Bitcoin (BTC)


What is Bitcoin?

Bitcoin is a decentralised digital currency, meaning it does not belong to any government, nor is it regulated by any institution. In recent years, Bitcoin has become increasingly popular and been coined “digital gold”, because it shares similar properties; scarcity, portability, durability, divisibility, and difficulty to counterfeit. Bitcoin can also be used as an investment vehicle with a limited supply. It increased in value from less than US$1 per bitcoin to over US$6,000 per bitcoin throughout 2017.


In Bitcoin, a block is a group of transactions from a particular time frame. Each new block depends on the preceding ones as they are stacked on top of each other. Thus, a chain of blocks is created, giving the term "blockchain" its meaning.

The previous blocks become immutable each time a new block is introduced. This guarantees each block becomes more secure over time, and also illustrates how Bitcoin technology alters the way money is exchanged in the banking and financial sectors.


To achieve network consensus, the Bitcoin protocol uses a Proof-of-Work (PoW) method based on the SHA-256d algorithm. The network's target block time is 10 minutes, and there are 21 million tokens available at a token emission rate declining. An algorithm updates the network's block difficulty based on the previous 2016 block times to prevent fluctuations in the block time.

The Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, have both been supported by the Bitcoin Protocol as solutions to network scalability, because the block size limit is restricted at 1 megabyte.

What makes Bitcoin unique?

Bitcoin is the world's first and largest decentralised cryptocurrency in terms of market capitalisation, and ensures all transactions are accurate. The blockchain keeps a record of every action, and nothing is missed from the network. Any user in the system has access to the complete record after an activity is time-stamped, logged, and saved in one of the information blocks.

Who is behind Bitcoin?

The Bitcoin whitepaper was published anonymously in 2008 by a pseudonymous person or team named Satoshi Nakamoto. Bitcoin is an open-source project with global development communities and more than 600 contributors on GitHub, as of the time of writing.
