How a Blockchain Transaction Works
A simplified educational overview
This is a simplified educational overview. Real blockchain implementations vary by network.
Crypto Myths
Common misconceptions — explained clearly.
"Crypto transactions are completely anonymous."
Most cryptocurrency transactions are pseudonymous, not anonymous. All transactions are recorded permanently on a public blockchain, visible to anyone. With the right tools, transactions can often be traced back to real identities.
"Bitcoin and blockchain are the same thing."
Blockchain is the underlying technology — a distributed, tamper-resistant ledger. Bitcoin is one application built on blockchain technology. Many other blockchains and cryptocurrencies exist independently.
"Your cryptocurrency is stored inside your wallet."
Your coins live on the blockchain — not inside any device or app. A wallet stores the private keys that prove ownership and authorize transactions. The blockchain maintains the actual record of balances.
"All cryptocurrencies work the same way."
Different cryptocurrencies use radically different consensus mechanisms, architectures, supply models, and purposes. Bitcoin uses Proof of Work. Ethereum uses Proof of Stake. Solana uses Proof of History. Their designs, trade-offs, and goals differ significantly.
"Crypto transactions can always be reversed."
Most blockchain transactions are irreversible. Once a transaction is confirmed on the blockchain, it generally cannot be undone. This is by design — immutability is a core feature of blockchain security.
