- How does blockchain work?
At its core, blockchain is a decentralized, digital ledger that records transactions in a secure, transparent and tamper-proof way. Instead of storing data in a central location, where it's more susceptible to hacking or manipulation, blockchain technology distributes and stores data across a network of computers, making it virtually impossible to tamper with or hack.
Each block in the chain contains a unique code, or hash, that's used to identify it, as well as the hash of the previous block in the chain. This creates a chain of blocks that can't be altered without changing every block that comes after it. Once a block is added to the chain, it's considered permanent and can't be altered or deleted.
To add a new block to the chain, a network of computers must first verify the transaction. This is done through a process known as consensus, which ensures that all the computers in the network agree on the validity of the transaction. Once consensus is reached, the transaction is added to the block and the block is added to the chain.
Because blockchain technology is decentralized, there's no need for a central authority to oversee transactions. Instead, transactions are verified and processed by the computers in the network, making it faster, more efficient, and more secure than traditional systems. This has huge implications for a wide range of industries, from finance and healthcare to supply chain management and beyond.
- Why blockchain is secure
Blockchain technology is known for its high level of security, which is why it is quickly gaining popularity across various industries. Unlike traditional systems, where data is stored in a central location, blockchain data is decentralized and distributed across a network of computers. This means that there is no single point of failure, making it difficult for hackers to attack the system.
Another security feature of blockchain is that it uses cryptography to secure data. Each block in the chain is encrypted with a unique code, and each block links to the previous block using this code, creating an unalterable chain of information. Transactions made on the blockchain are verified and approved by a network of users, which makes it impossible for any single user to manipulate the data.
Moreover, blockchain technology is transparent, meaning that all users on the network can view the records stored on it. This creates a system of accountability that discourages fraudulent activity, as it is easily detectable by the network.
Overall, the security features of blockchain technology make it an ideal solution for industries that require high levels of data security and transparency, such as finance, healthcare, and government.
