Since its inception, Polkadot has been proudly advertising its on-chain governance system, promoting itself as a good solution to the old problems we were facing, for example, in Ethereum governance. Gradually, we discovered problems. In October 2023, I started the Web4 Initiative to promote discussions of those problems. The community was enthusiastic but did not treat the problem as very serious. After all, things seemed to work… until recently, where we started to have hot debates on certain governance issues such as grifting, with regards to, for example, the marketing bounty, etc.
During the years, the Web4 initiative went on-and-off, but our study, from a game theoretic aspect for an on-chain plutocracy governance system (that Polkadot itself is) did not tell us a good story. In brief, we believe that there are at least two fundamental assumptions that Polkadot has got wrong regarding on-chain governance:
- That coin voters automatically have the best interest of Polkadot as a whole.
- That it’s in coin voters best interest to participate in on-chain governance, if they hold coins.
In a plutocracy system, it’s in the majority holders’ interests to gradually squeeze out minority holders – collusion. In an on-chain governance system, such power is unchecked, and the consequence of collusion is rather minimum. For example, in Polkadot treasury, the worst scenario, if such collusion is found out, will at most only be that such individual won’t get treasury funding in the future. This is in contrast to a real-world plutocracy system (i.e. company shareholders) where further fines and jail sentences can be threatened. In most countries, laws also require that management must act with the best interest of the company. Otherwise, voting rights can be stripped and the management can be discharged.
In essence, an external check-and-balance enforcement system must be present to counteract the above untrue assumptions. Such system must be outside of the Polkadot governance. This does not leave many possibilities:
- For a weaker enforcement system, we can do what the Cardano’s on-chain governance system did, who introduced a “Cardano constitution”.
- For a stronger enforcement system, Polkadot can probably itself voluntarily register as a “security”, and thus be subject to company shareholding and investment laws.
If nothing is done, due to simple game theory, we think that such activities like grifting and collusion will only become more and more common on Polkadot.
Polkadot has provided us a valuable data point in the landscape of blockchain governance system. An on-chain governance system, such as Polkadot’s, is not necessarily better than an off-chain goverance system, such as Ethereum’s. If in doubt, the latter probably gives (minority) investors more peace of mind because they won’t need to worry about being gradually squeezed out.
