Block launches on-chain proof-of-reserves for payments platforms and discloses 28,355 BTC in Q1

Block has launched a bitcoin proof-of-reserves project covering its corporate Bitcoin reserves and core platforms, including Cash App and Square, enabling on-chain verification of assets and reflecting a broader industry trend toward greater transparency ^[1].

As part of that initiative, Block published a proof-of-reserves dashboard and disclosed total holdings of 28,355 BTC in its Q1 reserves report, a figure reported by multiple outlets covering the disclosure ^{[2] [3]}.

The Q1 snapshot, reflecting balances as of March 2026, showed Block added 114 BTC to its corporate treasury in the quarter and reported roughly 8,997 BTC in the corporate treasury alongside additional customer-held balances that together produced the 28,355 BTC total, valued at about $2.2 billion in reporting ^[3].

Block framed the proof-of-reserves rollout alongside continued product efforts to expand bitcoin use in payments, noting merchant adoption milestones as part of its broader push to integrate bitcoin across its services ^{[1] [4]}.

The proof-of-reserves dashboard provides an on-chain audit mechanism for stakeholders and accompanies Block’s ongoing bitcoin integration; the published figures reflect the company’s reported balances as of March 2026 ^{[1] [3]}.
