Block Launches On-Chain Proof-of-Reserves System
In a significant move towards increased transparency in cryptocurrency management, Block has launched an on-chain proof-of-reserves system that encompasses its Bitcoin holdings along with various consumer products. This initiative allows users to independently confirm Block’s Bitcoin reserves, leveraging cryptographic signatures published on the blockchain. Block emphasized that trust should not be required; instead, users should have the ability to verify that their Bitcoin assets are indeed secure.
Verification Mechanism and Industry Context
Disclosures from the company indicate that this new verification mechanism enables the validation of control over approximately 8,883 BTC, equating to around $681.4 million. Such a volume places Block among the most substantial corporate holders of Bitcoin in the industry. The company clarified that these reserves are actively managed, providing real-time verification instead of merely historical data snapshots.
The momentum towards adopting proof-of-reserves has noticeably increased following the FTX collapse in November 2022. In response, many exchanges began to publish their verifiable asset holdings to regain user trust. Competitors like Binance, Kraken, OKX, Bitfinex, and Bitget have embraced similar disclosure practices, striving for greater accountability in asset management.
Industry Concerns and Comparisons
However, the move isn’t universally endorsed within the industry. Michael Saylor, a prominent figure in cryptocurrency, cautioned against proof-of-reserves in May 2025, suggesting that making such data public could inadvertently compromise security by revealing critical wallet information. He argued that such practices could undermine the safety of not only exchanges and custodians but also investors themselves, branding the idea as fundamentally flawed.
Currently, MicroStrategy holds the title of the largest corporate Bitcoin holder but has refrained from adopting proof-of-reserves protocols, despite its larger BTC stake compared to Block.
Enhancements to Bitcoin Offerings
In tandem with its verification system, Block has enriched its Bitcoin offerings. This includes the launch of a revamped Bitkey hardware wallet featuring a touchscreen for easy transaction validation. Additionally, Cash App has rolled out a new option allowing select users to convert incoming payments directly into Bitcoin.
Merchant-related initiatives also saw enhancements, such as the introduction of a 5% Bitcoin cashback reward program for purchases made through Square, alongside increased withdrawal limits now allowing daily withdrawals of up to $10,000 and $25,000 weekly.
Future Plans and Vision
Furthermore, Block is revisiting its earlier plans to democratize Bitcoin access through a faucet model with the btc.day initiative, first mentioned in April 2026. While this strategy aims to facilitate education and onboarding reminiscent of the early distribution techniques employed by Bitcoin’s co-creator Gavin Andresen, specific details about the amount of Bitcoin to be distributed and eligibility criteria remain undisclosed.
Jack Dorsey, the company’s co-founder, has consistently advocated for Bitcoin as a payment network, suggesting that broader acceptance is crucial to realizing Satoshi Nakamoto’s vision for decentralized electronic cash.
