Obscura: Privacy-Preserving Protocol for the Algorand Blockchain Using LSAG Ring Signatures
Obscura is a privacy protocol for Algorand that hides transaction details using Linkable Spontaneous Anonymous Group (LSAG) signatures. It achieves anonymity by combining these signatures with a novel state model and dynamic budget expansion to bypass Algorand's execution limits, allowing users to spend funds without revealing which specific commitment they are using.
