Based on official weblog of Polygon Labs, Ethereum’s scaling downside is not a brand new conundrum, with its historical past being nearly as historic as Ethereum itself. What makes Ethereum uniquely strong is its regular evolution, guaranteeing the chain’s security and decentralization. However the query arises, how does Polygon goal to enhance Ethereum’s scalability?
Understanding Layer 1 (L1) and Layer 2 (L2)
L1 and L2 are sometimes termed because the “father or mother” and “little one” 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. Nonetheless, the duty of reaching consensus—verifying transaction information and updating all blockchain accounts—falls to L1.
Ethereum’s cautious development in direction of consensus prioritizes safety over velocity. Consequently, any perceived “slowness” in Ethereum is a consequence of its emphasis on security.
Layer 2: A Resolution to the Blockchain Trilemma
A traditional engineering rule states: one can obtain both two of fine, low-cost, and quick concurrently. Within the blockchain context, the pivotal parts 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 improvement section, a number of intermediate options existed, every with its distinctive strategy to the trilemma.
Completely different Approaches to Scaling
State Channels: Current off-chain, these make the most of an on-chain sensible contract to permit customers to deposit property. The catch? They operate with out L1 interplay and require a better belief stage 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. Curiously, ZK proofs can affirm the authenticity of a transaction batch with out divulging particular particulars—a characteristic that reinforces scalability with out compromising on safety or decentralization.
Polygon’s Position in Ethereum’s Scaling
Polygon 2.0 envisions to cater to numerous 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 while not 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 charge of simply $0.015. Polygon Labs has plans to rework 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 concentrate on a ZK-centric design. This design extends the capabilities of EVM, facilitating the event of functions difficult to comprehend on account-based programs 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 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.
