• MIT Bitcoin Expo 2015 transcripts were rapidly produced and published under CC-BY-SA 3.0 on diyhpl.us/wiki/transcripts/mit-bitcoin-expo-2015/, capturing technical talks on threshold signatures, sidechains, scalability, and a deep dive into Zerocash and libsnark for practical zk-SNARK-based anonymous Bitcoin transactions.

• Zerocash’s use of libsnark was highlighted as the first real-world deployment of succinct non-interactive zero-knowledge proofs enabling fully private payments, with links to the underlying SNARK papers and cautionary notes on prior threshold-signature implementation pitfalls.

• Distributed Autonomous Organizations (DAOs) were debated as “corporations without paperwork,” accompanied by skepticism about blockchain hype and a reference to Primavera De Filippi’s Swarm working paper on the legal status of decentralized networks.

• Assembly Coins were criticized for forcing users into proprietary alt-coins before token issuance, contrasting with open protocols like Counterparty, Mastercoin, and NXT, and were noted to omit any DAO-related functionality.

• High-intensity interval training (HIIT) was presented as a time-efficient alternative to endurance running, supported by a large literature base showing equivalent or superior metabolic benefits while avoiding documented endurance pathologies such as intestinal permeability, atrial fibrillation, coronary calcification, and elevated cardiac-event risk (citing J Appl Physiol, BJSM, Eur Heart J, and AHA journals).

• Electrical muscle stimulation (EMS), once marketed as “Russian muscle stimulators” and later as consumer ab-toning belts, remains FDA-regulated after FTC crackdowns and is now a niche tool for strength and aesthetic enhancement.

• Seasteading.org launched a new discussion forum, prompting a Snow Crash “raft” analogy and illustrating the channel’s eclectic sourcing, while Bay Area participants coordinated in-person meetups in San Francisco/San Jose around Bitcoin and biohacking interests.
