Paul Sztorc’s Bitcoin Fork ECX Rips Past 25,000 Blocks in Just 13 Hours

Paul Sztorc’s experimental Bitcoin fork ECX advanced past 25,000 blocks in roughly 13 hours, averaging about 1.9 seconds per block. That cadence is orders of magnitude faster than Bitcoin mainnet and demonstrates ECX’s ability to stress-test block-production and consensus parameters. Rapid issuance inherently reduces per-block economic security and suggests centralized or automated block production, so it does not pose an immediate threat to Bitcoin without broader miner and ecosystem adoption. The key implication for Bitcoin is that such experiments highlight trade-offs between throughput and security and can create short-term confusion or replay risks if chains and services are not clearly segregated.
