I am looking for independent trusted agents (members with a reputation) to offer escrow and/or arbitration services on-demand.

Right-now, I want to crowdfund some projects, and I need some trusted members to prevent me from screwing anyone as I have no reputation whatsoever. This prompts this quest, yet the goal is for such service to be available to anyone who may (yet hopefully won't) need arbitration.

Unless there actually is a dispute, no agent is involved. i.e. No work, no pay, nor any knowledge that anything happened.

If there is a dispute, any party can then contact the relevant agent(s) to enforce their contracts and gets paid according to each agent's rule.

The task involves:
Signing the release or returns of funds for a fee on demand, and/or
Making a decision or statement for arbitration purposes.

Such service is to be paid according to whatever schedule determined by the agent offering the service.

The decision making and enforcement may be separate. For example Alice may investigate and render a decision, and Bob can enforces whatever decision is made by Alice. While involving multiple agents, it can provide much more flexibility, such as allowing appeals or a broader -- expertise.

The weakness (which is simply a compromise) is the intervention of humans. The advantage is that it allows complex contracts while avoiding the implementation of smart contracts and the risks posed by any potential bugs or back-door.

The goal is that no one ever uses these services for the same reason nobody is producing invalid blocks.

It requires that proper contracts are written, agreed and signed by all participants, so that proof can be provided to agent(s) in case of arbitration.

As for the fees, scope (expertise) and rules, that is up to each agents.

Please makes your offer if you want to be such an agent, and/or share the names/usernames of whoever you trust.
