The Specter DIY, SeedSigner, and Krux teams were all brought together for a DIY hardware summit in São Paulo Brazil last month, led by Stepan Snigirev. CryptoGuide was there to represent his SeedSigner + Satochip smartcard fork as well as Lawrence Nahum to share his deep knowledge of the Jade development.

Building a vault using blinded co-signers

MuSig2 + ZKP Vault PoC “Unlike traditional setups involving co-signers, this scheme uses a blinded version of Musig2 to ensure the signers learn as little as possible about the on-chain movements of the funds they are involved in co-signing.”Delving Github

The Cat - Non-monetary UTXO Cleanup

A bip proposal to make “designated Non Monetary UTXOs (NMUs) permanently unspendable… Once rendered unspendable, we will be removing these UTXOs made unspendable by consensus under this proposal, from the UTXO set…”

Hash-based Signature Schemes for Bitcoin

3-4kb quantum resistant signatures possible via performance tuning NIST libraries. The report also discusses broader considerations:

  1. Trade-offs between stateless and stateful schemes
  2. Compatibility with HD wallets
  3. Limitations of current approaches for multi- and threshold signatures
  4. Security targets

Hands-On DIY Signing Device Demos

We’ll pass around Specter DIYs, SeedSigners, Kruxes, a Jade DIY, and even a SeedSigner+Satochip build with some demo seeds and testnet funds. Create watch-only wallets, review psbts, sign txs.

Open Q&A on the differences between them, use cases, risks, etc.
