xpub(extended public key)
: 나의 니모닉에 귀속된 모든 주소를 생성할 수 있음
→ 모든 지갑 데이터, 거래 내역(트랜잭션)을 볼 수 있음(watching-only wallet)
→ 니모닉/개인키 없이 비트코인을 옮길 수는 없지만, 익명성/보안을 중대하게 해치기 때문에 비공개로 유지하며 ‘절대 공유 금지’
A xpub, stands for "extended public key".
→ The key that generates all your addresses, thus one can get all your wallet data and transactions.
→ This key should remain private and never be shared.
