7 Cool Decentralized Apps Being Built on Ethereum Imagine a company or service that isn't controlled by any single individual, board or other central entity. Known as a decentralized application, or 'dapp' for short, the concept has been one of the more novel ideas to emerge from the blockchain community. Armed with self-executing smart contracts, proponents of the technology have envisioned ways to replace everything that today requires a centralized leadership, from businesses and services to governments. untitled Ahead of tomorrow morning’s expected hard fork of the Ethereum network, the #2 cryptocurrency technology after Bitcoin itself is already attracting plenty of added attention this week. Coinbase CEO and co-founder Brian Armstrong sounded off on the looming hard fork with a tweet: Aside from Coinbase star power, Ethereum is likely to benefit from a positive news cycle as a major $50,000 coder competition or “hackathon” focused around the technology launched this morning.
South Africa's Banks Are Going DIY to Test Ethereum's Blockchain Members of six African banks reportedly met yesterday to discuss the next steps in their ongoing effort to connect aspects of the South African banking system via a private version of the ethereum blockchain, according to sources. Present at the event was CIO of Barclays Africa's corporate and investment banking division, Andrew Baker, who said that while the unnamed banks are still in the early phases of the "most pure collaborative process" he’s ever participated in, the effort has been propelled by a surprising technology – instant messaging. After some early internal work within Barclays subsidiary, Absa, including logging archived payments on a blockchain and writing simple ethereum-based smart contracts, Baker created a WhatsApp group and invited a few of his peers at competing banks.
