Summary

Polkadot’s DAO passed Referendum 1710 with 81% approval, establishing a 2.1 billion maximum supply for DOT and replacing its inflationary issuance model. Previously, 120 million DOT were minted annually with no supply limit, projecting over 3.4 billion tokens by 2040. The new model reduces issuance in fixed steps every two years starting March 14, shrinking from 120 million in 2025 to below 20 million by the early 2030s, with supply stabilizing near 1.91 billion by 2040. This move aligns Polkadot with scarcity-focused frameworks like Bitcoin’s halving events. Alongside this change, Polkadot launched the Polkadot Capital Group on August 19 to connect Wall Street firms with its blockchain ecosystem. DOT traded at $4.18 after the announcement, down 4.6% in 24 hours, but technical analysis suggests a potential rebound toward $6.30–$13 if support levels hold.

Terms & Concepts
  • Decentralized Autonomous Organization (DAO): A community-led governance structure using blockchain-based voting to make decisions without centralized control.
  • Proof-of-Personhood: A proposed consensus model where network participation is based on verified human identities rather than token stakes or computational power.
  • Hard Cap: A fixed maximum limit on the total supply of a cryptocurrency, preventing indefinite issuance and ensuring scarcity.
