- gofmt - Gofmt checks whether code was gofmt-ed. By default this tool runs
with -s option to check for code simplification
- goimports - Goimports does everything that gofmt does. Additionally it checks
unused imports
- golint - Golint differs from gofmt. Gofmt reformats Go source code, whereas
golint prints out style mistakes
- checks the uncommented exported functions & types
Update the code to fix the lint checks.
hermez-node 
Go implementation of the Hermez node.
