Your guide to Crypto and Blockchain technology — A ChainEX article
Ever wondered how exactly the blockchain works, what it is, and what it does? It recently dawned on me just how many people invest in and trade digital assets in South Africa and abroad, but don’t really know what goes on behind the scenes. No worries, we’ll break it down for you ?
What is Blockchain?
A Blockchain is a type of diary or spreadsheet containing information about your transactions. Each transaction generates a hash. Each block refers to the previous block and together make the Blockchain. A Blockchain is effective as it’s spread over many computers, each of which has a copy of the Blockchain ?
Okay, in plain English. Well, technically speaking a Blockchain is a diary that is almost impossible to forge. The first major application of blockchain technology was Bitcoin which was released in 2009. Bitcoin is a cryptocurrency and the blockchain is the technology that underpins it. A cryptocurrency refers to a digital coin that runs on a blockchain. But you know this because you read our previous article on it. ?
The role of Blockchain in Crypto
Okay, so essentially the blockchain behind Bitcoin is a public ledger of every transaction that has taken place. It can’t be tampered with or changed. Advocates of the technology say this makes Bitcoin transactions secure and safer than current systems.
A few fun facts about Bitcoin ?
- It’s not issued by a central authority.
- There is a limit of 21 million.
- The first transaction using Bitcoin is widely believed to be carried out by a programmer named Laszlo Hanyecz, who spent 10,000 Bitcoin on two Papa John’s pizzas in 2010. Yep.Ho Pizzas.
- The identity of Bitcoin creator Satoshi Nakamoto remains a mystery.
- Bitcoin is one of the digital assets available to trade or buy on ChainEX
How Bitcoin works
The Bitcoin blockchain is “decentralized,” meaning it is not controlled by one central authority.
While traditional currencies are issued by central banks, Bitcoin has no central authority. Instead, the bitcoin blockchain is maintained by a network of people known as miners. For more information, read our Bitcoin Guide article ?
You’ve probably read the term “Node” a lot on our Telegram group. Well, these “miners,” sometimes called “nodes” on the network, are people running purpose-built computers that are actually competing to solve complex mathematical problems in order to make a transaction go through.
Is the Blockchain really secure?
More than you can imagine ? One of the advantages of blockchain is that it can’t be tampered with. Each block that is added onto the chain carries a hard, cryptographic reference to the previous block.
Because the blockchain is not centralized, it also means that if one part of it went down, the whole network would not collapse. There are many different parts of the Bitcoin network that require it to work. So even if one miner went out of action, for example, transactions would still work. ?
