Can they do it? Or they "talk" to a full node for that purpose and are used only for mining purposes?

Thanks in advance for your answers.

  • See BIP37: https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki SPV nodes receive transactions from full nodes that match a filter pattern. – pinhead Aug 23 '19 at 06:04
  • And how do they calculate balances? I read what you posted and I can't understand a word. – evannemo Aug 23 '19 at 12:12
