What Is Address?
A blockchain address is a unique alphanumeric string that serves as a destination for sending and receiving cryptocurrency. Think of it like a bank account number — it identifies where funds should go. Bitcoin addresses start with 1, 3, or bc1; Ethereum addresses start with 0x. Each address is derived from a public key using cryptographic hash functions.
How Address Works
Addresses are generated from public-private key pairs. The private key (which must remain secret) generates the public key, which generates the address. Anyone can send funds to an address, but only the private key holder can spend from it. Modern wallets generate new addresses for each transaction to improve privacy, though all addresses in a wallet are controlled by the same seed phrase.
Why It Matters for Traders
Understanding addresses is fundamental for on-chain analysis. Clustering algorithms group addresses belonging to the same entity, enabling whale tracking and exchange flow analysis. Address activity patterns (frequency, transaction sizes, counterparties) reveal trader behavior. On-chain analysts can identify institutional accumulation, exchange deposits/withdrawals, and DeFi positions by monitoring specific addresses.
