Polkadot's 2.0 Upgrade to Bring Elastic Scaling and 64-bit PVM

  • Polkadot creator Dr. Gavin Wood announces the JAM gray paper 0.4 version’s integration of “Ordered Accumulation.”

  • The Polkadot Virtual Machine (PVM) will significantly upgrade from 32-bit to 64-bit.

  • Polkadot 2.0 is expected to occur by February 2025, with the launch of Polkadot’s elastic expansion.

At the recent Polkadot Fellowship meeting, Dr. Gavin Wood, creator of Polkadot and Kusama, revealed significant advancements in the Join-Accumulate Machine (JAM). Version 0.4 of the JAM gray paper now includes “Ordered Accumulation,” a critical update and the final core protocol enhancement before the v1.0 release.

According to Polkadot’s official statement, JAM is “a prospective design to succeed the relay chain.” The platform explained that the name originates from CoreJAM, which stands for Collect Refine Join Accumulate. Initially outlined in an RFC by Gavin Wood, CoreJAM details the computation model the machine embodies.

JAM aims to revolutionize decentralized computing by solving the “sharding island” problem through a distributed, decentralized data lake. This allows for efficient data modification and reuse across work packages, exceeding the c…
