Coda is a cryptocurrency that uses a succinct blockchain that is enabled through the recursive composition of zk-SNARKs. For clients, this means they can verify the chain with only a few kB of data which opens up exciting opportunities for scalable blockchain applications.

Coda recently launched their public testnet and encourages users who want to help develop the protocol to join the testnet and complete various weekly challenges. While Coda has a traditional command-line interface (CLI) that will be familiar to anyone running a full node implementation, e.g. Bitcoin Core, it also exposes a GraphQL API that we will explore in this article.

With the launch of 2.0.7, zcashd now includes full support for the Insight blockchain explorer. The Insight explorer, which will be familiar to those who have used one of the many popular block explorers it powers, was developed by Bitpay as part of its bitcore suite of tools. The tool, released under a permissive open-source license (MIT), contains many development tools to “build bitcoin and blockchain applications” but we will concentrate on installing the explorer portion for this article which has been ported to support Zcash.

The Raspberry Pi, in particular, has been popularised for cryptocurrency nodes by the likes of the Casa Node and RaspiBlitz which constitute full Bitcoin/Litecoin and Lightning nodes.

WinZEC (formerly Zcash4Win) was the first port of the official Zcash client (known as zcashd) to Windows. As a result, it still powers a large proportion of the Zcash nodes on the network for those who wish to use shielded transactions on a Windows machine. WinZEC is comprised of two major components, the Swing wallet GUI(the interface that you see when you open WinZEC) originally by vaklinov and the Windows port of zcashd by radix42.
