Chaumian ecash David Chaum invented this in 1982. DigiCash (1989) failed. In 2022–23, Bitcoin revived it: • Cashu (by "Calle") — single-operator mints • Fedimint (by "Elsirion") — federated mints (15–30 guardians) Both use Chaum's blind signatures. How it works: Deposit BTC → mint Get ecash tokens Spend instantly, privately, free Redeem back to BTC/Lightning Custodial. Use for daily, not savings. Running in El Salvador, Lugano, Madeira, Kenya. #Bitcoin #Crypto #NewJersey #Tech #BitcoinPizzaDay

#Quantum vs #Bitcoin — 2026 update Threat is real (Shor's algorithm breaks ECDSA). Timeline tightened in past 6 months: • Google (Mar 2026): fewer qubits needed than thought • Project Eleven (May 2026): Q-Day by 2030–2033 • 25–40% of BTC sits in exposed-pubkey addresses Defense is also real: • NIST PQC standards finalized Aug 2024 (ML-DSA, ML-KEM, SLH-DSA) • BIP-360 = Bitcoin's post-quantum proposal • BTQ Technologies demoed quantum-safe Bitcoin Oct 2025 • Algorand already did a PQ tx Today: don't buy "quantum-proof" altcoins selling fear. Watch BIP-360. #BitcoinPizzaDay #Tech #NewJersey

AI + Bitcoin AI agents can't use credit cards. Too much friction, no autonomy. L402 (Lightning Labs): HTTP 402 + Lightning invoice + macaroon token. Pay-per-request. No accounts. No API keys. Just payment as authentication. 2/ How it works: Agent → request Server → 402 + invoice + token Agent → pays via Lightning, gets preimage Agent → resends with proof Server → serves resource Cloudflare: 1B+ 402 responses/day in 2025. #Crypto #Bitcoin #BitcoinPizzaDay #Tech #NewJersey

Citrea & Chainway Labs Chainway = the company. Citrea = the rollup. First Bitcoin ZK-rollup, mainnet live since Jan 27, 2026. EVM-equivalent zkEVM (on RISC Zero). Any Ethereum contract deploys unchanged. 2/ Funded: • $2.7M seed (Galaxy, Feb 2024) • $14M Series A (Founders Fund, Oct 2024) Three pieces: • Clementine — BitVM bridge • cBTC — trust-min BTC • ctUSD — Treasury-backed stablecoin 30+ ₿apps live at launch. 3/ Skeptical view: single sequencer, federation-backed bridge. Bitcoin stores proofs, not logic. Trust moved, not removed. Both takes have merit. #Bitcoin #Crypto #DeFi #NewJersey #Tech

Bitcoin on ICP Normal "BTC on X chain" = custodian + wrapped token + bridge risk. ICP route: canisters sign real BTC txs using threshold ECDSA. Private key is split across the node network — never reconstructed. Live since November 2022. ckBTC = actual BTC, native, no bridge. 1:1 backed, 1–2 sec finality. Different trust model: you're trusting ICP consensus instead of a bridge custodian. Worth understanding before deposit.
