Plasma

It is one of solutions to solve the problem of scalability of Ethereum. Plasma has made more state updates per second to make it more scalable. And it is a proposed solution for dApp's smart contracts related to the field of servicing financial services and data worldwide. The plasma has an existing root chain and a child chain as a sub-chain. In the plasma structure, a number of blockchains are connected in a tree structure as follows.

In the plasma, the hash value of the block header of the child chain is gathered to become the parent node, and the hash value of the node becomes the next higher node, and finally, a lot of block information of the lower chains is included in the root chain, It will be reflected in the main chain of Ethereum.

The operation structure of the plasma can be found in Plasma White Paper.
