TO SAVE MANKIND: PROPOSED IS AN ALTERNATIVE TO MINING BLOCKCHAINS

The concept of blockchains arouses an admiration due to its reasonableness and ease of implementation within existing infrastructure of Internet. The essential flawisan unacceptably big (from the point of view of ecology and common sence) power waste. The matter concerns the destinies of mankind, because uncontrollably expanding mining blockchains inevitably leads to overheating of Earth and thendeath of all living things. The solution being proposed is based on that follows: mining blockchains is not the goal in itself. The end goal is the reliable safekeeping of some valued constant (invariable) file. We propose not to RESIDE this file in the usual storage medium but to GENERATE it by a proper finite-state automaton. The principal singularity of the automaton circuit is an exeptional testability with respect to all multiple stuck-at faults. It is due to building the circuit according to the Theory of widened long flip-flop. The availis that mining is EXCLUSED as well as consumption of any significant power
