<p>Mentor Sessions Ep. 056: Bitcoin Privacy Is At Risk (But These Fixes Are Coming) | NVK &amp; Francis Pouliot</p><p><br></p><p>Address reuse is silently destroying Bitcoin privacy—and most Bitcoiners have no idea how exposed they are. Coinkite founder NVK and Bull Bitcoin founder Francis Pouliot break down the most critical privacy vulnerabilities in Bitcoin today, why kidnappings tied to crypto wealth are surging across Europe (one every four days in France), and the technical solutions finally closing the gap. From silent payments and async pay join to BIP322 proof of reserves and UTXO management, this is the most comprehensive Bitcoin privacy conversation of 2025. Learn why giving your xpub to an exchange is catastrophic, how 5% pay join adoption could break chain analysis entirely, and why Nostr disposable identities may be the missing piece for private payments. If you hold Bitcoin, this episode could protect your life—not just your stack.</p><p><br></p><p>About NVK: Founder of Coinkite, creators of the COLDCARD.</p><p>🐦 https://x.com/nvk | 🌐 https://coinkite.com</p><p><br></p><p>About Francis Pouliot: CEO of Bull Bitcoin.</p><p>🐦 https://x.com/francispouliot_ | 🌐 https://bullbitcoin.com</p><p><br></p><p>Chapters:</p><p>00:00:00 Teaser &amp; Intro – Bitcoin Privacy Risks Are Real</p><p>00:01:05 Where Bitcoin Self-Custody Stands Today</p><p>00:03:32 Three Unsolved Bitcoin Problems: Privacy, Speed &amp; Inheritance</p><p>00:05:46 The UX Problem: Aggregating Bitcoin Tools</p><p>00:08:16 Dangers of Single-Vendor Bitcoin Solutions</p><p>00:11:27 Silent Payments Explained: What They Are &amp; Why They Matter</p><p>00:13:06 Async Pay Join &amp; BIP77: Underused Privacy Tool</p><p>00:15:35 Why Receiving Silent Payments Is Hard</p><p>00:17:10 Nostr as a Payment Identity Layer</p><p>00:19:41 Disposable Identity: The Missing Privacy Piece</p><p>00:23:00 Silent Payments Into Wasabi: The Dream Flow</p><p>00:28:13 Why xpub Sharing Is a Privacy Disaster</p><p>00:30:44 On-Chain Privacy vs Layer 2 Privacy</p><p>00:33:38 How Pay Join Breaks Chain Analysis</p><p>00:37:11 Network-Level Privacy Tools: Kyoto &amp; Floresce</p><p>00:39:43 Why Bitcoin Kidnappings Are Surging in Europe</p><p>00:41:32 Identity Leaks &amp; KYC Data Exposure</p><p>00:44:04 ColdCard Firmware: BIP322 Proof of Reserves</p><p>00:48:20 WIF Private Key Signing on ColdCard</p><p>00:51:34 UTXO Management: The Underrated Problem</p><p>00:54:14 Push Transactions &amp; Broadcast Privacy</p><p>00:59:43 Migrating Wallets Privately: The Right Way</p><p>01:05:06 Lightning at Merchant Scale: Still Not There</p><p>01:09:39 Cashu Mints, Federation Models &amp; Trust Trade-offs</p><p>01:14:26 MintChip: Canada&#39;s Forgotten Digital Cash</p><p>01:19:57 Liquid Network, Stablecoins &amp; Confidential Transactions</p><p>01:32:44 Depix: Brazil&#39;s Liquid Stablecoin Explained</p><p>01:37:00 Bitcoin Development Happening at the App Layer</p><p>01:39:17 What&#39;s Coming from Coinkite &amp; Bull Bitcoin</p><p><br></p><p>⚡ Abundant Mines – Fully managed Bitcoin mining: https://qrco.de/bgYKPB</p><p>🔒 COLDCARD – 5% off the best hardware wallet: https://qrco.de/bfiDBV</p><p>🛡️ Dirty Man Safe – 10% off with code BTCSESSIONS: https://dirtymansafe.com</p><p>🏠 Horizon – Unlock home equity for Bitcoin: https://joinhorizon.com/?ref=BTCSESSIONS</p><p>💡 Bitcoin Mentor – Book a private session: btcmentor.io</p><p><br></p><p>Previous Episode with Matt Hill: https://youtu.be/Dv1-JfjxuAY</p><p><br></p><p>Follow Us on X: @BTCsessions | @theBTCmentor | @GaryLeeNYC</p><p><br></p><p>#Bitcoin #BitcoinPrivacy #SilentPayments #PayJoin #ColdCard #NVK #FrancisPouliot #BullBitcoin #Coinkite #UTXOManagement #BitcoinSecurity #ChainAnalysis #BIP322 #ProofOfReserves #LightningNetwork #Nostr #BTCSessions #BitcoinPodcast #SelfCustody #HardwareWallet</p>
