Polkadot's Decentralized Future Takes Shape as JAM Migration Targets 2027 Launch

Polkadot's JAM migration timeline has been updated to target a 2027 production launch, according to an official post by Parity Technologies.

This shift will bring parachain functionality away from the relay chain and towards JAM, described as a more streamlined setup for core validation duties.

A separate report ranked Polkadot's decentralization score at 178, with the Nakamoto Coefficient measuring how many independent actors would need to cooperate to compromise the network.

The DOT price fell below one dollar, down 4.06 percent over the past 24 hours, according to CoinMarketCap data from September 16, 2026.
