Strategy, Strive, and other Bitcoin treasury companies support the purchase of 135,979 Bitcoins through preferred stock financing, accounting for over 0.5% of the maximum Bitcoin supply; the related preferred stock market size is approximately $12 billion. Perpetual preferred stock has no fixed maturity date, which can alleviate refinancing pressure and attract income-oriented investors who are unwilling to hold Bitcoin directly; however, an increase in issuance size will also raise dividend expenses.Continuous financing for Bitcoin purchases relies on preferred stock trading at or near par value. If the price falls below par, the attractiveness of new issuances may decline, and the company may also turn to buybacks. CoinShares Research Director James Butterfill stated that Strategy's latest weekly report shows the company spent $193 million to repurchase STRC, while simultaneously buying 267 Bitcoins and increasing the preferred stock buyback authorization limit to $3 billion. Buybacks can reduce future dividend costs but may also compete for funds with Bitcoin purchases.Bitwise Research Director Ryan Rasmussen expects that ETFs will remain a larger source of Bitcoin demand in the long term, while perpetual preferred stock covers different groups of income-oriented investors, providing another source of demand support for the market. Butterfill believes that preferred stock may amplify market cycles: when financing conditions are favorable, it supports Bitcoin purchases, but when market sentiment weakens, this support may diminish.

According to CoinGlass data, the Coinbase Bitcoin premium index has recorded negative values for 31 consecutive days, with the latest at -0.1353%, indicating that purchasing power in the U.S. market has once again fallen into a slump.Previously, on August 24, the Coinbase Bitcoin premium index reappeared with a positive signal for the first time since May 19, reporting at 0.0052%, momentarily ending the longest historical negative premium period of 97 days. The Coinbase Bitcoin premium index is used to measure the price difference of Bitcoin between Coinbase Pro and Binance. A sustained negative index typically means that Coinbase's pricing is relatively low, which may reflect weak buying interest or significant selling pressure in the U.S. market, but it is not advisable to directly conclude that institutional funds are flowing out based solely on this indicator.

According to Coinglass data, in the past hour, the total liquidation across the network was 192 million dollars, with long positions liquidated at 184 million dollars and short positions liquidated at 8.4157 million dollars.Among them, in the past hour, the liquidation amount for BTC was 57.7 million dollars, and for ETH, it was 52.76 million dollars. Additionally, NEAR had a liquidation of 13.02 million dollars.

According to Coinglass data, if Bitcoin falls below $79,000, the cumulative long liquidation intensity on major CEXs will reach $855 million. Conversely, if Bitcoin breaks above $82,000, the cumulative short liquidation intensity on major CEXs will reach $519 million.The liquidation chart does not show the exact number of contracts to be liquidated or the exact value of contracts being liquidated. The bars on the liquidation chart represent the significance of each liquidation cluster relative to nearby liquidation clusters, that is, the intensity. Therefore, the liquidation chart shows the extent to which the underlying price reaching a certain position will be affected. A higher "liquidation bar" indicates that once the price reaches that point, there will be a stronger reaction due to liquidity waves.

Succinct's zero-knowledge proof system SP1 has revealed a high-severity reliability vulnerability. This vulnerability was disclosed through GitHub announcement GHSA-p7v2-jjv3-8p8f, affecting SP1's native Rust verifier versions 6.0 to 6.8.0, allowing the mainnet Prover Network to potentially accept invalid proofs: malicious provers can submit proofs of invalid executions, and the network verifiers will still accept them.The cause of the vulnerability is that the verifier only reads the labels of the data (declaration dimensions) without verifying whether the actual number of stored elements equals the product of the dimensions, allowing attackers to forge labels to pass invalid proofs. The Groth16 and Plonk checks using fixed-shape wrap proofs are unaffected, and the on-chain Solidity checker is also safe. Succinct released the fixed version 6.8.1 on September 24, which has been deployed to the mainnet; this version adds deserialization length checks.The vulnerability was discovered by Vitalis Salis and reported through the Immunefi bug bounty program. Users running the native Rust verifier and accepting untrusted provers need to upgrade to 6.8.1.

Initia posted on platform X that on October 23 at 22:59 (UTC+8), attackers exploited a caching vulnerability in the Initia MoveVM script to bypass security checks, forging MoveVM states to credit themselves with unsupported WETH, iUSD, and USDC, while the total supply of the related tokens remained unchanged; INIT was not minted, and the total supply was unaffected.Before the network was paused, the attackers had transferred out approximately $2.7 million in assets, including 105 WETH transferred via LayerZero and about 1.4 million AUSD0, as well as approximately 1.08 million USDC transferred via Noble and CCTP, which were then exchanged for 1135.52 ETH, currently held at the Ethereum address 0x358ef0130f7a5aa516dcd81bdc80b18cde41cac8. Initia stated that the security fix is expected to be completed and audited within a few days, and asset recovery efforts are being advanced with security partners. L1 and Rollup remain in a paused state, and a complete post-mortem report will be released subsequently.

The innovation exemption for tokenized securities trading venues launched by the U.S. SEC in September is sparking controversy within the industry regarding blockchain qualification standards. This exemption allows eligible companies to trade tokenized U.S. stocks without registering as traditional securities exchanges, but requires their smart contracts to be auditable, public, and deployed on a public, permissionless blockchain.Currently, three companies have submitted operational intent notices to the SEC. TSV LLC plans to use the privacy-focused Canton Network; OKXICE and Kephas Corp. intend to utilize their respective enterprise group's developed Ethereum Layer 2 networks.In a letter submitted on Thursday, the Solana Policy Institute requested the SEC to tighten the definition of "permissionless," focusing on who actually controls the blockchain, including who can validate or block transactions and modify network rules. Hedera advocates for an expansion of the exemption's scope, arguing that only authorized entities should participate in validation, which should not disqualify their network.The Securities Industry and Financial Markets Association (SIFMA) also called for clarification on which blockchains are eligible and questioned whether stock tokenization should require explicit prior consent from the issuing company, rather than requiring companies to opt out. The financial regulatory advocacy group Better Markets urged the SEC to withdraw the exemption and instead engage in formal rulemaking.An SEC official stated that companies can begin operations 30 days after submitting a notice, provided they meet the exemption criteria, without waiting for SEC approval, which does not imply SEC endorsement of their chosen blockchain. The official noted that the regulatory agency intends to maintain a broad definition to allow space for companies to experiment; further frequently asked questions may be released, but substantive adjustments would require action from the commission.Meanwhile, more companies are opposing the tokenization of their stocks. As of Friday, among the 62 companies initially listed by OKXICE, 22 have raised objections, exceeding one-third. New objectors include Wells Fargo, Arm, and Intuit.

According to Unchained, the Ethereum liquid staking protocol Swell has suspended the deposit and withdrawal services for swETH and rswETH, which will be resumed after correcting the net asset value (NAV) and exchange rate of the two tokens.Currently, the project team has not announced a specific recovery time and stated that user funds are safe.
