THELOGICALINDIAN - Three advisers accept appear a cardboard at Cornell Universitys arxivorg proposing a arrangement alleged Optical Proof of Work OPOW to potentially be active in Bitcoin mining According to the cardboard abundant assurance on electricity has created scalability issues ecology apropos and systemic risks The authors accompaniment that silicon photonics could be acclimated to about-face mining costs abroad from energyintensive to hardwarebased costs blurred the bread-and-butter and ecology appulse abacus greater aegis and democratizing mining

Optical Proof of Work
The arrangement proposed by authors Michael Dubrovsky, Marshall Ball, and Bogdan Penkovsky is described as “a atypical POW algorithm, Optical Proof of Work (OPOW), to annihilate activity as the primary amount of mining. Proposed algorithm imposes bread-and-butter adversity on the miners, however, the amount is concentrated in accouterments (capital expense-CAPEX) rather than electricity (operating expenses-OPEX).” In added words, the paper’s angle is that photonics could potentially accredit abundant added activity able mining, which ability accept a cardinal of furnishings on the industry.
The “Optical Proof of Work” paper states that “Rapid advance and advance in silicon photonics over the aftermost two decades has led to the commercialization of silicon photonic co-processors (integrated circuits that use photons instead of electrons to accomplish specialized accretion tasks) for low-energy abysmal learning. OPOW is optimized for this technology such that miners are incentivized to use specialized, energy-efficient photonics for computation.”
Many questions abide as to the proposed implementation, however, absorption on the bread-and-butter realities of bazaar antagonism and economies of scale, as able-bodied as changes at the algorithm akin which would charge to booty place. Also, although the angle is to accomplish mining accouterments abundant added specialized and difficult to acquire, different from arrangement to arrangement (to disincentivize risks like 51% attacks), footnotes in the cardboard accept there could be exceptions. “Although not impossible, a accommodating accomplishment to hire on the adjustment of bisected of the accouterments on a arrangement would be difficult to adumbrate and owners of accouterments accept an allurement not to hire to attackers, as the accouterments is acceptable to lose amount if the arrangement is attacked.”
Dubrovsky’s Thoughts on the Proposal
Michael Dubrovsky, Co-Founder of Powx, and one of the three advisers abaft the paper, aggregate some insights apropos the activity with news.Bitcoin.com via email, detailing: “Our aboriginal alive accomplishing will be with a accomplice arrangement that will alpha application OPOW Q1- Q2 2020. We’re acquisitive to see broader acceptance (eventually Bitcoin) afterwards the aboriginal accomplishing proves the concept.” When asked about how photonics ability affect antagonism in the industry, and whether ample mining operations wouldn’t artlessly use their accepted activity accommodation to ability alike added miners, he replied:
“There’s a area on this in the whitepaper but we go into it in added detail in our accessible bookish paper,” Dubrovsky elaborated. “We will absolution V1 in a few months. Heavyhash is not that complicated so it doesn’t crave a massive library of code. We’ll additionally broadcast dent architecture files for our prototypes.”
The cardboard describes heavyhash as a custom assortment action and states: “In its simplest form, OPOW is the Hashcash algorithm with our custom assortment function, Heavyhash, advised accurately to run calmly on optical accelerators while attention all POW-necessary cryptographic aegis properties.”
Some commenters on Dobrovsky’s Twitter column on the accountable accurate affair with a proposed about-face which, in the researcher’s words, would be a bendable angle to the absolute protocol. It’s bright that both protocol-level and bread-and-butter doubts remain, including questions apropos the absolutely new acreage of antagonism that would apparently be created for the best photonic chip, hardware, etc. Whether or not mining could anytime be democratized in the faculty of allowance “the little guy” charcoal to be seen, and alone the approaching will acquaint if photonics can absolutely accompany about cogent change in the bitcoin mining industry.
