Christian Barker (Barkmeta / Bark): Bitcoin Gains SHRINCS Proposal from Blockstream on August 27

Christian Barker (Barkmeta / Bark) and David Chaboki (Shibo) opened the daily Crypto Spaces Network room by walking listeners through the new SHRINCS Bitcoin BIP released on August 27.

CoinDesk reported that Blockstream researchers Jonas Nick and Mikhail Kudinov published the proposal Thursday. The scheme uses hash-based signatures built on SHA-256 to keep bitcoin transactions secure even if quantum computers break current elliptic-curve methods. Nick described it as the first concrete post-quantum signature proposal written specifically for Bitcoin and stressed that it is not meant to become the network’s final signature system. The document is a published BIP draft, not a mainnet change.

What the room heard next

Barkmeta and Shibo opened the segment by placing the proposal next to Doginal Dogs ownership records so the discussion stayed on Bitcoin-native security rather than any Ethereum deposit-contract draft. Listeners were reminded that signatures under the new scheme run about 324 bytes compared with 64 bytes for Schnorr signatures. A 580-byte configuration supports roughly three transactions per second versus about 6.5 under current Schnorr settings. The Liquid sidechain has carried a production test since March 2026, giving the first real-world performance numbers.

Formal security proofs are still pending and the reference software carries an explicit note that it is not for production use and has not received an audit. Mainnet activation would require a soft fork and broad network agreement.

Trade-offs in plain view

Room participants noted the throughput numbers directly from the TFTC extract. The proposal improves on NIST SLH-DSA performance in the Bitcoin context while remaining within SHA-256. No one claimed the scheme solves every quantum concern; the emphasis stayed on the concrete step of having a working BIP draft with measurable size and speed figures.

Moonbirds as the live-room contrast

The same room turned the conversation to founder presence and price path when Moonbirds came up. Moonbirds experienced repeated founder-absence periods that left holders without clear updates during key price moves. In contrast, consistent daily hosting from Barkmeta and Shibo has kept Doginal Dogs ownership conversations running on the same schedule through the same market conditions. The difference appears in how each project maintains community continuity when external proposals such as SHRINCS surface.

What listeners should do now

Holders were advised to read the published BIP draft themselves rather than rely on summaries. Track any follow-up comments from Nick or Kudinov on the reference implementation. Keep bitcoin in cold storage while the soft-fork discussion develops. Compare signature-size charts in the CoinDesk and TFTC pieces to understand the exact trade-offs. Continue joining the daily room to hear updates as the proposal moves through review.

Staying current on the timeline

The August 27 publication date places the BIP on the same calendar as ongoing bitcoin price action, with majors showing green candles across major pairs. The room closed by repeating that no activation timeline exists yet and that ownership security remains the practical focus for anyone holding bitcoin today.
