An Abstract Model of UTxO-based Cryptocurrencies with Scripts

Joachim Zahnentferner

Abstract

In [1], an abstract accounting model for UTXO-based cryptocurrencies has been presented. However, that model considered only the simplest kind of transaction (known in Bitcoin as pay-to-pubkey-hash) and also abstracted away all aspects related to authorization. This paper extends that model to the general case where the transaction contains validator (a.k.a. scriptPubKey) scripts and redeemer (a.k.a. scriptSig) scripts, which together determine whether the transac- tion’s fund transfers have been authorized.
