Master blockchain architecture and build decentralized applications. Learn consensus mechanisms, scalability solutions, and real-world dApp development.
How blockchains work
A blockchain is a distributed ledger that records transactions across many computers. Understanding its architecture is fundamental to blockchain development.
Blocks
Container of transactions with timestamp, hash, and previous hash
Chain
Linked blocks creating immutable history via cryptographic hashes
Nodes
Computers that validate, store, and distribute blockchain data
Consensus
Agreement mechanism for adding new blocks (PoW, PoS, etc.)
Agreeing on truth
Tracking blockchain data
Making blockchains faster
Building on blockchain
Decentralized applications
