Cardano serialization library in Go

We want to create Cardano serialization library for Go.

Among our members are seasoned programmers with vast blockchain programming experience, including Golang.

Go programming language has been in the top 5 GitHub's most used programming languages for several years. https://madnight.github.io/githut/#/pull_requests/2020/4

Unfortunately, it is currently missing many essential development libraries that would encourage people to develop on Cardano blockchain.

We want to create Cardano serialization library for Go.

Serialization libraries make it easier for developers to work with data structures used in Cardano's blockchain implementation, such as creating and derivating keys, managing metadata and assembling transactions.

## Deliverables
We will start an open-source Cardano serialization library for Go with the following support in the first release:

• Support derivating keys from ED25519-BIP32 and BIP32
• Support all current types of Cardano addresses
• Cardano transaction metadata structures manipulation
• Transaction assembling including fee estimation

We estimate it will take us 2 months from the funding to release the first stable version.

## Relevant experience

Among our members are seasoned programmers with vast blockchain programming experience.

Five Binaries is an infrastructure development company. We're Cardano pioneers - with the first Cardano block minted on an aeroplane, first stake pool on the ITN and the first Shelley transaction on the mainnet.

We are trusted by customers such as Emurgo, Trezor or Ergo Foundation. To get in touch or find more information about us, please visit https://fivebinaries.com/.

## Budget

We estimate it will take us 50 engineering-hours to complete the deliverables and we plan to allocate three people to this project.

Our rate, which comprises of our engineers' salaries, infrastructure costs, office rent, accounting and taxes is 100 EUR per hour.

We pay our people well, because they are both skilled and exceptionally experienced in the industry. And last but not least, because we respect them and want them to feel good and appreciated while working on Cardano.
