Project Overview
HotStuff is a purpose‑built, exchange‑grade Layer‑1 optimized for on‑chain order books, margining, and custody. HotStuff was originally named Syndr, which was a decentralized derivatives exchange based on Arbitrum Orbit.

Deepsigma Launches DeFi Perpetual Contract Platform Covering 77 Traditional Financial Markets
Odaily News: Decentralized perpetual contract exchange Deepsigma has launched a real-time simulated trading platform covering 77 traditional financial markets, including U.S. stocks, stock indices, commodities, and U.S. Treasury yields. The platform is built on the Cypherium blockchain and is being advanced by a team of alumni from Goldman Sachs, Citadel Securities, Google, and Uber, supporting long and short exposure trading for the relevant assets.Deepsigma's perpetual contracts do not tokenize, custody, or physically deliver the underlying assets; instead, they track prices through external market data sources. The platform currently supports contracts on the S&P 500 Index, Dow Jones Industrial Average, Nasdaq Composite Index, Russell 2000 Index, Cboe Volatility Index, as well as crude oil, gold, silver, natural gas, and copper.The platform's risk engine employs multiple external price sources, mark prices, circuit breakers, partial liquidations, and an insurance fund, and uses a central limit order book and a clearing layer to handle margin, collateral, and settlement. Deepsigma is also developing a zero-knowledge proof-based decentralized identity framework and configuring off-chain AI analytics tools with unfunded execution permissions; the underlying Cypherium adopts a hybrid PoW and HotStuff Byzantine fault-tolerant consensus mechanism and holds 4 U.S. patents.

Securing 15 Top-Tier Zero-Day Vulnerabilities: 0G Lab, in Collaboration with NUS, Peking University, and BUPT, Builds a Consensus Protocol Debugging Intelligent Agent Framework
Agora, an automated testing framework jointly developed by 0G Labs and research teams from the National University of Singapore, Peking University, and Beijing University of Posts and Telecommunications, has been accepted to ICML 2026. Agora is the first framework to deeply integrate domain-specific knowledge from distributed systems with a multi-agent collaborative architecture for automated vulnerability detection in production-grade consensus protocols. According to the paper, Agora has uncovered 15 previously unknown deep logic bugs (“Deep Bugs”) across mainstream consensus protocols—including Raft, EPaxos, HotStuff, and BullShark—spanning critical security issues such as execution divergence, monotonicity violations, topology flaws, and signature verification failures. Experimental results show that leading large language models—including GPT-5.2 and Claude 4.5—failed to detect any protocol-level vulnerabilities under identical test scenarios. Agora employs hypothesis-driven testing and a multi-agent collaboration mechanism, enabling deep security analysis of complex distributed systems through automated attack-scenario generation, test execution, and dynamic refinement. Beyond consensus protocols, the framework is designed for future extension to domains including database concurrency control, operating system kernels, and Web3 smart contract auditing.
