Polygon supernets vs. Avalanche subnets: Key variations

by Jeremy

Supernets have a complicated technical structure powered by Polygon Edge, trustless operation through Merkle bushes, Ethereum Digital Machine (EVM) compatibility and customized token help.

Supernet structure is intently tied to that of Polygon Edge. The six modules in Polygon Edge’s structure which can be related to supernets embrace the next:

  • TX Pool: Performing as a repository for pending transactions, this module is the important thing to Polygon Edge’s event-driven structure. Transactions could be added simply from a number of sources, and it seamlessly hyperlinks up with different modules of the platform.
  • Blockchain: This refers back to the state database, and it holds info on accounts, sensible contract code, world state and extra.
  • JSON-RPC: The supernet’s API layer complies with Ethereum consumer requirements, enabling instruments reminiscent of MetaMask, Web3.js, Ethers.js, Remix and Hardhat to run seamlessly on its community.
  • Consensus: Supernet makes use of proof-of-authority and proof-of-stake consensus algorithms.
  • Libp2p: That is supernet’s up to date peer-to-peer networking stack that facilitates block syncing, consensus messages, transaction pool gossiping and SAM pool gossiping.
  • gRPC: With its highly effective communication protocol, privileged operator instructions on a supernet can solely be domestically executed on validator nodes. Validated operators can carry out on-line backups, get hold of info from validator methods, and question and clear knowledge saved within the transaction pool.

Supernets additionally function trustlessly, which means that every node validates each transaction independently by executing the sensible contract. For the blockchain ledger to perform correctly, all nodes should maintain an equivalent copy of it, consisting of a Merkle tree of blocks and intensive lists of transactions. 

An effort by malicious actors trying to change the ledger might be swiftly recognized as a result of discrepancies in hash values from the totally different states incompatible with these throughout the Merkle tree.

Supernets even have built-in EVM help, which means that builders can write and deploy sensible contracts utilizing EVM bytecode, which is compiled from high-level languages, reminiscent of Solidity.

Builders with Ethereum constructing expertise can simply switch their Solidity contracts to supernets with none modifications because of the suite of instruments obtainable, together with Truffle, MetaMask, Remix and block explorers. This enables for a seamless transition from one platform to a different.

Lastly, supernets enable builders to create customized tokens in keeping with universally acknowledged token interfaces, reminiscent of ERC-20. That is in step with Polygon’s purpose of selling interoperability through supernets.
