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.

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.

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.

TABConf 7 Live 2025: Bitcoin Fundamentals and Self Custody Workshop with William K. Santiago
William K. Santiago leads a practical workshop on Bitcoin fundamentals and self custody. The session covers how Bitcoin works, wallets, UTXOs, fees, and transactions, then moves into hands on self custody setup and security practices. Attendees learn how to work with hardware wallets including SeedSigner, Jade, and Coldcard, how to generate and protect seed phrases, and how to avoid common mistakes. The workshop also covers recovery and inheritance planning so participants can move from exchange custody to true Bitcoin ownership with more confidence.

TABConf 7 Live 2025: Fedimint Deep Dive Workshop with Justin
A technical deep dive into Fedimint, a federated eCash mint for Bitcoin communities. This workshop starts with a high level overview of federation design, including trust assumptions, guardian roles, Lightning integration, and user roles. It then goes deeper into networking internals and how the peer to peer plus client server stack works in practice.
The session also covers how Iroh can simplify federation setup through direct peer connections without requiring public IPs or domain names, making deployments on platforms like Start9 or Umbrel more practical. If you want to deploy community mints with cleaner operations and better UX, this workshop maps the path.

TABConf 7 2025: Adding Silent Payments Support to BDK | TABConf 7
A workshop preview of the work underway to support silent payments in BDK, with a practical walkthrough of the experimental bdk-sp repository and its modular design combining BDK with BIP352. You’ll see how a silent payment wallet can be implemented in practice, including transaction creation, incoming payment discovery, spending flows, labeling, and a possible PSBT based approach.
If you’re new to this area, you’ll walk away with a clear understanding of how silent payments fit into BDK architecture, what the end to end wallet flow looks like, and which Bitcoin primitives matter most to follow along.

TABConf 6 2024: BitVM, a BTC Bridge, and zkCoins
An introduction to the BitVM paradigm and a concrete implementation path, including a BTC bridge being built on top of it. The talk also presents zkCoins, a second layer protocol aimed at boosting base layer throughput by more than 10x while enabling strong privacy. If you’re new to this area, you’ll walk away with the basics of BitVM, the basics of zkCoins, and how these pieces fit together in practice.

TABConf 7 2025: Bitcoin Clients and Mobile, Challenges and Possibilities with Davidson Souza and João Victor
Bitcoin is a peer to peer network, and real sovereignty means running your own client instead of trusting a third party. With most of the world on smartphones, bringing Bitcoin clients to mobile is a big unlock for decentralization, privacy, and user empowerment.
In this talk, Davidson Souza and João Victor share what they built at SatsHack 2024: a BDK based wallet using Floresta, a Utreexo powered Bitcoin light client for Android. They cover verification, local transaction discovery, running continuously like a node, broadcasting directly to the P2P network, plus what worked, what hurt, and the technical challenges that make mobile clients hard and worth it.
Featuring Davidson Souza and João Victor.

TABConf 7 2025: Quantum Rotating Debate Panel with Hunter Beast and Sho Sugiura
A live rotating debate at TABConf 7 Live 2025 on the intersection of quantum computing and Bitcoin.
The session starts with a short premise presentation, then shifts into an open, rotating Q&A and debate where audience members can step on stage to challenge assumptions, ask questions, and sharpen the discussion in real time.
Featuring Hunter Beast and Sho Sugiura.

TABConf 7 2025: Post-Quantum Signature Aggregation with Tadge Dryja
Cross-Input Signature Aggregation (CISA) has been on Bitcoin’s radar for years, but with small elliptic curve signatures the tradeoffs rarely justified a soft fork. Post-quantum signatures change the calculus.
Tadge Dryja makes the case for a CISA variant that can work with any signature scheme, including post-quantum, to reduce the footprint of larger PQ signatures without increasing block size.
A practical look at how signature aggregation could make a post-quantum path more efficient for Bitcoin’s future.
