Polygon knowledge layer

Polygon knowledge layer. Polygon zkEVM is a zero-knowledge rollup (or zk-rollup) designed to emulate the Ethereum Virtual Machine. If you’re a new Web3 developer, it’s unlikely that you’ll need to run your own full node on Polygon. 10. Below are some of the key features of CDK: Security: CDK builds high-performance, high-security, scalable L2s that utilize the latest innovations in zero-knowledge technology such as Plonky3 . These checkpoints are attested by a majority of the validator set before being validated and submitted on Ethereum contracts. Polygon PoS testnet (Amoy) Polygon PoS mainnet; Polygon zkEVM testnet (Cardona) Polygon zkEVM mainnet The bridge will undergo modifications, with community approval, to change the native token of Polygon PoS to the new POL token. Whether you’re setting up a full node, validator node or troubleshooting, these commands will assist you in managing your Polygon PoS environment effectively. Jul 25, 2022 · Polygon zkEVM, which stands for zero-knowledge Ethereum Virtual Machine, leverages the power of zero-knowledge (ZK) proofs to reduce transaction costs and greatly increase throughput, all while inheriting the security of Ethereum. Polygon gas station has been deployed both on the Polygon mainnet & Amoy testnet. Retrying again in 5 seconds to fetch data from Heimdall path=bor/span/1¶. The majority of snapshot providers have also outlined the steps that need to be followed to download and use their respective client snapshots. Configure service files for bor and heimdall¶ Execute transactions on Polygon PoS without changing provider on MetaMask (this tutorial caters to MetaMask’s in-page provider, can be modified to execute transactions from any other provider) Under the hood, user signs on an intent to execute a transaction, which is relayed by a simple relayer to execute it on a contract deployed on Polygon Polygon Portal. Handles block producer selection. The Polygon Faucet is a tool provided by Polygon and ecosystem partners like Alchemy, QuickNode, and GetBlock. This quick start guide shows you how to deploy a zkEVM rollup stack on your local machine. Pragmas are common instructions for compilers about how to treat the source code (e. Polygon consists of the three following layers: Ethereum layer: A set of contracts on the Ethereum mainnet. Use the Polygon Portal to deposit and swap tokens between the Polygon zkEVM chain (or the Cardona zkEVM testnet) and other chains. dApp projects are divided into two parts: Using Docker. Welcome to the Polygon Knowledge Layer! This documentation is built using the Material theme for MkDocs . Learn how to build and deploy dApps, launch ZK rollups and validiums as Layer 2s on Ethereum, spin up nodes, and find out about the latest in zero-knowledge research. , transaction fees. Plonky was Polygon’s original implementation of a zk-SNARK computational cryptographic library based on Plonk with some customizations. It allows you to run Ethereum dApps in your browser without running a full Ethereum node. This document provides examples of token mappings on the Polygon PoS mainnet and Amoy testnet. Heimdall is the heart of the Polygon PoS network. We follow the Soulbound NFT tutorial from this video . To fork Polygon zkEVM, for example, run the following command: dapp-launchpad dev -n polygonZkevm To fork at a particular block number run the command including the optional flag -b : Validators on the Heimdall layer pickup the StateSynced event and pass it on to the Bor layer. The signer wallet is an address that is used for signing Heimdall blocks, checkpoints, and other signing-related activities. This document provides details of the Etrog upgrade, which is Polygon zkEVM’s upgrade that succeeds the Dragonfruit upgrade. Heimdall¶. Available configurations are - Setup local zkNode. Due to this, there is a change in how the transaction object is formed when sending transactions on Polygon. The unified UI comes with a comprehensive dashboard that can be used by connecting your wallet via popular tools such as MetaMask, Coinbase, Bitski, Venly, WalletConnect, and more. validiums¶. In terms of space, for a full node you’ll need from 2. Bor. We use cookies to recognize your repeated visits and preferences, as well as to measure the effectiveness of our documentation and whether users find what they're searching for. Run an access node. Nodes on Polygon are therefore designed with a two-layer implementation represented by Bor (the block producer layer) and Heimdall (the validator layer). It enables developers to acquire free POL/ETH test tokens on the PoS Amoy and zkEVM Cardona testnets. The first line pragma solidity ^0. MetaMask is a crypto wallet for web browsers and mobile devices that interacts with the Ethereum blockchain. The Transactions subsection provides information about the EIP-1559 as it applies to how gas estimations and costs of transactions work on Polygon PoS. Heimdall and Bor. Getting started. Proving and verification of transactions in Polygon zkEVM are all handled by a zero-knowledge prover component called the zkProver. Although the Dragonfruit upgrade had some advantages over previous zkEVM versions, it has its own pain points. Downloading and using client snapshots¶. Network details ¶ Mumbai testnet deprecated A full zk-rollup schema requires on-chain publication of both the transaction data (which users need to reconstruct the full state) and the validity proofs (zero-knowledge proofs). Polygon Faucet¶. Understanding these ports is crucial for network configuration and effective communication between nodes. Layer 2 (L2) blockchains are scaling solutions, typically built on top of Ethereum (L1) that are designed to increase transaction throughput without sacrificing decentralization or security. Heimdall’s bor module is responsible for managing span intervals and coordinating interactions with the Bor chain. Specifically, the following changes are being proposed: Bridging POL to Polygon PoS: if you bridge POL tokens to Polygon PoS, you will receive an equal amount of native tokens (POL) on Polygon PoS. To begin, ensure that your node environment meets the prerequisites outlined here. System requirements¶. The general configuration for running a Polygon full node is to have at least 4 CPUs/cores and 16 GB of RAM. By design, it is being integrated into the core operations of major Polygon products and applications in the ecosystem. ChainList¶ Depending on the network profile that you want to add to your MetaMask wallet, use one of the following links to navigate to the respective ChainList page. You can use the same methods to add Polygon zkEVM to your MetaMask wallet. This section of the documentation contains guides on how to connect wallets to the Polygon zkEVM network, deploy new or existing Ethereum smart contracts, and bridge assets between Polygon zkEVM and Ethereum. Additional resources¶ Here are some additional developer resources. 10 specifies that the source code is for a Solidity version greater than 0. Visit the Polygon Portal documentation page for guides on how to connect to and operate the Polygon Portal website The Polygon CDK Kurtosis package allows you to easily customize and instantiate all the components of a CDK chain. It uses the Kurtosis tool to orchestrate the setup of the chain components in Docker containers, with logic defined in Starlark scripts (a Python dialect) which define the step-by-step process of setting up the chain. Polygon Portal is an integrated UI platform that serves as a one-stop solution for asset management and token operations such as swapping and bridging. Polygon zkEVM overview Take a global view of the Polygon zkEVM network. Etrog upgrade¶. Check out the all the QRNG Providers here. 5 to 5 terabytes of SSD (or faster) storage. This guide provides a detailed list of default ports used across Polygon nodes, including Bor and Heimdall. The Portal can be used to perform a variety of tasks, such as: Change the value of Prometheus to true; Set the max_open_connections value to 100; Make sure you keep the proper formatting when you make the changes above. Transactions. The Heimdall doesn’t look in sync and hence it won’t have data on all the things that Bor would require. You can try QRNG on the Polygon and Polygon zkEVM for free. CDK chains have full control over how gas fees are set for users, including what token to use for the native gas fees of the L2 chain, which is set to ETH by default. Set up the environment ¶ Polygon PoS is an EVM-compatible, proof-of-stake sidechain for Ethereum, with high throughput and low costs. This guide provides an index of network details for the Polygon Amoy testnet and Polygon PoS mainnet, including their associated RPC and node endpoints. Introduction. This consensus model is characterized by predefined block producers who collectively participate in a voting process to appoint new producers, taking turns in block generation. Checkpoints are vital components of the Polygon network, representing snapshots of the Bor chain state. Overview¶. Be sure to select Layer 2 on the Filter menu on the left side of the page to list wallets that are compatible with Polygon networks. It is the Polygon zkEVM’s preferred framework, and therefore used in the zkEVM as a default for deploying and automatically verifying smart contracts. There is often a need to access information from the outside world that is relevant to the contractual agreement. Gas fees¶. However, given Ethereum’s current framework, publishing callback data to L1 incurs high gas fees, complicating the decision between opting for a full zk-rollup or Get started. It performs the following functions: Manages validators. But smart contracts can’t access data from outside of their blockchain network. Plonky 2 & 3 are active research efforts into the development of libraries containing performant cryptographic functions for use in zero-knowledge proof systems. This guide provides a curated list of common commands and Polygon-specific operations essential for node operators. More specifically, they often differ in what they do with the transaction data (i. Before committing new L2 state roots to the consensus contract, verification is essential. For the Polygon PoS Proof of Security based consensus, all the \(2/3+1\) proof verification and handling of staking, rewards are executed on the Ethereum smart contract. Owner and signer wallets¶. The Polygon Proof-of-Stake (PoS) network is designed to address scalability challenges within the Ethereum ecosystem. 5. Bor is an integral component of the Polygon network that operates based on principles derived from the Clique consensus protocol, detailed in EIP-225. Welcome to the technical documentation and knowledge resources for Polygon protocols and scaling technologies. Specifically, it determines when a new span can be proposed on Heimdall based on the current block number n and the current span span. The whole design follows this philosophy of doing less on the Mainnet contract. It sets up and runs the following components: Torus is a user-friendly, secure, and non-custodial key management system for decentralized apps. Understand the CDK A high-level overview of the CDK, its features and benefits. Checkpoints. Polygon portal¶ The Polygon Portal is a comprehensive solution for account management on Polygon.

Heimdall layer: A set of proof-of-stake Heimdall nodes running in parallel to the Ethereum mainnet, monitoring the set of staking contracts deployed on the Ethereum mainnet, and committing the Polygon PoS network checkpoints to the Ethereum mainnet. , pragma once). Polygon zkEVM supports a majority of Ethereum EIPs, precompiles, and opcodes. Layer 2s can differ in how they interact with Ethereum. the information about transactions that occurred on the L2). The majority of developers use a node provider, or a third-party external service that receives node requests and returns responses for you automatically. These logs in Bor mean that it cannot connect to Heimdall. dApp Launchpad is an automated CLI tool for initializing, creating, and deploying a fully-integrated web3 dApp project. Overview - Polygon Knowledge Layer. EIP-1559. A wallet and an application supporting this protocol will enable a secure link through a shared key between any two peers. This document is a guide on how to deploy a smart contract on the Polygon zkEVM network using Hardhat. The receiver contract inherits IStateReceiver , and custom logic sits inside onStateReceive function. Rollups vs. The logic within the consensus contract verifies the zero-knowledge proofs, thereby endowing the zkEVM with the security of Layer 1. Cookie consent. Get started with PoS Get started with building on Polygon PoS. Polygon zkEVM is a Layer 2 network of the Ethereum Virtual Machine (EVM), a zero-knowledge (ZK) rollup scaling solution. We also publish resources necessary for learning about and contributing to Polygon technologies. This is the flow required from dapps / users to work with state-sync: Once the wallet is connected, the next step is to bridge crypto assets from Ethereum to zkEVM. These instructions are for running a full Node, but they can be adapted for running sentry nodes and validators as well. . WalletConnect is an open protocol - not a wallet - built to create a communication link between dApps and wallets. Click here to read more about API3 QRNG. In particular, and on the execution client side, it delineates on snapshots and state syncing, network configurations, and frequently used commands when running PoS nodes. While L2s are their own chains, they are considered “extensions” of Ethereum. Transaction option¶. Polygon zkEVM is to Ethereum a Layer 2 network and a scalability solution utilizing zero-knowledge technology to provide validation and fast finality of off-chain transactions. Polygon CDK provides the components necessary to build a layer 2 blockchain that is secure, scalable, and interoperable with other chains. In this guide, we demonstrate how to deploy an ERC-721 token contract on the Polygon zkEVM network using Foundry. Our goal is to establish a high-quality, curated, and comprehensive \"source of truth\" for technical knowledge surrounding Polygon's main technology. These batches are submitted to the L1, where their integrity is proved and verified before being included in the L1 state. The London hard fork introduced a new EIP that modifies how gas estimation and costs work for transactions on Polygon. The procedure that makes it possible is: Validators on the Heimdall layer are listening for a particular event — StateSynced from a sender contract, as soon as the event is picked, the data that was passed in the event is written on the receiver contract. The Polygon Knowledge Layer consists of technical documentation that developers need for building with Polygon protocols, products, and services. These configurations can be passed as parameters. Apr 22, 2024 · The Polygon Ecosystem Token (POL) is the new native token of the Polygon ecosystem. Jan 24, 2024 · As a central component of Polygon 2. e. There are some configurable options that are available for all API’s. And if the proof is correct, the verifier is convinced that the computation expressed as the Arithmetic circuit is valid, but learns nothing about the wires’ assigned values. The Polygon team distributes official Docker images which can be used to run nodes on the Polygon PoS mainnet. It is a scaling-solution to Ethereum as it rolls up many transactions into one batch. The difference between EVM-compatibility and EVM-equivalence is that; Solutions that are compatible support most of the existing applications, but sometimes with code changes. Polygon Chain Development Kit (CDK) is a modular, open-source blockchain stack for developers launching sovereign L2 chains powered by zero-knowledge (ZK) proofs. 0, the AggLayer will use ZK proofs to create a seamless, aggregated environment that feels like a single chain–even as each chain in the ecosystem remains sovereign. It operates as an EVM-compatible Layer-2 (L2) scaling solution for Ethereum, enhancing its throughput while also significantly bringing down gas costs, i. Token mapping Want to get a custom token mapped to Polygon PoS so it can be bridged over? In the context of ZK-proof protocols, a prover can use an Arithmetic circuit to prove knowledge of a valid assignment to all wires of the circuit. The design paradigm at Polygon has shifted to developing a zero-knowledge virtual machine that emulates the Ethereum Virtual Machine (EVM). It queries the RPC for eth_feeHistory and fetches the 10 th , 25 th , and 50 th percentiles of priority fees for transactions in each of the last 15 blocks. This is an important milestone for Polygon PoS’s upgrade to a ZK secured chain. g. This wallet’s private key is on the validator node for signing purposes. Feb 8, 2024 · The Polygon zkEVM prover now supports a Type 1 mode, allowing any existing EVM chain to become a ZK Layer 2 (L2) and connect to the AggLayer. rhtfos asnz vznxz fcuquand ior iygelr mmfup vbl xwnlws ewcw
