Bob Burnett, CEO of Barefoot Mining—a company specializing in off-grid “wild” Bitcoin mining services—has made a provocative claim: future wars will be fought over Bitcoin blockspace. In a recent interview on the Bitcoin Fundamentals podcast, Burnett argued that as Bitcoin integrates deeper into the global economy, the value and scarcity of blockspace will rise to the level of a strategic resource, potentially triggering geopolitical and military conflicts.
The Scarcity and Financialization of Blockspace
Burnett explained that the current perception of a block’s value—simply the sum of transaction fees and the block subsidy—will fundamentally shift. In a world where Bitcoin is the base layer of money, major companies and sovereign states will require guaranteed access to the network at specific times to settle critical transactions. This need will transform blockspace into a finite, scarce asset. “If we’re on a path to Bitcoin being the base layer of money, now Bitcoin is existential to all the financial services companies and government. We can probably debate the time frame, but we are on a path where wars will be fought over control of those 53,000 blocks,” he stated.
He predicts that within the next 15 years, blockspace will become fully financialized. Mining companies will no longer rely solely on block subsidies and transaction fees. Instead, they will offer their “product”—blockspace—to the highest bidders, creating a futures market for blockspace. This market would stabilize mining revenue, as transaction fees would eventually outweigh subsidies. Burnett believes this financialization is the key to solving Bitcoin’s long-term sustainability problem.
Miner Cartels and Transaction Exclusion
Burnett also envisions the emergence of “cartels” of companies that form associations with mining organizations to gain preferred access to blockspace. Such consortia would only process transactions from their inner circle, rejecting bids from outsiders. This exclusivity would further intensify competition and drive up the strategic importance of blockspace. While this may sound dystopian, it reflects a logical extension of the current trend toward mining centralization and the rise of institutional involvement in Bitcoin.
Critics, however, dismiss the idea of wars over blockspace as overly dramatic. They argue that Bitcoin’s decentralized nature makes it difficult for any single entity to control blockspace, and that the network’s global consensus would discourage localized conflicts. Nonetheless, Burnett’s remarks have ignited a debate about the future of Bitcoin mining economics and the potential for blockspace to become a geopolitical asset.
Barefoot Mining operates in remote, off-grid locations, providing “wild” mining services that are resilient to power grid disruptions. Burnett’s perspective comes from a deep understanding of the mining industry’s edge cases. Whether or not his predictions materialize, the conversation highlights the evolving relationship between Bitcoin, energy, and global finance.
