Dogecoin developers spar over security model, reject claims of Litecoin dependence
Dogecoin developers and the community are arguing over the coin’s merged-mining security model. The dispute centres on whether Dogecoin depends on Litecoin for security or draws it from multiple merged-mined Scrypt-based layer-1 chains. Dogecoin Foundation developer Paulo Vidal questioned reliance on other blockchains, while developer Chromatic X said Dogecoin depends on all merged-mined Scrypt chains. Co-founder Billy Markus also weighed in. No conclusion has been reached on changing the structure.

Quantum computers breaking Bitcoin? Academia says sun-level energy needed, unlikely
Academic analysis says the quantum-computing threat to Bitcoin has been overstated, with mining-focused attacks requiring near-stellar energy output and impractical infrastructure. Recent studies argue quantum risks should be assessed separately for mining and wallets, with feasibility differing by target. Grover-based mining attacks would need immense computation within minutes, while Shor-based attacks could pose a longer-term risk to wallets, especially where public keys are exposed through reused addresses.

AI data centre boom raises concerns over Bitcoin network security
A surge in artificial intelligence data centres is fuelling debate over whether it will draw power and capital away from Bitcoin mining and weaken network security. Some experts warn that fewer miners could make Bitcoin more vulnerable to a so-called 51 percent attack. Others say Bitcoin adjusts mining difficulty and that profitability could improve. Industry examples include miners pursuing AI hosting and computing, while analysts differ on long-term implications.
