9. What are futures?
Futures contracts allow investors to agree to buy a certain amount of a commodity, bond or share at a specific price at a designated time in the future, hence the name. It means investors can bet on whether they believe a particular commodity – in this case bitcoin – will rise or fall by a specified future date. They are generally used in commodity markets to hedge against major fluctuations in prices, such as unexpected weather conditions hitting crops. But they are also well established in equity markets, with trading on individual companies and indices such as the FTSE 100 and S&P 500. There are risks, mainly when investors use debt to finance their futures speculation and their bet goes the wrong way. Source:

18. A blockchain, originally block chain, is a continuously growing list of records, called blocks, which are linked and secured using cryptography.
Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data.
Harvard Business Review defines it as "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 validating new blocks.
Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
