Blockchain developers have a strong mix of skills in the areas of computer networking, cryptography, and algorithms and data structures. But they also have experience with at least one specific type of blockchain, like that of bitcoin or Ethereum. It’s important to know whether you will build on existing open-source technologies: Only a rare few will succeed in making something brand new, but that’s often unnecessary.
Trusted by leading brands and startups
Blockchain is a special database which gained popularity because of cryptocurrencies adopting it, especially bitcoin. Blockchain development is used together with cryptocurrencies to implement peer-to-peer (P2P), distributed services. Blockchain’s primary usage is large, public databases that are immutable—in other words, they can’t be tampered without spending massive amounts of resources.
Blockchain is spread across a world of cryptocurrencies and platforms for distributed applications. When you are looking for a blockchain developer to fill a specific position, posting a generic blockchain developer description in your job ad will bring applications from people who may only know bitcoin-like blockchains or only be proficient in Ethereum. Targeting the correct type of specialist is key to an effective job description.
