Polkadot news today centers on a governance proposal to shrink the network's active validator set, while DOT trades at $0.9043, down 2.36% over 24 hours.
Referendum 1966 proposes a smaller validator set
Referendum 1966 would remove 100 of the network's 600 validator slots, as the first step in a three-stage plan to reduce the active set to 320. Polkadot wants to shrink its active validator set in three stages from 600 to 320, and Referendum 1966 starts the process from around November 10. Validator rewards would shrink in step with the headcount, since the proposal reduces the validator budget in the same proportion.
If voters approve, the change would apply from November 10, 2026. For DOT holders, the key question is where their own DOT is staked, because nominations to validators that are dropped could leave those tokens unrewarded. Nominators have a short window to review their choices before the cutoff.
The proponents argue that fewer validators can handle heavier duties. By the end of 2026, validators are expected to run collators for Asset Hub and People Chain, answer light client requests, and serve RPC requests from the Polkadot App.
Polkadot news today: $1.38 million treasury loss
Polkadot's treasury lost about $1.38 million after a security patch failed to reach production. The security flaw had been identified and corrected in the codebase in June but never reached the affected production systems, according to an incident report from Parity Technologies, the blockchain infrastructure firm focused on the Polkadot and Kusama ecosystems.
The attacker targeted dotUSD, the newly launched DOT-backed stablecoin. The attacker manipulated Polkadot Asset Hub's cross-chain messaging system to reduce dotUSD's recorded supply without removing tokens from users' accounts. That mismatch distorted prices in the network's DOT/dotUSD liquidity pool, allowing traders to exchange dotUSD for DOT at artificial rates. Reports on the incident were published on November 4, and the treasury's exposure was framed as a pricing deviation in the trading pool, which the failed patch caused.
