HIGHLIGHTS ARE MARKED WITH BLUE STRIPES

Question(s):

On a technical level, one of my main questions, is: how will Overledger deal with the fact that the time to confirm an immutable block varies between blockchains? For example if a mApp written on Overledger writes to to the Bitcoin blockchain and then to the Ethereum blockchain, what happens if the Bitcoin block, containing the transaction, ends up being orphaned?

Answer(s):

Overledger makes use of a two-phase commit protocol when performing transactions across chains. For example, a transaction between Bitcoin and Ethereum would start by posting a signed “ready” message in each blockchain. Only when both blockchains contain these signed “ready” messages will the actual transfer occur. This is accomplished by posting a “commit” message on the blockchain where the transfer originally started, which includes a pointer to the hash of each “ready” message.

Question(s):

is there any public partnership use case, which can be presented in order to illustrate the technical capabilities ?

Answer(s):

Two Such Example could be…

Tracking goods across borders too; tracking the supply chain of agricultural products from farm to table.

Travel across borders with advance passenger information and pre-departure / Check-in. Gilbert has discussed this in an earlier AMA with Jason Grant @flexwebs

Question(s):

What do you see as your biggest weakness?

Answer(s):

One weakness is that the Quant Brand is relatively unknown. The team will embark on a global mission to spread the word about the Overledger. One of the first stops will be Gilbert’s visit to Washington USA in June which will afford major marketing opportunities, including planned TV appearance whilst stateside. In the fast-developing/changing blockchain space, being a new brand can be turned into an advantage, especially as the Overledger is unique and solves the interoperability problem in a different way to its closest competitors. The team will celebrate that difference. With the Support of community along the way. Finally, the team will have major announcements and partnerships as the project matures; watch this space!

Question(s):

Won’t storing all the information recorded in the ledger at any transaction a duplicate of the underlying blockchain? Doesn’t this affect the overledger size and scalability ?

Answer(s):

Compared to the ledgers that it interacts with, Overledger has to store a very small amount of data; in fact, the bulk of the information used in a Quant mApp (multi-chain application) is stored on the different blockchains (e.g. Ethereum) utilized in that mApp.. Overledger is simply a model and a protocol for communicating across blockchains; information storage is largely delegated to the blockchains that Overledger runs on top of.

Question(s):

More of a use case question but…. atomic swaps….are they essentially mApps and can therefore be developed with Overledger?

Answer(s):

Absolutely. Since Overledger uses two-phase commits for all transactions, a mApp could facilitate an atomic swap across multiple blockchains.

Question(s):

How does the security background from the CEO impacts or drives the developments and strategy ?

Answer(s):

Gilbert has over two decades of information technology experience under his belt with an emphasis on digital security. Boasting an MBA in Strategic Management, he has held top information security positions alongside notable employers such as Ernst & Young, the Bank of England, and the U.S. Federal Reserve System. This security expertise in the private and financial sectors is a central motivator behind Quant’s strategy and focus on digital asset protection, as well as enterprise-level cooperation and adoption.

Question(s):

Isn’t any conflict of interest between creating a company / blockchain dealing with interconnections, and being the lead of the ISO/TC 307Blockchain and distributed ledger technologies ?

Answer(s):

No 😉 All the work in ISO is open and collaborative, we are creating a technology that is ISO compatible. Like IBM!

Question(s):

How can Overledger restore the trust in the Internet, as you will have to cope with the underlying blockchains you will connect ?

Answer(s):

This is not for us to police! We are facilitating openness and resilience. We are giving people/community a choice, so how the community uses the Overledger and relevant blockchains it is up to them.

Question(s):

Do you plan on getting on some exchanges, and on which time frame ?

Answer(s):

As of right now, no official exchanges have been announced. However, more than 5 exchanges have approached us, and that list is growing. We will release further details when it is appropriate to do so.

Question(s):

How quickly can the network react to new blockchain projects rising to the top every day and who decides which blockchains will be “on-ramped”?

Answer(s):

Quant will be guided by a mixture of community & market demand.

Question(s):

How many QNT will be required for access to mApps and will the tokens be ‘used’ or simply read as an access token?
Also – will there be any other way to use/consume QNT? (aka how will token velocity be achieved)

Answer(s):

QNT required for access will be confirmed closer to launch date of the SDK. It is too early to determine the cost. We will have a flexible approach that will meet market demand.
The QNT token will ‘simply’ Read as an access token.
Developers, Enterprise and users will need all require QNT.

Question(s):

Will Quant be integrating with SWIFT at some point?

Answer(s):

Yes, this is very likely; but it will be driven by market demand.

Question(s):

Isn’t the metadata added to the blockchain size limited ? How do you manage to add blocks from an external blockchain ?

Answer(s):

There is detail in the Whitepaper.

Telegram Reference Msg: 45368

Question(s):

The proposed schema is comparable to the one used for VPNs (authentication by certificates, then a shared secret is used to communicate securely)…
Do you plan on using a key refreshing mechanism?
How can this be applied if the shared secret is used to prove messages reception ?
If not, doesn’t this weaken the certificate authentication, as it will use asymmetric encryption to communicate?

Answer(s):

For a comparison, we would closer to compare the Overledger to TCP/IP.

• Do you plan on using a key refreshing mechanism?
• How can this be applied if the shared secret is used to prove messages reception?
• If not, doesn’t this weaken the certificate authentication, as it will use asymmetric encryption to communicate?

For greater detail please see the whitepaper, What we can say at this moment, is that the ownership and management of the keys is driven by the user/customer.

Question(s):

Can Overledger be compared to the JVM ? or how does it differs from the JVM ? Do you plan on releasing for Windows, Mac and Linux at the same time ?

Answer(s):

It can be from a high-level point of view. We are solving a similar issue to that which JVM is solving from an application perspective.
JVM has limited usage compared to Overledger.
The SDK is for the different languages and not the operating system

Question(s):

What are some examples of use cases with Quant and what is the feasibility of mApps?

Answer(s):

In short, most decentralized applications nowadays rely on a single ledger, so any application that stands to benefit from avoiding single-ledger dependency is a potential use case for Quant. As Overledger’s mApps are programmed in a blockchain-agnostic manner, mApps can be migrated (in modular sections or entirely) seamlessly to other blockchains, while other single-ledger dependent Dapps would be left exposed to risks such as volatility, clogged network speeds, and high switching costs.
Furthermore, multi-chain interoperability will usher in a new wave of decentralized applications. One large category of these exciting new use cases is mApps that enable interaction between private and public blockchains.
For example, imagine a permissioned blockchain implemented by a national government for identity verification—let’s name it IDChain. Now imagine that you go to a concert, and find that the concert venue is using Stellar to process payments and Ethereum to keep track of all other relevant data, such as ticket sales and guest information. . Via a mApp built on Overledger, these three chains will be able to communicate seamlessly together: Identity verification will meet a state-approved standard via IDChain, payments will occur quickly on Stellar’s lightning fast blockchain, and sales/visitor data will be securely stored on Ethereum, all in one single user-friendly program.

Question(s):

In the whitepaper it states that “information needs to be routed from the source to the destination.” What is meant by this? Isn’t BC and DLT agnostic of routing since the nodes just send data to other nodes, but not in a directed way?

Answer(s):

This was a reference to other interoperability solutions, where a transaction from one blockchain must be routed through a system before it gets to the destination blockchain. Overledger overcomes this by directly reading messages embedded into each blockchain instead of handling any kind of information routing.

Question(s):

What is Quant definition of a PII in the context of its architecture ?

Answer(s):

Quant will not be handling personal identifiable Information, this will be down to the developer and how the developer uses Overledger. It Is not for us store PII. As stated in the White Paper the Overledger separates the messaging layer from the transactional layer.

Question(s):

The project itself is such a massive undertaking, there are at least 4-5 big projects within Quant itself… what is a rough timeline things will be ready by?

Answer(s):

Please see RoadMap; The Quant team will look to update the community regular intervals.

Telegram Reference Msg: 45369

Question(s):

In which coding language(s) are the mApps going to be written? does it depend on the underlying protocols?

Answer(s):

We will publish SDK’s in various languages. This will be driven by the community and the market, so the community can create their own mApp’s.

Telegram Reference Msg: 45369

Question(s):

Compared to other Ineroperability blockchains, how different is QNT in terms of developing mAppS? Will we need to learn a new programming language for this purpose or it will be platform independent?

Answer(s):

The idea behind Overledger is to simplify the process of developing Multi-chain applications. No new language required.

Telegram Reference Msg: 45369

Question(s):

Given the increasingly growing number of public platforms that are all sizeable, will there be SDK for platforms to integrate into your protocol? When do you expect the beta of the first two integration with BTC/ETH integration to complete? Are there any predecessor/ competitors you are looking at to compare?

Answer(s):

This will again be dependent on the demand from the community and the market. The potential to add/connect Overledger to other platforms is there and there will be integration points.

• When do you expect the beta of the first two integration with BTC/ETH integration to complete?

As set up RoadMap

• Are there any predecessor/ competitors you are looking at to compare?

We are tackling Interoperability in a different way. The example the team have used is that we were inspired by the best of both OSI and TCP/IP laying models, which laid the groundwork for the development of the internet

Question(s):

What is the next blockchain after BTCÐ?

Answer(s):

We would like this to come from the community and enterprise.
