1. Polygon PoS

Scale and Power

Polygon PoS is a Layer 2 scaling solution that achieves unprecedented transaction speed and cost savings by utilizing side-chains for transaction processing. At the same time, POS ensures asset security using the robust Plasma bridging framework and a decentralized network of Proof-of-Stake (PoS) validators.


  • Intuitive, efficient bridging, deposit, and withdrawals
  • Transaction speeds of up to 65,000 tx/s mean exponentially faster performance than Ethereum at 15 tx/s
  • Non-custodial architecture means users have control of their keys
  • Rely on the shared security of Ethereum with the benefit of Polygon’s speed


  • Compatible with major ERC standards
  • Secured by validators and checkpoints submitted to Ethereum
  • Minimal downtime over the course of 1.3B recorded transactions
  • A powerful and engaged community driving adoption and user engagement


  • Full EVM compatibility means deploying your smart contracts directly on the Polygon chain
  • A composable blockchain means you’ve got a wide variety of apps to build on
  • Easy transfer to and from Polygon and Ethereum
  • Easy-to-use wallet on web and mobile


  • Fractional costs per transaction powered by Polygon’s proof-of-stake architecture
  • Approximately ~10,000x lower costs per transaction than Ethereum
  • More predictable gas fees and deflationary token economics with EIP 1559 token burns

Built for flexibility and security

Polygon’s scalable proof-of-stake architecture complements Ethereum’s decentralized security, ensuring you have the ability to create apps that can appeal to the masses while maintaining the power of decentralization.

3. Polygon Avail

Scalable data availability focused blockchain

A core component of the modular blockchain movement coming in the near future. Targeted towards off-chain scaling solutions and standalone chains.

Modular Blockchain Paradigm

Avail aims to facilitate a complete change in how we approach the design of blockchain systems. Avail enables modular chain design where various execution environments can use Avail for data ordering and availability. Avail is agnostic to the execution layer, which can be the standalone chains or off-chain scaling solutions that use Avail. The applications hosted on these execution layers enjoy the full security of Avail.

Decoupling execution from data availability

Off-chain scaling solutions can unlock their full potential by offloading data availability to Avail. Standalone chains can bootstrap validator security by using Avail for data availability.

Data Redundancy

  • Every piece of data is erasure-coded using polynomial interpolation
  • Redundancy makes it harder to suppress data
  • Light clients get ~100% confidence in data availability by performing a constant number of queries

Low Resource Requirement

  • Hosting a full node isn’t needed to get an availability guarantee
  • Application clients can query data only relevant to application of their interest, without downloading the entire block
  • System scales up as the number of users increases, increasing the availability of data

Polynomial Commitments

  • Avail avoids fraud proofs using KZG polynomial commitments
  • The data of each block is committed to the headers
  • Light clients sample data and verify using commitment openings
  • Batch openings help us optimize verification and proof size

4. Polygon Hermez

Scalable payments, with Zero-Knowledge Rollups.

Hermez is an open-source zk-Rollup optimised for secure, low-cost, and usable token transfers on the wings of Ethereum.

Ethereum Scalability and ZK-Rollups

Hermez zk-rollup is a layer 2 construction on top of Ethereum that solves its scalability through mass transfer processing rolled into a single transaction. The “zero-knowledge proof” (ZK) technology is used to present and publicly record the validity and correctness of the rolled transfers processed on the Ethereum blockchain. By storing just the proof and the compressed data of a batch of transfers, the efficiency and the throughput of the network is multiplied.

Powerful and trustless

  • Ethereum-level security guaranteed by zk-SNARKs
  • High throughput of 2000 TPS
  • Non-custodial architecture
  • Full ownership and control of assets (censorship-resistant)
  • Data availability on Ethereum mainnet

The only decentralized zk-rollup

  • Fully open-source and community-driven
  • Seamless integration with Hermez REST API
  • Permissionless network of coordinators
  • Decentralised auction model with validation reward token
  • Strategy towards governance minimisation

Token transfers simplified

  • Simple web and mobile app wallet
  • Low-cost token transfer
  • Atomic swaps
  • Fees payable in a single currency
  • Fast capital-efficient exit (withdrawal) in a few minutes

Layer 2 scalability solution

Computational integrity and on-chain data availability are guaranteed by zero-knowledge proof technology while preserving the public blockchain properties of Ethereum.

5. Polygon Miden

General purpose zk-rollup

Polygon Miden is a STARK-based, Zero-Knowledge rollup with support for arbitrary smart contracts

STARK-based zk-rollup

Polygon Miden is a Layer 2 scaling solution for Ethereum. Miden relies on zero-knowledge technology (zk-STARKs) to “roll-up” thousands of layer 2 transactions into a single Ethereum transaction, thus, increasing throughput and reducing transaction fees. At the heart of Polygon Miden is Miden VM: a Turing-complete STARK-based virtual machine that provides a level of safety and supports advanced features currently not available on Ethereum.

Secure and scalable

  • Ethereum-level security provided by zk-STARKs
  • Transparent (no trusted setup) and post-quantum secure
  • High throughput of 1,000+ TPS before sharding and 10,000+ TPS after sharding
  • Low transaction fees: over 100x lower than fees on Ethereum

Safely programmable

  • Arbitrary smart contracts are written in Solidity and other languages
  • Account abstractions and other features not yet available on Ethereum
  • Simpler formal verification of contracts due to safe VM architecture
  • Clear roadmap to privacy-preserving smart contracts

Open and permissionless

  • Fully open-source and community-driven development
  • Decentralized and permissionless network
  • Non-custodial architecture (full ownership of assets)
  • Censorship-resistant

6. Polygon Nightfall

A privacy-focused Rollup for Enterprises

Polygon Nightfall is an Optimistic Rollup designed to lower the cost of privately transferring ERC20, ERC721, and ERC1155 tokens. It uses an Optimistic Rollup to reduce transaction fees and zero-knowledge proofs for privacy. The Optimistic Rollup contracts are deployed on Ethereum (Layer 1). Proposers roll-up transactions into blocks and submit them to the Optimistic contracts. Challengers submit fraud proofs for any invalid block to the same contracts. All the information required to perform a private transfer exists with clients and does not rely on any off-chain third party.

Optimistic Rollups with Zero-Knowledge

Polygon Nightfall is an Optimistic Rollup aimed to lower the transaction cost of ERC20, ERC721, and ERC1155 token private transfers. It uses Optimistic Rollup for lowering the costs and the privacy is attained by leveraging zero-knowledge proofs. The optimistic rollup contracts are deployed on Ethereum (layer 1). Proposers will roll up transactions into blocks and submit them to the Optimistic contracts. Challengers will submit fraud proofs for any invalid block to the same contracts. All the information required to perform a private transfer exists with clients and does not rely on any off-chain third party.

7. Polygon Zero 

World’s most performant ZK L2

Polygon Zero uses the speed of Plonky2 to enable a more scalable and decentralized ZK L2. It offers both rollup and validium modes, giving users access to higher throughput and lower fees.

Fast ZK proofs validated on Ethereum

Polygon Zero is a Layer 2 scaling solution for Ethereum. What separates Polygon Zero from other ZK scaling solutions is the power of Plonky2, our groundbreaking prover system, which generates ZK proofs faster than any other existing tech.
