The most important updates to Polkadot in May
Polkadot has always been a high-quality and high-quality value investment target with very hard core technology but not good at publicity and hype.
In May Polkadot quietly hit the road with a super update on the Rococo testnet:
Dot, which claims to produce blocks in 6 seconds, actually took about 12 seconds in the previous system from the time the parachain produced the block to being included in the relay chain. The previous design was Synchronous Backing. In these 12 seconds, only one block takes 0.5 seconds to execute, with 5.5 seconds left to complete backing and gossip, and nearly 6 seconds to complete inclusion.
Asynchronous backing (asynchronous support) system does not have to wait 12 seconds to process the next block. Instead, multiple blocks are multi-processed in the same 12 seconds without synchronization. The disadvantage is the time to create and deblock. It may be stretched to about 18 seconds, but the rest is pure benefit. 1. The proportion of parallel chain block generation time has increased (the amount of data processed has increased significantly from 0.5 seconds to 2 seconds) 2. Multiple blocks are processed simultaneously, allowing the average block generation to reach 6 seconds (time doubled) 3. Parallel chains can choose different and not the latest relay chain parent blocks to fill blocks and make full use of the block space. The above three points can increase the tps of the overall dot ecosystem to 100,000 to 1,000,000.
This big update will be released on kusuma at the end of this year, and it will be deployed on Polkadot at the beginning of next year. Don’t be fooled.
