币界网报道：Cardano (ADA) has experienced a significant surge in development activity over the past eight weeks, marking its highest level in 26 months, according to data from Santiment. The blockchain's GitHub commits have spiked, reflecting heightened developer engagement and project updates. This uptick coincides with ADA's price rally, which saw a 25% increase in the same period, currently trading around $0.60. Analysts attribute the momentum to upcoming network upgrades, including the highly anticipated "Voltaire" phase, which aims to introduce decentralized governance. Cardano founder Charles Hoskinson has also been actively promoting the platform's scalability and interoperability features, fueling investor optimism. Despite the bullish indicators, some market watchers caution that ADA's price remains volatile, with resistance levels near $0.65 posing a key challenge. The broader crypto market's recovery, led by Bitcoin's rebound above $70,000, has further bolstered sentiment around altcoins like Cardano. Institutional interest in ADA has also grown, with Grayscale's Cardano Trust reporting increased inflows. Meanwhile, the network's total value locked (TVL) in decentralized applications continues to climb, surpassing $400 million as more DeFi projects launch on the platform. The recent developments underscore Cardano's evolving ecosystem, though long-term sustainability will depend on mainstream adoption and continued technical execution.
