Aragon is a decentralized app (dApp) on the Ethereum blockchain that allows anyone to create and manage a decentralized organization. The Aragon project is open source and led by the Aragon Foundation. It also includes a token, ANT, that grants voting rights to make decisions about the direction of future development. Eventually, Aragon hopes to be a fully decentralized autonomous organization and dApp that’s a neutral jurisdiction for anyone to create an organization on the blockchain. In the early days of development, the project is relying on the nonprofit Aragon Foundation to provide direction and support as the project gets off the ground. The idea, however, is to eventually dissolve, scale back, or change the nature of the Foundation as community support grows. In the future, Aragon will be entirely decentralized and community led. Holders of the ANT token will have voting rights on all issues concerning Aragon. Aragon is an open source, non-profit project. It has many contributors. It also doesn’t technically have a CEO or CTO. Instead, it has a project lead. But don’t get it twisted, the lead is essentially the CEO. uis Cuende is leading the project. In 2011, he received a “Best Underage European Programmer” award, and he’s a recipient of Forbes’ 30 under 30 recognition. He’s a young guy, but with leadership and technical chops. He has advised the Vice President of the European Commission and is an MIT Innovators Under 35 awardee. He has founded several startups and created the first Linux distribution with face login. Aragon offers several core features. It has a module for identity management and closely related modules for ownership and access control. Other modules include shareholder voting, fundraising through token generation, HR onboarding and payroll, and accounts payable/receivable. Taken together, the core functionality of Aragon covers the critical aspects of accounting, governance, and identity that make modern companies work. As you can see, these modules make up most of the administrative functions that a modern company or organization requires. It’s important to emphasize that these modules can individually be turned on and off, providing instant customization for the company’s needs. In addition, all of the code behind Aragon is open source. A company’s development team could edit them as needed to fulfill the company’s requirements. The modular design of Aragon doesn’t stop with the core modules that come standard. Just as companies can edit existing modules, they’re free to develop completely new models as well. They can also develop atop the data and structures of existing models for extended functionality. The modular nature of Aragon, combined with its open source ethos, means we could see a whole ecosystem of free to use modules that extend capacity for organizations on Aragon. Aragon explicitly has the goal of creating a digital jurisdiction. Just like countries have jurisdiction over their citizens when it comes to courts of law, Aragon wants to create the first digital court of law. This court wouldn’t operate based on country boundaries. Instead, it would help enforce digital contracts between organizations on the Aragon platform. The ANT token is the native token of Aragon and plays a critical role in the governance model and incentive structure of the platform. It represents the wealth of the decentralized economy and was initially sold during Aragon’s highly successful ICO in May 2017 that raised $24 million. Subsequently, the ANT token has come to represent a powerful share of the governance on the platform. ANT holders can vote on proposals, participate in arbitration and the decentralized court system, and help contribute to the non-profit Aragon Foundation or to research and development through the Aragon Nest program.
The bitcoin network is a peer-to-peer payment network that operates on a cryptographic protocol. Users send and receive bitcoins, the units of currency, by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software. Transactions are recorded into a distributed, replicated public database known as the blockchain, with consensus achieved by a proof-of-work system called mining. Satoshi Nakamoto, the designer of bitcoin claimed that design and coding of bitcoin began in 2007. The project was released in 2009 as open source software. The network requires the minimal structure to share transactions. An ad hoc decentralized network of volunteers is sufficient. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will. Upon reconnection, a node downloads and verifies new blocks from other nodes to complete its local copy of the blockchain. A bitcoin is defined by a sequence of digitally signed transactions that began with the bitcoin's creation, as a block reward. The owner of a bitcoin transfers it by digitally signing it over to the next owner using a bitcoin transaction, much like endorsing a traditional bank check. A payee can examine each previous transaction to verify the chain of ownership. Unlike traditional check endorsements, bitcoin transactions are irreversible, which eliminates the risk of chargeback fraud. Although it is possible to handle bitcoins individually, it would be unwieldy to require a separate transaction for every bitcoin in a transaction. Transactions are therefore allowed to contain multiple inputs and outputs, allowing bitcoins to be split and combined. Common transactions will have either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and one or two outputs: one for the payment, and one returning the change, if any, to the sender. Any difference between the total input and output amounts of a transaction goes to miners as a transaction fee. In 2013, Mark Gimein estimated electricity consumption to be about 40.9 megawatts (982 megawatt-hours a day). In 2014, Hass McCook estimated 80.7 megawatts (80,666 kW). As of 2015, The Economist estimated that even if all miners used modern facilities, the combined electricity consumption would be 166.7 megawatts (1.46 terawatt-hours per year). To lower the costs, bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free. Chinese bitcoin miners are known to use hydroelectric power in Tibet to reduce electricity costs. Various potential attacks on the bitcoin network and its use as a payment system, real or theoretical, have been considered. The bitcoin protocol includes several features that protect it against some of those attacks, such as unauthorized spending, double spending, forging bitcoins, and tampering with the blockchain. Other attacks, such as theft of private keys, require due care by users.
