Best Choice for Blockchain Development

Diana Rayan
posted on 18/10/18
We had long been dealing with the issue of achieving more transparency in our business. Hence, we reached out to Errna for building a private blockchain solution exclusive to our organization that would enable us to have better transparency as well as control over different business processes. Our collaboration with Errna was a great success as now our business is efficiently supported by a custom private blockchain. The project turned out to be quite affordable with their sincere efforts. We’ve been getting great results after the implementation of this solution by Errna. I would highly recommend Errna for blockchain related development services.

What is it about the company that you appreciate the most?

Errna team was very responsible and cooperative in handling our requirements and occasional requests for changes which made the entire experience positive for us.

What was it about the company that you didn't like which they should do better?

Overall I was content with their services, so got no suggestions for improvement.

Victor Austen
posted on 21/10/18
We were searching for experts in blockchain technology to build us a decentralized tracking platform for our online advertising campaigns, and experts from Errna did a great job for us. They developed a perfect decentralized blockchain system application for us to keep track of our campaigns, the app was supported on iOS and Android platforms. Moreover, their ICO development and marketing team was just so excellent to frame the whitepapers and smart contracts (ERC-20) from scratch. I would for certain recommend their blockchain development services to others.

What is it about the company that you appreciate the most?

The experts at Errna were professional and were highly dedicated to their work. They completed the tasks on time and kept us informed with their daily updates and reports. It was an overall great experience.

What was it about the company that you didn't like which they should do better?

My project was delivered to me in time and without an error. So, no suggestions for this field.

  • We consider giving the best possible solution to our customers, and we leave no stone unturned in ensuring that they receive the ideal blockchain experience.
What industries do you generally cater to? Are your customers repetitive? If yes, what ratio of clients has been repetitive to you?
You may find the implementation of a blockchain-based application in industries as
varied as supply chain management, fashion, and publishing. There's innate
flexibility of blockchain to be leveraged in any industry. The characteristics of the
blockchain platform can be processed to suit a variety of needs. The earlier an
investor understands this, the sooner they will perceive how exactly it might be
applied to diverse industries, proffering them a degree of certainty, which can help
them measure the potential of a project to disrupt an industry.
 
Blockchain technology holds the endless potential to dramatically disrupt a broad
spectrum of industries beyond transfer and the storage of value. Cryptocurrencies
might be the most obvious use of this blockchain, but the nature of the dispersed
ledger technology introduces a multitude of practical usage cases such as real estate, healthcare, music, credit, insurance, blockchain as a service, digital advertising, energy, and many more.
 
With our impeccable team and satisfactory service, Yes, we do observe the situation of repetitive customers. The ratio of clients that bring repetitive business to us is 7/10.

  • Smart ticketing Solutions
  • Blockchain mining software development services
  • Blockchain supply chain management.
Which platform do you prefer to use when developing a blockchain application? Why?
We work on a variety of platforms as per the client's needs and specifications.
Ethereum is one of the beneficial and public source Blockchain that also builds the foundation for the development of the other applications. It has multiple language applications like c++ and python.
  • Hyperledger Fabric is also an open-source blockchain platform for developing Blockchain technology-based applications. It provides decentralized hosting and decentralized storage of applications with smart contract ability.
  • Multichain Blockchain is amongst the ultimate choice to develop and deploy distributed ledger applications immediately. It is compatible with Bitcoin, and it is an open-source platform.
  • Ripple blockchain platform is enormously appreciated amongst the association of banks, payment providers, and corporates. It offers cross border payment solutions. This platform can be used for large size business institutions.
There are various other platforms that we employ, which include R3 Corda, IOTA,
Hydrachain, EOS, Steller, etc.
What tech stack and tools do your developers use?
At Errna, our team employs widely used and trusted tools for development purposes. The tech stack is a blend of software tools and programming languages that are applied to bring a blockchain-based web or mobile app to life. All the web and mobile apps contain Backend and frontend. The frontend is usually built using a combination of JavaScript, HTML, and CSS. The Backend is not visible to users and consists of a database, server app, and the server itself.
Are open-source, decentralized protocols going to be more significant than their web equivalent?
The open-source development model has demonstrated to be a thriving model that permits quicker development, more accelerated testing, greater innovation, peer review, openness, and transparency.
 
Decentralized, closed-source applications expect users to believe that the app is as decentralized as the core developers state it is, and that they don’t have access to their data through a central source.
What scalability and throughput challenges are there with blockchain? What solutions would you suggest?
The main scalability problems that hinder its operations and their solutions are
discussed below:
  • Response time: the time is taken to put up a transaction in the block; time is taken to reach consensus i.e., every purchase needs peer-to-peer verification; that is a very time-consuming process.
  • The Lightning Network is a payment protocol that is dependent on the SegWit platform, and it offers instant transactions.
  • The sharding Technique is used for verification of the blocking process and capable of running parallel subcommittees. This technique is able to handle 2400 transactions per second. 
  • Data size: As the transaction continue and record grows, block size increases ultimately surpassing any limit. The hard fork method is generally employed to reduce the data size. 
  • Limitations: The blockchain adds up one block each time a purchase is made, forming a ladder of blocks, and with an increase in blocks, the system is in danger of collapsing. 
  • Segregated witness (SegWit) is designed to solve transaction malleability but enhances the block size issue. It enlarges the block size limit to 4Mb.
  • Cost: The high traffic overloads the system, and miners prefer transactions with higher fees. Proof of stake, which uses the Casper consensus algorithm, is implemented, which uses validators instead of miners. Validators lock up some cryptocurrency as a stake, and if the validator places a bet and block gets appended, the validator will get a reward proportional to their stake.
Will the success rate of ICOs be better or worse than tech start-ups?
ICOs are a crowdfunding component utilized by tech startups. The failure rate of
ICOs is reasonably high, however identical to tech organizations using conventional financing techniques.

Now, the success rating of ICOs is superior to the success pace of the new tech
companies, and this is mostly because of the absence of guidelines empowering a
recurrence of scams and useless coin ventures.
 
Conclusively, it can be perceived that how the success pace of ICOs will tumble to be nearer to the actual success rate of startups, as the entire business gets more
intelligent.
What are the key factors that you consider before deciding the cost of a project?
The price of software development is not always clear cut. Since many business
owners understand the advantages of having a blockchain-based application
developed to their specific methods, they forget the facts that go into the design
process.
 
The time it takes to get the job done, complexity, or the extent of the undertaking, the number of team members there are, and where they dwell are a few of the elements that go in the cost of software development.
 
No two projects are going to be just like every other one as each company has
different requirements and expectations for their product and its development.
Additionally, various factors come into play because, as the project progresses, it may result in additional time and cost required for the software to work correctly.
What kind of payment structure do you follow to bill your clients?
Payment on milestone.
What is the price range (min and max) of the projects that you catered to in 2018?
$5000 and $1000000.
