To its users, traders, and holders (or hodlers!), Bitcoin is a type of electronic money that, unlike almost every previous alternative, exists independently and outside the control of any state or financial institution. It doesn’t recognize any borders, meaning that it can be transferred between participants on its network without the need for or i...
Bitcoin uses cryptography to verify transactions and record them on a blockchain, which is a public distributed ledger. A ledger isn’t a revolutionary concept, but it is required as a record of transactions within a financial system. The fact that the ledger used by BTC is publicly distributed marks a significant departure from the traditional fina...
Bitcoin’s protocol limits its supply, effectively creating a predefined monetary policy, and sets this limit at a total of 21,000,000 BTC. This is an amount that is yet to be reached, because Bitcoins are still being created as a reward for miners. The original reward of 50 BTC per mined block as of the genesis block has been halved several times t...
Bitcoin is the easiest cryptocurrency to purchase. Ever since the pizza delivery guy who effectively bought 10,000 BTC for the price of two pizzas, Bitcoin has been an effective peer-to-peer currency - and it can still be purchased in a peer-to-peer fashion. Every exchange of note, centralized or decentralized, will also offer BTC. You can not only...
As mentioned above, you need a wallet to store Bitcoin. This is not strictly true, however, being that Bitcoins are stored on the blockchain and wallet addresses only identify them. But, to all intents and purposes, having a wallet and keeping its private key safe is similar to being in possession of and not losing a physical wallet containing cash...
Bitcoin is based on extremely safe SHA-256 cryptography created by the National Security Agency of the U.S., and the bitcoin protocol includes many features protecting it against various vectors of attack, including: 1. Double Spending. This type of attack involves the user trying to send the same Bitcoin to two different addresses in succession. I...
As awareness about Energy Consumption and the need to be Green has swept over consumers, critics of Bitcoin have used its consumption of energy as a vector of attack. Reports have claimed Bitcoin’s transactions take ‘as much electricity as an American household does in six weeks’, and that Bitcoin’s annual energy requirement amounts to more than th...
Bitcoin halving refers to the reduction of the Bitcoin block reward paid out to miners upon the successful creation of a new block. As set out in the Bitcoin Protocol, this reward began at 50 BTC with the genesis block in January 2009. It has since halved every 210,000 blocks to 25, 12.5 and most recently to 6.25 BTC. These halvings and the predefi...
The fixed monetary value and software-defined scarcity of Bitcoin are commonly used as arguments why Bitcoin is a valuable investment. With a fixed maximum supply of 21 million BTC and a slowing supply toward that number as halvings take place, its value is evident as the network effect takes hold when compared to fiat currencies that have no suppl...
Developers upgrade Bitcoin by conducting a fork in the network. These forks are essentially changes in the protocol of the Bitcoin network and can be implemented for several reasons. The most common reason to fork Bitcoin is to upgrade it, and a fork causes a split in the transaction chain. This creates a development structure and an opportunity to...
