Plasma Cash Simple Spec PublishedHappened on March 14th, 2018A Plasma chain is a separate blockchain anchored to Ethereum Mainnet but executing transactions off-chain with its own mechanism for block validation. Plasma chains are sometimes referred to as "child" chains, essentially smaller copies of the Ethereum Mainnet. Plasma chains use fraud proofs (like optimistic rollups) to arbitrate disputes.
Plasma Cash is a Plasma construction based around the use of unique identifiers for each token on the Plasma chain. Similar to cash in your pocket, tokens on the network are given unique serial numbers.
