According to CoinDesk, Ethereum developers released version 7.2.1 of the Prysm client on Monday evening, embedding a 200 million Gas limit to complete deployment ahead of the Sepolia testnet testing for the Glamsterdam upgrade on Tuesday.Glamsterdam is the next major upgrade for Ethereum, which will first be activated on the Sepolia testnet, where developers rehearse changes using tokens with no actual value. Part of Tuesday's testing involves raising the Gas limit on Sepolia from approximately 60 million to 200 million.Gas is the unit that measures how much computational workload a single block can accommodate on Ethereum. A higher limit means the network can handle more transactions and more complex activities simultaneously, but it also places higher demands on the computers running Ethereum. Prysm is the client software used by Ethereum validators, and its previous version had completed before this setting was added to the Sepolia configuration. Therefore, validators running the old version will still produce blocks with a 60 million Gas limit unless they manually modify the parameters, which undermines the effectiveness of this capacity test.Validators running the latest version will automatically start proposing blocks with a 200 million Gas limit when Glamsterdam activates on Sepolia at 13:53:36 UTC on October 6. Ethereum has been gradually increasing block capacity to test how far it can go before running validators becomes too demanding or expensive. The 200 million setting is only applicable to Sepolia, and Glamsterdam has not yet been activated on the Ethereum mainnet.

Polymarket has launched the next-generation prediction market smart contract system, Polymarket Protocol V2, which reconstructs the underlying architecture of the existing protocol. The current protocol is based on the Gnosis Conditional Tokens Framework from 2019, requiring additional adapters, trading contracts, and authorization processes for each new market type; V2 unifies this by using a single ERC1155 position token contract, pUSD collateral assets, trading platform contracts, and routers.V2 adopts a modular architecture, initially supporting binary, atomic negative risk, incremental negative risk, and composite markets, and connects to UMA, Chainlink, and other future oracles through a new OracleAggregator. The protocol natively supports cross-chain positions, collateral assets, and settlement results, reserving a foundation for future multi-chain deployments; all contracts can be upgraded under a secure governance process.V2 has been audited by Cantina, Certora, Quantstamp, SigmaPrime, Zellic, and Pashov, with formal verification completed by Certora, offering a maximum bounty of $5 million for critical vulnerabilities. Polymarket will operate a limited number of grayscale markets in the production environment from October 5 to 30, with plans to switch new markets to V2 starting November 2, along with the launch of Data API V2 built on Rust and an internal on-chain indexer.

The prediction market platform Polymarket has announced the launch of Polymarket Protocol V2, calling it the next-generation prediction market smart contract system. The existing contracts are based on the conditional token framework from Gnosis in 2019, with various markets subsequently integrated through additional adapters. V2 rebuilds position tokens from scratch, using a single ERC1155 position contract, a single collateral pUSD, a single exchange, and a single routing, with position IDs directly encoding market type, market, and outcome.V2 supports binary, atomic negative risk, incremental negative risk, and composite markets with a modular architecture, and expands position operations to enhance capital efficiency. Settlement is accessed through OracleAggregator, integrating pluggable oracles, including UMA, Chainlink, and future sources. The protocol features built-in cross-chain bridging designs for positions, collateral, and settlement, and can be upgraded through governance processes. Future research directions include scalar settlement and directional collateral return.The code has been audited by Cantina, Certora, Quantstamp, SigmaPrime, Zellic, and Pashov, and has undergone formal verification by Certora, with a maximum critical vulnerability bounty of $5 million. The canary market will operate in the production environment from today until October 30, with new markets tentatively scheduled to switch on November 2. At the same time, Data API V2 will be launched, based on a self-developed on-chain indexer, supporting V2, unified response formats, and cursor pagination.

According to Decrypt, Carli Michelle Heller, a woman from Bonita Springs, Florida, was arrested for using Claude as a diary. Investigators stated that she wrote about "shooting" the Lee County Sheriff's Office on September 26, and the next day claimed she had acquired a new gun. Anthropic's safety system flagged these conversations as serious, and the platform handed them over to a human review team, which reported to law enforcement. Officers then identified Heller, went to her residence, and detained her. She was charged with making written threats of violence, and the case is scheduled to go to court in November.Anthropic's consumer terms explicitly reserve the right to "decide on their own" to report user inputs, outputs, or behaviors to law enforcement. Its privacy policy, effective September 10, 2026, also allows the company to share data with police when it reasonably believes that disclosure is necessary to prevent serious harm. Even if users choose not to use their data for model training, Anthropic can still use their data within three months, rather than five years; conversations flagged for review will also be used to improve harmful content detection capabilities.This is not the first case. The San Francisco Standard reported in September that Anthropic had referred a user to the police, who allegedly wrote that they purchased an AR-15 rifle and had the company's CEO Dario Amodei in their sights, claiming it was just a joke. At the time of the report, the user had not been arrested or charged, and an Anthropic spokesperson stated that this was "our protective process working as intended."

According to Cointelegraph, Japanese investment and Bitcoin treasury company Metaplanet announced a revised capital allocation policy, proposing to invest 10% to 15% of total assets into strategic investments, including mergers and acquisitions and income-generating assets. It also launched a net interest income strategy to allocate capital to income-producing assets, using net interest income to support Bitcoin accumulation and dividend payments. Bitcoin remains its core treasury reserve asset, accounting for 85% to 90% of total assets. The company stated that this move aims to enhance financing capability and credit quality to increase the Bitcoin holdings per share.As this financing model was introduced, shareholders expressed concerns about Metaplanet's governance and complex capital structure. The company released five corrected securities filing documents last Friday, clarifying that CEO Simon Gerovich does not hold a majority voting power in Metaplanet shareholder MMX Ventures.Anonymous shareholder Bitcoin Pharaoh subsequently called for the company to clearly disclose the ownership of MMX Ventures, explain the 23.8% shares registered as indirectly held by Gerovich, and reveal the identities of two unnamed executives who exercised 18.8 million shares from the 10th stock option pool.In early September this year, management faced criticism from shareholders for expanding the 10th executive stock option pool from 46 million shares to nearly 319.5 million shares. On September 11, Metaplanet proposed to reduce the option pool by 41%, decreasing potential shares by 131.3 million to 188.19 million shares, and resetting the conversion ratio from 1:696 to 1:410.

According to The New York Times, the previous collaboration between NBA superstar LeBron James and the prediction market platform Polymarket, worth $15 million, has drawn attention. However, there is currently no evidence that this collaboration violates NBA rules. LeBron James is merely a spokesperson and not an investor, and the collaboration will focus on non-NBA markets such as soccer, thus it is not similar to the previous salary violation incident involving Kawhi Leonard with the Los Angeles Clippers.However, as the commercial ties between players, teams, investors, and prediction market platforms deepen, sports leagues face new regulatory challenges: how to distinguish between legitimate commercial endorsements and potential conflicts of interest that could affect market fairness.

The Rollup founder Andy posted on the X platform stating "POLY is coming," hinting that the Polymarket token POLY is about to launch.The accompanying image shows a post from Polymarket founder Shayne Coplan, who indicated that he might share news on the related topic at the TOKEN2049 conference in Singapore. Andy's post did not disclose the token issuance time, allocation plan, or airdrop details.

Bitcoin analyst Willy Woo stated on platform X that approximately 5% of the global population holds Bitcoin, while about 8% of countries have established policies for purchasing or holding Bitcoin.In a follow-up response, he added that around 12% of countries actually hold Bitcoin and distinguished between actual holdings and the proactive establishment of policies for purchasing and holding.

According to Cointelegraph, the advocacy organization focused on Zcash, Pretty Good Policy for Zcash (PGPZ), has submitted a lobbying registration, with the registration effective date of October 1. Executive Director Divij Pandya is the sole registered lobbyist. This move indicates that this privacy-oriented cryptocurrency ecosystem is intensifying efforts to influence U.S. digital asset policy.The registration documents include the Digital Asset Market Clarity Act and two digital asset tax proposals as part of its current and anticipated lobbying agenda. PGPZ was established in June of this year, evolving from the Pretty Good Policy for Crypto initiative launched by Electric Coin Co. in 2022, which held a Washington policy roundtable and organized a congressional briefing on cryptocurrency technology in 2023.PGPZ founder and ZODL Chief Policy and Regulatory Officer Paul Brigner stated that the goal is "to ensure that Zcash has serious, organized, and credible policy participation in Washington." He noted that the decisions being made by policymakers will affect whether privacy-preserving digital cash can exist, be used legally, and serve the public interest. PGPZ's responsibility is to ensure that Zcash is understood, represented, and defended in these discussions. In August of this year, Zcash Community Grants approved a $750,000 grant to fund PGPZ's work for its first year.

According to Bitcoin.com, the Brazilian presidential election will be held on October 4, and the results may influence the direction of the country's cryptocurrency policies, which have the highest global adoption rate. Current President Lula will face off against former President's son Flavio Bolsonaro.If current President Lula is re-elected, it is expected that he will strengthen regulatory and compliance requirements, as the central bank has intensified oversight of exchanges and may push for taxation on stablecoin transactions (which had been postponed due to the election). If former President's son Flavio Bolsonaro wins, his stance on cryptocurrency is unclear, with no record indicating that he has ever mentioned cryptocurrencies. However, he has previously defended individuals associated with the "Bitcoin Pharaoh" pyramid scheme.

According to Decrypt, the European Union's law enforcement agency reported that Spanish police arrested a 16-year-old Romanian suspect in Alicante, suspected of being an administrator and main operator of the ransomware group KillSec.Two other suspects in their twenties were arrested in the UK and Romania, respectively; another developer who just turned 18 in August this year has been identified but has not been arrested due to some crimes occurring during their minor years.This operation, codenamed Operation KillSwitch, was led by the Hamburg State Criminal Police and the city's prosecution office, focusing on approximately 1,000 suspected attacks worldwide, with about 500 confirmed as successful intrusions.Law enforcement searched eight locations in Spain, Greece, Romania, and the UK, seized five central servers, and redirected related domain names to seizure announcement pages, while also confiscating at least 110 TB of stolen data.KillSec has been active since around 2024, exploiting software vulnerabilities and poorly secured cloud storage entry points to infiltrate corporate systems, copying internal data and naming victim organizations on dark web leak sites, threatening to publicly release documents to demand cryptocurrency ransoms, and if the target refuses to pay, they release the data for free.The Swiss Federal Police noted that the group also employed double extortion tactics, first encrypting servers and then applying pressure. U.S. prosecutors' charges indicate that a Dutch national residing in the UK, Fouad Eltibrizi (nicknamed Archduke), was indicted by a federal grand jury in Puerto Rico on September 16, subsequently arrested, and awaiting extradition, facing up to 10 years in prison. The European Cybercrime Centre, under the European Union Agency for Law Enforcement Cooperation, is assisting in tracing cryptocurrency funds and conducting digital forensics.
