Google plans to showcase Google Multi-Party Compute, a security service for cryptocurrencies and tokenized assets, in New York City on Wednesday. Google plans a commercial launch in early 2027, following private testing by design partners and major financial institutions. Alphabet has begun using the technology to protect digital assets on Ethereum and Solana. The service distributes signing control to reduce risks from compromised credentials and unauthorized transactions, rather than breakthroughs against underlying cryptography. Google says future upgrades could support post-quantum cryptography, but Google has not provided a timetable.

Santiment data show Bitcoin holders moved a net 14,942 BTC off exchanges, the largest single-day outflow in 5 weeks, ahead of Wednesday's Federal Reserve decision. However, Arab Chain data show Binance Bitcoin futures traders favor shorts slightly, with about $4.11 billion in shorts against $3.91 billion in longs. Bitcoin gained 1.54% over the past 24 hours to $80,837, according to BeInCrypto Markets data. Markets expect the Fed to leave rates unchanged, although Morgan Stanley expects more signals of rate increases. Santiment identified $80,000 as the first support level, with a sustained hold and falling exchange supply favoring a rebound toward $82,500 to $84,000.

Bithumb said an unauthorized outside party entered the exchange's internal mobile groupware system and caused a personal information leak, according to Yonhap News Agency. Reuters, citing Yonhap, reported that Bithumb is investigating whether customer data was exposed. An industry source told Yonhap that some Bithumb customer information had leaked. Daishin Securities and Mirae Asset Global Investments also reported breaches on Wednesday, local time. Daishin said the breach exposed personal information belonging to 38,490 customers.

Bitget has published research with Reality and Keyring on tokenized stock basis strategies and plans an onchain stock basis trading strategy. Historical simulations covering December 15, 2025, to October 19, 2026, produced annualized net strategy index returns of approximately 7% in-sample and 4% out-of-sample. The report identifies financing costs, execution fees, liquidity and risk management as major influences on actual returns. Bitget and Keyring reportedly plan to develop a stock basis index together and establish an onchain lending market using Reality's rToken.

A DBS survey found that 88% of respondents represented large businesses with live deployments or pilots of tokenized money for cash management and cross-border payments. EY conducted the study for DBS, polling 422 business and finance leaders across 11 markets whose organizations had annual revenue above $500 million. The study found that 24% had implemented the technology at scale. Some 71% reported better real-time cross-border payments or expected improvements within two years. Regulatory uncertainty, security risks and integration difficulties remained barriers, and 64% wanted banks to offer one access point to the tokenized money ecosystem.

Mirae Asset Securities (HK) has issued a tokenized financing note using the Solana blockchain. The USD-denominated note has a six-month tenor and a floating interest rate. The note falls within a US$3 billion secured structured notes program, but that figure is the program's total size, not this issuance's value. Only professional investors meeting Hong Kong's Securities and Futures Ordinance requirements could participate through private placement. The Hong Kong Securities and Futures Commission has neither authorized nor registered the note.

On-chain detective Specter said the Bloom drainer stole nearly $1 million. The attacker routed funds through 2,152 distinct addresses used for routing and receiving funds. Transaction patterns suggest possible automation involving repeated fund splitting, consolidation and cross-chain transfers. The attacker also transferred funds to Zcash, where 26.099 ZEC entered the Sapling shielded pool.

Itaú Unibanco, Brazil's largest private bank, became the country's first bank to formalize crypto trading and custody under the new digital-asset rules. Valor Econômico reported that Itaú notified the central bank on Tuesday, before the October 30 compliance deadline. Eligible banks can notify the regulator rather than apply for operating authorization, which dedicated virtual-asset service providers must obtain. Institutions that miss the notification deadline must end crypto services within 30 days. Itaú has offered the service since December 2023 but has not disclosed customer counts or trading volumes.

SK Hynix shares rose 11% as artificial intelligence stocks continued recovering from several weeks of selling pressure. South Korea's Kospi gained 6.6% on Wednesday after SK Hynix delivered earnings above expectations and announced a substantial shareholder payout.

South Korea's KOSPI Composite Index gained 6.63% as technology stocks recovered from losses earlier in October. Crypto trader and analyst Rekt Capital said Bitcoin's weekly chart resembled the 2022 bear market, with uncertainty over whether a new trading range would form above resistance near $82,000.

Coinbase Global will release third-quarter earnings after markets close on Thursday, following losses in the first two quarters of 2026. Analysts expect revenue of $1.21 billion, more than 35% below the year-earlier quarter and roughly unchanged from the second quarter. Coinbase is expected to post a GAAP loss of $0.1 per share. Polymarket bettors assign a 95% probability to Coinbase beating that earnings expectation. COIN has a consensus Buy rating, but technical indicators give conflicting signals.

Japan Bitcoin Industry announced plans to raise approximately 800 million yen through a private placement funded entirely with Bitcoin.

Japan Bitcoin Industry also signed a routing cooperation framework agreement with ANAP Lightning Capital.

Delphi Digital's model puts the average wait for an institution-approved Ethereum proposer at four minutes when eligible operators hold 5% of proposer-selection weight. Ether.fi's April ETH commitment, valued at $3 billion at the time, could supply ETHGas's institutional blockspace service. However, usable capacity depends on the active stake that satisfies each customer's requirements, not the total number of participating validators. ETHGas advertises confirmations in about 50 milliseconds, but that speed does not establish immediate access to an eligible slot or final settlement. ETHGas's cumulative relay figures show activity without revealing current institution-qualified proposer weight.

The National Investigation Headquarters of South Korea's National Police Agency opened a pre-indictment investigation on the morning of October 28 into hacks affecting securities firms and crypto asset exchanges.

Anthropic's seven co-founders could hold stakes worth $189 billion to $203 billion combined if Anthropic reaches a $2 trillion valuation at its initial public offering. Benzinga, citing Anthropic's IPO filing and Fortune's calculations, reported that the co-founders together own about 1.69 billion shares, approximately 10% of Anthropic. The reported $2 trillion valuation is not included in the prospectus. The final offering price and post-IPO share count remain undisclosed. The filing identifies all seven co-founders as selling stockholders without specifying the number of shares each intends to sell.

Bitcoin gained an average of 53.7% during the 12 months following three previous US midterm elections, excluding 2010 because the market was too small. Historical patterns suggest cryptocurrencies and stocks could advance after the November 3 elections. However, bitcoin's limited history cannot establish firm conclusions, and the gains may reflect bitcoin's four-year cycle rather than politics. Hartford Funds puts the S&P 500's average post-midterm annual gain since 1950 at 15.17%, compared with 7.30% in other years. Democrats could intensify disputes over federal debt, defense funding and President Donald Trump's crypto interests if Democrats win either congressional chamber. Markets already largely reflect expectations of divided government.

Moody's Ratings awarded Ripple's dollar-denominated stablecoin RLUSD investment-grade deposit ratings of A2 for the long term and P-1 for the short term. Moody's said the assessment considers reserve quality, coverage, liquidity and redemption arrangements, among other factors. Moody's said Standard Custody & Trust Company targets reserve coverage of 103%, above the minimum associated with the rating. Ripple senior vice president of stablecoins Jack McDonald said RLUSD is the first stablecoin with an investment-grade rating from Moody's. RLUSD has reached a market capitalization of $2.5 billion.
