What is ARTIS?

ARTIS is a Blockchain built to serve as a foundation for decentralized applications by providing an open-source ecosystem sharing many similarities with the Ethereum Blockchain and therefore enriching the application space for new business models. Furthermore, ARTIS will be one of the first Blockchains utilizing the Plasma design pattern to connect to Ethereum.

Is ATS a coin or a token?

ARTIS as a Blockchain network has its own base coins called "ATS". They are used to pay transaction fees on the network and can be streamed. ATS are NOT ERC-20 Tokens.

Is ARTIS connected to Artis Turba?

ARTIS has no connection to "Artis Turba" in any way. Information about the ARTIS Blockchain will only be published on and our official social media channels.

Is ARTIS money/currency or a smart contract platform?

ARTIS is compatible with the Ethereum development ecosystem (EVM & code base) and provides the same Turing complete smart contract functionality but has key differences to Ethereum in terms of the consensus mechanism and coin emition model.

Why don't you use an Ethereum-based token instead? What's the need for a blockchain?

ARTIS will be one of the first blockchains that will utilize the Plasma design pattern to connect to Ethereum. ARTIS enriches the whole blockchain ecosystem by addressing three major problems: Scalability, energy consumption and a fair distribution of coins. ARTIS also introduces the concept of 'Streems' that will literally enable cash to flow much like fluids. Also, Ethereum-based Tokens would still be using the energy intensive PoW (Proof of Work) consensus which ARTIS does not. Those are key differences in scope, functionality and purpose.

Is ARTIS competing with Ethereum?

No. The future will have many interlinked Blockchains while the technology and applications are still evolving. By linking ARTIS with Ethereum, ARTIS becomes part of the same ecosystem and is collaborating and contributing, not competing.

What is the lab10 collective eG and who is behind this organisation?

The lab10 collective e.G. is a cooperative based in Graz, Austria. It is the organization that is developing - among other projects - the ARTIS Blockchain network. All of our projects are supporting the transition to a free, fair and educated society. We currently consist of 38 members and are a purpose-driven and profit-oriented cooperative. We always seek new talent and like-minded people to join our efforts. Meet the team and find out more at

How is ARTIS sustainable?

As opposed to Blockchains that use the energy-intensive Nakamoto consensus algorithm (Proof of Work), ARTIS will work with a combination of PoS (Proof of Stake) and PoA (Proof of Authority) consensus mechanisms, specifically with the so called "Honeybadger". Not only does this give the Blockchain the functionality it requires (fast block time and finality), but it also saves a LOT of energy without compromising on security or speed.

How do you implement decentralized governance?

For technical suggestions and improvement proposals, the global developer community can contribute through open source platforms (similar to how Ethereum uses EIP (Ethereum Improvement Proposal) to manage suggestions). For non-technical proposals, ARTIS plans to use its trusted network in combination with Liquid Democracy to allow decentralized decision making.

What can I build on top of ARTIS?

ARTIS allows all sorts of business models which will work on a smart contract platform. Time based payments, like subscriptions, wages or installments can also leverage the power of STREEMs, a form of value exchange so far unique to ARTIS. The ARTIS Blockchain Network is built for the deployment of DApps and offers significant advantages over using Ethereum for this purpose: Faster block times and a less congested network. Lower and more predictable transaction fees while being fully compatible with Ethereum in terms of code. In short: If your code runs on Ethereum, it will run on ARTIS. If you as a developer have specific questions for integration please contact our team directly. Your best bet for this is Gitter.

What's the use of Streems, if I can have instalments?

In short: Convenience. Just imagine a service where you pay-per-use like consuming media or urban parking. When you start using the service, you don't always know for how long you are going to use it. You just have to start a STREEM (automatically) and end the STREEM (automatically). Transaction costs arise only at the start and at the end. In other use cases, STREEMs avoid risk asymmetry caused by discrete payments in advance or afterwards.

What is the most simple real-life use case for Streems?

A simple example is paying for parking: As you park your car, the parking spot sends a trigger and your car (its wallet) streems money automatically for the service. It stops the Streem once you leave the parking lot.

Does ARTIS only support Streems or also discrete payments?

Discrete payments are available. On a technical level they are handled differently than Streems but they are of course possible.

Can I deploy my Ethereum DApp on ARTIS?

Yes. Because ARTIS shares the same code base with Ethereum and uses the EVM, you can deploy any Ethereum-based application on ARTIS as well and use Ethereum development tools.

When can I use the ARTIS blockchain?

Since the launch of the ARTIS mainnet, the blockchain is operational and ready to be used by anyone who wants to interact with it. The first DApps have already been launched and more are coming. If you are the developer and want to deploy your code on ARTIS, please get in touch with our team via Gitter.

Is ARTIS an Ethereum Blockchain fork?

No, but ARTIS shares the same code base with Ethereum: We are building on the achievements of a large and established community instead of re-developing everything from scratch. It will be easy for developers who already know Ethereum to develop for ARTIS.

What Consensus is ARTIS using?

ARTIS will be using a combination of PoS (Proof of Stake) and PoA (Proof of Authority), the so called "Honeybadger" consensus mechanism.

What happens when Ethereum launches updates?

As a Plasmachain network, ARTIS is closely connected to Ethereum. Updates on Ethereum are therefore constantly watched and implemented in ARTIS (if compatible). Furthermore, developments and improvements are actively provided to the Ethereum ecosystem as open-source. As a Plasmachain network, ARTIS is closely connected to Ethereum.

What programming language is required to write DApps for ARTIS?

Every EVM compatible smart contract language (e.g. Solidity) can be used for ARTIS.

What virtual machine does ARTIS use?

Our Virtual Machine will be the same as the one Ethereum is using - the EVM.

What transaction costs can be expected from ARTIS?

When applications use STREEMs, transactions will most likely be very inexpensive due to the low number of transactions and the direct implementation in the protocol. Transaction fees for discrete payments and one-time value transfers depend on the load on the Blockchain. Proposed future scaling suggestions like Sharding will come in handy to further scale the number of possible transactions per second and avoid raising transaction costs.

How can I join the ARTIS developer community?

If you are developer and want to get in touch, please use our developer channel Gitter to contact our team directly.

What is ATS?

ATS are the base coins of the ARTIS blockchain and are needed to use this public blockchain.

I came for the ICO / ITO, what happened?

The ICO / ITO that was planned for October 2018 was canceled in July. You can either read about our reasons for this decision or watch the announcement by our board.

What can I do with my ATS coins?

You can (directly as well as indirectly) pay for any service launched on top of the ARTIS Blockchain. ATS coins are also needed to pay transaction costs.

What about those other ATS-Coins/Tokens out there?

In 2017 and 2018 there has been an explosion of projects in the blockchain space. Many of these projects have since then been abandoned and are no longer active but have managed to be listed on popular sites like There are only so many three letter combinations around and so, naturally we have seen other projects using similar letters to describe their coins or tokens. This is the reason why you will find other projects listed as ATS. Needless to say, ARTIS are not affiliated with any of these projects.

If money is streemed, how does the real-world accounting, which needs a specific amount and date, work?

Accounting in the real-world is typically a period-based activity, e.g. monthly. In systems working with Streems, the total amount payed during a specific time period will be used for accounting. This specific amount would have to be stored in the accounting software.
