Everything you need to know about initial coin offerings

A tech company you’ve never heard of raised more than $150 million last week—in just three hours.

It was yet another initial coin offering (ICO), a new method of raising funding that has exploded in popularity for businesses in the cryptocurrency space.

The Bancor Foundation raised $153 million worth of ether (the digital token of the blockchain network Ethereum) in exchange for its own token, BNT. The company’s plans are vague, but it says its tokens will facilitate smart contracts.

Bancor’s ICO was the largest yet (based on the price of ether at the time) but not the fastest: that title goes to Brave, a new web browser from the former CEO of Mozilla (maker of Firefox) that seeks to use digital tokens as a method of micro-payment for online content. Brave raised $35 million worth of ether last month in exchange for its own “Basic Attention Tokens,” and it sold out of the tokens in 30 seconds. And SONM (Supercomputer Organized by Network Mining), an Ethereum-based cloud computing network, raised $42 million in its ICO last week.

Forget venture capital, forget the IPO, the hottest new way to raise money is the ICO.

How does an ICO work?

It started with Ethereum, a blockchain network designed for smart contracts.

Blockchain technology originated with the digital currency bitcoin in 2009—a decentralized, permissionless ledger that permanently records all bitcoin transactions. But now there are applications of blockchain cropping up that have nothing to do with bitcoin. Ethereum is one of them: it runs on its own blockchain and is meant for smart contracts, which are coded agreements that live in a permanent spot on the Ethereum chain. These agreements can interact with other contracts to automatically enact functions. (For example, I could sell you the deed to my car over Ethereum.) Ether is the digital token of Ethereum.

TechCrunch writes that Ethereum is “poised to overhaul open-source development.” And there are even implications very relevant to global politics at the moment: 23-year-old Ethereum founder Vitalik Buterin met with Vladimir Putin this week. Putin reportedly had big praise for Ethereum.

Ethereum launched in July 2014 through its own ICO, though that term wasn’t widely used yet: it sold about 60 million ether tokens and brought in $18.5 million worth of bitcoin. To be clear: participants bought ether and paid for it in bitcoin.

Now scores of blockchain-based startups are using an ICO to create and distribute their own digital tokens. Many of them are choosing to do their ICO via Ethereum—either because of the excitement over smart contract applications on Ethereum, or because the price of ether is up 130% in the past month, to $350.
