FAQ

Devvio FAQ

Devvio’s vision is to create the world’s infrastructure for transferring value. Devvio has created the world’s fastest blockchain as well as the only solution that addresses all of blockchain’s biggest challenges such as scalability, cost, stability, fraud/theft/loss and privacy, in a single solution. The following Frequently Asked Questions (FAQ) lists many common questions we have gotten, along with the answers. A good place to ask any additional questions is at Devvio’s Telegram group located here. Most of these questions have come from the Telegram group.

 

GENERAL

What is Devv and what problems is Devv addressing?

Devv is both a blockchain protocol and a cryptocurrency created by Devvio, Inc.

Devv is primarily addressing scalability, cost, stability, fraud/theft/loss, and privacy. When we first started looking into blockchain, there were no solutions that addressed all of these problems in a single solution, so we designed our own protocol from scratch. If one builds a house without a solid foundation, nothing good will come of it. Devv is unique in our sharding solution (we have recently benchmarked at over 8 million transactions per second), our privacy solution which is meant to work within government regulation, our fraud/theft/loss protection capabilities, our efficient and inexpensive Smart Contract solution (using Smart Coins), and our stable coin implementation.

The Devv cryptocurrency can be used for payment in Devvio’s Blockchain-as-a-Service business.

Which markets does Devvio intend to target?

Devvio wants to build the world’s infrastructure for transferring value. We large scale corporate use. We intend to create one of the most powerful blockchain solutions, and let many other people implement their blockchain needs on our platform, growing our Blockchain-as-a-Service (BaaS) business. We have the ability to create inexpensive, scalable, and secure Smart Contracts which also leverage our other protocol features (fraud/theft/loss protections, privacy, etc.). There are some vertical markets we would like to focus on ourselves as well, such as financial transactions (remittance, exchange, and payments).

 

I am interested in using Devv for my business. How much will it cost me to implement my business on the Devv blockchain?

Our cost for transaction fees we expect will be on the order of 1/100,000th the cost of Ethereum. That means that transactions that cost $100,000 on the Ethereum network will cost $1 on the Devv network. Our transactions are very efficient compared to other blockchain solutions. We will have a Blockchain-as-a-Service or BaaS, model where we then allow others to use our blockchain with reasonable pricing, similar in nature to cloud computing. Customers will have reasonable monthly costs without large spikes, as well as the ability to scale as your application successfully grows. Companies pay us directly to host their blockchain solution and digital assets (as opposed to Ethereum, for example, which uses Gas on-chain). Our approach is much less expensive, much more efficient, and lets companies have more stable and scalable payments month to month.

 

Can you illustrate 3 main use cases for Devv?

The Devv cryptocurrency is intended as a general purpose cryptocurrency as well as the currency we will accept for our BaaS business. Purchases of Devv can be in essence pre-purchases of Devv blockchain utilization. The Devv cryptocurrency has advantages over other cryptocurrencies. It has fraud/theft/loss protections, privacy that will work within regulatory environments, and scalability to millions of transactions/second. Devv also will be used on our BaaS business — customers can pay for their token usage in Devv. Devv’s Whitepaper lists a number of use cases (in the Use Cases section) for both the cryptocurrency and the blockchain.

 

Who do you see as Devvio’s competitors?

Ripple, EOS, and Hashgraph have similar technologies and could be competitors with us.

One thing to keep in mind is that the entire blockchain space is in its infancy. In 1999 many people were dismissive of Google. Blockchain is a fast moving and quickly changing space. The landscape in a couple years will be dramatically different than it is now and our goal is to be a leader in the space. We feel one of the main reasons that we can become a significant company and technology in the space is that we address the issues that larger institutions and enterprises want to see to fully embrace blockchain. We solve the problems that large entities need to have solved to use blockchain broadly. We envision we will be seen as “THE Enterprise and Institutional blockchain solution”.

 

Do you have any patents?

Yes, IP was a core focus for us from the beginning. We believe we will own some significant blocking patents for some important concepts in the space. Our team has a great deal of expertise in Intellectual Property. The first thing we did for Devvio when we were starting the effort was patent all our ideas before we told anyone anything about what we’re doing. That’s part of the reason we’re so far along but still under the radar.

 

Do you have industry investors who have shown interest, and where are you with securing these partnerships?

Yes, we have a large list of industry partners we’ve spoken to, and there appears to be a lot of interest in our solution. Our team has a lot of experience in corporate development, and our solution solves many of the biggest problems enterprise customers are struggling with.

 

How is it possible you are so far ahead of what other teams in the space have done? Seems this might be too good to be true?

We understand this question as we have often received this feedback. On the same note, we have wondered why no one else has addressed many of the problems we have solutions to as well. For example, it is surprising that everyone just accepts that massive thefts exist in the cryptocurrency space. There are five things we do that are particularly compelling — scalability, efficiency (and therefore cost reduction), fraud/theft/loss protections, privacy, and stability. We would argue that a solution that has all of those components in a single solution can truly bring blockchain to mainstream use. Our scalability (and the resulting efficiency) has been vetted and tested, and is described in detail in our Greenpaper. We have proven in a working system that it works, and additional experts in consensus algorithms who have done due diligence for potential investors have also confirmed our analysis. We have a video showing our benchmarking, our testnet is available, and our source code has been released, so anyone can do their due diligence on our system. The stability solution (which we call DevvFiat – it is not the Devv cryptocurrency itself) is a flavor of a stablecoin, but that concept has been shown to work. Our fraud/theft/loss solution and privacy solution are both clever, but they’re not really that complicated. If one does their due diligence, and really looks at all 5 components, one can see what we’re truly doing, and why what we’re doing will work. It’s only a matter of time until people realize the power of what we’re doing.

 

What is your business plan to drive adoption?

We are starting conversations with many enterprise customers. Our solution provides many of the capabilities and features enterprise and institutional investors need to see to truly embrace blockchain. We believe we could be THE enterprise blockchain solution. We are also planning an investment fund for our platform and have a great deal of in house expertise in planning that.

 

What is DEVV LTD, a Cayman Island exempt company?

DEVV LTD is a Corporation based in Cayman that is wholly owned by Devvio Inc. We are implementing our token sale out of Cayman. Many of the bigger token sales have been done out of Cayman.

 

Devvio seems to be under the radar at present - the best project you've never heard of. Have you already taken steps towards marketing Devvio on a larger scale?

That is true that we have been under the radar so far. We are making strong progress on the technical foundation, and feel we will not be under the radar much longer as we ramp up our marketing efforts.

 

What does the name, Devv, stand for?

Devv is short for Developer. By naming our cryptocurrency and protocol Devv, it references what it really is (software) and also is a nod to the folks who make it happen (Developers). The reason that is important, is it grounds the philosophy of what we're doing. Devv is a blockchain for mass use and for everyday people. The ultimate goal is to create the world's infrastructure for transferring value. That is an ambitious goal, but if we are successful on that large of ambition, we also need to keep in mind the roots of where we came from, and stay grounded. We like the idea of the folks who create something getting credit and upside rather than big organizations.

 

What does Devvio's Logo Represent?

  • The logo overall represents strength, indicative of us as a platform and foundation for the world's transactions (that is ultimately why we decided against some other candidates).
  • We felt that it looked pleasing at first glance. It was a favorite design from early comps, and then it continued to grow on us over time, as we realized more depth to it.
  • We liked the concept of using the various angles and corners that are in the logo (i.e. the 30, 60, 90 degree angles) for our overall brand, images, and website.
  • The logo is largely black and white. The black in contrast to white, implies unwavering trust. Blockchains are immutable. Immutable trust is black and white.
  • The diamond makes a compass-looking piece. Compasses are a strong icon for trust.
  • The logo consists of pieces that are reminiscent of / consist of blocks, which is important given the foundation for our technology is blockchain.
  • There are a number of Vs in the logo, which is also important in our branding. The triangles in the diamond make two Vs. The main piece is reminiscent of both a V and a D. One can see a V in the white space. The two Vs in Devvio are indicative of our brand.
  • The two triangles in the diamond imply transactions, transfer, and I/O - they are like arrows pointing in different directions.
  • We liked how one's eye can shift between different views with our logo, playing with the white space. It feels artistic to use. One can see the two pieces standing next to each other, upright on a plane. In that interpretation, one can imagine that the lighter part of the diamond is a reflection. Alternatively the large piece can then become a foundation that a small white house (with a pyramid roof) sits on. The 'M' figure between the two pieces is a pretty design in our view. The hexagonal shape surrounding the entire image is a pretty design in our view as well. One's eye can easily shift between all of those views.
  • The angle for the line separating the triangles on the diamond lines up with the line creating the symmetry on the larger piece. The bottom left corner of the D in the word 'Devvio' lines up with that same symmetry line (which is the back corner in a 3D rendering). The horizontal distance from the D to the larger piece is also the horizontal distance between the diamond and larger piece, creating some more play with white space.
  • The dot in the 'i' in Devvio is the diamond compass piece.

 

It would be useful to have a comparison table of Devv versus other approaches, so that less technical people can see Devv’s advantages?

In the Devv Whitepaper, we have a simple high level table comparing Devv to the majority of other approaches. In the Devv Bluepaper, in Appendix B, is a more detailed comparison between Devv, Bitcoin, Ethereum, and Ripple.

 

I have seen Whitepapers before. Are green and blue papers now the new norm?

Perhaps if we are very successful it will be a sort of new norm, but it is an approach we just thought out. Ethereum had some different colored papers to show different purposes. Some of our team’s background has an emphasis in graphics, so the Whitepaper is a summary, and we have more detail in our component papers, the Bluepaper (business integration), Greenpaper (technical implementation, and green because we solve the energy problems of Proof of Work), and an upcoming Redpaper (smart contract approach). Red+Green+Blue components = White.

 

TOKEN SALE

We do not have any specifics to report on a token sale, but we will post on our Telegram group when we do. Here are some answers to related questions though.

 

Can you tell us about the tokenomics?

Our hardcap is $18m, our softcap is $3m. We will sell 30% of Devv. The current whitepaper has some additional tokenomics details.

 

In the new Whitepaper you say that you will use 15% of the TGE proceeds for TGE fees. Why do you need that percentage for fees?

The fees percentage (in contrast to the other categories that were more based on amounts rather than percentages), is based on agreements we needed to put in place early on when we were first getting started. The earliest partners, who took risk with us up to a year ago, negotiated to receive a part of the token sale.  A large portion of it goes to early partners who helped to arrange the token sale in the first place, a large portion goes towards building the initial blockchain prototype that benchmarked at 1 million transactions per second, and a large portion goes towards IP acquisition. We’ve made pretty tremendous progress with the resources we’ve had, but much of that was in trade for future upside (that at the time had significantly more risk than we have now).

 

When will the TGE be held? Do you plan to issue an ERC20 token and then swap it with your native token?

We don’t have an exact date for the TGE. Yes the TGE will be ERC-20 tokens, and yes, there will be a swap with the native token in the future. We will do so because we are a protocol, of course.

 

Will Devvio provide incentives to hold tokens, such as staking?

We aren’t planning on implementing staking. I think there is a natural incentive for people to hold tokens given the progress we expect we’ll make, announcements we’ll hope to be able to make, and the future use of Devv in our BaaS model, which could be very valuable for everyone involved.

 

Where will value be created in this project?

We feel our entire effort will be very valuable. Devv will be used in our blockchain as a service business, and our BaaS business is built on a truly exceptional technology and team. We feel we have the best technology and approach in the entire blockchain space. We have the fastest blockchain in the world, and we have the only blockchain that has solved all of the biggest problems in blockchain in a single solution — scalability, privacy, fraud/theft/loss, cost, and stability. Imagine what that means towards taking blockchain to mainstream, and imagine the potential value our entire solution can hold to the industry, and the world. Our team are experienced businesspeople, and across the board, everyone who has gotten involved with us early on feels this is the most exciting thing they have not only worked on, but have ever seen!

 

TECHNOLOGY

A more detailed description of Devv’s technological implementation is given in the Devv Greenpaper, which can be viewed here.

 

How many transactions per second can Devv handle? How can you prove your throughput?

Devv’s latest benchmarking was at 8 million transactions per second, on-chain. You can see details on the test including a video in a recent blog post.

For those who feel the combination of a full description of our approach in the Devv Greenpaper plus the video is not enough proof, we also have a testnet available along with source code in a Github repository.

 

How is consensus implemented?

Devv uses Proof-of-Validation for our consensus mechanism, where validators (which are our consensus providers) create blocks comprised of transactions, and then collectively validate each block by sending validation messages. Our scaling is implemented with a multi-tier architecture which is a sharding solution. Proof of Validation and our sharing approach is described in detail in the Devv Greenpaper.

 

You claim 8 mil TPS have been tested? Was the test run in an internal network? How do you expect to reach the same TPS in a distributed worldwide network?

Yes, we have benchmarked the Devv blockchain at 8 million transactions per second, on-chain. The details of our tests, including a video, can be seen here.

There was low latency in the network, but that is realistic in our approach given our sharding solution. One of the advantages of our sharding approach is that the shards are independent blockchains, each running their own consensus process. In real life, we can have Validators close to each other in our shards (particularly the T1 shard), so low latency is realistic for consensus in our shards. Communications between T2 shards and the T1 shard can have larger delays but the cost there is some additional time between payment and settlement. We can use a concept of repeater nodes to maintain throughput as well. There are also other ways we’ve designed to further account for latency issues and other real world issues.

 

Will you be able to replicate the TPS testing in the Testnet having nodes in different locations/networks?

Yes, our sharding approach is designed for high throughput across a global network. Verification of a transaction can happen very quickly in a geographically localized shard, and settlement across shards can have some additional delay (a few seconds), but once a transaction is verified, settlement is guaranteed. We separate payment and settlement in our sharding approach.

 

Were you able to achieve the impressive throughput numbers because of lab conditions, i.e. everything was in memory and no real distributed systems communicated over a network?

This is definitely not the case. We wouldn’t have announced our results as we did, if that were the case (that would have been horribly misleading if that were the nature of the tests). Our tests use ZMQ for the networking communications. A single shard can process over 3000 transactions per second. If we simply kept all of the processing in memory, then a single shard itself could process millions of tps alone. Instead, we relied on thousands of shards to implement our benchmarking. We preprocessed the blocks for the shards as that is a fair way to benchmark a system like ours (since each blockchain is an independent blockchain). From the T1’s perspective the data it receives is not affected by preprocessing, and the results from that preprocessing were sent to the T1 network over ZMQ. The network we used had low latency (as it is benchmarking, so an ideal situation) but it represents real world use. We might take a relatively small percentage hit for real world use, which is the nature of benchmarking, but there are other optimizations we can add in too compared to our current system. Therefore we feel the overall throughput long term, even in real world use, will actually go up from where we currently are benchmarking.

 

How many TPS can you achieve inside a single shard?

About 3500 right now.

 

You say that there will be 'dozens of nodes' in a shard - What is a minimum & maximum number? Are there any technical limitations?

The number of nodes per shard will be defined by security requirements (as opposed to technical limitations) that we will determine as we do our 6 month security testing and audit. The primary question is how many nodes are needed to assure the prevention of 51% of nodes being compromised.

 

Can a network node be part of more than one shard?

A Validator node cannot validate for more than one shard. A network node can contain more than one Validator.

 

Do you plan to do a 'real life' test, with geographically distributed nodes?

Yes we will continue to expand our testing across many different scenarios and attacks, but that said, our test was indicative of a real world network as was described above. All of the actual communications that ran through the benchmarking were communicated through ZMQ. Delays in communication from T2 to T1 affect settlement time but ultimately not throughput. T2 Validator nodes will likely be geographically located near each other to reduce latency on Proof-of-Validation consensus.

 

When two wallets want to make a transaction, the chance that they are in the same shard will be minimal. How do you deal with this?

In general, one of the advantages of our approach is that shards can be implemented to focus on geographic areas or specific application areas (e.g. shards focused on IoT). Given that, many transactions will reside within a single shard. That said, we designed the system to have the same scalability even if all transactions go from one shard to another. We separate payment and settlement, so a sending wallet’s shard validates the transaction. Then that shard's block is sent to the T1 network, and it is put into a T1 block. Then the recipient’s shard reads the T1 block and validates the receipt side of the transaction, putting it in its block. A detailed set of diagrams in the Greenpaper Appendix A show the flow of a transaction through the entire system.

 

How many Developers are currently working on the project & what’s the plan to onboard or attract more in the near future?

About 6–8 developers have been working at various times and hours/week. We’ll have a bug bounty program, and expect to start ramping up getting many more people involved in general. One way we’re looking at doing so is with partners who want to use our blockchain — We’re onboarding developers from potential partners now.

 

What measures are you implementing to prevent attacks on Devv, especially potential 51% attacks?

The Devv blockchain is Byzantine Fault Tolerant up to 51%. We do not technically have the same kind of 51% attack that Bitcoin has - i.e. Devv does not have the concept of uncle blocks or uncle chains. Once a block is one deep in our chain, it is immutable and no uncle chains can replace blocks that Validators already added. On any given shard in our scaling solution, if 51% of the validators are attack nodes, then that shard can be compromised. Our T1 network, which handles cross-shard transactions, can determine inconsistencies. Hence, we can detect foul play before settlement. However, our goal is to ensure each shard not be able to be compromised, which is what a decentralized blockchain is good at. To prevent a 51% attack, we can add more nodes per shard. In addition, denial of service (DoS) type attacks are accounted for in our algorithms, and more nodes can be more robust there as well. A robust security testing phase is being done where we are implementing security testing. We will evaluate many other attack vectors in more detail.

 

How does Devv compare with the Lightning Network?

We feel Devv would actually be a good replacement for the lightning network. Users will be able to transfer Bitcoin to Devvio, and Devvio will put it in escrow and give the user DevvBitcoin. The DevvBitcoin can then be traded instantly, worldwide, with small to no fees (i.e. a one-to-one backed version of Bitcoin), which is the point of the lightning network. We feel this is a better way of handling the problem of scaling Bitcoin transactions. Anyone who has DevvBitcoin can exchange it for the Bitcoin held in escrow. The concept works with fiat (which we call DevvFiat), ETH, gold, commodities, etc. One of the biggest benefits of this approach is that the Devv implementation of any of these assets can utilize other features of our protocol like the fraud/theft/loss protection or our privacy solution.

 

Devv Operations

The following questions relate to how Devvio will run the Devv blockchain. Additional details are given in the Devv Bluepaper.

 

Is Devv really decentralized?

The Devv blockchain’s shards are independent blockchains, each with many Validators per shard. At the point where we are processing millions of transactions per second, we will have thousands of shards and each shard will have many Validators. The Devv blockchain’s operations are therefore decentralized. That is different than the permissioning of Validators.

Here is a summary of our position and analysis of the difference between decentralized operations and decentralized governance.

https://medium.com/@tomlucient/the-biggest-misconception-in-blockchain-6ac992ac79e9

We feel there is a general misconception of what miners do in the blockchain space. They simply order valid transactions. That’s it. The protections that one gets, and the trustless nature of blockchains, comes from the immutability of blockchain combined with the transparency of a public chain. Any two people can independently verify their transaction. Anyone can independently audit the entire chain. Devvio doesn’t oversee any transactions like a central authority does — Devvio simply oversees the Validators that order transactions. The reason, then, to permission Validators is to prevent collusion.

It is a very difficult problem to prevent collusion when anyone can contribute to consensus. Bitcoin has a reasonable approach, but there are many trade-offs (i.e. with Proof of Work) and there are many inefficiencies in that approach. When one adds Smart Contracts, the inefficiencies are much more pronounced.

Devvio intends to grow the Devv blockchain towards a permissionless system over time. We would argue that Devvio’s approach is the best approach, even if the ultimate goal is a permissionless system. If one wants to have a permissionless system in the end (in our case we envision Validators being comprised of universities and businesses where collusion would be so easy to detect and the risk of collusion therefore is so small, it is non-existent), we feel the best approach is to gradually work towards permissionless consensus while gaining experience along the way to implement it effectively. In the beginning, when regulations, technology, and competition are quickly changing, a lack of effective governance is a fatal flaw. In our approach, we will be able to govern our growth in the short term, and have years of operations under our belt as we tackle moving towards a permissionless system, arguably the most difficult challenge in the blockchain space.

 

Every blockchain (for example Bitcoin, Ethereum or EOS) has its own limitations. What is the major limitation for Devv?

Most decisions in blockchain design are trade-offs. In the blockchain space, it is often cited that one has to choose only two of scalability, security, and decentralization (known as the blockchain trilemma). That is not the case for Devv - our solution solves all three of those problems in a single solution. There is a difference between decentralization in operations and decentralization in governance. Moreover, there is a difference in trustless computing and decentralized governance. For example, when a blockchain is both 1) public, and 2) immutable (as ours is) you have the protections you need. Per the original Bitcoin whitepaper, anyone can transact without using a central authority and independently verify a transaction because it is public and immutable. That is where the real protections that are needed, come from. Given that understanding, we would say the main trade-off with our approach, then, is that we technically have the ability for censorship. That said, Devvio will not implement censorship, and will implement technical solutions that prevents it. Also, we envision the Devv blockchain will ultimately become an entirely permissionless blockchain.

 

Am I correct that there are no rewards for mining in the Devv network? If so, why would an organization choose to be a Validator?

Validators simply receive payment on par for running a server. Payment should be fair with a reasonable and fair amount of profit. We have a different philosophy than many other blockchains — the idea that people that provide consensus (which is fundamentally simply ordering valid transactions) would get millions of dollars of crypto per day doesn’t make any sense to us. Devvio’s approach pays validators fairly for their resources, but it is on par with any cloud service. Many validators will want to be part of the system as they will want to have interactions to assure their business requirements on chain (which is one area where we have already seen interest). Devvio will arrange for many other validators directly and simply pay a fair use for server usage.

 

How can people run validator nodes?

In Devvio’s approach, we decide on Validators and permission them to use our system.

 

Once the Devv blockchain becomes permissioness, what level of TPS can it achieve?

The permissioning won't dramatically affect the TPS. Sharding is where we get our scaling and it works with or without permissioning. The permissioning is needed early on to prevent collusion.

 

Devvio’s Business Integration

A more detailed description of Devvio’s business integration with the Devv blockchain is given in the Devv Bluepaper, which can be viewed here.

 

Will Devvio allow for the tokenization of private assets?

A large focus for Devvio is on our Blockchain-as-a-Service business. We will allow customers to tokenize assets for their business models. Customers will be able to implement their blockchain business on our platform in an inexpensive and scalable way, with access to the advanced features of our approach like fraud/theft/loss prevention and privacy.

 

Privacy Solution

Devvio’s privacy solution is described in the Devv Bluepaper.

 

How is your privacy solution different from those implemented by Monero, ZCash, etc? Aren’t you afraid you will be targeted by governments because of privacy issues like KYC and AML?

Our privacy solution was designed to be compliant with government regulation. We can provide true privacy, but we can also provide court ordered transparency. In fact, we describe our privacy solution as “True privacy, other than court ordered transparency”. We feel this is the only type of privacy that will be acceptable to governments, and therefore the only type of privacy that will be able to thrive. As brilliant as approaches like zk Snarks and other zero knowledge proofs are, in the end governments won’t like them because they provide true privacy. Governments want to prevent illegal activities like money laundering and terrorism.

In our approach, we can prevent people from reverse engineering identities in pseudonymous wallets, but the ways that we do so are tracked by a trust based entity (Devvio), which can then provide court ordered transparency of how private transactions were implemented. Devvio’s privacy service is an optional feature and Devvio is not a trusted authority in approving blockchain transactions.

 

Fraud, Theft, and Loss Protections

Devvio implements its fraud, theft, and loss solutions with an escrow-like functionality called DevvProtect. You can read more about DevvProtect in the Devv Bluepaper.

 

How customizable is Devvio’s anti-fraud solution for users? Will all users have the same settings or can settings be decided by each user?

Devvio’s fraud/theft/loss solution (which we refer to as DevvProtect) will be customizable. Users can have different wallets with different escrow time periods to prevent theft. On an individual transaction, one can set the escrow time period. A good use case would be to have a wallet with a long term escrow period, a wallet with a medium term escrow period, a wallet with a short term escrow period, and a wallet with a smaller balance and no DevvProtect protection for everyday use.

 

The Blue Paper describes that if I can prove my private key was stolen, the transaction can be reversed. What burden of proof is on the wallet holder. Can you elaborate on this?

Each of fraud, theft, and loss protections has different logic. In the case of a stolen private key, and subsequently stolen assets, if the user’s stolen funds were in a DevvProtected wallet, then the funds automatically go into escrow. If the user discovers the theft before the escrow time period is up, then Devvio can verify the user’s ID with standard concepts like two factor authentication, or other services in today’s world, in order to return stolen funds. After Devvio verifies one’s identity, it can create a transaction that effectively reverses the theft (technically it is a separate transaction moving the funds out of escrow, since the blockchain is immutable). If there is ever a question on ID or tight timing, Devvio can extend the escrow time. Keep in mind Devvio cannot initiate a transaction. It can only return funds that are in escrow (and will only do so under a user’s directions). DevvProtect is optional, and anyone who doesn’t want to use it does not have to.

 

What if, despite of all implemented safety and security measures, funds are lost. What is or will be Devvio’s legal liability?

It’s hard to quantify in a broad statement of course, but we will point out a few related concepts in analyzing that concept. The Devv blockchain is a regular blockchain like others — it is immutable, public, pseudonymous, transactions are protected by public/private keypairs, etc. Devvio’s DevvProtections are just a service that can help prevent fraud/theft/loss. All of the features for protection from fraud/theft/loss and privacy are optional. People will need to keep their private keys safe (same as other blockchains, and same as bank account information).

 

Do I need to create a new DevvProtect wallet for every transaction I want to protect, and do I need a new set of keys each time?

No, you can send a transaction as DevvProtect (escrow) at any point from a wallet that has been verified by Devvio. You can also create wallets that have a more permanent level of escrow on them (a DevvProtected wallet is needed for theft protection, for example).

 

Does a user need to pay to use DevvProtect?

We have not finalized the business model around Devvio’s services. However, we can give a feel on what we’re envisioning. We expect that in many situations users will not need to pay for services. We believe a model similar to credit cards will work well, where sellers get extra benefits by accepting Devv or DevvFiat and customers don’t pay for those features. In the case of a user who wants protections for a craigslist payment, for example, there might be a fee in that kind of situation.

 

Let’s say, someone stole my private key and my DevvProtect wallet is set at the default of 15 days. Is there a mechanism that will alert me to a possible transaction?

Yes, the plan is to let people set up alerts on any transactions if they have a DevvProtect wallet. That’s a big part of the point — DevvProtect gives people time to detect fraud/theft/loss but at some point the escrow releases and there is no further way to get funds back.

 

What prevents a hacker from changing the time period?

When a wallet itself is a DevvProtect wallet, one cannot change the escrow time. If you keep some or all of your funds in a wallet that protects them then you make the entire wallet a DevvProtect wallet and anything coming out of the wallet goes into escrow defined by the wallet’s settings.

 

Smart Coins

Devvio’s smart coin approach is described in more detail in the Devv Bluepaper.

 

As I see it, one can compare Smart Coins to Smart Contracts. Is it possible for external developers to deploy Smart Coins?

Yes! We think our Smart Coin approach is going to blow people’s minds (like Ethereum did when it was introduced). We are going to release a new Redpaper detailing our Smart Coin approach soon. We feel it is an introduction to a new blockchain philosophy that is based on an ultra efficient transactions and security at scale. Blockchains are good at two things, robustness and trustlessness. The implication there is that blockchain should primarily be used for maintaining assets and as much processing as can be made to be off-chain, should be handled off-chain. Also, a Smart Contract system needs to be secure at scale. BaaS customers will be able to use a compositional programming approach to combine Smart Coin functionalities through a DAG to get the capabilities they need. Smart Coins on T2’s will interact with third party implementations through Oracles. Only T2’s interact with the T1.

 

Why did you choose to not have Turing complete smart contracts? Will this decision hinder the capability of constructing complex smart contracts?

On-chain Turing complete smart contracts are a mistake in our view. Our smart contract approach is Turing complete, but it is designed with reasonable constraints that assure scalability and security. An on-chain Turing complete solution isn’t scalable, isn't secure at scale, and iscomplicated to implement. Our approach is dramatically less expensive, much safer and much more secure, will be easy to implement, and is scalable. Our Smart Coins themselves are built on C++ (Turing complete) so there are no limitations on what we can implement with our approach.

 

What programming languages can be used to compose Smart Coins into Directed Acyclic Graphs (DAGs) ?

Right now we’re using C++. We’ll support other languages over time too.
