Coordifier - A watchtower plugin for your node that continuously audits coordinators for honesty, stability, and liquidity

[Kruwed]

-No coins that don't exist [Pass/Fail]
-No invisible rounds [Pass/Fail]
-No duplicate rounds [Partially deniable]
-No spent coins [Partially deniable]
-Fidelity bonds [Extra reputation]

Stability:

-Success rate [Input registration attempts | Signing attempts]
-Time in mempool [Target 10 mins]
-Number of inputs dropped during registration [Completely deniable]
-Value of inputs dropped between rounds [Completely deniable]

Liquidity:

-Round size [Numeric scale]
-Round value [Numeric scale]
-Input anon score [Numeric scale]
-Output anon score [Numeric scale]
-Remixed inputs [Numeric scale]
-Remixed inputs [% value]
-Whale change outputs [% value]
-Payment outputs [% value]

Cost:

-Total mining fees paid [Cost of Sybil attacker]
-Bitcoin days destroyed [Liquidity of Sybil attacker]
-Overcharged mining fees [Wasteful coordinator]
-Discarded dust [Contributions from altruistic coordinators]
-Claimed dust [Coordinator's opportunity cost]
