Web 3.0 promotes the implementation of distributed economic models such as NFT,Defi,cryptocurrencies,and decentralized autonomous organizations(DAOs).The feature of Web 3.0 co construction and sharing is different from that of Web 2.0 where users are only users,enabling users in Web 3.0 to actively participate in co construction and co governance,using blockchain technology and smart contracts to formulate and implement rules in the organizational form of DAO,and sharing the value of sharing platforms or protocols.
区块链等技术的参与。区块链是Web3.0最突出的关键技术，助力安全、透明和防篡改的交易。Web3.0同时也包含其他机制促进和推动去中心化，如云计算、AR Cloud和其他网络空间关键技术等；

最后，在symbolic_fn中，我们可以看到插值算子是怎么样被映射成多个ONNX算子的。其中，每一个g.op就是一个ONNX的定义。比如其中的Resize算子就是这样写的：
return g.op("Resize",
input,
empty_roi,
empty_scales,
output_size,
coordinate_transformation_mode_s=coordinate_transformation_mode,
cubic_coeff_a_f=-0.75,#only valid when mode="cubic"
mode_s=interpolate_mode,#nearest,linear,or cubic
nearest_mode_s="floor")#only valid when mode="nearest"
