Referendum #1710 passed with 81% of voters in favor of capping the network’s token supply at 2.1 billion DOT on 14 September. This is the first time Polkadot has implemented a fixed issuance limit, a move seen as crucial to strengthening the token’s scarcity and long-term value proposition.
Tighter Monetary Policy to Curb Inflation
Under the new rules, DOT’s inflationary issuance will be gradually reduced. Instead of continuing the current model, which adds a fixed 120 million DOT each year and could have pushed supply past 3.4 billion tokens by 2040, the updated framework will taper issuance every two years.
By 2040, the circulating supply is now expected to reach approximately 1.91 billion DOT before eventually locking at the 2.1 billion cap.
This policy shift aims to combat inflation, align incentives for long-term holders, and introduce a clearer monetary structure for DOT’s role in staking, governance, and parachain auctions.
DOT’s Decentralized Governance in Action
The proposal was implemented through OpenGov, Polkadot’s governance framework launched in 2023. OpenGov empowers all token holders to directly propose and vote on protocol changes, reinforcing the project’s commitment to decentralized decision-making.
The outcome also highlights a strong community consensus on monetary policy, a rare achievement in blockchain governance.
DOT’s Market Reaction
Despite the long-term bullish implications, DOT’s market price fell in the short term. According to CoinGecko, DOT slipped 5.59% in 24 hours following the announcement, trading at $4.20 with a total market capitalization of $6.3 billion, ranking it 34th among all cryptocurrencies.
Analysts suggest the initial dip may reflect profit-taking and short-term uncertainty, while the supply cap could bolster DOT’s appeal as a more deflationary, store-of-value asset in the long run.
