Blockchain technology may sound complex, but at its core, it’s quite straightforward. Simply put, a blockchain is a public database that stores a history of transactions. Unlike a regular database, a blockchain is decentralized and immutable, making it a secure and transparent option for various applications.
What is Blockchain?
In regular human language, a blockchain can be described as a digital ledger that records transactions between parties. Here are the main differences between a regular database and a blockchain:
-
Append-only: Once data is added to a blockchain, it cannot be changed or altered. This immutability ensures the integrity of the information stored on the blockchain.
-
Linked-list structure: A blockchain is a linked-list of blocks, with each block containing a set of transactions. Each block points to the previous one, creating a linear history of transactions.
-
Decentralized: Unlike traditional databases owned by specific organizations, blockchains are distributed among many users who run nodes. These nodes contain identical copies of the entire blockchain history. By constantly communicating and agreeing on the state of the blockchain, it becomes challenging to manipulate the data. Hacking a blockchain would require a 51% attack, where the majority of nodes agree on a new blockchain state.
What are cryptocurrencies?
Cryptocurrencies are digital currencies that can be exchanged online as a form of payment for goods and services. They are one of the primary forms of data stored on a blockchain. Here are some key characteristics of cryptocurrencies:
-
Permissionless: Unlike traditional financial platforms, anyone in the world can access and transfer cryptocurrencies without the need for registration. This ensures that users have control over their assets without the involvement of third parties.
-
Anonymity: Cryptocurrencies allow for the transfer of ownership without requiring proof of identity. Unlike financial platforms regulated by governments, cryptocurrencies offer a level of privacy and anonymity.
-
Volatility: Cryptocurrencies are known for their price volatility, which can be influenced by various factors such as market expectations and the overall state of blockchain technology. Stablecoins are an exception to this volatility.
