Hash-Based Signatures
This presentation is a "from first principles" introduction to Hash-Based Signatures which are signature schemes that can be constructed solely from Hash Functions.
Hash-Based Signature Schemes are interesting in that they're considered secure against the threat of Quantum Computers.
Given this security assumption they're potential candidates to replace the BLS Signature Scheme that's currently used for Ethereum's Proof-of-Stake consensus.
The presentation was held as part of the "Ream Calls" series in which educational content is shared with the Ethereum Community to discuss how the next version of Ethereum's consensus layer might look like.
Hash-Based Multi-Signatures for Post-Quantum Ethereum
This presentation is a deep dive into the ways in which Hash-Based Signature Schemes could be used in a future version of Ethereum's Proof-of-Stake consensus.
The current consensus implementation uses the BLS Signature Scheme that's not considered quantum secure as it relies on Elliptic Curve Cryptography.
The presentation was held in front of the Ethereum Community as part of the "Ream Calls" series in which educational content is shared to foster discussions around the next version of Ethereum's consensus layer.
