How to extract data written into binary cache?

Question

The documentation says that  the binary cache allows large pieces of data to be written and read from a chain but what is the api for reading it?

Answer 1

The whole point of the binary cache is that you don't read and write it via APIs, but rather access it directly from the file system. It's covered in "Getting Started" but we should make this clearer in the API documentation. In the meantime the file location is here:

~/.multichain/[chain name]/cache/[cache identifier]
