A basic blockchain crash course
What is the blockchain?
The blockchain is a digitized, decentralized, public ledger of all cryptocurrency transactions. Constantly growing as ‘completed’ blocks (the most recent transactions) are recorded and added to it in chronological order, it allows market participants to keep track of digital currency transactions without central recordkeeping. Each node (a computer connected to the network) gets a copy of the blockchain, which is downloaded automatically. (For more information see: https://en.wikipedia.org/wiki/Blockchain)
What are smart contracts?
Smart contracts help you exchange money, property, shares, or anything of value in a transparent, conflict-free way while avoiding the services of a middleman. The best way to describe smart contracts is to compare the technology to a vending machine. Ordinarily, you would go to a lawyer or a notary, pay them, and wait while you get the document. With smart contracts, you simply drop a bitcoin into the vending machine (i.e. ledger), and your escrow, driver’s license, or whatever drops into your account. More so, smart contracts not only define the rules and penalties around an agreement in the same way that a traditional contract does, but also automatically executes and enforces those obligations.

What are cryptocurrencies?
Cryptocurrencies are digital currencies (also known as “coins” or “tokens”) for which encryption techniques are used to regulate their use. Unlike fiat currencies (like USD or YEN) cryptocurrencies are not regulated or controlled by any bank, government or centralized financial authorities.
Where and how do I buy Bitcoin or Ethereum?
The safest and most commonly used way for new users to purchase any sort of cryptocurrency coins is through a cryptocurrency exchange site. REALISTO recommends GDAX, Kraken or Bitstamp, which all support fiat money (official currency) transactions. Keep in mind that the account verification process for new users of these exchanges may take up to four days.
Where and how do I obtain a cryptocurrency wallet?
To participate in the ICO, you will need an ERC-20 wallet (Ethereum standard). REALISTO recommends myetherwallet.com. Pay attention to the security-related instructions on that website, and keep in mind the general safety rules for doing business on the internet. You’ll find that there is just as much due diligence involved as there is with regular internet banking. After all, this is your money we’re talking about here.

What is an ICO?
The term Initial Coin Offering (ICO) the process in which a company issues a new cryptocurrency or token to investors in exchange for Bitcoin or Ethereum. Thus crowdfunding their venture while giving investors a stake in it via the token. The value of the newly generated token is closely linked to the success and progess of the underlying venture.
