The Aptos Foundation has proposed an overhaul of APT tokenomics that would cut annual staking rewards from 5.19% to 2.6%, raise gas fees tenfold, and cap total supply at 2.1 billion APT. Under the plan, the Foundation would permanently lock and stake 210 million APT — nearly 18% of current supply — with operations funded by staking rewards rather than token sales.

The Foundation says the changes are intended to reduce emissions and increase token burns, potentially making APT deflationary. Future ecosystem grants would be tied to performance milestones, and annualized token unlocks are expected to fall 60% as the initial four-year unlock cycle ends in October 2026.

The measures remain a proposal rather than an executed change. A buyback program funded by cash reserves and future revenue is also under consideration.

An address labeled "U.S. Government: Bitfinex Hacker Seized Funds" transferred out 12,267.02 BTC, worth about $1.006 billion, on October 8 (13:33 UTC / 21:33 Beijing time). Of that, 6,000 BTC was split into two transfers to a new address beginning with 33pYK…cFk, while roughly 6,267 BTC was held in another new address.

The destinations have revived concerns about potential government selling, though transfers to Coinbase Prime do not by themselves prove the Bitcoin was liquidated. The Oct. 8 movement extended three consecutive days of government-linked Bitcoin transfers.

In the prior hours, US government-linked addresses had moved a cumulative $670 million in tokens: 6,215.7 BTC ($520 million), 119 million USDT and 40,285 BNB ($31.63 million), with the BTC and USDT routed into Coinbase Prime. Blockchain analyst EmberCN reported that 9,000 BTC, worth about $739 million, had reached Coinbase Prime, and Coinbase Prime serves as a custody and trading venue, so assets can be deposited without an immediate sale.

Securitize launched Securitize Stocks, a product offering tokenized U.S. equities backed one-to-one by real shares, opening with security entitlements to 12 widely held names including Apple, Microsoft, Nvidia, Google, Tesla, Meta, Amazon, Netflix, Circle, Strategy and Palantir. The tokens initially trade on Securitize's registered broker-dealer platform on Solana, settling in the USDC stablecoin.

Securitize says each token is a security entitlement under the Uniform Commercial Code rather than a price-tracking wrapper, preserving investor rights and economic benefits such as dividends and, where applicable, voting. That distinguishes the offering from many offshore tokenized-equity products that only track a stock's price.

The shares backing the tokens will not be lent out, and holders can convert their entitlements into actual registered shares where an issuer supports it, with the product available to eligible investors in the U.S., the European Union and other permitted jurisdictions. At launch liquidity runs through Securitize's Solana-based automated market maker with Jump Trading as market maker, trading is available during extended hours ahead of a planned move to 24/7, and partners include Ripple Prime and Aave; Securitize says the tokens are expected to trade on the NYSE's planned 24/7 venue and the OKX-ICE tokenized-securities venue, neither of which has launched.

Boris Blokhin, senior managing director at the Moscow Exchange (MOEX), told reporters that the exchange plans to launch cryptocurrency trading on December 1 under Russia's new regulations. He said testing will continue until the official launch, according to TASS.

MOEX is Russia's main stock exchange, so its stated plan to host crypto trading would place digital assets within the country's core regulated market infrastructure rather than only on offshore or unlicensed venues.

The service is still in a testing phase and has not gone live; Blokhin did not specify which instruments would be traded or the scope of the offering.

The Sui Foundation announced that Hashi, its native Bitcoin financial infrastructure, will begin a phased mainnet launch this month, backed by more than $500 million in capital commitments and a launch coalition of over 20 crypto industry institutions. Anchorage Digital is joining as a first-batch partner, providing institutional access through its Atlas settlement and triparty collateral infrastructure and its Porto self-custody wallet, and plans to supply stablecoin liquidity to Hashi.

Hashi is designed to let BTC remain on the Bitcoin network while being used as programmable collateral on Sui, a structure aimed at institutions that hold large Bitcoin balances. Anchorage Digital CEO and co-founder Nathan McCauley said public companies and institutions hold enormous amounts of Bitcoin but their ability to use that capital has been constrained by available technology and the limitations of DeFi.

Users deposit BTC, Hashi mints corresponding hBTC on Sui, and on exit the hBTC is burned and the native BTC is released back to the Bitcoin network. Security is built on MPC, Sui smart contracts and a Guardian Layer, with BTC collateral using a 2/2 multisig authorized jointly by Hashi validators and Guardians; the smart contracts have undergone Certora formal verification and CommonPrefix completed a cryptographic security review of the MPC protocol.

According to monitoring by Defimon Alerts, the 79th Vault (79AU) on BNB Chain lost approximately $12.5 million after a suspected private key leak in its operations hot wallet. The address moved 2.01 million 79AU out of its trading pair in seven transfers (10,000; 100,000; 100,000; 300,000; 500,000; 500,000; and 500,000 tokens), and the attacker sold them back through about 95 swaps, cashing out 16,249 BNB (about $12.5 million).

The pool's USDT reserves fell from $15.2 million to $3.9 million, meaning liquidity providers and users in the 79AU trading pair absorbed the losses. The incident is a suspected key-compromise drain on BNB Chain DeFi rather than a contract logic exploit per the cited monitors.

The operating key also sent 3.79 BNB to the same external address, and another 500,000 79AU was moved to other addresses. The 79AU contract source code is not verified on BscScan, so outside reviewers cannot compare published code with what runs on chain.

Payward, the parent company of the Kraken exchange, has closed its acquisition of crypto derivatives platform Bitnomial, giving it a full set of US derivatives licenses covering exchange, clearing and brokerage functions.

The deal places a fully CFTC-licensed derivatives stack — designated contract market, derivatives clearing organization and futures commission merchant — inside one of the largest US crypto exchange groups. Kraken has said the combination brings Bitnomial's CFTC-licensed infrastructure together with its client base and distribution across Kraken, NinjaTrader and its wider product family.

Reports put the transaction at $550 million in cash and stock. The licenses gained cover the three core US derivatives functions: exchange (DCM), clearing (DCO) and brokerage (FCM).

A report published by shattered.io alleges that crypto exchange Bitget lost $388 million in an exploit said to involve a zero-day vulnerability. The claim has not been confirmed by Bitget, on-chain analysts or other outlets.

If the alleged figure is accurate, the incident would rank among the largest security failures at a crypto exchange on record. As reported so far, no exchange statement, on-chain evidence or independent coverage has been cited to support the number.

The claim originates from a single headline on shattered.io, a non-mainstream outlet, and no on-chain data or corroborating reporting accompanies it. Bitget has not publicly acknowledged any such breach.

OpenAI has withdrawn three mathematical results from its openai/math repository, according to the repository's history file, which was circulated in a post by @danintheory. The repository hosts mathematical manuscripts and supporting proof artifacts produced by an internal OpenAI model.

The withdrawal focuses attention on how much trust should be placed in AI-generated mathematical proofs, especially results presented in natural language rather than backed by machine-checkable Lean certificates.

The openai/math repository holds 722 manuscripts across 372 result families and is released under Apache-2.0. Some of the proofs include Lean formalization that computers can check, while others do not.

Three fired OpenAI safety researchers publicly rejected allegations that they mishandled sensitive information, publishing an open letter that disputes the misconduct claims and warns their dismissals are chilling AI safety work inside the company. In the letter they wrote that "given the significant safety concerns surrounding the development of AI, employees must not be left working in an environment where fear and unclear rules stymie AI safety work and weaken third-party accountability."

The letter frames the dismissals as a governance issue rather than a purely personnel matter, arguing that the way the cases were handled affects how safety work and third-party accountability function at a leading AI lab.

The researchers dispute the characterization that they improperly shared sensitive information; earlier reporting linked the dismissals to allegations of sharing information with external safety groups.

Anthropic announced OSS Scanner, an opt-in service that uses its models to run thorough, periodic security scans of open-source software repositories and alert projects to potential vulnerabilities at no cost.

According to the source, open-source projects that opt in could be alerted about possible security issues sooner; the trade-off is described as stemming from how OSS Scanner works.

The service is described as free to participating open-source projects and uses Anthropic's strongest models for periodic scanning; participation is opt-in rather than automatic, and the company maintains a public repository for the service.
