Frequently asked questions

What does a blockchain company do?

Blockchain companies may perform many different activities around cryptocurrency, cybersecurity, and technology. These companies provide blockchain solutions to benefit financial institutions, government agencies, and even startups.
At the most basic, blockchain companies provide consultancy and development services in blockchain, creating the foundation for cryptocurrency development and trading. How businesses do that can vary. Some might focus on developing blockchain applications, while others build ledger technology systems for the financial services industry.
Many companies build, test, and deploy blockchain frameworks for customers, and some function as networks that let users deposit, barter, and earn income on their digital currencies, like bitcoin. The blockchain network functions as a public database, creating a secure platform where people can buy and sell bitcoin.
A blockchain agency might develop its own cryptocurrency platform, but many also sign smart contracts with other businesses, developing them blockchain apps and frameworks for a fee.

What are the major blockchain companies?

Because the blockchain industry is still so new, top blockchain platforms are still emerging. However, companies like Steem, Ripple, Chain, Intellectsoft, and Altoros have already differentiated themselves when it comes to blockchain software development and technology.

How do blockchain companies make money?

Blockchain companies can make money in multiple ways:
  • Earnings money from subscription fees and transaction fees from corporations and institutional investors using the technology the business developed
  • Developing software for a purpose like creating a supply chain between businesses, then selling that software to fintech businesses
  • Providing software services to businesses to help with tasks like cloud storage and digital asset and data management
  • Contract agreements and initiatives to provide blockchain infrastructure and create apps for other companies
  • Efforts to increase crypto token values and then sell those tokens for profit

Can I invest in blockchain technology?

You can invest in blockchain technology in multiple ways:
  • Invest in bitcoin penny stocks
  • Crowdfund a crypto startup that’s bringing alternative coins to market
  • Provide angel funding to startups and tech providers to get in on new cryptocurrency developments
  • Buy stock in a blockchain technology agency

Do all cryptocurrencies use blockchain?

Blockchain technology allows cryptocurrencies to record transactions, and most crypto relies on blockchain. Bitcoin and Ethereum both use blockchain, and Facebook’s crypto platform, Libra, also uses blockchain. Even banks are moving to use distributed ledgers to help streamline settlement systems. Blockchain technology is quickly becoming more popular and its use is becoming more widespread.
