In the real world, this problem gets avoided with cash, which is quite difficult to counterfeit. In practice, digital counterfeiting is much easier. Satoshi's solution was what has become known as the blockchain: It's like a giant interactive spreadsheet everyone has access to and updates to confirm each digital credit is unique.
It is this technology that programmers are now working to deploy for uses that go far beyond Bitcoin. Satoshi does not appear to have been looking to solve this problem when he created Bitcoin. Satoshi and the blockchain really solved that problem in an elegant and unexpected way. The breakthrough means that, theoretically, any act of commerce on the Web can be decentralized and stripped of a controlling authority.
Perhaps the most straightforward example of a post-Bitcoin service using Satoshi's blockchain is Proof of Existence. Neither its contents nor your own personal information are ever revealed — rather, all the data in the document gets digested into an encrypted number. Proof of Existence is built on top of the Bitcoin blockchain there's a 0. A slightly more politicized application of the blockchain is a project called Namecoin. But three years ago, engineers developed Namecoin, which serves as a new domain-name system for registering Web addresses that end in ".
Again, blockchain technology makes it so that something that previously required a centralized authority can now be managed via community. You may have heard this before, but Luria explained why the blockchain is the true threat: Most processors use hub-and-spoke models, he said, which are able to charge fees for crossing jurisdictions, and for smaller transaction amounts.
Decentralizing and distributing the network gets rid of all that. A startup called Ripple represents the most active threat to the mega-processors.
We profiled Ripple, and the group that created it, last month. Computers all familiar with each other on Ripple's network mutually agree on changes to its blockchain Ripple calls it a "ledger".
This allows transactions to be processed instantly and without a third party. It's even faster than the Bitcoin network, because everyone using the Ripple ledger gets their own copy of the whole ledger, in contrast with the nodes on the Bitcoin network all sharing a single one. The blockchain is even stalking credit-card companies. Even sending money through Venmo, the app that lets you text your friends for picking up dinner that one time, still takes five days to clear.
Of course, it's possible the existing financial behemoths could adopt their own blockchain technologies. He calls such futuristic entities distributed autonomous corporations. To use the music example, Larimer envisions artists having the ability to issue shares in their own songs, encouraging fans to spread the tune far and wide to increase returns.

The Exponent Online 9 April Indeed, ICOs appear to be locked in something of a feedback loop with major cryptocurrencies — most notably, bitcoin and ethereum. A run-up in cryptocurrency prices this year has created paper gains for investors, many of whom have looked to diversify into ICOs. More available capital has also contributed to an increasing number of blockchain entrepreneurs opting to raise funds via ICOs as opposed to traditional equity financing, in turn fostering higher demand for cryptocurrencies broadly, and so on.
Cumulatively since January , the number of ICOs should surpass the number of equity deals in October , underscoring hype around the financing mechanism. Teams holding ICOs are building decentralized blockchain applications across verticals, ranging from asset management to social networks to prediction markets. Importantly, teams holding ICOs are adamant that they do not represent securities offerings — which would put them on the wrong side of the law — and instead market their coins or tokens as part of an entirely new asset class altogether.
For example, bitcoin is a token that provides ownership of a unit of account on the Bitcoin ledger. In the same vein, companies justify large pre-product ICOs by arguing that scarce tokens provide future utility within decentralized networks. Venture investing has shifted over time, with VCs first backing companies exploring bitcoin as currency, then focusing on private blockchain providers catering to financial services and other verticals, and today investing in the token economy.
The recent boom in cryptocurrencies and ICOs has had a material effect on the number of blockchain teams looking for financing, with traditional equity deals on track to set a new record of in , up from in VC-backed deals specifically should grow at a similar rate, to a run-rated 77 in Meanwhile the proportion of later-stage deals Series D and later this year is staying consistent with figures.
At the same time, given that ICOs currently account for the vast majority of blockchain seed deals, the sector is seeing a substantial uptick in seed-stage companies that are not represented in equity financing data. Looking at VCs and investments, the number of active VCs with at least one blockchain investment in a given year has hit 95 in YTD, setting them on pace to hit by the end of the year. This suggests VCs are showing renewed interest in the sector, after dropping steeply in
