• A new transcript series covering the 2019 Magical Crypto Conference was added to the diyhpluswiki, including panels on “cryptographic hocus-pocus” with Peter Todd, the future of privacy coins, fork dynamics in blockchains, andytoshi’s talk on “crypto in cryptocurrency,” and a debate on why block sizes should not be too large.

• Fresh transcripts of Andreas Antonopoulos were also posted: one on Schnorr signatures (a proposed Bitcoin signature aggregation scheme) and another on Initial Block Download (IBD) optimization techniques.

• A YouTube link was shared to a lab demonstration of focusing light inside opaque scattering media via optical phase conjugation, with commentary praising the paper as a thorough, realistic-conditions summary of the group’s recent work.

• All new material is publicly archived at http://diyhplus.us/diyhpluswiki/transcripts/ and linked through the diyhpluswiki git repository, providing an open, searchable record of cutting-edge cryptocurrency and cryptographic research discussions.
