In keeping with official weblog of Polygon Labs, Ethereum’s scaling drawback is not a brand new conundrum, with its historical past being virtually as historical as Ethereum itself. What makes Ethereum uniquely sturdy is its regular evolution, guaranteeing the chain’s security and decentralization. However the query arises, how does Polygon intention to reinforce Ethereum’s scalability?
Understanding Layer 1 (L1) and Layer 2 (L2)
L1 and L2 are sometimes termed because the “dad or mum” and “baby” chain respectively. Whereas the L1 operates independently, L2 has sure dependencies on L1, primarily for safety and transaction information storage. The essence of all Ethereum L2s is to course of and execute transactions, successfully making L2 an execution layer. Nevertheless, the duty of reaching consensus—verifying transaction information and updating all blockchain accounts—falls to L1.
Ethereum’s cautious development in the direction of consensus prioritizes safety over velocity. In consequence, any perceived “slowness” in Ethereum is a consequence of its emphasis on security.
Layer 2: A Answer to the Blockchain Trilemma
A basic engineering rule states: one can obtain both two of excellent, low cost, and quick concurrently. Within the blockchain context, the pivotal components are decentralization, scalability, and safety. Given the importance of safety and decentralization, L2 emerges as the first answer to deal with scalability considerations.
Whereas many L2s had been nonetheless of their growth part, a number of intermediate options existed, every with its distinctive method to the trilemma.
Totally different Approaches to Scaling
State Channels: Current off-chain, these make the most of an on-chain good contract to permit customers to deposit property. The catch? They perform with out L1 interplay and require the next belief degree as a result of their distinct transaction validation and dispute decision logic.
Plasma Chains: Plasma chains submit periodic transaction summaries to the L1 within the type of block commitments, requiring lesser belief than state channels.
Rollups: The elemental distinction between sidechains (like state channels and plasma chains) and real L2s is their safety assurance. Whereas sidechains use consensus mechanisms, L2s make use of cryptographic proofs. Amongst rollups, ZK rollups leverage validity proofs, and optimistic rollups make the most of fraud proofs. Apparently, ZK proofs can verify the authenticity of a transaction batch with out divulging particular particulars—a function that enhances scalability with out compromising on safety or decentralization.
Polygon’s Position in Ethereum’s Scaling
Polygon 2.0 envisions to cater to various use-case necessities, guaranteeing the scalability of every. The current Polygon protocols embody Polygon PoS, Polygon zkEVM, and Polygon CDK, with the forthcoming addition of Polygon Miden. Notably, these chains are designed to be interoperable, permitting swift cross-chain transactions without having a direct bridge to Ethereum.
Polygon PoS: Launched in 2020, this community has overseen greater than 2 billion transactions from over ten thousand dApps, at a median transaction price of simply $0.015. Polygon Labs has plans to remodel Polygon PoS right into a zkEVM validium, which might successfully convert it into a real L2.
Polygon zkEVM: A ZK rollup that mirrors the Ethereum Digital Machine (EVM), guaranteeing a seamless expertise for Ethereum builders. Since its inception on Mainnet, it has processed over 5 million transactions from 400,000 distinctive addresses.
Polygon Miden: One other ZK rollup, however with a give attention to a ZK-centric design. This design extends the capabilities of EVM, facilitating the event of purposes difficult to understand on account-based methods like Ethereum.
Polygon CDK: An open-source equipment to develop ZK-powered L2s, guaranteeing scalability, safety, and sovereignty.
In essence, the evolution of the Polygon ecosystem is steadily aiding within the realization of a extra equitable future by way of the mass adoption of Web3. To maintain abreast of Polygon’s progress, fans are inspired to observe the Polygon Labs Weblog and different related communication channels.
