Polygon Miden: Core Architectural Concepts and Transaction Models
Polygon Miden: Core Architectural Concepts and Transaction Models
Polygon Miden is a novel ZK rollup optimized for privacy, parallelization, and client-side proving capabilities. The Miden Node, which has completed a test version, functions by exposing RPC endpoints, verifying user-generated proofs, producing blocks, and updating the state. Transactions in Miden facilitate account state changes and are performed against a single account, enabling parallel execution and asynchronicity. Users have the option to store data publicly or privately, as well as choose who generates the ZK proof. Off-chain storage and client-side proofs enhance privacy and scalability. Miden aims for absolute privacy while addressing the possibility of an experienced observer gaining information.

This week, the researchers and engineers building Polygon Miden completed a test version of the node that will manage the state of the rollup. This is what the Miden Node does and how it functions for user-generated state transitions. The basic functions of this first version of
To achieve parallel execution in Polygon Miden, researchers had to look beyond account-based systems like Ethereum to UTXO-based systems like Bitcoin and Zcash. The end result is a transaction model distinct among ZK rollups.
In the latest installment of @AvailProject's whiteboard series, @bobbinth and @prabalbanerjee dive into core architectural concepts of Polygon Miden and the principles shaping the unique ZK rollup’s development. Full episode here: youtu.be/QuLhkaszLtA Polygon Miden,
The state model in Polygon Miden gives users the option to store their account and note data in two ways: 1. Public and on-chain 2. Private and off-chain These options create different degrees of privacy. With public storage, the data is on-chain and visible to everyone.
Polygon Announces 33 Grant Recipients for Season 2 Direct Track
Polygon has selected 33 projects as recipients for their Community Grants Program Season 2 Direct Track. These projects will receive support to develop solutions within the Polygon ecosystem. The grant program, which opened applications in January 2025 with a 35M POL allocation, focused on several key areas: - AI agents - Apps and infrastructure - DePIN (Decentralized Physical Infrastructure Networks) - Memecoin projects Independent Grant Administrators including @ai16zdao, @crossmint, @iotex_io, @thriveprotocol, and @gitcoin helped oversee the selection process. Individual project spotlights will be featured in the coming weeks.
Morpho and Gelato Launch Seamless DeFi Lending on Polygon
Morpho has partnered with Gelato to launch a new crypto-backed lending service on Polygon. The integration offers a frictionless borrowing experience with several key features: - No custody requirements - No transaction signing - Zero gas fees - No credit checks needed The service targets exchanges, wallets, custodians, and apps looking to embed lending functionality. Implementation takes hours rather than months using Gelato's Smart Wallet SDK, which eliminates common Web3 friction points like wallet extensions and seed phrases.

Agglayer v0.3 Launches with Pessimistic Proofs
Agglayer has released version 0.3, building on their successful v0.2 testnet launch. The protocol introduces **pessimistic proofs** - a groundbreaking implementation for unifying EVM chains. Key features: - First-ever pessimistic proof system for cross-chain communication - Cryptographic safety guarantees for cross-chain balances - Secure message passing between different blockchain stacks The project has progressed from devnet through testnet, reaching this significant mainnet milestone. Development can be tracked at [Agglayer GitHub](https://github.com/AggLayer).
Agglayer v0.3 Upgrade Enables Non-CDK Chain Integration
Agglayer announces v0.3 upgrade, marking a significant expansion in cross-chain compatibility. The update will enable non-CDK chains to join the network, with Polygon PoS integration planned for Q3. Key improvements: - Enhanced pessimistic proof security - New chain-specific execution proof verification - Sub-10 second interoperability target - Expanded balance verification system The upgrade represents a crucial step toward chain-agnostic infrastructure, focusing on secure and rapid cross-chain communication. This development builds on February's pessimistic proof implementation, further strengthening the protocol's security framework.
