Polkadot 2.0 is about to be launched on @ Polkadot mainnet This is the biggest update in recent years, in addition to the JAM that has been completed Polkadot 2.0 Definition: Polkadot is a multi-core decentralized computer network that provides high resilience and verifiable computing power through virtual cores. A chain that runs continuously in parallel on different virtual cores is called a Rollup chain. Core features: -Asynchronous support: allows pipeline operations to achieve a more efficient Rollup system, providing higher throughput for Rollup without compromising security. -Coretime: allows flexible allocation of cores for execution on Polkadot distributed computers. -Elastic scaling: allows the same Rollup chain to use multiple cores simultaneously to increase throughput. Compared to Polkadot 1.0, which used slot auctions (the most criticized mechanism), 2.0 abandoned the slot auction model and instead adopted [coretime] to create an agile marketplace. In this market, Coretime will become a commodity that can be tokenized, sold, and traded. Rollup chains can be purchased: -Batch Coretime: A standard way to purchase core time at a fixed price and for a fixed period through the Coretime system chain, with predictable renewal prices. -On demand Coretime Time: By continuously selling and purchasing Coretime on demand, use it immediately at spot prices In version 1.0, each chain could only use one coretime, but after version 2.0, coretime can be flexibly used as needed, as shown in the following figure: A few months ago, 2.0 was launched on KSM and will soon be available on the Polkadot mainnet
