Chainalysis plans to launch an on-chain tracking standard system, proposing an "address clustering ontology" to unify blockchain forensic methods

According to CoinDesk, blockchain analysis company Chainalysis has released a new methodological proposal aimed at establishing a unified on-chain fund tracking standard framework for law enforcement agencies and investigators, to identify address clusters and determine their possible control relationships.The proposal defines the on-chain analysis structure in the form of "ontology," focusing on systematically breaking down the currently unstandardized concept of "cluster" in the industry into wallet segments and functional roles, and describing on-chain relationships through a two-layer structure: the first layer defines the transaction graph structure, and the second layer assesses inference confidence.Chainalysis stated that the framework aims to enhance the interpretability and legal applicability of on-chain forensic methods, and is designed and validated based on its practical experience in relevant cases within the U.S. Department of Justice, including the analytical application in the mixing service Bitcoin Fog case.The company's Chief Scientist Jacob Illum pointed out that the goal of the proposal is to answer "on what evidence basis can these addresses be considered to belong to the same entity," while emphasizing that on-chain analysis itself cannot directly identify the ultimate user identity and still requires legal investigative methods combined with centralized entities such as exchanges.Chainalysis indicated that the standard proposal is currently open for discussion within the industry, hoping to promote the formation of more unified technical specifications for on-chain analysis methods in the fields of law enforcement and compliance.

Strategy remains unchanged, Bitcoin listed companies' net purchases dropped by 83% in a single week

According to SoSoValue data, as of 8 AM Eastern Time on June 29, 2026, the total net purchase of Bitcoin by global listed companies (excluding mining companies) for the week was $14.65 million, a decrease of 83% compared to last week.Strategy (formerly MicroStrategy) did not purchase Bitcoin last week. At the same time, Strategy announced two securities repurchase plans, each up to $1 billion, targeting Class A common stock and digital credit preferred stock led by STRC, with an annual dividend yield of 8% to 10%, aiming to optimize the capital structure without consuming existing dollar reserves. To fund the aforementioned repurchases and support daily capital expenditures, the board also approved a Bitcoin liquidation plan, allowing the company to generate up to $1.25 billion in additional revenue by selling Bitcoin to replenish dollar reserves, and to pay maturing preferred stock dividends and interest expenses (or to replenish dollar reserves after such payments) when management deems it more beneficial than issuing Class A common stock or other capital market transactions, as well as to provide additional funding support for the two repurchase plans (including related taxes and transaction fees). Although this move by MicroStrategy releases the liquidation authorization, it currently serves only as a reserve shield for repurchases, with actual "momentum not sold"; its core logic has shifted from the initial "aggressive expansion of the balance sheet" to the refined operational phase of "utilizing crypto assets to optimize equity capital structure and reduce the capital cost generated by high-yield stocks."The Japanese listed company Metaplanet did not purchase Bitcoin last week, marking ten consecutive weeks without purchases.In addition, two other companies purchased Bitcoin last week. Hong Kong's global digital health, consumer goods sales, and artificial intelligence computing power technology group CIMG announced that it has just completed the first phase of a large stock and warrant issuance, receiving $13.5 million paid in Bitcoin (207.7 Bitcoins at an average price of $65,000), bringing its total holdings to 937.7 Bitcoins; Brazilian Bitcoin company OrangeBTC announced on June 29 that it invested $4.9 million to purchase 74 Bitcoins at a price of $66,233, bringing its total holdings to 3,896 Bitcoins.As of the time of writing, the total amount of Bitcoin held by the global listed companies (excluding mining companies) in the statistics is 1,142,484 Bitcoins, an increase of 0.02% compared to last week, with a current market value of approximately $6.852 billion, accounting for 5.7% of Bitcoin's circulating market value.

The U.S. CLARITY Act is entering a critical two weeks, with multiple parties intensifying discussions during the Senate recess

According to Crypto in America, the U.S. Senate will recess until July 13, and the advancement of the CLARITY Act depends on the progress of behind-the-scenes coordination over the next two weeks. Staff from both parties, government officials, and industry stakeholders are working to resolve remaining differences, including reconciling text discrepancies between the Banking Committee and the Agriculture Committee, as well as reaching consensus on ethical standards and provisions to combat illegal financial activities.The bill requires the support of at least 60 senators to pass. Even if all 53 Republican votes are in favor, at least 7 Democratic senators will need to join; the support of the majority of Democrats may depend on whether the White House can agree to establish a strong ethical framework regarding issues related to Trump's cryptocurrency business. According to Reuters, since Trump's return to the White House, his cryptocurrency business has generated over $2 billion in new wealth for him.Additionally, major law enforcement groups still oppose the inclusion of provisions from the Blockchain Regulatory Certainty Act in the bill, arguing that it would increase the difficulty of investigating and prosecuting on-chain crimes. Remaining discrepancies in the Agriculture Committee's text include issues such as the prioritization of federal law over state law, management of conflicts of interest in exchanges, and restrictions on related-party transactions. Sources indicate that the parties have not yet reached a final agreement, and there remains uncertainty about whether the Senate vote can be completed before the August recess.
