- JAM, Polkadot’s biggest upgrade ever, has been approved.
- JAM is designed to replace Polkadot’s central chain with a new system.
- A complete transition is planned, but will not disrupt current DOT holders or functions.
Polkadot, a leading blockchain platform known for its multi-chain architecture, is about to undergo its biggest upgrade yet. The Join Accumulate Machine (JAM) overhaul, proposed by Polkadot founder Gavin Wood, aims to revolutionize the core functionality of the network and open up new possibilities for developers and users alike.
What is JAM?
At the core of JAM is a fundamental change in the design of Polkadot’s central chain, the Relay Chain. JAM proposes to replace relay chains with a more streamlined, modular system that allows developers to build various services directly on top of them. This is a departure from the current system where developers must compete for parachain slots through auctions.
How does it work?
JAM’s technology base includes a supercomputer called the Polkadot Virtual Machine (PVM), powered by the RISC-V architecture. This transition is expected to improve efficiency and performance in the current WebAssembly framework.
The JAM service integrates seamlessly with the rest of the Polkadot ecosystem, enabling seamless communication and data exchange between various applications.
How does JAM change Polkadot?
The JAM upgrade will significantly change the Polkadot environment. JAM removes the barrier to entry for developers by eliminating the need for expensive parachain auctions. Now anyone can build services and smart contracts on the network, fueling innovation and a wide range of applications.
Unlike the current parachain-centric approach, JAM offers a more diverse environment. Developers can choose between building parachains or services depending on their specific requirements.
Existing parachains will continue to function, but they are no longer the only development option. JAM opens the door to a wider range of services and applications to be deployed on the network.
When will JAM be released?
A production-ready JAM will likely be several years away. Unlike previous updates to Polkadot, JAM will not be introduced incrementally. Migration happens all at once. The actual conversion will not affect those who wish to hold or trade DOT tokens. Unlike forks in other blockchains, no new coins are created.
JAM is not a hard fork. This means that the functionality of existing parachains will not be affected. However, parachains are just one of many products that can run on the JAM Chain. Web3 Foundation assures users that parachains will still be important even after JAM.
On the flip side
- JAM’s complex PVM systems and services may result in security vulnerabilities that are difficult to detect and remediate.
- JAM removes parachain auction barriers but centralizes authority among core JAM service providers, raising concerns about centralization.
- Due to the extensive overhaul of JAM, it may face development delays and technical issues, potentially delaying its release.
Why This Matters
By removing parachain auction barriers and enabling a wider range of services, JAM has the potential to transform Polkadot into a more comprehensive and dynamic blockchain ecosystem, fostering innovation and attracting a wider range of developers and users, could have a big impact on its future. The technology itself.
