According to BlockBeats, during the latest Polkadot Fellowship meeting on October 21, Dr. Gavin Wood announced a significant update to the JAM Gray Paper v0.4, with the formal integration of 'Ordered Accumulation.' This marks the final major core protocol pull request before the release of v1.0.

JAM aims to create a distributed decentralized data lake, enabling work packages to efficiently modify and reuse data, thereby overcoming 'shard islands' and achieving coherent computation. This model surpasses the capabilities of both the Polkadot relay chain and Ethereum. The 'Ordered Accumulation' feature ensures that cross-block work packages are processed sequentially, particularly when one work package depends on the output data of a previous one, thus ensuring efficient and reliable computation.

Additionally, Fellowship member Andrei Sandu shared that Elastic Scaling is set to go live on Polkadot in January or February next year. Elastic Scaling is the final component of the Polkadot 2.0 launch, indicating that Polkadot 2.0 is expected to be fully operational by January or February next year.
