MARA Launches Bitcoin Foundation Targeting Quantum Risk and Miner Revenue Cliff
MARA Holdings CEO Fred Thiel announced the formation of the MARA Foundation at the Bitcoin Conference in Las Vegas on April 27, 2026. MARA, a bitcoin mining and infrastructure company formerly known as Marathon Digital Holdings before its August 2024 rebrand, is committing dedicated nonprofit-adjacent resources toward protecting Bitcoin's protocol from two compounding threats: quantum computing vulnerabilities and a long-term structural decline in miner revenue.
The foundation is structured as a nonprofit-adjacent initiative distinct from MARA's corporate mining operations. It will focus on five areas: network security research (including quantum resistance), open-source software development, self-custody tools, public policy and regulatory advocacy, and multilingual education for users, developers, and policymakers. As an initial commitment, MARA is directing $100,000 to one of three shortlisted nonprofit organizations, with the recipient chosen by community vote at the Bitcoin Conference.
The Quantum Problem Is No Longer Theoretical
The foundation's quantum focus arrives at a moment when the threat has moved from hypothetical to demonstrable. In April 2026, independent researcher Giancarlo Lelli broke a 15-bit elliptic curve cryptographic key using publicly available quantum hardware, collecting a 1 BTC bounty from quantum security firm Project Eleven. Elliptic curve cryptography is the same underlying system protecting Bitcoin wallets. Approximately 6.9 million BTC, roughly one-third of all bitcoin ever mined, sits in wallets where the public key is already permanently visible on-chain, making those funds theoretically vulnerable to a sufficiently powerful quantum computer. That figure includes an estimated 1 million BTC widely attributed to Satoshi Nakamoto, minted during Bitcoin's early days when public key exposure was standard practice.
Concerns about the timeline have spread beyond the crypto community. In an April 7, 2026 report by CoinDesk, a Nobel Prize-winning physicist warned that practical quantum computers capable of breaking current encryption are closer than many assume, adding scientific weight to the concerns animating the foundation's work.
Crypto researcher Nic Carter put it bluntly: "Elliptic curve cryptography is on the brink of obsolescence." Blockstream CEO Adam Back has argued that "Bitcoin should prepare with optional upgrades built in advance rather than scrambling during crisis." A Coinbase advisory board report, co-authored by Stanford cryptographer Dan Boneh, Ethereum Foundation researcher Justin Drake, and Eigen Labs researcher Sreeram Kannan, concluded that "a future fault-tolerant quantum computer capable of breaking widely used encryption is increasingly plausible. Waiting for it to be urgent is not a good idea."
The MARA Foundation intends to actively back BIP 360, a Bitcoin Improvement Proposal also known as Pay-to-Merkle-Root (P2MR). Published on February 11, 2026, and already merged into the official Bitcoin repository, BIP 360 proposes a new output type that eliminates the quantum-vulnerable keypath spend present in current Taproot addresses. Two of its three co-authors, MARA senior protocol engineer Hunter Beast and market strategist Isabel Foxen Duke, are MARA employees; the third co-author is cryptographic researcher Ethan Heilman. Bitcoin currently has no formal governance process for network-wide cryptographic upgrades, unlike Ethereum, which has run a post-quantum migration program since 2018.
The Revenue Problem Is Already Here
The foundation's second major focus is what researchers call the "security budget" problem. Following the April 2024 halving, Bitcoin's block reward dropped to 3.125 BTC per block, generating roughly 450 new BTC per day. Transaction fees currently represent about 15% of total miner revenue, below the 20%-plus threshold many analysts view as a sustainable replacement for block subsidies. The next halving, expected in April 2028, will cut the subsidy to 1.5625 BTC per block. Bitcoin Core developer James O'Beirne has warned that "we might have only two halvings left before this becomes a serious issue." Analysts warn that a shrinking security budget reduces miner incentive, which in turn reduces hashrate and weakens Bitcoin's resistance to 51% attacks. The MARA Foundation plans to research and advocate for a healthier transaction-fee market as a core mandate.
Thiel called Bitcoin "the most important decentralized system ever created," adding that "its future is not certain and requires active stewardship." He continued: "Decentralization doesn't mean it runs on itself. It means responsibility is distributed."
What This Means Outside the United States
Both threats carry outsized consequences for Bitcoin users in high-growth emerging markets. Sub-Saharan Africa processed more than $205 billion in on-chain value between July 2024 and June 2025, a 52% year-over-year increase, with Nigeria and Ethiopia both ranking in the top 15 of the 2025 Chainalysis Global Crypto Adoption Index. Stablecoin adoption in the region surged 180% year over year over the same period, driven largely by remittances and cross-border trade. South Asia, the fastest-growing crypto adoption region globally, posted 80% year-over-year adoption growth in 2025, generating roughly $300 billion in transaction volume, with India leading the 2026 index. Many users in these regions hold bitcoin in older wallet formats, including old P2PK or reused P2PKH addresses, that would be among the most exposed if a quantum attack materializes before a migration path is ready.
The foundation's multilingual education pillar and self-custody tooling work are directly relevant to these markets, where mobile-first users often rely on custodial wallets simply because hardware wallets and technical documentation are inaccessible. MARA already operates energy infrastructure in Ethiopia and the Middle East, giving it geographic footing in the region, though the company has not announced specific Africa-focused programs under the foundation.
The security budget issue also hits differently in price-sensitive markets. High-frequency, low-fee peer-to-peer transactions common in South Asian and African Bitcoin economies contribute minimally to miner revenue. Structural fixes, including transaction batching and broader layer-2 adoption, are worth early attention from regional Bitcoin advocates who want the base layer to remain secure.
What Comes Next
MARA Holdings itself is in the middle of a strategic pivot. In March 2026, the company sold 15,133 BTC for approximately $1.1 billion, using the proceeds to retire debt and fund a partnership with Starwood Capital Group targeting 1 gigawatt of digital energy infrastructure capacity. The sale drew down holdings from a mid-2025 peak of approximately 50,639 BTC. The launch of a Bitcoin-focused foundation, funded separately from corporate operations, suggests that MARA sees protocol-level work as part of its long-term positioning, even as its core business model continues to shift.
