⚖️ Three voting models compared

2 min read

Key takeaway

Linear (token-weighted) voting hands the largest wallet the microphone; quadratic and time-weighted voting price influence differently — SDA Token itself does not use quadratic voting.

Note on SDA Token: SDA Token governance does not use quadratic voting. Quadratic and time-weighted models are described here for comparison, so you can see what changes when influence is priced differently. Treat this lesson as background, not as a description of the SDA voting rules.

Different voting systems balance competing priorities: proportional stake representation, minority protection, and preventing whale dominance. Understanding these models helps you participate effectively.

Simple Token-Weighted Voting

The most straightforward model: 1 token = 1 vote.

Aspect Description
Mechanism Each token holder votes proportional to holdings
Pros Simple, aligns with economic stake, familiar to investors
Cons Large holders ("whales") can dominate decisions
Best For Routine operational decisions, early-stage governance

Example: Alice (100,000 tokens) vs Bob (1,000 tokens). Alice has 100x voting power. On a project selection vote, if Alice votes Yes and Bob votes No, Alice's preference prevails unless 100 other Bob-sized holders unite against her.

Quadratic Voting

Cost to cast votes increases quadratically: 1 vote costs 1 token, 2 votes cost 4 tokens, 3 votes cost 9 tokens, etc. This reduces whale dominance while still reflecting economic stake.

Votes Desired Token Cost Marginal Cost
1 1 1
2 4 3
3 9 5
5 25 16 (from 3 to 5)
10 100 75 (from 3 to 10)
100 10,000 9,900 (from 3 to 100)

Try the numbers yourself: the voting power calculator compares linear and quadratic power for any two stakes.

Time-Weighted Voting

Voting power increases with holding duration, rewarding long-term commitment. A token held for 2 years might have 2x the voting power of one held for 1 day.

Holding Period Vote Multiplier Example
0-30 days 1.0x 1,000 tokens = 1,000 votes
31-180 days 1.2x 1,000 tokens = 1,200 votes
181-365 days 1.5x 1,000 tokens = 1,500 votes
1-2 years 2.0x 1,000 tokens = 2,000 votes
2+ years 2.5x 1,000 tokens = 2,500 votes

Rationale: Renewable infrastructure requires decades to realize full value. Time-weighting aligns voting power with commitment to long-term success, reducing impact of short-term traders.

Choosing between them

Most real projects mix all three: linear weighting for routine operational votes, a quadratic or reputation-weighted rule for capital allocation, and a time multiplier so a wallet that bought in yesterday cannot outvote one that has carried the risk for two years. Whichever rule a DAO picks, it lives in a smart contract and can only be changed by a vote held under the old rule — which makes the voting model the one decision that constrains every later decision.
