A “cryptocurrency” is a peer-to-peer, decentralized, digital currency. Cryptocurrencies offer the potential for merchants to one day break the stranglehold of credit card processing fees. Cryptocurrencies are a disruptive technology that should be actively followed and considered. After all, online commerce is itself a disruptive technology.
Bitcoin
Bitcoin’s high cryptographic security allows it to process transactions in a very efficient and inexpensive way. You can make and receive payments using the Bitcoin network with little or no fees, and without a merchant account. Payments are made from a wallet application, either on your computer or smartphone, by entering the recipient’s address, the payment amount, and pressing send. To make it easier to enter a recipient’s address, many wallets can obtain the address by scanning a QR code or touching two phones together with NFC technology. Market Cap: $10.6 billion (12.1 million coins).
Bitcoin is the first implementation of a cryptocurrency, which was first described in 1998 by Wei Dai and specified by Satoshi Nakamoto in 2009, establishing a decentralized form of money that uses cryptography to control its creation and transactions. New Bitcoins are generated by a competitive and decentralized process called “mining,” the process of spending computing power to process transactions, secure the network, and keep everyone in the system synchronized together. The number of new Bitcoins created each year is automatically halved over time until Bitcoin issuance halts completely with a total of 21 million Bitcoins in existence.
Feathercoin – is based on Litecoin’s Scrypt-based hashing algorithm for GPU mining, rather than requiring Bitcoin’s expensive ASIC mining hardware. Feathercoin uses advanced checkpointing to provide additional security through a form of centralization without having to redistribute the Feathercoin software. At mining completion, 336 million coins will be produced. Market Cap: $11 million (26.2 million coins).
Litecoin – is based on the Bitcoin protocol, but differs from Bitcoin in that it can be efficiently mined with consumer-grade hardware. Litecoin provides faster transaction confirmations and uses a mining proof-of-work algorithm to target the regular computers with GPUs — graphics processing unite — most people already have. Litecoin provides a mining algorithm that can run at the same time on the same hardware used to mine Bitcoins. The Litecoin network is scheduled to produce 84 million currency units. Market Cap: $731 million (23.9 million coins).
Megacoin – raises the most red flags among this list of cryptocurrencies. Launched just six months ago, fifty percent of the total coins have been mined. Upon mining completion, only 42 million coins will exist. Its branding might lead an investor to believe it is associated with billionaire Kim Dotcom’s Mega.co.nz, but there is no connection. If you are interested in monitoring the fate of the more speculative cryptocurrencies, this is one to watch. Market Cap: $15.3 million (21.2 million coins).
Namecoin – is based on the Bitcoin source code. A cryptocurrency, Namecoin also acts as a DNS, a decentralize domain name system to buy, register, configure, and sell domains. The first project using Namecoin is the .bit domain. Market Cap: $44.4 million (7.4 million coins).
Peercoin – is a cryptocurrency project forked from Bitcoin that strives to achieve energy efficiency and increased security. Like other cryptocurrencies, initial coins are mined through the more commonly used proof-of-work hashing process. However, unlike other coins, as the hashing difficulty increases over time, users continue to be rewarded with coins generated by the additional proof-of-stake algorithm. Unlike most cryptocurrencies, Peercoin does not have a fixed money supply. Market Cap: $90.1 million (20.9 million coins).
Primecoin – is the first cryptocurrency with non-hashcash proof-of-work. Primecoin’s proof-of-work is based on searching for prime number chains, providing potential scientific value in addition to minting and security for the network. Similar to Bitcoin, Primecoin enables instant payments to anyone, anywhere in the world. It also uses peer-to-peer technology to operate with no central authority. Primecoin is also the name of the open source software that enables the use of this currency. Market Cap: $13.8 million (3.5 million coins).
ProtoShares – are used to mine Distribute Autonomous Corporation (DAC) backed cyrptocurrencies while they are still in development by Invictus Innovations. DACs are essentially automated businesses that perform services. And so ProtoShares are stakes in future cryptocurrency platforms. Cryptocurrencies under development are BitShares for asset trading and DomainShares for domain services. Protoshares will achieve a maximum supply of approximately 2 million coins in 2 years. BitShares money supply will be about 20 million coins. Market Cap: $23.1 million (1.1 million coins).
Quark – is a cryptocurrency that focuses on enhanced security, using nine separate rounds of encryption and six different algorithms. Quark is mined by CPU only, with 247 million mined in the first six month and then an additional 1 million units mined every year. Quark coin will continue to release coins in perpetuity at an inflation rate of .5% per year. Market Cap: $47.4 million (246.3 million coins).
Worldcoin – seeks to become the cryptocurrency of choice for merchants and consumers for their everyday transactions. Transactions are fully confirmed in about 60 seconds. Due to frequent block generation (30 seconds), the network supports more transactions without a need to modify the software in the future. At mining completion, 265 million coins will be produced. Market Cap: $20.6 million (35.2 million coins).
