This is an experimental POC for deploying a canister written in Go on the IC. It contains an hello world example that works, but there are likely to be problems using any libraries.

1. Install Tinygo from source(https://tinygo.org/docs/guides/build/) with the following patch:

   (I used commit https://github.com/tinygo-org/tinygo/commit/377415a6c3158d5cefe8cd46c592b144053593aa)

   This patch will enable the bulk memory operations Wasm feature and define a memory instead of importing one.

2. Install dfx (recommended using dfxvm).

1. Start a local dfx subnet.

   dfx start --clean --background
   

2. Build, deploy and send a message to the canister by executing run.sh. This assumes tinygo was installed to ~/go/bin/tinygo.
