🚀 Latest news on Polkadot! Gavin Wood announced at the Polkadot Fellowship meeting that JAM Grey Paper v0.4 has a key update - "Ordered Accumulation" has been officially merged, which is the last major core protocol pull request before the release of v1.0. JAM breaks the "sharding island" through a distributed decentralized data lake to achieve efficient computing. Next, v0.5 will optimize performance and upgrade PVM to 64 bits. Elastic expansion is expected to be launched early next year, and Polkadot 2.0 will be fully launched soon! 💥 #区块链#Polkadot#JAM
