space-profit model shift in blocks, and ambitrum and megaeth began self-study applications

Castle Labs Research, a deep-done report, noted that the gap between chain and application fees was widening, making block space difficult to sustain high valuations. Projects such as arbitrum and polygon raise income through ecological expansion, while megaeth and sophon shift to self-study applications to internalize benefits. Despite some success in the ultra-chain model, such as timeboost and superchain, income declines after the departure of eco- and token-based performances. The new chain needs to internalize value through self-construction applications, stable currency, etc., to increase actual usage and to form a vertically integrated income model。
