Frequently Asked Questions

What are Blockchain development services?

Building, designing, and maintaining blockchain applications and systems are central to blockchain development services. Blockchain application development companies bring to the table unique features to spin apps that remedy issues related to transparency, trust, traceability, and security in the supply chain, health care, financial institutions, media, and government sectors.

Leading Blockchain companies typically offer a range of custom blockchain solutions, including smart contract development, wallet development, cryptocurrency exchange and trading app development, auction development, DeFi, and DEXs development, among others.

What are the types of Blockchain technology?

There are mainly four types of blockchain technology.

  1. Public Blockchain: The clue is in the name. A public blockchain is a permissionless distributed ledger technology that allows anyone to join and participate in the activities of the ledger free of charge.
  2. Private Blockchain: As the name goes, a private blockchain is a permissioned distributed ledger technology that operates in a restricted network, such as a single firm or an organization, or is controlled by a single authority.
  3. Hybrid Blockchain: It’s a combination of Public and Private Blockchain network features. In other words, organizations can build blockchain networks through blockchain technology using permissionless public and permission-based private systems. Such networks allow businesses to determine which data could be made public in nature and which should be avoided from the public eye.
  4. Consortium Blockchain: It constitutes both Private and Public Blockchain features and is run by pre-selected, privileged members of different organizations who work together on this decentralized network.

Which are the most popular Blockchain platforms?

Well, there are 20+ blockchain platforms out there. If you look at the top 5, it’s Ethereum, IBM Blockchain, ConsenSys Quorum, Hydrogen Molecule, and Hyperledger Fabric.

Despite multiple blockchain platforms out there, Ethereum is the oldest and most overused. Launched in 2013 Ethereum platform is synonymous with the Bitcoin blockchain network in terms of decentralization features, as it offers authentic decentralization features with the help of smart contracts.

What services are offered by Blockchain companies?

As mentioned above, services offered by leading Blockchain companies include building distributed ledgers for public and private blockchains, smart contract development, wallet development, cryptocurrency exchange and trading app development, auction development, and blockchain mining solutions, among others.

How can blockchain development companies make businesses more powerful?

In the past, businesses had to rent spaces in data centers to store data, making storing data an expensive proposition. No more! Now the best Blockchain development companies offer in-built encryption features in their apps which could help your business with secure data storage and transfer. Besides safe data storage, it’s worth mentioning here that Blockchain applications could help bolster business operations by injecting a new level of transparency, efficiency, and security into your processes.

Which programming languages are used by Blockchain companies?

Solidity ranks first on the radar of Blockchain companies with regard to the top programming languages used in Blockchain. Freshers and senior developers can learn this programming language’s A, B C quite comfortably. Other programming languages that top Blockchain companies typically focus on include C++, Rust, JavaScript, Clarity, Go, and Python.

Do blockchain developers provide blockchain project consulting?

Yes, blockchain developers provide blockchain project consulting services to new blockchain firms and thus significantly contribute to their business prospects. Let's see how they do it. First, blockchain consultants would like to analyze this distributed-ledger technology's impact on the company. Once the analysis is over, a basic plan is drawn up for blockchain integration, followed by steps to implement the same. During the implementation process, the consultants will likely explore potential issues and then hold running conversations with all stakeholders to create apt, ingenious solutions.

What questions should I ask before hiring a Blockchain development company?

Let me tell you beforehand that hiring a blockchain development company could prove to be an arduous task as these companies have multiplied in recent years. However, GoodFirms has made it easy for you to locate the right partner as we have listed all the top, credible, and globally renowned Blockchain development companies under our roof.

However, if you want to take the road less traveled and find your perfect Blockchain development partner with the sweat of your brow, then Good Luck.

For those interested, here's a short list of questions you must ask the leading Blockchain app development company before hiring them. Here they go:

  • What's their total experience in developing blockchain solutions?
  • Have they ever developed blockchain apps for an industry like yours?
  • What's their developer strength?
  • What's their costing approach?
  • How many Blockchain projects have they delivered so far?
  • Which technology stack they use?
  • Which Blockchain platforms are they attuned to?
  • How will Blockchain benefit your business?
  • What steps would they adopt while integrating blockchain technology into your business operations?

How can I hire Blockchain developers, and what essential skills should I consider?

Hiring blockchain development companies is challenging, but hiring Blockchain developers is equally time-consuming and complex. However, we are here to make things easier for you. So let’s quickly point out the most logical way to engage with top blockchain developers:

How do Blockchain development companies approach security and privacy concerns?

Blockchain technology is known to be bulletproof as it boasts several inherent security features, including immutability, transparency, encryption, and decentralization. With all these unassailable features, data privacy and security are a cinch with blockchain.

In layperson's terms, blockchain, also dubbed as distributed-ledger technology, stores data bulletproof. How? Being a distributed ledger means every individual in the blockchain network can access the ledger. This means any tiny change in a member's ledger will immediately come to the notice of the other network members, who may or may not approve of the change. Thus the technology acts as a helpful hedge against data corruption.

Additionally, users need not reveal their identities or display identity proofs to transact, and even the amount can be encrypted as only the sender and receiver would know about it.

Do blockchain developers specialize in industry-specific blockchain solutions?

Yes, blockchain developers specialize in industry-specific blockchain solutions. Currently,  blockchain developers plan, develop, deploy, and maintain apps for both public and private sector companies, including supply chains, financial institutions, media, and healthcare, among others.

Can Blockchain developers help with integrating IoT devices with Blockchain technology?

Yes, Blockchain developers can help integrate IOT devices with Blockchain technology and help fight the challenges the IOT devices face in the form of security vulnerabilities, inferior interoperability, privacy, and lack of industry standards.

Blockchain hedges IoT devices with security and adds transparency.
