Description To Throw in JP Morgan Juno developer, a Private Blockchain solution

JP Morgan, the two main developers worked for the bank’s own blockchain project Juno have started their own blockchain project.

Is Martino and Stuart Popejoy have again started to Kadena.io in June 2016. Is Martino was one of the chief-engineer of the Haskell office of JP Morganür the technologies of the group, and Stuart Popejoy built-in technology, modern equipment of the JP Morgan Emerging Technologies Group, focusing on solutions for the banking sector.

Kadena, the blockchain is by ScalableBFT to scale the first agreement of bluefin TUNA in the location, to thousands of nodes. The transition from the will, and Stuart made a great stir in the blockchain world.

Open source and large companies

Cointelegraph application.Martino about what you think the large companies the use of open-source technologies, if the key is for the developers out their own projects

Martin dit:

and for the artist;the decision Of the open-source Juno was good to present strategic decisions by JPM executed with the aim of the Hyper Ledger the Foundation as a candidate for the technology stack. The decision, JPM has brought in the implementation of the guide is important in its own blockchain space. RSüs, the new technologies, the group " open source efforts, which looks like a client competitive advantage, to attract attention and to engage, motivate and retain top-notch developer.”

The new star in the world of Finance

Private block chains, to the attention of a large number of banks and financial institutions. However, as long as these new technologies become a part of our life, every day is an interesting question.

Is Martino believes that these technologies are from the point of view of the consumer, as soon as the finances, the technology moves through the acceptance of the healing.

He thinks that she works as a direct treatment of the transfers would be an example of this type of technology, and have an impact on the everyday life of the people.

However, at the same time, the biggest beneficiaries are the large institutions, such as the cost of the infrastructure, reduce significantly, and that you will be able to the customer’s access to new technologies.

Kadena, the addresses of the main problems of the blockchain

It has been said that Kadena is the first blockchain address, the &other;the building on the issues– the block chains in a private environment. He said, Kadena, is not required, the basic guarantees must provide for a blockchain.

According to him, private blockchains fundamental problems for the failure of the miners— breathing. Unacceptable, the performance is also an important question.

You think that the performance problems are unavoidable, but the incentive, the ventilation can be interesting.

He said:

and for the artist;private miners, who are also participants blockchain. It is enough of an incentive in order to deny the potential for the company, an advantage of data mining on a fork? The legal consequences could the new negative incentives, but if we need a cut’s the participation of the mining industry in the private contexts of the function, we can really say that mining in this context, the works? Centralization, for example, in the case of the registration of transactions in a Central part 3, before data mining, is another possible solution, however, is that he rsquo;t are distributed, and asks the question “ why are we bothering with the mining, when we’re the centralization of all modes?”

While Conventional BFT consensus approaches can be used to build private blockchain solutions, have a tendency to pull too much, the scan of the model of safety.

He thinks that a possible solution is to abandon the public key for verification of signatures for TLS-based authentication, but this would only lost a fleeting impression of safety, from your point of view as the &additional;test— authentication, if the connection is closed. In their opinion, private block chains need to be sustainable security and every transaction and rsquo;s authorship should be verifiable and controllable by a media cryptographic.

Kadena, according to him, is the first credible alternative because it manages a high performance in the scale, while a sustainable security in the Bitcoin model offers.

Kadena’s the difference of Juno

The why and the how, such as Kadena and Juno different, that is an interesting question, and we were raised to will. He told us that Kadena is based on the belief that Tangaroa (Juno began as a fork of this project) showed the potential of advances in technology, the blockchain.

Cointegraph said that their work has helped in Juno, to inform, to share this opinion, but in the end, there is a lack of smart contract on the solution of problems and for the prevention of scale.

Speaking of Kadena, she said):

“ Our new blockchain, which is also known as Kadena, by ScalableBFT to scale the first agreement of bluefin TUNA in the location, to thousands of nodes. Up to now, BFT consensus protocols, such as PBFT and SmartBFT confronted with the fundamental problems which prevent the extension. ScalableBFT to &for the artists, raft+BFT” of the family of protocols in descending order of Tangaroa (Copeland/Zhang), the basic characteristics of innovations that enable forflat scale. We’re happy to announce that with ScalableBFT, Kadena, reached the first place in the industry: the Kadena blockchain and the rise of more than 7 000 operations per second and latency well below 100ms can handle, in the support of hundreds or even thousands of consensus between the nodes. This performance is all the more remarkable that sacrificed nothing of the cryptographic strength of the expectation of a blockchain, to show that the security in a sustainable way. Our consensus white paper has more details.”

Smart, In The Language Of The Treaty

Apart from that, there are other differences. Kadena characteristics of Pact, a new declarative Turing-smart incomplete language of the Treaty, while Juno was on the basis of the funnel to become, according to the will, always ready.

Talk of the need to have a smartphone in the language of the private contract, block chains, which could be suitable to the level of the company for the processing of transactions, and speak of Bitcoin, the Aether, and the Dao: 

and for the artists, Bitcoin contracts are limited to a variety of smart support-contract of use cases, the segmentation based on the solutions.leads

Up to the time of the Ethereumös power was for the artist, the only game in town,”, but it is a terrible option for the processing of transactions: to him, the key security features such as the database-style transaction, commit, and rollback; allows you to risky, Turing-complete calculations for General use within the blockchain, so that the solutions, such as the example of 50 m $DAO hack; it is prone to errors and are not verifiable development environment, the primitive, tools and opaque, is not readable, the byte-code, there is no possibility to verify the quality of the execution of code in the blockchain.”

The infrastructure of motor

The Kadena project, and the Federal government, the language of the contract is, therefore, Martino and Stuart Popejoy, such as &additional;the infrastructure-motors  the power of blockchain technology for the private use of the curve for adoption.

You think that to solve the private block chains, a series of questions, the processing of transactions, a lot of operations and engineering usually requires experience.

Speaking of blockchains in the future Martio said:

and for the artist, Surprisingly, the blockchain solves all these problems and focusing efforts on the solution of business permits issues by the encryption logic of the transaction, the in smart contracts. In fact, the highly praised support for the utility of cases as an inter-organization application, such as the payment of compensation is almost a &to the artists as a bonus” and, although it is tempting, and the exchange of game in its own right. Also in a smart way, in the language of the Treaty-such as the Bund, the development of lucid, the user promotes testable business logic, similar to the trust, are in a Bitcoin system is based on the use of a Pay-to-PubkeyHash or multisig contract. In the inter-organizational case, we can even see the normalization of the level of the logic that might be where the enormous acceleration of the company.”

I was not able to check the invalid address and amount, no alert shown. also not able to transfer the tokens.

I am working on a POA concept and was trying to send tokens from one account to another via a testing script, but was not able to, because I was not adding the god damn async call back function. Thank you so much for doing this video.

Amazing content, love how you don't just fly through the why's!
How can I get in touch with you? I have some questions I'd like to ask, I will pay for your time if that's the case :)
