"On chain contracting" is of course a very generic term; it applies to multisignature, coinjoin, coinswap or other exotic transactions that involve more than one party in one transaction (coinjoin, multisig) or multiple transactions (swaps with atomic-via-secret).
Here we're going to focus on a broader model that may allow more complex setups,
| This document is an attempt to define metrics quantifying the degree of privacy provided by a bitcoin transaction. | |
| Objectives | |
| Definition of metrics measuring the resistance of a transaction to a set of attacks against users privacy. | |
| Attacks considered in the scope of these metrics are: | |
| - Merged Inputs Heuristic: methods identifying the inputs controlled by a same entity | |
| - Coinjoin Sudoku: methods identifying the links existing between the inputs and outputs of a transaction |
| Context | |
| In part 1 of this document, we've defined the entropy of a transaction. | |
| This metric is a first good proxy to qualify the degree of privacy provided by a transaction but it fails to detect privacy leaks occuring at lower levels (1). | |
| In this second part, we define 2 complementary fine-grained tools/metrics: the Link Probability of 2 utxos (LP) and the Link Probability Matrix (LPM) of a transaction. | |
| Link Probability of 2 UTXOs | |
| We call Link Probability of a tuple (tx input, tx output) the probability that a link exists between the 2 utxos. |
| Context | |
| This third part is about known and potential attacks against the privacy provided by tools like coinjoin. | |
| Known attacks & weaknesses | |
| - Linkability of inputs and outputs | |
| A good illustration of this attack is Coinjoin Sudoku (see (1) for details). |
