The firm added that the reserves are \u201cactively controlled, not just historically observed,\u201d pointing to real-time verification rather than static snapshots.<\/p>\n<p>Adoption of proof-of-reserves gained traction after the collapse of FTX in November 2022, when several exchanges moved to publish verifiable holdings to reassure users about asset backing. Platforms including Binance, Kraken, OKX, Bitfinex, and Bitget have since implemented similar disclosures.<\/p>\n<h2 class=\"wp-block-heading\">Debate over transparency and security persists<\/h2>\n<p>Not all industry participants support the approach. Michael Saylor <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/x.com\/MitchellAskew\/status\/1927175496074182798?s=20\" target=\"_blank\" rel=\"nofollow\">said<\/a> in May 2025 that publishing proof-of-reserves can introduce security risks by exposing sensitive wallet data.\u00a0<\/p>\n<p>\u201cIt actually dilutes the security of the issuer, the custodians, the exchanges and the investors,\u201d he said at the time, adding, \u201cIt\u2019s not a good idea. It\u2019s a bad idea.\u201d<\/p>\n<p>    <!-- .cn-block-related-link --><\/p>\n<p>Strategy, the largest corporate holder of Bitcoin, has not adopted proof-of-reserves disclosures despite holding significantly more BTC than Block.<\/p>\n<p>Alongside the verification rollout, Block has expanded its Bitcoin product suite. The company introduced an updated Bitkey hardware wallet with a touchscreen for transaction verification, while adding a feature on Cash App that lets selected users automatically convert incoming payments into Bitcoin.<\/p>\n<p>Merchant-facing updates include 5% Bitcoin cashback rewards for purchases made through Square, paired with a fivefold increase in withdrawal limits to $10,000 per day and $25,000 per week.<\/p>\n<p>Earlier efforts by Block to widen Bitcoin access included plans to revive the faucet model through btc.day, a campaign first outlined in April 2026. Company updates tied the initiative to education and onboarding, echoing early distribution methods used in 2010 by developer Gavin Andresen, although Block has not disclosed how much BTC will be distributed or who will be eligible.<\/p>\n<p>Jack Dorsey has repeatedly framed Bitcoin as a payment network, stating in prior remarks that wider adoption is necessary to support Satoshi Nakamoto\u2019s original design for peer-to-peer electronic cash.<\/p>\n<p>    <!-- .cn-block-related-link --><\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Block has introduced an on-chain proof-of-reserves system covering its corporate Bitcoin holdings and key consumer products, expanding its push for transparency in digital asset custody.
