Cardano: Shelly Testnet progress, working on Microchip that would give crypto a cash-like experience, Cardano among members of a new lobbying group that met with the SEC

Biweekly update 14th May — 29th May

Hello, dear community! Paradigm is with you again, and we want to share the news that has happened with Cardano in the past two weeks.

It is worth starting with the news of the recent POSA (The Proof of Stake Alliance) and SEC (U.S. Securities and Exchange Commission) meeting. The alliance looks to provide regulatory clarity around how securities laws at the SEC apply to certain blockchains. The founder of POSA spoke at Consensus Distributed about their goals with the SEC as well as a white paper that was published, and also how they hope to provide standards as well. Originally reported in CoinDesk, the group’s founder, Evan Weiss stated the idea the group wants to convince the Securities and Exchange Commission (SEC), that entities using stake networks should be seen as service or infrastructure, rather than financial product providers. We attached a link to the original article in the body of the report, but you can also familiarize yourself with our section “Сrypto Regulation”, which summarizes the latest changes in regulatory policy in all countries of the world!

Cardano is all about development. You can follow the full list of updates in the Weekly Development Reports provided by the team. Аccording to Сointelegraph, Cardano is working on a crypto-native microchip that would enable crypto transitions without internet access, potentially delivering fiat-like experience to the hundreds of millions around the world.
The Shelley Incentivized testnet is going strong! Each week they publish all an update on the progress of the Shelley Haskell testnet on the forum. Also, the team released the first of brand new video updates, with Cardano head of delivery Christopher Greenwood. You can check it out if you’d like a deeper dive into what has been happening during our last development sprint. The development team had a very productive week. Block production is now fully underway. Key Evolving Signatures (KES) are now part of the testnet and the hardfork combinator 5 is merged. The wallet is also being integrated with Shelley node.

3rd ZKProof Workshop — Home Edition finished on May 22. Listeners joined Charles Hoskinson for a special panel focused on “Industry, Deployment, & Adoption” and IOHK Researcher, Markulf Kohlweiss, for an exciting talk on ZKPs enriching ledgers with private smart contracts.

Binance US has added ADA to the Buy Crypto experience, bringing the total to 14 tokens. ELLIPAL has also added ADA to its Buy Crypto function! You can now buy ADA using bank cards and Apple pay right on the ELLIPAL App.

Shelley Haskell Testnet update w/e 22 May. Each week, the team gives you all an update on the progress of the Shelley Haskell testnet. They’re about ten days in now and things are very positive. This week was all about blocks. More specifically, implementing and refining the block production process. To support this key element, as of the end of 22 May, they’ll have shared 5 foundational exercises. These have all been designed to iteratively take pioneers through the process of setting up a stake pool on the Haskell network, step by step. Think of these a little like an instruction manual, that coaches on the core components as you assemble everything.

According to WEEKLY DEVELOPMENT REPORT (15th May — 22th May) Cardano team has been doing the following operations:



Last week the team continued to work on hardware wallet integration, as well as finishing an overhaul of Japanese translations across the entire Daedalus user interface.

In the scope of regular maintenance tasks, the team has been working on improving the structure of the general dialog component and updating ReactJS dependencies.

The team has also finished the implementation of the wallet recovery phrase verification feature for Incentivized Testnet wallets, which will be released in the next version of Daedalus for the Incentivized Testnet.


Last week the Adrestia team has been working on the initial integration of the Cardano node in Shelley mode. New functionality includes the partial wiring of the underlying engine to the API, an adjustment to the networking layer to deserialize Shelley-specific data-types, and a test bench for running a self-node with faucets when running integration scenarios.

The team has also been working on implementing transaction support, although the binary formats and other specifics of the implementation are still being finalized on the node.

Work was done this week to reduce code duplication by re-using some addresses within Cardano-wallet. However, it is not possible to re-use all of the addresses due to some refinements required to create a more efficient platform.

More progress was made on the API this week, particularly the fee estimation rework. The API now returns a lower and upper bound for fees, backed by a statistical approach to get more reliable results, especially on bigger UTXOs.

The team also significantly reduced both the time and space required to store sequential addresses and reduced the space needed to store random addresses without adding any significant time to the operation. Normal wallets will not notice much difference, but these reductions will have a significant impact on larger wallets.

Finally, the latest Docker tag now references the latest code on the master branch, rather than the latest ‘stable’ release.


Last week the networking team has been fixing an issue that caused high CPU usage on macOS systems, which turned out to be the result of a bug in the Glasgow Haskell Compiler (GHC).

The team also made progress towards a bidirectional multiplexer this week, as well as calculating the bounds of header sizes ahead of the upcoming Shelley release. This allowed the team to verify that the existing ingress queue limits will work with the current set of cryptographic primitives in use for Shelley.

Elsewhere, the team has been working on a server-side termination message for the transaction submission protocol, which allows requests to be made to the consensus layer to cooperatively shut down all mini-protocols.

Finally, the team worked on refactoring the instantiation of the Ouroboros network protocol during consensus. Consensus protocol applications can now make decisions on the negotiated version during the handshake protocol.


The DevOps team supported the deployment of a new explorer version this week, as well as helping the Friends and Family testnet development team with IOHK stake pool registration.

The team worked on the systemd service socket activation integration for Cardano node with NixOS this week. Work has also been done on the initial faucet integration for the Shelley wallet, and the team has been building Rust code with Naersk for Jörmungandr and other Rust libraries. They’ve also been integrating Rust libraries with haskell.nix.


Last week the team made improvements based on feedback from the Friends and Family phase of the Shelley Haskell testnet, including updates designed to improve the user experience and interface.

The team also worked on debugging transaction generation, reconstructing the timeline of block creation and diffusion using benchmarking data, and improving the automation of the benchmarking pipeline using Nix.


Last week the Plutus team made it easier to update the benchmarks by adding a PLC source file, together with the serialized version. In addition, they upgraded the Nix packages on the deployment machine and made improvements to tidy up line endings within the code. Finally, they made updates to the state transfer during static analysis. The Marlowe team moved static analysis into the Marlowe project and added warnings for empty choice lists in the Marlowe Playground. They also worked on updates to the Isabelle build task for Nix/Hydra.

Some interesting article worth reading:

  • Building new standards for privacy and scalability by Brian Mckenna. IOHK joins the conversation around zero-knowledge proofs at the ZKP Workshop. In the age of information capitalism, data is a commodity which needs to be protected on an individual and global level. Every time someone makes a purchase, logs into an account, or accesses a website, metadata is connected to their individual IP address. Mass amounts of information move around the world every second but if it is not secured through encryption it can be exploited. The downstream effects of this can be benign, such as receiving targeted marketing. Or they can be dangerous like spreading political propaganda.

Upcoming Events:

There are currently no offline meetups planned and/or supported due to the global ongoing COVID-19 pandemic.

In the meantime, the Cardano team has gathered feedback from the community for possible solutions and recommendations to hold e-meetups and some already held have been quite successful! You can check this out on forum post

Work scope


Plutus is a purpose-built development and execution platform using the functional programming language Haskell. Designed to enable the creation of smart contracts on Cardano, Plutus brings the inherent benefits of functional programming — such as reduced ambiguity and easier testing — to smart contracts.

All the work on Plutus is visible in the Plutus GitHub repository, and the Plutus Playground testbed is available for users to try creating their own smart contracts in Plutus.


While Plutus is a high-level language for developers, Plutus Core is a low-level scripting language that runs on both Cardano’s settlement layer and computation layer, controlling interactions between scripts and the blockchain itself. All on-chain functionality of smart contracts written in Plutus compiles to Plutus Core, which retains all the benefits of functional programming while remaining simple and concise. Where Plutus Core is implemented in the settlement layer, it is done so in the simplest way possible, improving security by minimizing potential attack vectors.


Marlowe is a domain-specific language (DSL) for creating financial smart contracts, designed to be accessible to non-technical individuals such as business engineers, subject experts, and financial analysts. Using Marlowe, even someone without any programming experience can create executable smart contracts that interact with real-world data and deploy them on its built-in Cardano emulator, and eventually the Cardano network itself. Whilst Marlowe is necessarily a high-level language, it is built on Plutus and Haskell and continues to benefit from all the assurances that functional programming provides, without affecting ease of use.

All the work on Marlowe is visible in the Marlowe GitHub repository, and the Marlowe Playground emulator is available for users to try creating their own financial smart contracts using a simple web-based interface.


PlutusFest was held at the University of Edinburgh in December 2018 to announce and promote the Plutus and Marlowe programming languages. Interested members of the public and academia gathered for two days of talks and presentations by IOHK engineers, most of which were recorded and can be watched on the IOHK YouTube channel.


Two free Mooc courses have been released on Udemy covering the Plutus and Marlowe programming languages. Created and managed by IOHK’s in-house education team, the courses provide an introductory resource for anyone interested in learning how to experiment with smart contracts using Plutus and Marlowe.


The introduction of a multi-currency ledger model into Cardano will allow the network to support additional cryptocurrencies in an ERC20-like way, but cheaply, more securely, and without the need for a complex scripting system thanks to native support in the settlement layer. Not only will users be able to create their own fungible tokens on the Cardano network, but a multi-currency ledger will also allow for tokenization with the creation of non-fungible tokens, plus easier integration with smart contracts involving multiple cryptocurrencies.


KEVM is a high-quality, formally-verified smart contract virtual machine compatible with the Ethereum virtual machine (EVM). Formally specified in the K framework, the KEVM uses formal semantics for elements such as the configuration and transition rules of EVM, resulting in a more secure virtual machine for smart contracts. IOHK paused its collaboration in the K framework project in order to focus on other priorities, but is enthusiastic about the vision and may participate again in the future.


The IOHK education team have worked in conjunction with Plutus language architects to create an introductory Plutus ebook. The ebook is designed to educate beginner Haskell developers on the fundamentals of the new Plutus smart contract language and uses real-world examples to illustrate the potential applications of Plutus.
