Paper of the Week

Paper Title: Balance : Dynamic Adjustment of Cryptocurrency Deposits.

TLDR: 

  1. Aims to resolve the dilemma of balancing deposits in cryptoeconomic protocols with event dependency and private information.

  2. Provides dynamic adjustment of deposits in over-collateralized protocols, improving agents’ financial welfare, without compromising security.

  3. The mechanism may be used as extension to an existing cryptoeconomic protocols to control the amount of deposit an agent has to provide to resolve the dilemma of having “too high” or “too low” deposits.

  4. Suitable examples for integrating Balance include FairSwap, TrueBit, and XCLAIM.

  5. Agents that aim to misbehave in a protocol obtain more utility if they do early on, before any reductions in their deposit occurs.

  6. Conversely, honest and rational agents receive a higher utility byconsistently acting in the interest of the protocol.

  7. Agents are tracked by a decentralised registry that stores a ranking of their contributions towards the protocol.

  8. The mechanism maps agents to layers according to their behaviour where, if the agent’s score is high enough by the end of a round, it moves to the next layer.
