Odaily News At the latest Polkadot Fellowship meeting, Gavin Wood said that JAM Grey Paper v0.4 ushered in a key update - "Ordered Accumulation" was officially merged, which was the last major core protocol pull request before the release of v1.0. JAM creates a distributed decentralized data lake, enabling work packages to efficiently modify and reuse data, breaking the "sharding islands" and achieving coherent computing, far exceeding the models of Polkadot relay chains and Ethereum. And "Ordered Accumulation" ensures that work packages across blocks are processed in sequence, especially when a work package depends on the output data of the previous one, thereby achieving efficient and reliable computing. Next, v0.5 also lists some minor changes, such as adding fields and optimizing the order of operations to improve performance. One of the updates is to upgrade PVM from 32 bits to 64 bits, bringing stronger performance and data processing capabilities. In addition, Fellowship member Andrei Sandu also shared that elastic expansion will be launched on Polkadot in January or February next year. Elastic expansion is the last part of the Polkadot 2.0 launch, which means that Polkadot 2.0 is expected to be fully launched in January or February next year. (PolkaWorld)
