An innovative Ethereum-based off-the-main-chain solution to better integrate the network for better transactions.
Plasma is the term used in the Ethereum community to describe an innovative solution meant for scaling the network. The main idea is that the Ethereum network can run more efficiently if it has smaller chains to run some of its operations. As such, the network will assume the form of a mega cell with other cells empowering it, thereby scaling transaction processing. The ‘glue’ for this interaction process across the main network and the other chains is plasma.
Plasma has not been implemented. However, users expect it to significantly boost the efficiency of the Ethereum network with its off-the-chain side operations.
