What it costs to lose a vote on the Internet Computer

The Internet Computer, built by the DFINITY Foundation (@dfinity), is governed by an on-chain voting system called the Network Nervous System (NNS). Anyone who wants to change the protocol has to put a proposal to a vote, and a failed proposal comes with a price tag paid in $ICP.

How NNS proposals and neurons work

ICP holders take part in governance by locking tokens in "neurons". According to the Internet Computer learning hub, once a neuron is locked for more than six months it can both submit proposals and vote on them. Voting generates rewards, based on how active a neuron is.

A proposal is a suggestion to update the protocol. Other neuron holders then vote, and ICP developer documentation says adopted proposals are executed automatically by the NNS governance canister. Voting typically stays open for four days, extending to up to eight days if votes are contested.

The rejection fee

To avoid being flooded by useless proposals, the ICP learning hub says a proposer pays a fee of 25 ICP. The fee is returned if the proposal is adopted, but not if it is rejected. The charge is placed against the proposer's neuron balance, so the neuron must hold enough to cover it.

The rule does not judge intent. A good-faith idea that voters turn down still costs the proposer the fee. The developer documentation also states that a rejection fee is burned if the proposal fails.

The figure has not stayed fixed. The Internet Computer wiki describes the fee as a governance parameter that can change, and notes that some older documentation quotes 10 ICP, which it calls out of date. The same page currently lists a rejected proposal as costing 50 ICP and advises checking the live value before staking. Readers planning to submit a proposal should therefore confirm the current on-chain parameter rather than rely on any single published number.

The mechanism reflects a trade-off common to open governance systems. Low barriers let any qualified participant propose changes, while a cost for failure discourages spam and low-effort submissions.
