DHCoin은 등록된 도메인 기반의 K-위원회가 두 단계로 합의하는 방식으로 즉시 최종성을 보장하는 포크 없는 암호화폐 프로토콜입니다. SHA-256을 반복 적용하는 순차 지연 해시를 이용해 무작위성을 생성하며, 이를 통해 위원회 멤버가 블록 생성 기여를 결정할 때 무작위성을 미리 알 수 없도록 하여 선택적 중단 공격을 방지합니다. 블록은 모든 K 위원회의 Ed25519 서명을 필요로 하며, 위원회 멤버 중 하나라도 침묵하면 블록 생성이 중단되지만 프로토콜이 이를 감지하고 우회합니다. 이 구조는 포크가 발생하지 않고, 검열 저항성과 무작위성 편향 방지를 동시에 달성합니다.
eddieozComputador quântico: o que realmente ameaça o Bitcoin?
O Bitcoin vai morrer por causa do computador quântico? 🤔🚀
• Contexto rápido:
- A Carol comentou sobre o medo do computador quântico e as soluções sugeridas por Satoshi.
• O que isso significa na prática:
- SHA256 é muito mais forte que ECDSA. 🔐
- Se um hash ficar fraco, troca-se o hash. 🔁
- Se um algoritmo de assinatura digital ficar fraco,...

N-gated Hacker News🎉 "We broke 92% of SHA-256!" cries the self-congratulatory parade, flaunting their not-so-peer-reviewed #research. 🤔 But fear not, the paper (sponsored by 'dataplay.ai' – totally unbiased, right?) has all the cryptographic wizards shifting to... well, something. Maybe. 🧙♂️🔮

SmartGitGit 3.0 is coming. Are your tools ready? 🛡️
In our latest SmartGit Preview 26.1.011, we’ve officially introduced #Git 3.0 compatibility, targeting the 2 biggest architectural changes:
✅ SHA-256 Support: Moving beyond SHA-1 to ensure long-term cryptographic security and collision resistance.
✅ Reftable Support: A new storage format for refs that solves the "thousands of branches" performance bottleneck. No more scanning thousands of tiny files in .git/refs.

Git 3.0: Major Changes Ahead | Ron Northcutt posted on the topic | LinkedIn
Git 3.0 is on the horizon, and it is bringing some of the biggest changes we have seen in a decade. I recently followed a deep dive into the future of Git based on Patrick Steinhardt’s session at FOSDEM 2026. The focus is shifting from just maintaining the tool to evolving it for massive scale and better developer experience. Git 3.0 is about making the tool more robust for the next ten years of software development. Author: ennael Source: OSSFlow Link in the comments
Hugo van KemenadeThanks to @Monorepo for doing most of this, which needed changes to both the release process and the website: releases since 13th January now show SHA-256 checksums instead of MD5!
