I’ve been trying to figure out how to explain Blockchain, Cryptocurrency, and ICOs in a short elevator pitch.  Got a great suggestion from “Blockchain Business Consultants” (www.bchainconsult.com) I’m sharing here.  If you like it, please feel free to use it.  If you have suggestions to make this better (but not longer), please let me know.

How to Explain Blockchain, Cryptocurrency, and ICOs in one short paragraph Elevator Pitch:

A blockchain is a secure distributed ledger or database where past “blocks” of entries are “locked in” so securely that you cannot alter them.  It is not run by a company or any trusted party—but a computer network.  A network of computers reach a consensus on the current block of transactions and once a majority agree, the new block of transactions is locked onto the blockchain database.  It’s a virtually unhackable, highly secure distributed ledger that can replace intermediaries like banks, or any company and authority now relied on as “trusted party” or controller of an information system.  With “Smart contracts” in the blockchain system, executed by the computer network when agreed upon conditions are met, you can conduct transactions without lawyers and middlemen.  Blockchain is used for virtually unhackable digital currency to pay for online transactions (cryptocurrency—like Bitcoin, Ether, others) and for a new means of raising funds:  an “Initial Coin Offering” where you produce a “token” you can trade on a blockchain that, combined with Smart Contracts, provides rights to buyers to use services or buy products.

yes it does not look bad
It is necessary to study this proposal and understand its advantages

This statement is not true.

The process does not require a majority to agree on the transactions for the current block. Each miner works on their own, completely different block.  Once a single miner to completes a valid proof-of-work, that block is added to the blockchain database of all nodes that hear about it.

It's fine, more or less, and it's short. Problem is, that 60% of the above mentioned is not clear for most of the people. And if you are in the elevator, the loudest person would be the one who won't uderstand the 2nd or 3rd sentence and will shout BS, and you won't have the chance to finish.
However, this is useful if you are presenting something in connection with this subject, and someone asks you what is blockchain, in this case this can be your quick answer to that question.
