What is Blockchain?
Blockchain is a distributed digital ledger technology that records transactions in an immutable and secure way. It is decentralized, meaning no single entity controls the network. Instead, thousands of computers around the world verify and approve transactions on the blockchain.
The data is stored on the network in “blocks” that contain details like transaction time and dollar amount. Each new block is linked to previous blocks, creating an unbroken chain of data referred to as a “blockchain.” This structure is extremely difficult to alter, providing security and transparency.
How Does Blockchain Work?
Blockchain networks consist of three main components: a peer-to-peer network, consensus mechanism, and cryptography. The peer-to-peer network allows participants to share and receive data without a central authority. To add new transactions, a majority of nodes must agree that the transactions are valid – this agreement is called reaching consensus.
Cryptography secures the network by converting transaction data into complex code called a “hash.” Any changes to the data produce a new hash, signalling potential tampering or errors.
Key Benefits of Blockchain Technology
- Decentralization – No single authority controls the network
- Transparency – All participants can view transaction details
- Security – Data is difficult to alter due to cryptographic hashes
- Immutability – Transactions cannot be changed, only new ones added
- Efficiency – Peer-to-peer structure removes third party intermediaries
Blockchain Use Cases
Blockchain technology is being applied across a diverse range of industries to enhance transparency, efficiency, and security. Here are some of the key sectors using blockchain and examples of how it is transforming operations:
Finance
Blockchain enables digital currencies like Bitcoin that allow peer-to-peer electronic transactions without a central bank or authority. It also powers cross-border payment platforms like Ripple that provide faster settlement times and lower costs compared to traditional banking.
Supply Chain
Blockchain brings transparency and traceability to supply chain operations. It tracks goods from production through delivery, capturing key data like location and certifications. Platforms like TradeLens are emerging to digitize supply chain paperwork and processes.
Healthcare
Blockchain securely stores patient medical records and allows permissioned sharing between providers. This maintains privacy while enabling access to vital health data efficiently.
Real Estate
Blockchain provides immutable records of property titles and transactions. It aims to significantly reduce the time needed for processing deeds and ownership transfers.
Voting
Blockchain enables secure digital ballot casting and vote tallying for elections and referendums. It prevents tampering with results and allows accurate, transparent vote counts. Switzerland is experimenting with blockchain voting.
