Anthony Diiorio was involved with Ethereum from the earliest days. He was one of the first people to see the Ethereum ideas presented by Vitalik Buterin, and he invested deeply in Ethereum–both financially and by helping to establish the early Ethereum community. Anthony started Decentral in 2014, which is a hub for his projects in

A financial exchange is an operationally intensive business. You have customers making a high volume of transactions, your service has to be low latency and highly available, and you are dealing with a lot of money. A cryptocurrency exchange has all of the complexity of a typical financial exchange–and then some additional complexity. ShapeShift is

Cryptocurrency speculation has pulled in a large population of people who do not know what they are investing in. If you hear about an investment of $1000 turning into $1M, it’s tempting to get sucked in yourself. For most of these everyday people, the game is completely rigged. A large percentage of market activity is

In the finance industry, many people have a computer on their desk called a Bloomberg terminal. A Bloomberg terminal contains news, stock prices, communication tools, and other features that make it worth a high subscription price. And people in finance can afford to pay that high subscription because their decisions can cause a gain or

Most applications today run on a cloud provider like AWS. They are built with a framework like Ruby on Rails. They use a set of APIs like Stripe and Twilio for middleware services. This is the era of “web 2.0.” With decentralized systems, we are starting to get a feel for what “web 3.0” might

Decentralized applications can be built on the Ethereum blockchain. Just as the Bitcoin blockchain is a distributed, append-only ledger of financial transaction history, Ethereum is a distributed, append-only ledger of computational transaction history. New kinds of applications can be built on the Ethereum blockchain—and just like every new technology, we need an interface to bridge

Decentralized applications might someday offer alternatives to modern monopolies. Uber, Airbnb, Facebook, Amazon—all of these services could be recreated on a decentralized stack of technologies like Ethereum, IPFS, and Golem. Fully decentralized services could be more transparent, cheaper, and more efficient. But let’s be realistic. Today, even the simplest applications of fully decentralized blockchains don’t

For a decade, Bitcoin’s proof-of-work system has run without disruption. In a proof-of-work scheme, Bitcoin miners compete to solve a cryptographic puzzle associated with a block of transactions. Every ten minutes, all the Bitcoin miner nodes race to be the first to solve a block of transactions. Only one miner wins each block, meaning the

Humans organize into groups. There are lots of group types: religions, corporations, national governments, state governments, citizenries, clubs, musical bands. Every group has governance. Governance defines the rules and the ways that rules change. The United States requires citizens to pay taxes. A corporation requires you to show up to work, but they have to

Smart contracts are programs that run on the Ethereum blockchain. A smart contract developer pays Ether to deploy the contract. When a contract is deployed, every full node on the Ethereum blockchain has a copy of the contract code in that node’s address space. Every full node needs to hold a copy of every smart
