How to Hire a Blockchain Developer
If you're not completely satisfied, you won't be billed. From there, we can either part ways, or we can provide you with another expert who may be a better fit and with whom we will begin a second, no-risk trial. Blockchain software is the hot topic right now. You know they should be able to tell which solutions to use in a specific business context. But it was complicated. If you needed a loaf of bread, but the baker required a new tool that you were not able to deliver, what then?
As economies grew, this approach quickly became extremely ineffective. Money changed everything, allowing us to extract the value of a product and put it into a material that is hard to produce but easy to exchange.
Now, you can buy a loaf of bread even if you do not have anything that a baker needs—you simply transfer value using currency. If you want to use money, you need to agree on the specific type or types of money that are accepted by enough people to run an economy efficiently.
And who had enough power to impose precisely one sort of money on many people? In the past, coinage was approved by a king or queen, who guaranteed that you could use the currency in the land they ruled—everyone was forced to accept it. Monarchies in many places transformed into other systems of government, and in the meantime, banks were born.
Still, this classical approach needs a central authority producing the means of payment. In the early s, Satoshi Nakamoto wanted to create a currency that could be signed without any central authority. One issue to solve was how to decide if a transaction happened and in which order it occured in the timeline. This problem, known as distributed consensus , cannot be solved in all cases.
But a digital currency is just one particular case, and Nakamoto was able to solve it. When we create a currency, we need to have a way to know who is the current owner of a coin and also the history of its movement. Banks have historically tracked such details using a ledger. Bitcoin is a digital, distributed ledger where everyone can verify all coin operations.
If we want to use such a distributed ledger, there are some issues to solve: Who can make an entry in this book? Supposing just anyone is allowed, how we can prevent someone from cheating by using the same coin for two different operations at the same time? This latter problem is called double spending and also is solved by bitcoin. To be accepted by the network, there are some conditions. Every transaction needs to be put into a block, and a node needs to use its computing power to solve a related mathematical puzzle, called its proof of work.
When a block is transmitted, each node that receives it can decide to append this block onto its most extended chain. This is the default behavior in bitcoin, which guarantees that we can achieve consensus. Then the node can start mining a new block linking to this latest addition as its previous block. We can say that a transaction is accepted when a specific number of nodes have added this block onto their chains.
Now that you have an overview of blockchain technology, here are some questions every blockchain application developer should be able to answer clearly in an interview. A blockchain is a distributed data structure, in the form of growing list of records—although it can also be represented as a tree—where every node is connected with another by cryptography. Block data contains all operations not yet included in another mined blocks. They have to have been accepted by a miner, verifying that the transactions do not break any conditions or rules of the network.
In most cases, there is an upper limit to the amount of data that can be included in a single block. Mining is the process of adding new blocks onto the blockchain in proof-of-work systems. What is the difference between permissionless and permissioned blockchains? In a permissionless blockchain, everyone can join and become the part of the consensus process. Any popular public blockchain can be seen as permissionless.
In a permissioned one, there is an additional authorization layer, which is used to control which nodes have access to which part of the blockchain; e. There are some solutions which can be seen as hybrid approaches.
For example, J. The genesis block is the first block of any blockchain. It is the only block which does not contain a hash referring to a previous block. In many practical solutions, this block is itself hardcoded in software. It is a difficult computer science problem without a general solution, having been solved only for specific use cases, like bitcoin.
A cryptocurrency is a digital asset that could be used as a replacement for existing fiat currencies. One of the goals of cryptocurrency technology is to eliminate the requirement of having a central authority which approves transactions.
The first widespread implementation was bitcoin, created by Nakamoto and launched in January Since then, many different applications have received publicity. Ethereum provided a solution to run smart contracts and launched in July This brought the concept of DApps—i. Morgan started or supported working on private networks, which can be run by any company and can be used to implement particular business requirements like an internal ledger of operations inside the company.
Their support gave rise to solutions like Hyperledger, R3 Corda, and Quorum, an enterprise-focused version of Ethereum started by J. These solutions can handle many use cases that cannot be supported by public networks. For example, they have much better transaction throughput, additional security layers, and specific consensus algorithms.
The proof-of-work system is one in which the sender of a message or the creator of a kind of transaction needs to perform hard work to sign the operation. They need to bear the cost, in an economic sense. But the process of verification of this work is easy and fast, so that everyone can do it in a very short period.
To send an email, the sender first needed to calculate the SHA1 hash from specific input data such that it would contain a particular number of zeros. The difficulty level was established such that a modern computer took about one second to complete the hash, but for spammers, who need to send thousands of messages at once, it would carry a very high economic cost, making the business of spamming unprofitable.
This approach is used in bitcoin for similar reasons. One main difference is in the target time for resolving the puzzle.
When you mine a bitcoin, it needs to consume enough resources to guarantee that a new block will be not created too fast—it could cause many orphan blocks, and more blocks have to be mined to confirm the transaction. Unlike with the original email context for hashcash, on average, a new bitcoin block is signed every ten minutes. If we add more power to the network, the puzzle needs to become harder. So the economic cost is growing. In practice, the level of difficulty is changed every blocks.
Why do we need to use public-key cryptography in a blockchain? Without encryption, every operation could be easily reassigned and then the network could be corrupted. A transaction is signed using the private key of a sender and contains the address of the receiver.
In bitcoin, for example, a public key is such an address. Then after broadcasting, everyone can verify the sender using their public key, which is available through the network. Smart contracts were created as a digital replacement for paper contracts i. The most popular implementation of smart contracts can be found in Ethereum. In the context of Ethereum, a smart contract is a simple computer program, existing at a specific address, that is executed whenever a transaction is sent to that address.
The code has to be run on every node of the network: All nodes need to reach consensus about state of the blockchain. Thus every program needs to return exactly the same result given the same input data and state. This is especially true because blockchain jobs still far outnumber high-quality blockchain experts, even as many professionals shift their focus toward blockchain careers. If you need to implement an entirely new blockchain network, then you need to get a person who has a solid computer science background, experience in network development, and low-level programming skills.
Please remember that this kind of project can be difficult and needs more than one developer to handle. For example, you could benefit from the rest of a project but customize its consensus algorithm—e. That is, you have specific business requirements that you want to fit into an existing blockchain.
A smart contract developer is a person who should know the internals of specific blockchain solutions. At the moment, the most popular solution that supports smart contracts is Ethereum. But there are other solutions—like Hyperledger Fabric and Sawtooth —which can be used when your business case should be supported within a private network.
This role can be critical in public networks, where there is no way to remove an invalid contact from the network without a hard fork.
There are many known security issues, and these can sometimes cause financial loss. Every developer working on smart contracts should know as much as possible about these problems and should be able to write solutions. The level of modularization should be high, and the connections between smart contracts should be able to change dynamically. For example, the address of a specific contract should be non-fixed, so if a problem occurs, the developer can just point this address to a new address with a single transaction.
These problems are sometimes less critical in private networks. But still, in some cases, you cannot guarantee that every node will be fair, and the developer should be able to handle such situations arising from the limitations of the network. In a nutshell, a DApp can be seen as the user interface for people who want to use your blockchain system. Every event coming from the blockchain needs to be correctly handled by a DApp and the DApp should also reflect the current state of the blockchain in real time.
Also, in cases where a piece of data needs to be pushed into the blockchain, a DApp developer needs to know how to achieve that. The role of the developer is to create or maintain a communication protocol for transferring data from between the blockchain and the off-chain. A significant thing to remember is the fact that every transaction especially in public chains can take some time before users can see the result. A white paper is a hybrid document that tries to sell technical aspects of a project in a way that can be understood by the average reader.
In the blockchain world, every project wants to have its own white paper—the quality of a white paper can be used to critique the project itself. There is no successful ICO without an excellent white paper. This role can be hard to fill because a writer needs to live in two contexts at the same time, having expertise in both business and technical aspects. He or she needs to create a document where the hard technical aspects are presented in a way that shows off potential business benefits. Some ICO project managers will look for consultants among blockchain engineers.
But a blockchain engineer is someone who knows how to resolve low-level issues. For ICOs, companies need a person who is able to set up a site, create smart contracts, and publish them into a public network. We hope this guide has equipped you well for the task at hand of finding the best blockchain developers!

Work With Hand-Selected Talent Within days, we'll introduce you to the right blockchain developer for your project. When Did It Start? Since the dawn of time, people have always traded. Interviewing Blockchain Developers Now that you have an overview of blockchain technology, here are some questions every blockchain application developer should be able to answer clearly in an interview.
What is a blockchain? The core concept is a block. In its basic form, it contains three things: A timestamp, which represents the creation of a block A hash of the previous block a hash is a fixed-size digest, where for a small change of input, the output is changed significantly The actual block data Block data contains all operations not yet included in another mined blocks.
In an application based on Blockchain technology, the data are stored in blocks that are synchronised chronologically. These blocks cannot be operated by any single individuals, making it one of the most robust and secure piece of technology.
Any change to the information on a Blockchain can be made with a huge amount of computing power only. Also, as the information is stored on the network, the majority should agree for the change to be reflected, making it a transparent system. Blockchain Technology is now considered to be synonymous with accountability today. Any transaction on a Blockchain can be changed only on agreement with the permission of the majority on the network, adding accountability to the operation.
Blockchain developers are high in demand and the task of recruiting someone so sought after is no easy task. As Blockchain technology has had this enormous boost, in the recent times, you would need to have new tactics out to find the best.
Before you embark on the task to find the best blockchain professional for your project, have some of these basic facts straight. These factors are dependent on the type of your organisation, your company and project culture and the work for which you are hiring for.
Depending on the nature and length of the project, you can opt for a collaboration, outsource the project, hire an expert or train your team to expertise on Blockchain. Blockchain as a commercial interest is relatively new, hence the workforce in the technology has a majority of enthusiasts who are in it for the passion of developing unique and resourceful projects instead of money. They may focus more on the aspects of cryptography and decentralisation, in place of financial gains.
Hence while hiring a developer, be sure to select a person who fits the company and project nature as well as culture. Blockchain is a relatively new field of technology and finding the right candidate through a regular or traditional method of job ad posting would rarely work.
As Blockchain is the hottest pick today and given the small number professionals in the field, they would be actively involved in multiple projects and seeking out work. Hence they need to be found from areas like blockchain forums, discussion platforms or conferences. Before you drive a hard bargain, keep in mind that blockchain developers are few in number and too high in demand today. They are also different from usual developers with unique skills.
Hence offer them the package they are looking for to get your project done on time with efficiency. Searching for the right person to take your project on the right track can often be frustrating.
Most of the blockchain developers who are experts on this domain have already earned a significant amount of money. Therefore, what they look for now is a challenge and not money. We are not making it up, it is true and you might even come across such a developer. If your project is truly groundbreaking, you might be able to get a talented developer who would be willing to work for you at a lesser payment.
Blockchain is a technology which has drawn quite an attention in the last few years after the price of Bitcoin went all-time high. Things like smart contracts and decentralized apps are now becoming a part of every industry and changing the way we have been dealing with currency and everything else.
As a fintech solution, it has been lauded from the experts worldwide. It reduces the time of transaction and brings more transparency with peer-to-peer architecture. It decimates the third-party intervention and makes every transaction absolutely anonymous. They also have the ability to transform the traditional economy and make it much more productive. With this technology, our dependency on banks come to an end and we become the sole owner of our money.
Currently, cryptocurrency is mostly associated with the crypto market because of its limited implementation. But it is gradually becoming a part of every business with its by-products such as trading platforms, cryptocurrency wallets, etc. The blockchain-based applications and websites are also becoming a part of every domain. The best things about this technology are its vast adaptability and flexible structure which makes it affordable to the business of every size and nature.
This technology can significantly reduce the cost of your operations and also secure the data in the most robust fashion. In this article, we would focus on the following points:. It is very hard to quote an exact price for this service right now and there are many reasons behind this. First of all, blockchain is still considered to be in its initial phase and it has not yet received a plenary approval because of its association with cryptocurrency. There are many industries and companies which do not want their operations to run on a decentralized structure.
However, the adoption of this technology worldwide is significant and it got a chance for the developers to make the highest profits out of it. The cost for the development of blockchain-based projects is currently very high but there are ways to bring the price down. The best thing to do is hire an offshore development service which could provide developers who can deliver the website or application at a very reasonable price. There are countries which are preferred for these services and most of the projects are bagged by the developers over there.
Countries like India, Ukraine, Vietnam, and the Philippines have a large number of blockchain experts who provide their services at a very low price as compared to their counterparts in the US, UK and most of the European countries. Notably, the aforementioned countries are also a preferred destination for outsourcing because of the same reason. They provide cheaper and reasonable services which are more sustainable for your business.
Developers from each country have their own pricing model and they charge an hourly basis. There are basically two types of hourly rates which are average and median. The best way of getting a blockchain project developed is to hire blockchain developers offshore who could deliver what you want at a very cheap price.
With such a remote development team, you can make things easily possible for you. The coding could not be up to the mark but considering the price, you would definitely choose them. With altcoins, the creation of digital assets has become a lot easier. However, it should not be taken lightly as a high level of expertise is required for their creation.
The surge in the number of ICOs has also resulted in a slew of coins which are giving access to different services now. Although, there have been many scams done in the name of crowdfunding projects and people are losing faith in it. Still, there is a large number of entrepreneurs who want to use this ingenious method and want to create to materialize their vision through this medium.
It is a much more feasible way of raising funds and gives a boost to every other business idea. When it comes to the creation of cryptocurrency, there are few things you need to consider:.
You need to have experts by your side if you want the development process to be seamless. You also need to have other professionals except for developers such as marketing professionals and QA specialists.
The targeted customers can be easily acquired if you have a flawless strategy. Then only the credibility of your project is established and you present it among the audience. The communication is the most critical aspect of a crowdfunding campaign and you need to get it right. You need to analyze the trends of the market and figure out a way to earn the profit. There are a few essentials which have to be integrated into the framework in order to make the campaign more engaging.
To make your project more efficient, you need to show more competence and in every segment of your project including marketing. You may even have a marketing advisor who could lead the whole process in the right direction.
The development of a crypto wallet must be done by an expert, it should be created using the most advanced languages.
Developers generally use the same programming language which is required for making a blockchain network. Currencies like Bitcoin and Ethereum have got roped in with the regulations around the world. Thus, it has become necessary for you to follow them as well. For adhering to this guideline, you need to have a legal advisor for every blockchain product. The end product should be able to serve the users on all the platforms such as Web, Android, and iOS.
These platforms have been proven very satisfactory and their usage has produced impressive results as well. You can either create a bundle of programs or go for standalone software. Blockchain is evolving and there could be something new every month which could change the direction of your development campaign. There are some specific tools and applications which make the process easier.
With these applications, you can build customized projects very easily. They are a few things that you need to be specifically careful about while creating bespoke software. Their creation has increased by leaps and bounds, they are now becoming a part of various industries:. Any change to the information on a Blockchain can be made with a huge amount of computing power only. Also, as the information is stored on the network, the majority should agree for the change to be reflected, making it a transparent system.

Searching for the right person to take your project on the right track can often be frustrating. Unfortunately, in a high demand field like Blockchain technology, you need to offer more to entice the right resource!
So, how do we identify between a good Blockchain developer and a great one?
HOW MUCH DOES IT COST TO HIRE A BLOCKCHAIN DEVELOPER?
You can also create a network where digital coins symbolize real assets dollars, grams of gold, or oil barrels. In this case, the size of the money supply should vary depending on the number of assets under control collateral of the owners of the blockchain network. For example, Tether has 2. In a binding offer you need to change the cryptocurrency icon - its graphic image. It should be simple, stylish and fit into the overall concept of your blockchain network you have invented.
If in the created blockchain network coins are generated by mining, you need to choose an encryption algorithm SHA, X11 or others , a mechanism for achieving consensus PoW, PoS , PoI or others and a reward for generating a block - the number of coins that miners receive when creating block. Too small reward will not attract people, as it will be economically inexpedient to engage in mining. Too much will attract too many people, which will immediately increase the complexity of the network and, again, scare people away.
Therefore, you need to choose the middle option, for example, as in Bitcoin or Ethereum. Network ports. Through them, the blockchain network interacts with the Internet, so the choice should be approached with the utmost seriousness. Four ports are required — two for system operation and two more for testing.
And on the resource of these ports should not encroach any other applications. When changes are made to the fork network, it needs to be tested - run through all usage scenarios. You need to do this many times and preferably on different devices. Both of these options are highly undesirable, as a non-working and unreliable network will scare users away or cause the ruin of your business. This is especially important in cases where the blockchain is created as a decentralized platform with irreversible transactions.
Now let's look at the process of launching the blockchain network at special sites that developers use to launch crypto startups. The most popular of them is Ethereum, so we will consider the launch of the network using its example.
First you need to download and install a cryptocurrency wallet , for example Ethereum Wallet. It can be downloaded from the official website of Ethereum , Github or another resource.
After installing the wallet, you need to create an account in the Ethereum network. Gas costs money, so beginners are advised to check the performance and functionality of their projects in the test network before spending real money on them. Knowing this, you can start creating a personal blockchain network within Ethereum. To do this, we need a smart contract to launch new tokens.
It can be written from scratch, but this is not our way. Easier and safer if you're new is to copy code of the desired smart contract from the official site. After that, a new window will appear, where at the bottom of the screen you need to paste the previously copied token-contract code.
Here you need to specify the name and symbol of the token, the maximum size of the money supply and how many parts of the token is divided the number of decimal places. When the contract code is inserted and the data is entered, you need to click "Deploy", and if there is enough gas in the wallet, the token-contract will start.
This is the easiest way to create a network based on Ethereum blockchain. Such a network will not stand out in any way and there will be no benefit from it either. To create something more useful, use the simple official guide of the platform to improve the standard token and give it unique properties. Standard token is suitable only for the simplest cases of business tokenization or acquaintance with the world of blockchain and cryptocurrency.
In other cases, it will simply not be noticed due to the presence of thousands of other similar coins. If you do not want to understand all this and do everything yourself, you can hire a blockchain developer company. So you can save time and nerves, since the creation of the blockchain network will be handled by experienced professionals who know this inside out.
The development time and cost of services of such a company depends on the nature of the network being created. For example, if this is the tokenization of business through the initial offer of coins at the Ethereum site, it is somewhere around thousand dollars and a couple of months. The most simple projects cost thousand dollars and deployed within a month.
The cost of services of development companies usually includes the following: - compilation of the blockchain network core; - development of wallets for different operating systems and device types; - deploying multiple primary nodes network nodes ; - creation of block explorer and mining pool.
Network promotion If your blockchain network is not for internal use, it should be promoted to the masses. To do this, you need a separate budget and several specialists who will create a website, engage in advertising and informing the community. You can also run airdrop and bounty campaigns, this will reduce the budget and allow you to promote the network in several language zones.
It will not hurt to enlist the support of advisers - authoritative personalities in their field, who will help you as advisers. Access to the exchange On the cryptocurrency exchanges, the market price of tokens is being formed, which in the plans of developers should grow as soon as their coins get into listings.
Therefore, after the completion of the technical stages of development, testing and deployment of the blockchain network, coins are attempted to be included in the cryptocurrency exchange lists.
We need to start with new and small exchanges that want to stand out due to a larger list of tokens in the listings or the presence of exotic bitcoins. It should start exactly from such sites.
The listing procedure depends on the site. So, in Poloniex it is free, but tough: you need to register, go through verification and prove the benefit of the token to society. At other sites, the requirements may be relatively simple, but the procedure can cost money - from 1, dollars for little-known sites to , dollars for the largest cryptocurrency exchanges.
Creating a blockchain network unnecessarily is a waste of resources and time. Therefore, before starting, make sure that you really need a new blockchain. Then determine the budget and level of programming skills to understand which development method to choose: - create fork of existing network - price and time depend on your quickness and number of changes; - use a specialized platform - easy, fast, inexpensive; - assemble a team of blockchain developers - long and expensive; - outsourcing is fast and there is a guarantee of quality, but it costs a lot of money.
If you do everything right, the test network can be deployed in an hour. To make something unique and competitive, it will take several months. For the introduction of the blockchain in your own business, you need up to six months. At the same time, you need to remember about the risk: your cryptocurrency cannot shoot and not pay off, losing among the 1, existing coins, so measure it seven times and then lay out the money.
But if you do it for the sake of interest or gaining skills - go for it! Why do you need a blockchain network 2. How to create a blockchain network using fork 3. Where to get the source code of the blockchain 4.
You may have to compromise a little on the quality of coding but the price is a big factor which draws the attention of entrepreneurs. And you can also find freelancers who charge even lower than the companies. If you have sufficient time to monitor the progress of your project, this option would be best for you. With the advent of blockchain technology, many things are changing now.
The companies are also prone to hiring more female development to bring a greater level of management and compliance in the process. However, it is not very easy to find female blockchain developers when their overall headcount is lesser than required. Finding a female developer and hiring will take more time and resources as well.
The propensity of women towards technology has also grown in the past few years and we can see more of them in this booming industry. Though small in number, but female developers do exist and their contribution is increasing rapidly so does the demand.
It may take you some time but you would be eventually successful in finding one. There is no platform dedicated to women developers only. You need to have a sweeping approach for finding them with communities and social media. Most of the blockchain developers who are experts on this domain have already earned a significant amount of money.
Therefore, what they look for now is a challenge and not money. We are not making it up, it is true and you might even come across such a developer. If your project is truly groundbreaking, you might be able to get a talented developer who would be willing to work for you at a lesser payment.

HOW MUCH DOES IT COST TO CREATE A CRYPTOCURRENCY
However, the opposite is often true. By the time you count the cost of recruitment, onboarding, benefits, and salaries, you can easily spend more to hire and retain developers than to contract with a firm. Even if your project requires ongoing development or support, outsource development providers often provide cost savings over the long haul. Depending on the outsourcing model you select, benefits and administrative expenses might be absorbed by the development company.
Further, you can use a development firm only when you need them. Once you hire employees, you have to pay them whether you have work or not.
Outsourcing used to be synonymous not only with low cost, but with with poor quality as well. Such is still the case with many Indian-based outsource providers, but not necessarily so in Western Europe.
Some of the best developers in the world work for Ukrainian or Israeli outsource providers, and the quality of their work is unsurpassed even by US-based firms. Moreover, reputable outsourcing firms use strict frameworks that guarantee quality every step of the project.
If you decide that you want to outsource your blockchain project to a developer, you must decide if you will contract with a development company or a lone developer. The decision depends on more than the scope of your project. If your project complexity justifies multiple hands on deck, you will find it easier to outsource your project to a development company.
An outsource firm will have multiple developers on staff, and will have a framework in place to ensure excellent teamwork throughout the project. Your project will be lead by a manager whose job it is to get your project completed to spec and delivered on time.
If you choose to hire multiple individual developers, you will have to manage every aspect of the project yourself. You will likely find that getting two or three remote developers to work together efficiently is nearly impossible. Even if you hire a project manager to do the dirty work for you, the quality of the final product will be questionable at best. For a simple project, a sole contractor may be able to build your blockchain for you.
However, commercially-viable blockchains that are fast, scalable, and secure are rarely simple. While there are a few icons in the industry who have single-handedly built some amazing blockchain solutions, their breed usually picks their employers, rather than the other way around.
A developer must possess a unique set of skills to work effectively in blockchain and cryptocurrency technologies. Blockchain developer skills are unlike those of any other programming discipline.
While blockchain developers work in code, just like those who work in Java or Python, the are some unique characteristics you must look for when seeking a blockchain developer. First, every blockchain developer must have a solid background in blockchains, cryptography, cryptocurrencies, the Ethereum network, ledgers, consensus methods, decentralized technologies and P2P networks, data security, web technologies, and various high-level programming languages.
Lack of knowledge in these areas translates into a lack of understanding of the fundamentals of distributed ledger technology. The adoption of smart contracts across a multitude of industries requires a thorough knowledge, here, also. Even though your project might not have a legal or financial application, smart contracts could still be a crucial part of your offerings. Speaking of legal and financial applications, since blockchains are seeing rapid adoption in these sectors, it is important for developers to understand the unique requirements and regulations of the industries they serve.
Chances are, you will not find qualified lone blockchain developers on conventional job boards, or Facebook. Blockchain developers like to hang with others of their species, and you will find them on geek job boards, at Bitcoin conferences, on Reddit or GitHub, or on similar sites. Good blockchain developers are never idle, and you will find yourself in competition with other companies for those worth hiring. It has really gone beyond innovation and now gives the whole world much more than a new technology offers.
That makes Blockchain Developer a precious asset and you cannot expect them to work for you at a cheap price. However, as the technology is expanding itself, several individuals are now opting to become an expert in this domain. With this marathon, it is becoming easy for any enterprise to hire blockchain developers.
But at the same time, it is equally important to take care of the quality of the project. So the question is how much you need to spend on hiring a blockchain developer? The answer to this question cannot be a one-liner as there are many factors deciding the price.
What you can do is learn this language and know exactly what you want out of this technology, then you will determine the right price for your project. Currently, many aspiring is drawn towards blockchain just because it got so popular and bitcoin made quite a few people wealthy.
You need to understand that learning takes time, patience and persistence. Those who started learning it a few years earlier could be considered experts, but those who have just begun will take some time to blossom.
The number of developers is estimated to be around 20 million worldwide and only 0. Approximately, there are only 6, developers who know how to build an efficient blockchain network. Therefore, the supply of experts who could create Dapps is quite lesser than required. Even then, the technology is being adopted by many industries at a swift pace and it is becoming a part of major domains that affect our lives on a daily basis.
Many industry giants are now introducing their own projects which are empowered by blockchain technology. Companies like Porsche is going to implement this technology in their cars in the near future. Projects like this will imbibe this technology deep into our lifestyle soon.
Not just the corporate but also the governments have started considering its adoption now. Countries like Georgia, Sweden are now testing blockchain as a means for registration of land.
Besides all this, the slew of crypto-based crowdfunding campaigns has contributed greatly to making this technology popular. It has also materialized many business ideas which were considered unfathomable before the onset of this technology. The pace at which blockchain is being introduced into different domains clearly indicates that it would become a great contributor in the digital economy as well.
And it was for those whose proficiency level was mediocre, if you are good, you can make much more than this. Other than that, the geography also plays a role as developers belonging to different countries have different charges. You will find developers charging this much in countries like Poland, Ukraine or Bulgaria.
You may have to compromise a little on the quality of coding but the price is a big factor which draws the attention of entrepreneurs. And you can also find freelancers who charge even lower than the companies. If you have sufficient time to monitor the progress of your project, this option would be best for you. With the advent of blockchain technology, many things are changing now.
The companies are also prone to hiring more female development to bring a greater level of management and compliance in the process. However, it is not very easy to find female blockchain developers when their overall headcount is lesser than required. Finding a female developer and hiring will take more time and resources as well.
The propensity of women towards technology has also grown in the past few years and we can see more of them in this booming industry. Though small in number, but female developers do exist and their contribution is increasing rapidly so does the demand.
It may take you some time but you would be eventually successful in finding one. There is no platform dedicated to women developers only. You need to have a sweeping approach for finding them with communities and social media. Most of the blockchain developers who are experts on this domain have already earned a significant amount of money. Therefore, what they look for now is a challenge and not money. We are not making it up, it is true and you might even come across such a developer.
If your project is truly groundbreaking, you might be able to get a talented developer who would be willing to work for you at a lesser payment. Blockchain is a technology which has drawn quite an attention in the last few years after the price of Bitcoin went all-time high. Things like smart contracts and decentralized apps are now becoming a part of every industry and changing the way we have been dealing with currency and everything else.
As a fintech solution, it has been lauded from the experts worldwide. It reduces the time of transaction and brings more transparency with peer-to-peer architecture.
It decimates the third-party intervention and makes every transaction absolutely anonymous. They also have the ability to transform the traditional economy and make it much more productive. With this technology, our dependency on banks come to an end and we become the sole owner of our money. Currently, cryptocurrency is mostly associated with the crypto market because of its limited implementation. But it is gradually becoming a part of every business with its by-products such as trading platforms, cryptocurrency wallets, etc.
The blockchain-based applications and websites are also becoming a part of every domain. The best things about this technology are its vast adaptability and flexible structure which makes it affordable to the business of every size and nature. This technology can significantly reduce the cost of your operations and also secure the data in the most robust fashion.
In this article, we would focus on the following points:. It is very hard to quote an exact price for this service right now and there are many reasons behind this. First of all, blockchain is still considered to be in its initial phase and it has not yet received a plenary approval because of its association with cryptocurrency.
There are many industries and companies which do not want their operations to run on a decentralized structure. However, the adoption of this technology worldwide is significant and it got a chance for the developers to make the highest profits out of it. The cost for the development of blockchain-based projects is currently very high but there are ways to bring the price down. The best thing to do is hire an offshore development service which could provide developers who can deliver the website or application at a very reasonable price.
Hire Freelance Blockchain Developers
That is why most startups follow a simpler, faster and more reliable path - they launch their own blockchain network using the fork of the existing cryptocurrency. To create a blockchain network using a fork, you need to do three things: download the source of the blockchain framework, make changes to it, test it.
And, of course, run. Usually the existing cryptocurrency framework can be found on the Github service. It is the world's most popular open source collaborative software development site. If the framework is not on Github, you should look for it on SourceForge. To find another blockchain framework , you need to:.
Register on the site and enter the corresponding request in the search box in the upper left, for example, Ripple. So we copy the Ripple framework repository into our account. You can make changes to the source code of the framework either manually or using special applications. The last option is much faster and easier, so it is better to use it. In the Windows operating system, this is done through the Search and Replace program or its almost one hundred percent equivalent HandyFile Find and Replace.
With this software, the first thing you need to change the name of the network and coins. Instead of the original names and symbols, we enter our own, replacing them with all variations. Suppose we take the Bitcoin blockchain network as the source code , and the name of our new crypt, TestCoin. When choosing a name, you need to find something short, conspicuous and memorable, because this is the first thing investors and users will see when they get acquainted with your blockchain network.
Do not forget about the exchange designation of the coin - the abbreviation BTC. It also needs to be replaced. However, before you do this, you should check what abbreviations are already used.
For example, the abbreviation for the TestCoin TTS coin is already taken - a coin with such an abbreviation symbolizes the TittieCoin cryptocurrency. Number of coins. Next, you need to specify the maximum number of tokens for our network. It can be unlimited, as in Dogecoin and Ethereum cryptocurrencies. In this case, you need to take into account the fact that your token must be constantly used and destroyed, otherwise its money supply will constantly grow and, as a result, the coin will constantly depreciate.
Another option is to limit the size of the money stock , as in the Bitcoin network 21 million coins , Litecoin 84 million coins or IOTA 2. The size of the restriction, as a rule, is chosen quite arbitrarily, focusing only on the fact that there are not too many coins and not too few.
You can also create a network where digital coins symbolize real assets dollars, grams of gold, or oil barrels. In this case, the size of the money supply should vary depending on the number of assets under control collateral of the owners of the blockchain network. For example, Tether has 2. In a binding offer you need to change the cryptocurrency icon - its graphic image. It should be simple, stylish and fit into the overall concept of your blockchain network you have invented.
If in the created blockchain network coins are generated by mining, you need to choose an encryption algorithm SHA, X11 or others , a mechanism for achieving consensus PoW, PoS , PoI or others and a reward for generating a block - the number of coins that miners receive when creating block.
Too small reward will not attract people, as it will be economically inexpedient to engage in mining. Too much will attract too many people, which will immediately increase the complexity of the network and, again, scare people away. Therefore, you need to choose the middle option, for example, as in Bitcoin or Ethereum. Network ports. Through them, the blockchain network interacts with the Internet, so the choice should be approached with the utmost seriousness.
Four ports are required — two for system operation and two more for testing. And on the resource of these ports should not encroach any other applications. When changes are made to the fork network, it needs to be tested - run through all usage scenarios. You need to do this many times and preferably on different devices. Both of these options are highly undesirable, as a non-working and unreliable network will scare users away or cause the ruin of your business.
This is especially important in cases where the blockchain is created as a decentralized platform with irreversible transactions. Now let's look at the process of launching the blockchain network at special sites that developers use to launch crypto startups. The most popular of them is Ethereum, so we will consider the launch of the network using its example. First you need to download and install a cryptocurrency wallet , for example Ethereum Wallet.
It can be downloaded from the official website of Ethereum , Github or another resource. After installing the wallet, you need to create an account in the Ethereum network. Gas costs money, so beginners are advised to check the performance and functionality of their projects in the test network before spending real money on them.
Knowing this, you can start creating a personal blockchain network within Ethereum. To do this, we need a smart contract to launch new tokens. It can be written from scratch, but this is not our way.
Easier and safer if you're new is to copy code of the desired smart contract from the official site. After that, a new window will appear, where at the bottom of the screen you need to paste the previously copied token-contract code. Here you need to specify the name and symbol of the token, the maximum size of the money supply and how many parts of the token is divided the number of decimal places. When the contract code is inserted and the data is entered, you need to click "Deploy", and if there is enough gas in the wallet, the token-contract will start.
This is the easiest way to create a network based on Ethereum blockchain. Such a network will not stand out in any way and there will be no benefit from it either. To create something more useful, use the simple official guide of the platform to improve the standard token and give it unique properties.
Standard token is suitable only for the simplest cases of business tokenization or acquaintance with the world of blockchain and cryptocurrency. In other cases, it will simply not be noticed due to the presence of thousands of other similar coins.
If you do not want to understand all this and do everything yourself, you can hire a blockchain developer company.
So you can save time and nerves, since the creation of the blockchain network will be handled by experienced professionals who know this inside out. Today we have more than different cryptocurrencies, so creating a token that will stand out from the crowd is a tough task. People do not trust the new form of money yet as they believe that the crypto industry is full of scams. This way, it takes much time and effort to convince the community that the new crypto coin is a worthy investment.
We will briefly describe the whole process of cryptocurrency creation and provide the overall estimates. The team of experts is essential. To successfully launch a coin on the market, you need a team of advisors in marketing, software developers, cybersecurity specialists, PR managers and so on. These people will help you find investors to give credibility to the project.
Also, it is necessary to find an advisor in cryptocurrencies to guide you through the market. Communication with your target customers is also critical.
You need to understand how to promote new cryptocurrency and earn a profit. Thus, it is essential to cater to the needs of your audience, communicate your main benefits, show your competitive edge, and so on. Here is why you need a marketing advisor, who will plan your marketing activities. Once the marketing strategy is molded, you can proceed to the blockchain network development. It makes no difference what technology to use.
Another critical moment — how to make your cryptocurrency legal. Today, even the most well-known cryptocurrencies like Bitcoin and Ethereum face tough regulation issues all across the globe. This way, the legal advisor is mandatory for every blockchain product. A cryptocurrency wallet is a digital application like the real wallet used to store, send, and receive digital currencies securely.
Most coins cryptocurrencies have official wallet apps or a few recommended third-party wallets. In other words, to use any cryptocurrency, you will need to use a cryptocurrency wallet.
Usually, the application is built for three different platforms: Android, iOS, and Web. Still, it requires a considerable amount of work that needs to be done. Another option is to build a standalone application. Every approach has its own advantages and disadvantages.
You will need a dedicated team that consists of several senior developers, a business analyst, a project manager, and a QA engineer. Blockchain has changed over recent years. It has evolved from a cumbersome tool used by crypto enthusiasts into a scalable decentralized platform for industry-specific applications. Today, these blockchain-based applications are used by both niche startups and huge corporations like Kodak.
