# New Methods for Transactions in Blockchain Systems

This work is the result of my master thesis in computer science from the University of Applied Sciences Western Switzerland.

## Abstract

Bitcoin is a decentralized peer-to-peer currency that allows users to to pay for

things electronically. Bitcoin was created by a pseudonymous software developer

going by the name of Satoshi Nakamoto in 2008, as an electronic payment system

based on mathematical proof. Yet the largest challenge in Bitcoin for the coming

years is scalability. Currently, Bitcoin can only handle a few transactions per

second on the network. This is not sufficient in comparison to large payment

infrastructures, which allow tens of thousands of transactions per second. As a

potential scalability solution, the idea of payment channels was suggested by

Satoshi in an email to Mike Hearn. A one-way payment channel specific for retail

commercial transactions is presented, analyzed and optimized with threshold

cryptography. The threshold scheme selected has been adapted and implemented

into the Bitcoin cryptographic library to compute a special two-party threshold

ECDSA signature.
