@ -1000,3 +1000,15 @@ The new algorithm allows the number of
hash operations increases by a much more gradual O(n) to the number of
signature operations, reducing the opportunity to create
denial-of-service attacks with overly complex transactions.
In this chapter, we learned about schnorr and ECDSA signatures for
Bitcoin. This explains how full nodes authenticate transactions to
ensure that only someone controlling the key to which bitcoins were
received can spend those bitcoins. We also examined several advanced
applications of signatures, such as scriptless multisignatures and
scriptless threshold signatures that can be used to improve the
efficiency and privacy of Bitcoin. In the past few chapters, we've
learned how to create transactions, how to secure them with
authorization and authentication, and how to sign them. We will next
learn how to encourage miners to confirm them by adding fees to the
transactions we create.
