We are seeking a skilled and experienced blockchain developer to assist us with our Ethereum smart contract development project. When someone wants to send information through Blockchain, they start the process by creating a block. This will be verified by hundreds and thousands of computers across the internet. The block which is thus verified is added to a chain, creating a unique record. Every time a new set of transactions is added, that data becomes another block in the chain.

Blockchain platform development
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. In the early 2000s, 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.
Unlike with the original email context for hashcash, on average, a new bitcoin block is signed every ten minutes. 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.

This latter problem is called double spending and also is solved by bitcoin. 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. 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.
Screening Process
Every developer working on smart contracts should know as much as possible about these problems and should be able to write solutions.
