The quiet rewrite of the internet's handshake
Browsers and servers are already swapping the cryptography that protects every connection — years before the machine that would break it exists. The cost isn't speed, it's bytes.

Blockchain Simplified
Breaking down the complex world of distributed ledgers into digestible concepts — from hashing to consensus mechanisms.
SamScience and technology writerUnderstanding Blockchain Technology
Blockchain technology is a distributed ledger shared across many nodes. What makes it special is that once information is added, it becomes difficult to change or delete without consensus.
Core Concepts
- Blocks: Containers of transactions
- Chain: Each block links to the previous via a cryptographic hash
- Consensus: Network rules that determine truth
Use Cases
Cryptocurrencies, supply-chain tracking, verifiable credentials, and more.
Limitations
Throughput, energy usage (for some consensus algorithms), and usability are still active areas of improvement.
