Plasma was an idea floated a few years ago for "sidechains that have a non-custodial property: if there is any error in the Plasma chain, then the error can be detected, and users can safely exit the Plasma chain and prevent the attacker from doing any lasting damage. " Source: vitalik.ca
The big issues that plasma wanted to solve were:
- Availability: If you participate in a sidechain, you should be able to mint/burn/view from the mainchain at any time, regardless of the status of the sidechain network.
- Fraud Detection: If there’s a cryptographic error that’s accepted by the sidechain, the mainchain can detect it and redirect funds appropriately.
Granted, nobody ever got this working before rollups stole all the attention. But I’m wondering, what are you guys’ thoughts on these issues?
