Bitcoin to drive market for specialised parallel processors

Bitcoin is seen to pave the way for an emerging market for specialised parallel processors. This is according to a veteran high-tech investor. However, one young startup engineer is not bought on the idea.

"There's a big opportunity in silicon with a new wave of chip design ideas, which is not something we would have predicted a year ago," said Marc Andreessen co-founder and principal of Andreessen Horowitz.

Bitcoin is an online alternative to currency and banking that requires specialised silicon. This kind of "crypto currency is the first thing like the Internet since the Internet," said Andreessen in an on-stage talk at the Open Compute Summit.

Crypto currency is the first practical way to do business over the Internet with no central hub or trust authority needed to validate a secure transaction. It seems like a very, very big opportunity because it will be used by everything from big stock exchanges to services such as AirBnB sending electronic room keys back and forth for individual locks.

The approach requires a form of highly parallel computing called mining. "Mining is a very specific thing that can use parallelism, so I think custom chips for it will be around for a while; we're already seeing pitches for bitcoin-optimized data centers," he stated.

Thomas Sohmers, a 17-year-old wiz kid and chief executive of a high-performance server startup, said he has explored the technology and is not interested in it. "It's a kind of Ponzi or pyramid scheme where the people who get in first reap the most rewards," said Sohmers on the show floor of the OCP event.

Sohmers persuaded one of his partners to give up pursuing the technology, which uses silicon dedicated to the SHA-256 encryption algorithm.

"It's the biggest waste of processing power in the world," said Sohmers, whose startup, Rex Computing, is building servers using FPGAs and accelerators from Adapteva and others. "There are already ASICs out there for bitcoin mining," he noted, citing Butterfly Labs.

Bitcoin was used for the illicit Silk Road operation and speculators, but lacks legitimate uses, Sohmers said. However he noted that online tech shop Tiger Direct recently announced it will accept bitcoin.
