The Polkadot DAO has successfully passed Referendum 1710, implementing a cap on the total supply of DOT tokens at 2.1 billion. The proposal received overwhelming support, with 81% of votes in favor. This decision marks a significant shift from the previous model, which allowed for the minting of 120 million DOT tokens annually without a cap. The new policy aims to reduce emissions by decreasing the issuance of new DOT tokens every two years.
