On October 2, at 11:30 AM Eastern Time, the Arbitrum Security Committee executed an emergency upgrade on Arbitrum One and Nova, suspending the activation of all new Stylus contracts on both chains, while adding a protective mechanism against BoLD single-step proofs in the dispute system of Arbitrum One. The Arbitrum Foundation stated that this action is part of ongoing proactive security measures aimed at protecting the security and integrity of the network.Stylus allows developers to write smart contracts using languages such as Rust and C++, while maintaining compatibility with the Ethereum Virtual Machine, with its programs compiled into WebAssembly format. This suspension primarily targets manually written WASM programs that do not use the standard Stylus compiler toolchain and have not yet been patched by the current version of ArbOS. The Security Committee increased the gas required for activation to the theoretical maximum by calling ArbOwner.setWasmActivationGas(2^64 - 1), making new activations economically unfeasible. Activated Stylus contracts are unaffected and can continue to execute and renew, and the deployment and execution of Solidity contracts are also unrestricted.The newly added BoLD protection allows anyone to pause the settlement from Arbitrum One to Ethereum when two conflicting and accepted answers appear in the same dispute step, which may delay unconfirmed withdrawals to allow the Security Committee to deploy fixes. Officials pointed out that the currently discovered Stylus-related vulnerabilities mainly affect the activity of the chain, such as denial-of-service attacks, and do not jeopardize user funds.

AI startup Tavus released a new model called Griffin on October 1, referring to it as the first "human interaction model" that can understand and generate face-to-face conversations, paying attention not only to wording but also to expressions and pauses. Tavus stated that in tests, after a one-minute video call with Griffin-Lite, 26 out of 54 participants (48%) believed the other party was a real person; its previous generation system only convinced 1 out of 41 participants.Participants were told they would have a one-minute video call with another person to discuss things they were looking forward to this year, and only at the end of the call were they asked if they suspected the other party was not a real person. Tavus noted that those who became suspicious typically noticed within 20 seconds. This result comes from Tavus's own research page, where participants were recruited through a channel they call an independent research platform. Community comments on X pointed out that these results have not been independently verified and do not meet standard protocols.In the NVIDIA VideoFDB benchmark, Tavus claimed Griffin-Lite ranked first, with a generation dimension score of 3.83, the next best system scoring 2.8, and human reference scoring 3.92; the perception dimension score was 3.73, with the strongest baseline at 3.44 and human reference at 4.2. Tavus stated that NVIDIA independently conducted this evaluation. Griffin supports full duplex, allowing it to listen, see, and speak simultaneously, with an average audio-video delay of 0.43 seconds on the NVIDIA H100 chip. Tavus completed a $40 million Series B funding round led by CRV in November 2025.

DogeOS, the application layer of Dogecoin, launched its public testnet on Wednesday, introducing EVM-compatible smart contracts to the Dogecoin network as a zero-knowledge rollup, with DOGE as the native token for transaction fees. The project aims to support applications such as trading, lending, stablecoins, prediction markets, and gaming, while settling state back to the Dogecoin network.DogeOS currently uses a trusted execution environment, validators, and a permissioned sequencer to ensure network security. Future proposed upgrades to Dogecoin Core will allow Dogecoin miners to directly verify their execution proofs. DogeOS CEO Jordan Jefferson stated that Dogecoin does not currently verify ZK proofs on its own, and bridging state transitions requires valid proofs as well as signatures from a majority of validators and TEE signers. He mentioned that the team is currently focused on the public testnet, allowing developers time to build and test applications, with the mainnet timeline to be announced upon reaching the next development milestone.DogeOS comes from the MyDoge wallet team, which announced a $6.9 million funding round led by Polychain Capital in May 2025. Two months later, the DogeOS team submitted a proposal for a Dogecoin Core upgrade to add native ZK proof verification for Dogecoin, but this upgrade has not yet been implemented. Timothy Stebbing, a director of the Dogecoin Foundation, expressed hope that DogeOS will serve as a springboard for a new wave of practical engineering.

The U.S. Securities and Exchange Commission (SEC) has proposed a reform plan aimed at expanding the channels for individual investors to participate in the private market.

The SEC also proposed to broaden the definition of "accredited investors."
