TABConf Sessions

TABConf 4: Bitcoin Legal Panel with Justine Harper, Hussein Badakhchani, Zack Shapiro, and Desiree Dickerson

Description: A TABConf 2022 panel on the legal challenges and opportunities in Bitcoin. Justine Harper, Hussein Badakhchani, Zack Shapiro, and Desiree Dickerson cover regulation, compliance, and where the legal landscape is heading as Bitcoin adoption grows. Recorded live at TABConf in 2022.

TABConf 6: Build a Web Wallet with BDK 1.0

A hands on TABConf 6 workshop on building a simple descriptor based web wallet with BDK 1.0. The session introduces the new stable bdk_wallet API and why it matters: the Wallet struct decouples persistence and blockchain clients, making it easier to build apps using Rust async runtimes. You’ll build a web wallet using Axum, an Esplora client, and a SQLite database, covering the key steps: generating a new onchain wallet from a random mnemonic, using a pay to taproot (P2TR) descriptor, storing wallet state in SQLite, syncing transaction history over Esplora, and displaying balance plus transaction history. Recorded live at TABConf 6 in 2024.

TABConf 6: Soft Fork Covenant Dependent Layer 2 Review with Peter Todd

Peter Todd summarizes findings from his review of soft fork and covenant dependent Layer 2 designs, focused on proposals that scale Bitcoin by letting multiple users share UTXOs. The talk lays out what an L2 is in this context, what covenants are, and why shared UTXO L2 schemes typically require covenants to be viable. Peter then surveys the major proposals, with special attention to Ark, the covenant types each approach relies on, what scaling is realistically achievable, and what new risks and tradeoffs these designs introduce. Recorded live at TABConf 6 in 2024.

TABConf 6: Covenants and STARK proof verification with OP CAT

A TABConf 6 technical update on the progress of covenants and verifying STARK proofs on Bitcoin using the OP_CAT opcode. The talk walks through real applications, the current open source implementation, and a signet toy experiment that verifies a Fibonacci sequence using a chain of covenant linked transactions within standard relay policy limits. Expect a developer focused view of where the work stands today, what’s already running, and what OP_CAT enables for this design space. Recorded live at TABConf 6 in 2024.

TABConf 6: FROST, The Production Impact and Why It Matters

Bitcoin key management keeps getting more demanding, especially as more offchain tools still rely on hot keys instead of safer cold key setups. This TABConf 6 panel explores how breakthroughs like Flexible Round Optimized Schnorr Threshold Signatures, or FROST, alongside Taproot, are changing the way builders think about private key security. The discussion covers the basics of FROST, how it compares with onchain and offchain multisig tools, different key aggregation approaches, and where tools like Frostsnap and other collaborative custody models fit in. A strong session for anyone thinking seriously about the future of Bitcoin security, privacy, and production ready custody. Recorded live at TABConf 6 in 2024.
