Solving the 0-conf problem using forfeits

by /u/awemany

Overview

The problem of ensuring good security for unconfirmed transactions in Bitcoin is repeatedly discussed in the community. Right now these so-called 0-conf transactions are usually expected to be of low risk in the case of small amounts and face-to-face interaction of merchant and customer.

0-Confirmation Double-Spend Protocol

The problem

Bitcoin-accepting merchants want to receive payment and provide services instantly. However, block construction times can be as much as 10 minutes after the moment a bitcoin transaction is broadcast. In the time after a transaction but before a block’s creation, that transaction can be superseded by another transaction with a larger fee paid to miners.

With the change in the mempool protocol from first-seen-first-included and the rejection of conflicting double spends, to the inclusion of double spends and prioritizing transactions with larger fees attached, 0-conf transactions can no longer be reasonably secure for any sized transaction.

The idea of replace-by-fee was that miners will follow their immediate self-interest, and if miners sporadically act that way, could potentially decrease trust in the system. Now that this approach has been assumed and is the default behavior of miner software, we might consider amending t

# The Witness Algorithm: Privacy Protection in a Fully Transparent System
By **Vlad Gluhovsky** and **Gavin Wood**

# Introduction

Being based upon a quasi-Turing-complete (quasi because it's actually bounded) virtual machine, Ethereum is an extremely versatile system. However one of its greatest strengths---universal auditability---seems to lead to a fatal flaw, namely an inescapable lack of privacy. Here we demonstrate an algorithm in order to prove that this is not the case.

The algorithm could be used to make an Ethereum contract which, given two sets of addresses sources, `src`, and destinations, `dest`, will guarantee exactly one of two possible eventualities:

- For each address in `src`, the controller of that address controls a corresponding address in `dest` (though the two cannot be related *a priori*).
