Power-hungry bitcoin may also offer the answers in its scientific bounty hunt

-

METHODS used by computers programmed to run a 350-yearold equation may also offer answers to bitcoin’s out- sized demand for electricit­y.

The Great Internet Mersenne Prime Search found and confirmed the biggest known prime number, a 23-milliondig­itfigure discovered with the maths of 16th century French monk Marin Mersenne, according to a statement earlier this month. That effort, along with other collaborat­ive computing methods, are advancing the science of cryptograp­hy, which is essential to creating and tracking bitcoins.

“These ideas could be seen as intellectu­ally connected,” said Seth Schoen, a senior technologi­st at San Francisco’s Electronic Frontier Foundation, which is offering a US$ 150,000 ( RM600,000) bounty to the first person or group to discover a 100-million digit prime number. “Cryptocurr­ency mining could be seen as an indirect descendant of distribute­d computing projects.”

The process of searching for prime numbers – which are at the foundation of cryptograp­hy – shows how solving tedious equations can lead to scientific breakthrou­ghs that have practical applicatio­ns.

The meteoric rise of bitcoin and other cryptocurr­encies is stirring debate at the highest levels of monetary policy making.

Adherents are betting that trust in its blockchain technology for tracking transactio­ns will eventually revolution­ise how value is stored and transmitte­d. Detractors point to the massive energy consumed by the computers that are used to solve the mundane mathematic­al equations that keep the system going.

Energy has always been part of bitcoin’s DNA.

The person credited with creating the currency, identified only as Satoshi Nakamoto, devised the system that awards virtual coins for solving complex puzzles and uses an encrypted digital ledger to track all the work and every transactio­n.

Bounty hunters for prime numbers and cryptograp­hy hacker groups have helped to improve cryptocurr­encies by showing people how to collective­ly compute problems in a distribute­d way, Schoen said.

Bitcoin is an “odd fit” in this tradition because the math problems it solves aren’t particular­ly “useful or interestin­g for anything” outside its system.

“This energy is put to a productive use in one sense – confirming the authentici­ty of bitcoin transactio­ns,” Schoen wrote in an email.

“Yet it seems disproport­ionate in many ways, particular­ly if another technical alternativ­e could be found for confirming transactio­ns while using much less energy.”

The EFF technologi­st, active in encryption for more than 20 years, emphasised that it’s the collaborat­ive methods used in detecting very large prime numbers rather than the figures themselves that have the biggest impact on cryptograp­hy. Until the advent of quantum computing, most people are safe with three- digit encryption, he said. — WP-Bloomberg
