Jack Dorsey’s Block Launches Bitcoin Proof-of-Reserves to Boost Transparency

Highlights:

• Block now lets users verify its Bitcoin reserves through public proof-of-reserves checks.
• The company shows 28,355 BTC across customer holdings and corporate Bitcoin investment.
• Block also added new Bitcoin tools for Cash App, Square, and Bitkey users.

Block, the financial technology company led by Jack Dorsey, has launched a public proof-of-reserves (PoR) system for its Bitcoin holdings. The move, announced in Las Vegas on Monday, allows anyone to independently verify the company’s Bitcoin reserves using cryptographic proof. Block stated that people should not only trust that Bitcoin is held safely. They should also be able to check it themselves.

PoR is a method used in the crypto industry to show that a company holds the assets it claims to hold. For Bitcoin, this can be done by using blockchain data and signed messages from wallets. Block said its reserves should be open because Bitcoin itself runs on an open network. The company’s PoR page also notes that the dashboard is a point-in-time snapshot of holdings, not a full audit or guarantee of solvency.

That difference is important. PoR can show that Bitcoin exists in certain wallets and that a company controls those wallets. However, it does not always show every liability or financial obligation a company may have.

Still, the move gives users and investors more visibility into Block’s Bitcoin position. It also fits with the company’s long-running Bitcoin strategy under Dorsey, who has often supported Bitcoin-focused products and open financial tools.

The company now shows it holds 28,355 BTC in total, worth about $2.2 billion. This includes 19,357 BTC belonging to customers and roughly 9,000 BTC held by Block as a corporate investment. All figures were last verified in March as part of the Q1 report. Block published the data on its dedicated PoR page, where users can run verification checks directly in their web browser without sharing any personal data.

Block Adds New Bitcoin Tools for Users

Block’s PoR comes as part of its Bitcoin efforts. It also launched Bitkey, a touchscreen hardware wallet for users to securely verify transactions. Cash App also allows users to automatically receive part-payments in Bitcoin. Square sellers can also give customers 5% Bitcoin rewards. Block has also increased Bitcoin withdrawal limits to $10,000 a day and $25,000 a week. 

Jack Dorsey has been a Bitcoin advocate for a long time. He believes it can be used for free, peer-to-peer payments. Block wants to increase transparency and provide an example for other Bitcoin holders by making its Bitcoin reserve transparent. 

Proof-of-Reserves Became More Important After FTX

PoR gained wider attention after the FTX collapse nearly four years ago. It eroded confidence in the cryptocurrency industry and led many platforms to provide more evidence that user assets were secure.

A number of leading cryptocurrency exchanges, such as Binance, Kraken, OKX, Bitfinex, and Bitget, subsequently began publishing proof-of-reserves reports. Block is now taking the same step with its Bitcoin-focused services and corporate assets.

But others in the industry don’t support this approach. Some believe that data related to public reserves can be dangerous, as it can reveal wallet details. Supporters believe it improves trust because users can verify funds directly instead of relying only on company statements.
