币界网报道：Polkadot's DOT token surged to $45.12, reaching its highest price point since November 2020, marking a 22% weekly gain amid renewed investor interest in the interoperable blockchain platform. The rally follows Polkadot's recent technological upgrades, including the launch of its Join-Accumulate Machine (JAM) Gray Paper and successful integration of asynchronous backing, which improved block production efficiency by 8x. Analysts attribute the price momentum to growing adoption of Polkadot's parachain ecosystem, with active addresses increasing 48% quarter-over-quarter to 5.6 million. The network's treasury also shows robust activity, funding 300+ projects with $60 million in DOT this year. Market observers note DOT's breakout coincides with broader crypto market recovery, though some caution about potential volatility as the token approaches its all-time high of $55.
