This Week In TurtleCoin (FEB 19, 2019)

Two roundups in three days, who knew we’d be so lucky! Back on schedule!

Developer Updates

TurtleEDU – Thanks to all of the students who have submitted spelchex and currectshuns forr TurtleCoin 101 🙂 Fexra and I have had a fun time hunting down errors and resetting passwords. The email system is still kind of a joke (it uses a gmail integration that worked one time, we swear), so please write down your passwords until we figure out something to fix it. A lot of you have been asking about when followup classes will be ready, and I’ve begun gathering information about what people want to see in the Beginner’s Git class which goes over the Git version control tool we use. If you have suggestions relevant to the Git class, please post them in #edu_general. Since the goal of the first class was to turn people into competent TurtleCoin users, the goal of this next class will bring everyone to the level where they should feel comfortable contributing on Github, which as you may know is how you get your pink “Contributor” role in Discord. – Rock

Turtle Swap Protocol Whitepaper – I had the chance to speak with Napoleon (from TRTL and VELD) and we’re fleshing out some of the concepts laid out in the Turtle Swap Protocol Whitepaper as it appears he’s been working on developing a similar concept for Veldspar. The concept aims to enable wallet to wallet transfers of multiple currencies without touching an exchange, and in this case it’s particularly interesting as it’d involve a swap outside of a cryptonote network. I’m hesitant to call them atomic swaps just yet, but the whitepaper gives the gist of how it’d function at a conceptual level. We’re looking for other devs to collab with on developing the next draft of the whitepaper, so if you’re the type of person who’s interested feel free to stop by the chat in #dev_general or create an “issue” in the turtle-labs repo. – rock

Node.js Goodness For TurtleCoin – Some of you may know about the TurtleCoin Utilities package that Zpalm and I have been working on to make it very easy to perform a lot of the CryptoNote cryptographic functions in Javascript.

The TurtleCoin-Utils package can be used in browser, in Node.js, react-native, and has TypeScript bindings available.

Using this package, it’s very easy to create new wallets, encode addresses, decode addresses, handle integrated addresses, scan transactions for your funds, create new transactions, and etc.

This package is very powerful and provides a nice way for those looking to get started in TurtleCoin development easy to follow source code that guides you along the way. It is also part of the foundation of TurtlePay payment processing and is used heavily by Zpalms’s wallet backend in JS.

Running all that crypto can be a bit slow in raw JS, but no worries, help has arrived.

The TurtleCoin Crypto module for Node.js is a native C++ addon for Node that provides significantly faster cryptographic routines for use with TurtleCoin-Utils and other packages. It is very generic in handling CryptoNote related cryptography so many projects besides TurtleCoin may find good use of it. It exposes a lot of the underlying cryptography that the TurtleCoin Utilities needs as well as a few extras.

The TurtleCoin Crypto module is automatically loaded as an optional depenedency for TurtleCoin Utils which has the utils package us it for the crypto (30-40x faster than the native JS code) and falls back to the native JS if necessary.

TurtlePay Updates – We’ve been working hard implementing some updates to underlying packages (see above) to speed up the processing of the one-time wallets. In addition, we’ve been working on extending out some of the functionality of the blockchain API to support additional endpoints that provide the necessary data for working with additional wallets like Zedwallet++, wallet-api, walletbackend-js, and the mobile wallet that Zpalm is working on.
