Polygon Labs developers introduced Polygon Miden, a ZK-optimized rollup that was designed to complement Ethereum’s feature set, with a focus on privacy.
Polygon has set out to become the value layer of the Internet, and has introduced a number of innovations in recent months aimed at achieving this goal.
Recently, Polygon Labs developers published several articles about Polygon Miden, a new rollup written in Rust that was created to innovate and enable new functionalities on the network.
With its innovative architecture, Polygon Miden will give developers and builders the ability to create private decentralized applications with high performance, security, and scalability, the developers said.
Polygon Miden: Scalability, Security and Privacy
In the first post on Polygon Miden, Polygon Labs developers explain that the new rollup will expand Ethereum's features on three main axes, Scalability, to maximise security and your enjoyment. y privacy, which are essential to bringing the blockchain to millions of new users.
Verification without re-execution
Regarding scalability, they highlighted that, by using zero-knowledge or ZK technology, Polygon Miden offers the possibility of verify that transactions were executed correctly without the need to re-execute on the chain, which reduces processing power consumption and improves speed, making the network more efficient and accessible.
This feature also allows users to execute smart contracts locally, i.e. from their devices, and then send ZK proofs to the network so that operators can validate them and update the network state accordingly, more quickly.
Asynchronous execution and new smart contract languages
Regarding security, Polygon developers explained that at Miden they will maintain a risk-reduction approach, in order to make blockchain technology and crypto assets easier to use for everyone. Thus, to ensure security, Polygon Miden makes use of the account abstraction.
Polygon Miden also uses a model of asynchronous execution, which makes it possible to create recoverable transactions.
According to the developers, this execution model is implemented to secure assets, so that they are always safe and easy to manage, even if users lose their private key or sign a transaction to the wrong address.
On the other hand, the network stores fungible and non-fungible assets in accounts, rather than global token contracts, in order to minimize the risk of exploits or hacks. It also supports new programming languages such as Move and Sway, which allow the development of smart contracts to be more robust and secure.
Privacy at the heart of Polygon Miden's design
Polygon Labs developers defend privacy as a fundamental right for everyone. That's why Polygon Miden allows the Local execution of smart contracts, in order to maintain privacy.
Polygon has called these contracts “Expressive Private Smart Contracts,” which are private smart contracts that allow creators to preserve the privacy of their code but can fully interact with regular or public smart contracts.
Polygon Miden’s architecture opens up a new world of possibilities for decentralized applications that require privacy as a fundamental factor. For example, according to the developers, Polygon Miden is perfect for financial institutions that need to build their business logic and execute their business processes, keeping their information confidential and hidden from competitors but visible and transparent to auditors.
On the other hand, the network's developers recognize that privacy is a complex issue that can take on various nuances, so it will be enabled on Polygon Miden at different levels and gradually.
Some unique features
One of the features that makes Polygon Miden a unique rollup package is that it is Turing complete, allowing for complex program logic. It also supports procedures and multiple isolated execution contexts, which improve programming.
Polygon Miden also supports u32 operations and cryptographic operations using the virtual machine's native hash function.
In the latest post about Polygon Miden, the developers explained how privacy on blockchains goes hand in hand with scalability, an essential feature for onboarding millions of new users efficiently.
