A growth in “non-fungible tokens”, or NFTs – tradable tokens based mostly on the identical know-how as cryptocurrency – is remodeling the artwork market.

With this progress has come renewed scrutiny, with critics attacking Bitcoin specifically as a speculative bubble that makes use of huge quantities of electrical energy and produces no actual worth.

A brand new cryptocurrency referred to as Chia, which has simply begun buying and selling, units out to treatment these flaws whereas upholding cryptocurrency’s promise of a safe, decentralized type of fee.

Chia is the brainchild of Bram Cohen, who invented the BitTorrent peer-to-peer filesharing system. He claims it is going to be extra dependable than different cryptocurrencies, and extra environmentally pleasant too.

Chia runs on a system that ought to use much less vitality, referred to as “proof of house and time”. On this system, customers want to indicate they’ve reserved a certain amount of exhausting drive house at a exact time.

So Chia received’t use large quantities of electrical energy, and received’t see miners shopping for up each graphics card in sight. However the requirement for exhausting drive cupboard space might result in different drawbacks.

Laborious drive worth surge

Even earlier than its official launch, Chia has used greater than an exabyte of information storage. That’s the equal of about one million of the 1 terabyte exhausting drives you may discover in a median desktop laptop.
