Block Enhances Bitcoin Transparency with New Proof-of-Reserves Framework

Block has officially launched a proof-of-reserves mechanism, allowing the public to independently verify the company's Bitcoin holdings via on-chain signatures. This initiative covers the corporate treasury as well as the company's Square and Cash App platforms, joining a trend of crypto-adjacent firms seeking to prove their solvency on-chain. The move comes as a response to the industry-wide push for transparency following the 2022 collapse of FTX. By enabling verification, Block aims to remove the need for blind trust in corporate balance sheets, asserting that its reserves are actively controlled rather than merely observed. Block's treasury currently holds 8,883 Bitcoin, valued at approximately $681.4 million, making it the 14th largest corporate holder of the asset globally. This transparency effort contrasts with the approach of other major holders, such as MicroStrategy, where leadership has previously cited security risks associated with proof-of-reserves, arguing that such disclosures could expose sensitive information. Alongside the transparency update, Block introduced several Bitcoin-centric features to drive mainstream adoption. These include the Bitkey hardware wallet featuring a touchscreen for transaction verification and a new auto-conversion feature for specific Cash App users. To further integrate Bitcoin into daily commerce, Block is now offering 5% Bitcoin cashback rewards at Square merchants. Additionally, the company has significantly increased customer withdrawal limits to $10,000 per day and $25,000 per week to facilitate higher liquidity for its users.
