Blockchain's meaning originally comes from obstruct series. It's a continuously growing list of records, known as blocks. The block are all connected and secured using cryptography. Each block comprises generally a hash pointer for a link to a previous block, a timestamp and trade data.

By design, blockchains are inherently resistant to modification of the information. Functionally, a blockchain can serve as "an open, distributed ledger that could record transactions between two parties efficiently and in a verifiable and permanent way.

For use as a distributed ledger a blockchain is typically handled by a peer-to-peer system collectively adhering to a protocol for validating new blocks. Once recorded, the data any given block can't be altered retroactively with no alteration of all succeeding blocks and a collision of this network majority.

It is highly possible that you are linking the blockchain together with the main technological innovation of Bitcoin -- a money with which trades are made with no middle men.

The block series stands as evidence of all of the trades on the network. A block in this situation is the "present" part of a blockchain that records some of the recent transactions and once done, then goes into the blockchain as permanent database.

Hence the blockchain system was designed to utilize nodes arrangement to dictate transactions and prevent the fraud described previously. The Bitcoin network orders trade by putting them together into classes known as blocks, each block contains a certain amount of trades and a link to the previous block.

One illustration is blockchain.info -- it's a bitcoin wallet and block explorer service. Launched in August 2011, the service provides data on recent transactions, mined blocks in the bitcoin blockchain graphs on the bitcoin market, and data and resources for developers.

It's too close to the name of the aforementioned brand name. So it's very good thing that other brand decided to shake things up and choose different name.

Bonus narrative:

Would you know that the first distributed blockchain was conceptualised by Satoshi Nakamoto at 2008 and implemented the next year as a core part of the digital currency bitcoin, where it functions as the people ledger for all trades. The creation of the blockchain to get bitcoin made it the very first digital money to address the double spending issue, without the use of a trustworthy authority or server. The bitcoin design has been the inspiration for other applications.
