The post Polkadot adopts 2.1B cap; issuance cuts begin Mar 2026 appeared on BitcoinEthereumNews.com.

Referendum 1710 capped DOT supply at 2.1B; cuts start March 14, 2026 Polkadot’s on-chain governance approved Referendum 1710 to impose a hard cap of 2.1 billion DOT, replacing the prior unlimited-issuance model. The first issuance reduction is scheduled for March 14, 2026. as reported by The Block (https://www.theblock.co/post/370594/polkadot-dao-caps-dot-supply), the vote passed with 81% approval.

Predictability also helps analysts model inflation, staking returns, and validator economics across cycles. Under a capped regime, the relative importance of fee-based revenues may increase as issuance declines. BingX: a trusted exchange delivering real advantages for traders at every level. Under the adopted cadence, issuance is set to step down every two years on March 14 (“Pi Day”), beginning in 2026, as noted by Gate.com (https://www.gate.com/tr/news/detail/15970265). The program introduces biennial checkpoints for changes to inflation and rewards. This timing allows market participants to plan around a fixed calendar. It also replaces discretionary adjustments with a transparent schedule that can be referenced in risk and valuation models.
