Blockchain is often described as unhackable, a reputation that has attracted billions in investment and reshaped how we think about digital trust. But that framing is misleading. Blockchain is not unbreakable; it is, more precisely, extraordinarily difficult to attack when built and used correctly. Four interlocking pillars give blockchain its security: cryptographic hashing, block chaining, decentralization, and consensus mechanisms. Understanding how these pillars work together is essential for anyone moving real value on a blockchain network, whether you are an individual investor or a business integrating distributed ledger technology into operations.
Key Takeaways

Details
Layered security pillars
Blockchains are secured by cryptographic hashing, record chaining, decentralization, and consensus mechanisms working together.
Immutability of records
Any attempt to change past blockchain data is virtually impossible thanks to hash links and distributed copies.
