsequently, the Polygon development team introduced zkEVM, representing the first Layer 2 zero-knowledge solution that is equivalent to the Ethereum Virtual Machine.
Matic Network
The network was originally introduced as Matic Network in 2017 with a mission to foster a more transparent and accessible world through improvements to the Ethereum infrastructure. Over a three-year period, the developers constructed and deployed Matic Plasma Chains, a market-ready Ethereum Layer 2 implementation. The team also developed and introduced Matic PoS Chain, an open-access, EVM-compatible, PoS-validated Ethereum sidechain that depends on Ethereum's infrastructure for validator staking and transaction verification. Throughout this period, Matic attracted more than 80 projects, such as Polymarket, Aavegotchi, Neon District, SkyWeaver, Cometh, and EasyFi, with additional applications continuously joining the network.
Polygon
In February 2021, Matic Network announced its evolution into Polygon, the inaugural comprehensive, accessible framework for achieving Ethereum scalability and building scaling infrastructure.
Polygon represents a departure from its earlier iteration by implementing a comprehensive, multi-layered methodology. Polygon aims to evolve Ethereum into a genuine multi-chain system that incorporates numerous forms of Layer-2 scaling approaches, extending beyond the initial solutions delivered by Matic Network. Polygon provides multiple approaches to resolving Ethereum's capacity constraints - reflected in the 'poly' component of its rebranded identity. Though Polygon continues to focus on sidechain integration and operates its primary PoS chain since April 2021, it intends to broaden its offerings to incorporate additional Layer-2 methods including zkRollups, Optimistic Rollups, independent sidechains, corporate-grade chains, distributed security models, and cross-chain messaging technologies. Consequently, Polygon characterizes itself as a comprehensive toolkit for Ethereum scaling and infrastructure advancement.
Polygon blockchain information became accessible through Google Cloud Platform in May 2021. By connecting with Google BigQuery, developers gained the capability to examine on-chain Polygon activity more efficiently. Following the BigQuery integration, Polygon's data repositories were cataloged in the Google Cloud Marketplace within the public financial services classification. The integration offers potential advantages including observation of transaction costs, smart contract activity, and identification of the most utilized assets and platforms within the system.
According to data compiled by Alchemy in August 2022, the leading Web3 development infrastructure provider, Polygon hosted more than 37,000 decentralized applications. This growth marks a quadrupling of applications from the start of 2022 and represents nearly double the quantity documented in March 2022.
- PoS Chain: Polygon's primary chain operates as an Ethereum sidechain identified as the Matic PoS Chain, which incorporates a Proof-of-Stake (PoS) security mechanism for chains operating within the Polygon network.
- Plasma Chains: Polygon leverages Plasma as a scaling mechanism to facilitate the transfer of value between the base chain and subordinate chains by means of Plasma connection technologies.
- ZK-rollups: A scaling approach that bundles numerous transactions off-chain into a solitary on-chain record, employing zero-knowledge mathematical proofs to establish finality on the Ethereum base layer.
- Optimistic rollups: A scaling methodology operating above Ethereum that facilitates rapid transaction settlement by utilizing proofs of fraudulent activity.
Payments
Polygon offers a framework that permits decentralized applications (DApps) to accelerate transaction settlement, enabling near-instantaneous transfer confirmation through specialized application interfaces (API) and development packages (SDK) connections. Through this mechanism, applications, service providers, and participants can promptly handle transactions or transfer funds in various cryptocurrencies, predominantly ERC-20 standards or ETH. The system is being implemented through three progressive stages:
- Ethereum (ETH) and ERC-20 standard token transfers.
- Multi-token transfers between different chains and payments utilizing swapped transactions in cooperation with market makers.
- Currency-denominated payment systems utilizing traditional currency liquidity sources.
Polygon is establishing a system enabling service providers to evaluate the creditworthiness of platform participants by examining their prior transaction behavior. This functionality is being produced in association with Dharma.io. The major borrowing and lending service Aave ($AAVE) maintains more than $1 billion in deposited capital across its Polygon offerings with engagement from more than 8000 participants.
Games
Polygon's Layer-2 sidechain scaling mechanism has the capacity to enhance the speed and efficiency of cryptocurrency-based gaming. Blockchain-based gaming currently underperforms relative to mainstream desktop and console gaming because of limited processing capability and increased communication delays. By combining Polygon's Commit Chain mechanism with the Ethereum system, designers and players gain enhanced capability to develop and engage with games. Polygon's contribution to fostering blockchain gaming comes at a significant moment, as blockchain collectibles (NFTs) and related transaction platforms are increasingly driving interest in digital assets, with numerous participants acquiring, exchanging, and dealing in varied gaming collectibles. Leading gaming and collectible applications including Aavegotchi, Neon District, Zed Run, and Cometh have utilized Polygon to expand their user engagement and scalability.
