A cryptocurrency wallet stores the public and private “keys” or “addresses” which can be used to receive or spend the cryptocurrency. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.

Srinivasan and Ravikant warn that some uses of cryptocurrency tokens, including some ICOs, may be subject to regulation by governments if they are seen as equivalent to doing a traditional equity offering or IPO, in which investors receive shares of the company. But they argue other uses of tokens for crowdfunding could essentially be unregulated.

When a piece of work is created or performed, the digital rights to that piece are oftentimes complex and spread across many different organizations and entities. This makes it difficult for artists to get paid for their work and many large platforms, like Spotify, suffer from lawsuits because they do a good enough job of navigating the labyrinth. How might you build a system to help artists get paid for their work? In partnership with the Berklee College of Music, Harvard Berkman Center, and several industry partners in the Open Music Initiative, we are investigating the design of a blockchain-inspired open and interoperable digital rights management platform.
Ripple — Unlike most cryptocurrencies, it doesn’t use a Blockchain in order to reach a network-wide consensus for transactions. Instead, an iterative consensus process is implemented, which makes it faster than Bitcoin but also makes it vulnerable to hacker attacks.

ביטקוין מאחסן את כל ההיסטוריה של עסקאות שהתרחשו אי פעם, הנקראות שרשרת רצופה של בלוקים או בלוקציין. שרשרת הבלוקים יודעת הכול. לכן, אם יש לך כתובת ביטקוין בשימוש ציבורי, אז כל אחד יכול לראות כמה ביטקוינים יש לך על החשבון. מצד שני אם אתה לא אומר שזו הכתובת שלך, אז אף אחד לא יידע אי פעם שזה שייך לך. עבור אנונימיות מלאה, כתובת אחת של ביטקוין משמש בדרך כלל עבור עסקה אחת.

The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme. In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid. IOTA was the first cryptocurrency not based on a blockchain, and instead uses the Tangle. Built on a custom blockchain, The Divi Project allows for easy exchange between currencies from within the wallet and the ability to use personal identifying information for transactions. Many other cryptocurrencies have been created though few have been successful, as they have brought little in the way of technical innovation. On 6 August 2014, the UK announced its Treasury had been commissioned to do a study of cryptocurrencies, and what role, if any, they can play in the UK economy. The study was also to report on whether regulation should be considered.
