What Has Blockchair Highlighted About Bitcoin’s Security Budget?
Blockchain explorer and analytics firm Blockchair recently launched Budget.Day, a website designed to raise awareness and foster discussion about Bitcoin’s declining security budget, an issue that could threaten the network’s long-term viability. The platform presents simplified, live visualisations to help users understand how Bitcoin’s security is funded through a combination of block subsidies and transaction fees. With the block subsidy halving every four years and the fee market still underdeveloped, Budget.Day highlights the growing risk of insufficient miner incentives, which could expose the network to potential 51% attacks. The site also explores potential responses, from scaling solutions to controversial proposals such as modifying the 21 million BTC supply cap. By addressing widespread misconceptions, such as relying on hashrate growth or optimistic price projections, Blockchair aims to promote a more informed, solutions-oriented debate about Bitcoin’s future security.
