Nick, co-founder of Gamma, joins us to talk about the broken NFT market discovery process and how their new platform Signals fixes the ridiculous whitelist system.

The Bitcoin Attack You Haven't Heard About
PortlandHODL explains Bitcoin's most dangerous vulnerability: poison blocks. These malicious blocks can freeze nodes for 11+ hours on Raspberry Pi devices and 25 minutes on enterprise hardware, creating profitable attack opportunities for miners while exposing how relay policy acts as an accidental guardian of the network.
Follow our guests: @PortlandHODL
Notes:
• Poison Blocks (denial of service)
• Raspberry Pi validation: 11 hours for poison blocks
• Enterprise hardware: 25 minutes validation time
• Attack gives 20% effective hash rate boost
• Fix exists in Great Consensus Cleanup
• Bitcoin fees currently under $1

• GPU mining was 10x more powerful than CPU mining
• Bitcoin hash rate increased 130,000% by end of 2010

What the Samourai Case Means for the Future of BTC Privacy
Seth for Privacy, VP at Cake Wallet, joins us to discuss the ongoing Samurai Wallet legal case and its implications for Bitcoin privacy. Seth explains how the DOJ's prosecution of Samurai developers threatens the entire crypto privacy landscape, despite FinCEN's admission that self-custodial wallets shouldn't be regulated as money services. He breaks down Bitcoin's current privacy limitations, highlighting promising technologies like Silent Payments and Payjoin V2, while candidly addressing why Monero offers superior privacy by design. Are we re-living through the same cryptography battle we fought in the 90s?
Follow our guests: @Sethforprivacy
Notes:
- Samurai indicted April 24, 2024, despite self-custody
