cross chain support, large scale transactions and lack of unified oracle problem

[cryptokangaroo]

 What projects are effectively trying to tackle those? When is some progress expected?


1)Increasing demand for cross chain support, handling the compatibility problems for smart contract data

2)Insufficient support for large-scale transactions

3)Lack of unified and effective Oracle. in a smart contract environment we need to obtain external data/knowledge, and the validity/authethenticity of such data/knowledge becomes the bottleneck and obstacle of smart contracts.
