Blockchain is a relatively new concept that has revolutionized every industry because of its wide applications. It originally started as a distributed ledger with clear record of every transaction. The first blockchain technology was implemented for Bitcoin, the first cryptocurrency. Blockchain is a growing list of records, called blocks, that are linked using cryptography.
The idea behind that is using each block to connect to the next block. That is possible because, within each block, there is a cryptographic hash that relates to the previous block, along with a ledger of transactions in a data format called Merkle tree.
Because it has a timestamp, it becomes virtually tamperproof. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.” For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without alteration of all subsequent blocks, which requires consensus of the network majority
Given how recent it is, there are no established governing agencies for blockchain. Its direct application in cryptocurrencies, and the currencies themselves, are not recognized in many countries. However, The Global Blockchain Business Council (GBBC) has membership from several organizations across the globe. It is a network of all the businesses that have pledged to work on blockchain as an open-source platform to enable the industry-disruptive capabilities it has
GBBC does not have any certification processes. Only companies may be a member of this league. So, for certifications, we turn to other providers. The certification that they offer varies differs from the training provider and the target audience they assume.

Most Blockchain courses provide an overview of Bitcoin, Hyperledger, Ethereum, and Multichain blockchain platforms. They are taught application and use of tools like Ganache, Truffle, Meta Mask, and Geth to build Blockchain applications along with setting up a private blockchain network using Hyperledger Composer and deploying smart contracts on Ethereum.
One such training provider is Blockchain Training Alliance. Its certifications include
It also provides several courses such as
In most cases, the training providers themselves will set the syllabus and guidance on how to go about any course. They will determine the levels and the title for each of those courses. Given the newness to it and the lack of standardization, it is hard to describe any individual certification. That being said, there will be some commonalities.
The foundational exam will test individuals on
