Compile smart contract

Before proceeding further, make sure that the top folder looks like this:

power
power-ui
sc_vote_simple

If ok. Go to console in folder sc_vote_simple and do and type the compilation command:

cargo build --release --target wasm32-unknown-unknown

Then you will need to go to the directory in which the compiled WASM file appeared. It will be further located at the following address:

cd target/wasm32-unknown-unknown/release/

Then launch the file size reduction utility:

wasm-snip ./sc_vote_simple.wasm -o sc_vote_simple.wasm

And then start compression:

lz4 -16 -f sc_vote_simple.wasm

As a result you get sc_vote_simple.lz4 file, which you will list (deploy) in the blockchain.
