Multichain 101 : Understanding Polygon Blockchain Ecosystem

ENEDEX multichain is coming very soon. Multiple blockchain has been prepared for seamless swapping experience across cryptoverse. But before the release of ENEDEX multichain, let’s learn more about the blockchains that potentially will be in ENEDEX multichain. In this iteration let us deep dive on one of the most versatile blockchain in the world and the OG L2, Polygon!

The Polygon Network is a crypto project dedicated to making the Ethereum blockchain increasingly user-friendly. The origins of Polygon date back to 2017 when developers Jaynti Kanani, Sandeep Nailwal, and Anurag Arjun began exploring ways to improve Ethereum’s throughput without sacrificing its decentralization. To do this, Polygon’s team focused on building distinct blockchain solutions that interact with Ethereum’s main chain.

After raising millions in initial coin offerings (ICOs), Polygon went live in 2020. The India-based software company Polygon Technology is primarily responsible for building the Polygon Network. Polygon also has a nonprofit organization called the Polygon Foundation that helps organize, raise funds, and coordinate development on the Polygon blockchain.

Since its debut, Polygon has attracted considerable attention from businesses, Web3 developers, and prominent investors like Mark Cuban. As of 2022, the Polygon Network estimates more than 20,000 dApps are using Polygon’s services. Other big companies that have partnered with Polygon include Facebook’s Meta, the Walt Disney Company, and Atari.

There’s a lot of heady tech involved in the Polygon Network, but its key goal can be summed up in two words: Ethereum scalability. It’s important to note that Polygon doesn’t offer just one solution to this issue. Indeed, the Polygon team wants to provide developers and users with multiple tools to build on Ethereum.

Since every scaling solution has pros and cons, Polygon wants to give people as many options as possible to create a dApp that fits their specifications. For instance, some dApp developers may prioritize security over speed, while others may be willing to sacrifice some safety for cheaper fees. Polygon is building multiple Ethereum-based scaling solutions with slightly different features.

At the start, Polygon offered two services:

  • Plasma chains
  • The Polygon PoS sidechain

Plasma chains and sidechains share some similarities, but they are slightly different technologies. Plasma chains are always connected (or “rooted”) to a primary blockchain like Ethereum. Sometimes called “child chains,” plasma chains derive all of their security from their layer one blockchain (aka the “root chain”). Even though plasma chains can resolve transactions off-chain, they are intertwined with the root chain thanks to bridges and smart contracts.

By contrast, sidechains run parallel to the main chain and have their own consensus and governance mechanisms. For instance, Polygon’s sidechain uses a separate Proof-of-Stake consensus mechanism independent of Ethereum. Instead of bridging transaction data to the main chain, sidechains usually take “snapshots” of transaction history at regular intervals. The sidechain will communicate this data with the main chain using smart contracts to ensure they agree.

The relative freedom sidechains enjoy gives them greater flexibility and speed. However, since sidechains rely heavily on independent governance and consensus mechanisms, they don’t have the robust security of the primary blockchain. Remember that plasma chains are always “rooted” to the main chain, which means they enjoy the same decentralization as the Ethereum network. This gives plasma chains greater security, but they might limit the freedom developers would have on a sidechain.

  • Low gas fees: People prefer Polygon over Ethereum because the former costs less per transaction. As a PoS sidechain, Polygon can quickly process “batches” of transactions, resulting in cheap gas fees. On average, people don’t have to pay more than a penny to make a trade on Polygon.
  • Fast transaction speed: Related to the last point, Polygon provides faster transactions per second versus the Ethereum main chain. Polygon claims it can handle 7,000 transactions per second, thus eliminating the congestion-related worries on Ethereum.
  • High-profile and secure: Although Polygon’s PoS chain may not be as decentralized as Ethereum, it has a strong reputation for security in the crypto industry. As one of the leading layer-two blockchains, Polygon is well-funded and has many of the most talented Web3 developers. It also derives its security from Ethereum, the oldest and most prominent smart contract blockchain.

These are 20 among hundred plus projects that is built on Polygon

Polygon has positioned itself as one of the top crypto projects helping bring more people into the Ethereum ecosystem. As Ethereum’s core developers continue to refine the main chain, Polygon allows people to enjoy all Ethereum offers without exorbitant gas fees and slow transaction confirmations.

While there are questions over Polygon’s use case after Ethereum’s main chain upgrades, there’s no question Polygon serves a purpose in today’s crypto ecosystem. Scaling solutions like Polygon will likely continue introducing innovative ways to attract more people to Web3.
