O que é Address?
A string encoding the conditions under which an output can be spent. Bitcoin's equivalent of an account number, except you can make unlimited ones.
Modern addresses begin with bc1 (native SegWit or Taproot); older formats begin with 1 or 3. Native SegWit addresses cost less to spend from.
Reusing an address links all payments to it publicly, so wallets generate a fresh one per receipt. Always verify an address on the signing device itself, not only on a screen malware could alter.
An address is not an account and not a person. One user can hold thousands; one exchange can serve millions from a few.
