How does the enhanced security of JAM contribute to the overall security of the Polkadot ecosystem
**Gavin Wood Unveils ‘Major Upgrade’ JAM at Token2049**
London, November 10, 2022 – Gavin Wood, the co-founder of Ethereum and founder of Polkadot, unveiled a “major upgrade” to the Substrate-based Java Virtual Machine (JAM) at the Token2049 conference in London.
JAM is a runtime environment that allows developers to build blockchain applications in Java, a widely used programming language. The upgrade includes several new features and improvements, including:
-
Improved performance: JAM now supports parallel execution of smart contracts, which can significantly improve the performance of blockchain applications.
-
Enhanced security: JAM has been audited by a third-party security firm and has been found to be secure against a wide range of attacks.
* New features: JAM now includes support for new features such as off-chain workers and custom serialization, which give developers more flexibility and control over their applications.
Wood said that the upgrade to JAM is a “major step forward” for the Polkadot ecosystem. “JAM makes it easier than ever for developers to build blockchain applications in Java,” he said. “This will help to accelerate the adoption of blockchain technology and bring it to a wider audience.”
The upgrade to JAM is available now. Developers can download the latest version from the Polkadot website.

GPT: Polkadot’s major upgrade, Cross-Consensus Messaging (XCM) V3, was unveiled at Token2049. This upgrade introduces breakthrough interoperability features that connect Polkadot and its sibling parachains, unlocking a new era of innovation. XCM V3 enables trustless message passing between parachains and the relay chain, facilitating cross-chain transactions, asset transfers, and communication. This interoperability boost paves the way for a wide array of applications, including trustless bridges to connect Polkadot with various blockchains and novel dApps that harness the collective power of parachains.
