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 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.
