One of the most important updates of Polkadot 2.0 is Core time. Dot’s architecture is divided into two chains: one is the relay chain (relay chain) responsible for maintaining security and cross-chain information; the other is parachains (parachains) ) 50 items in total, used for application. The dot mania during the last bull market was mainly caused by slot auctions. The slot auction is to determine which projects can use slots and obtain the right to use dot parachain slot resources through everyone's pledge vote. At that time, nearly 100 million dots were locked in the first round of slot auction. That is, the cost of using the slot is very high. In order to solve this problem, the big upgrade "core time" of dot2.0 appeared. The resource provision is no longer in the form of expensive two-year slots, but replaced by a core time mechanism. You can purchase it at a cheaper price for flexible use in a shorter time or with smaller performance.
To put it simply, the original slot auction was like buying a supercomputer with a huge sum of money, and the core time was that the supercomputer was provided by AWS.
It is up to developers and users to decide what kind of plan they want to buy, and even if they buy too much, they can transfer the core time again. Maximize resource utilization.
Buying Dot now is like buying Amazon in 2002
