I am Arthur Breitman. Ask me anything.

Arthur Breitman is one of the co-founders of Tezos, a blockchain platform which provides smart contracts, has built-in governance system, and facilitates formal verification. Unlike the majority of blockchain platforms, it uses the delegated proof of stake consensus.

Prior to Tezos, Arthur worked at X (previously known as Google X), the self-driving car division. He comes with great knowledge of technology, blockchain, and programming. Don't miss out the opportunity and ask the questions.

Ask Arthur Breitman about:

  • Tezos and blockchain governance
  • Developing Dapps in 2018
  • Proof of Stake and other consensus mechanisms
  • The future of Bitcoin
  • The current state of Blockchain
  • Blockchain development

How do you see the current and future status of UX design in the Tezos community and ecosystem? Do you see much interest and activity around design in the community? Thanks.

I think there's been a systematic under appreciation of UX in this industry, despite everyone paying lip service to its importance. I suppose UX is hard, and is often not in the realm of competency of the engineers behind those systems.

I think Ledger is a good example of a firm that's done very well by providing a much better UX around security than was available before.

Salut Arthur, j'ai trois questions pour toi :

-How Tezos is going to manage nodes in the futur, so as to keep the protocol as much decentralized as possible ?

-Did Tezos plan to create a structure like Consensys did for Ethereum, to promote the protocol and helps its integration in old companies (banks, insurers...) ?

-How many dapps are currently being developed ? Merci :)

1) It's an uphill battle as economic forces systematically push towards efficiency which generally means centralization. The main tools in the utility belt are : trying to give lower marginal operating costs to smaller entities (i.e. dis-economies of scale) and increasing risk for large operations.

2) Tezos is a blockchain, it cannot create structures.

3) I don't know. I've heard of maybe 5-10 but there are probably more. I'm not super into the "dapp" model.

On January there will be first voting on tezos for protocol upgrades. Is specs defined yet ? On which proposal we will vote ? At least do know them a bit would be nice. And there wasnt any testing for voting and still there is no documentation do you this is a vulnerability for January voting. Thanks. Keep up the good work. I believe tezos will be the biggest smart contract platform in this ecosystem in a couple years.

A blog post is coming to explain in details the voting schedule. When there are no proposals, the protocol keeps looping in a 8-cycle long "proposal" period (about 3 weeks).

There are on proposals at the moment, though I expect that one will emerge out of https://gitlab.com/tezos/tezos

Another question:

We have seen many blockchain influencers talking about Blockchain and Fintech, Blockchain and Health, etc. But no one talks about the type of companies that are not fit for blockchain.

Do you think every Internet company can be ported into blockchain? Which domains are you sure blockchain is not made for.

In most cases you can use a blockchain, it's just that it doesn't buy you a lot. I would also differentiate between public and private ledgers.

  • The benefits of a private ledger over a simple database is better data integrity and replication, it's not world-changing, but I do think it has some value.

  • The benefits of a public ledger is censorship resistance and Internet scale.

I would say domains which don't benefit from this type of scale or which don't require a high level of trust don't really gain from the use of blockchains. In general, anything that's not centered around tracking assets is not very likely to be a good fit.

Hey Arthur, Thanks for doing the AMA. I love Tezos. Here's my question:

What role do you think AI will play in Blockchain in the near future? Have you seen any project using this combination?

Arthur B.'s photo

I have a strong interest in AI and my background is in machine learning and statistics in the first place. That said, I think the intersection between AI and blockchains is very narrow.

In general, blockchains, contracts require hard, predictable, rules. Most modern AI isn't a great fit for that. Some people have also envisioned data markets for AI on the blockchain... I'm skeptical, why does this need to be decentralized or censorship resistant?

I think the intersection lies in tooling and analysis : AI learning to synthetize adversarial inputs to test the security of smart-contracts, AI learning profitable deviation from the honest strategy in a consensus algorithm, etc.
