Updates on Ars magna

Updates to transaction editor

Thu, 02 May 2024 00:00:00 +0000

The transaction editor needed an update. It experienced troubles with transactions in your wallet from the Conway era. Although that network upgrade took place a while ago, it didn’t really manifest any problems for some time. Truth is, we all take time to upgrade. I updated the serialization library that creates the transactions as well as added support for the Lace wallet IOHK’s in house web wallet. I didn’t do that earlier because they had errors with the error notifications from wallet to app and their token mint display was off.

Catalyst funding for project Wallet as 2FA

Fri, 01 Mar 2024 00:00:00 +0000

The results are in and my authenticator project received enough community support to sponsor its realization. I want to thank all supporters and wish to listen to your feedback as the project develops in the coming months.

Catalyst Fund 11 Proposals

Fri, 12 Jan 2024 00:00:00 +0000

In this round I submitted two new proposals, each to continue my work around the transaction editor webapp to extend it with a Native Script editor with Multisig & Script wallet and now to develop the authentication project with Crypto wallets for signup, login, and 2FA . I’m very pleased with my new proposals, yet I haven’t spent any time advertising them. In my most sincere hopes, I wish you help me with your support.

Collaborative transactions

Wed, 19 Apr 2023 00:00:00 +0000

It is finally possible. The transaction editor webapp has now a backend to synchronize with connected clients. That means you can have multiple wallets connected into a transaction and collaboratively create a transaction that merges/swaps funds between the wallets and all wallets must sign for the transaction to be valid. As always, I accompany every feature release with a video. A tutorial that shows you every step of the process for you to learn how to do it yourself.

Hardware wallet support on the transaction editor

Fri, 20 Jan 2023 00:00:00 +0000

Up until now the transaction editor supercharged the cardano-cli, allowing you to craft highly complex transactions in a declarative manner, and it was amazing! However, key management is out of scope from the CLI an consequentially was from the editor. That started to change 6 months ago with the introduction of state management , upgrading the editor into a wallet and making it more useful. Now it is better than ever before with the support for hardware devices.

Video demo for the web transaction editor

Tue, 29 Nov 2022 00:00:00 +0000

Because a video speaks a thousand pictures and a picture speaks a 1000 words. I released a video tutorial on how use your preferred web wallet and mint your Cardano tokens using the web transaction editor. As short as I wanted to keep it, it last 20min. There is a lot of value to it, and you get it for free. This application runs entirely on your browser, you don’t need even to open an account.

Transaction editor webapp now supports Token mint & burn

Fri, 04 Nov 2022 00:00:00 +0000

This is the second major update on the app, now it is possible to mint Mary Era Cardano Native Tokens. That means by directly letting your wallet construct the minting policy, you can now use the editor to mint or burn your tokens.

The UX starts to feel bloated, despite the minimalist design. There is no way around the fact that transactions on the Cardano blockchain can be feature rich. I know that general UX design principles say to use modals for specific features. However, I decided to stick with an interface, which has all inputs on the same page. It might feel bloated, it might be wrong UX, yet the nice thing about being part of the competition is that I get to propose my version of the solution and carve my place in the market.

Releasing MVP transaction editor webapp

Mon, 12 Sep 2022 00:00:00 +0000

Certainly, this project has taken way too long for delivery. I had to reconsider its design many times. It went from an ambitious self-sovereign goal of hosting all infrastructure to leveraging your current web wallet for all your interactions with the blockchain. Today with many wallet options, it seems a better choice and I can focus on my particular goal.

TL;DR: The editor is finally out, it has still many rough edges but you can try it with your favorite wallet. Find the link in this post or from the project page.

Releasing documentation ouroboros-network local state query

Thu, 14 Jul 2022 00:00:00 +0000

Ever wondered how to communicate directly to your Cardano node? Where you bound to the cardano-cli? Did you wrap it around your preferred language? Now I have a new way. Talk directly to the node. The node follows a network specification on how it communicates to other nodes and clients. You can implement that specification and talk directly to the node. I have done it, and documented the effort along the process.

Showcase State management

Sun, 12 Jun 2022 00:00:00 +0000

I have been silent for a while, publishing progress reports and demos is not as fun as programming and debugging. I released the latest update of cardano.el , which now uses an SQLite database to manage state. It is a massive increase in complexity, but it enables wallet like features. It keeps track of key files, script files and manages addresses. More over it now has an optional integration to Cardano-Wallet, the backend for Daedalus.

Demo: Delegation & staking rewards with the transaction editor

Sat, 19 Feb 2022 00:00:00 +0000

I uploaded a new demo on the Ars magna YouTube channel on how to register your stake, delegate to a stake pool and claim your rewards using cardano.el the transaction editor. In this video I show additional inspection features like reviewing the crafted transaction as it comes from the cardano-cli and the execution log where all issued commands are listed.

Secured funding from Catalyst

Sun, 13 Feb 2022 00:00:00 +0000

Earlier this week Catalyst released the results of Fund 7. I was pleased to find some of my projects received enough support for funding. Thank you to all of you who entrusted me with their confidence vote. Cardano.el the transaction editor Had a flawless score from the Community advisors 5.0, the only one on the Open Source Developer Ecosystem challenge, and ranked 4th in voting results. I’m overall happy about this.

Demo transaction editor: Mint and distribute Cardano Native Tokens

Sun, 30 Jan 2022 00:00:00 +0000

On the Ars magna YouTube channel I uploaded a demo on how to Mint Cardano Native Tokens using cardano.el the transaction editor This video shows you how to write a complex transaction that mints two Non-Fungible-Tokens (NFTs), with its minting policy, time-lock, Metadata information and direct distribution into targeted addresses. Everything in on step, everything up for the edit. If you like this project, what it offers and roadmap, make it a reality and vote for it.

Demo transaction editor: Key generation & spending transactions

Mon, 03 Jan 2022 00:00:00 +0000

I uploaded a new demo video on the Ars magna YouTube channel to demo cardano.el the transaction editor. This is a short video showing how to create new keys and their corresponding wallet addresses. Then it shows how to craft a spending transaction to move your funds out of some of your UTxOs into any desired addresses. Watch it here: This demo is now the short example on the cardano.el project page.

Ars Magna is online

Sat, 01 Jan 2022 00:00:00 +0000

This website is finally live, a bright light emerging out of the water as this post picture. Ars magna displays a collection of my current projects, goals and challenges building on Cardano. Everything from a weak idea to a running project. It provides a constant reference of my work and is openly accessible, contrary to the proposals I write on Ideascale for project Catalyst. This website launches after lots of struggle trying to create a minimalist theme, it was an unnecessary amount of Yak shaving.
