What kind of Technology Solution is Substrate? What is its relationship with Polkadot?
In the past, blockchain can also start a chain in a few minutes, but only parameters can be changed simply, such as BTC or ETH to change the amount of currency issued, so the short time is not the point. Gavin demonstrated a new game chain. This kind of business flexibility and complexity is times of magnitude modified in the past.
Compared with the previous smart contract chain, which can deploy a contract within a few minutes, the development flexibility of the runtime module now will be much higher than that of the contract, which is also one of the differences. So in the past, the chain is rigid. It’s not easy to expand the bottom layer and write the upper layer contract at most. Polkadot’s support for paralchains is not an isomorphic contract level, but a heterogeneous underlying technology level, which can also be derived from the contract level.
So substrate is more like some website development frameworks, such as Rails or PHP, which can create a blog website in a few minutes, but there will be many things that need to be customized and optimized in the future. The level involved in chain building is not simply to write out a module, but also includes a unique economic system, web and mobile interactive interface. Homogenization of small changes will not be competitive, real large-scale applications still need to do a lot of work on the substrate.
