Blockchain – what is it?
Cryptographer David Chaum first proposed a blockchain-like protocol in his 1982 dissertation "Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups Further work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta. They wanted to implement a system wherein document timestamps could not be tampered with. In 1992, Haber, Stornetta, and Dave Bayer incorporated Merkle trees into the design, which improved its efficiency by allowing several document certificates to be collected into one block. Under their company Surety, their document certificate hashes have been published in The New York Times every week since 1995.
The first decentralized blockchain was conceptualized by a person (or group of people) known as Satoshi Nakamoto in 2008. Nakamoto improved the design in an important way using a Hashcash-like method to timestamp blocks without requiring them to be signed by a trusted party and introducing a difficulty parameter to stabilize the rate at which blocks are added to the chain. The design was implemented the following year by Nakamoto as a core component of the cryptocurrency bitcoin, where it serves as the public ledger for all transactions on the network.

10 Questions You Must Ask When Considering Universities
Applying to any college or university isn't easy, and it's important that you ask the right questions to ensure that you are making the best decision for you. Below, I have composed a list of what I think are the most important aspects of university to contemplate in order to make the right decision, and who you should look to for advice.
1. What course is right for me?
It's no surprise that the most important questions you should be asking are in regards to the course(s) you intend on studying. You will want to think about the course content (what the modules include), where this course could lead you, how it works alongside any other courses you plan on taking, and the workload.
Prospectuses will include the most vital information, but it is important that you speak to current and past students of this course, as well as the professors. It is also important to remember that the course content can depend on the university, and modules may differ from place to place, so it is best that you check out each university offering this course to ensure that it will be ideal for you.
2. What is the accommodation and travel like?
You may have found a college that offers everything you want in way of courses. However, if it is not local, then you will be considering accommodation. You will spend a large amount of time in your student house or dorm, so making sure that you select the best base is a must. Whether it be shared housing or catered student halls, it is likely that finances will be at the forefront of your mind. While student and maintenance loans cover some bills, it is likely that you will be paying monthly/weekly out of your own pocket. In order to get the best deal, look into student accommodation well in advance-consider food bills, electricity ETC if you are renting, and the bathroom situation if you are lodging in student halls.
On the other hand, if you are fortunate to have found a university local to you, you need to start considering how you will be traveling there each day. Will it be by train? If so, how much will that cost you per semester—and can you get a student discount? By bus? Once again, how much will this cost and where are the bus stops situated? Most colleges will be within walking distance of a train station or bus stop, but how safe is it to walk, especially at night? If you are driving yourself, how much will you be paying in petrol? Where can you park, if not on campus?
3. What about finance?
It is best to start looking into student finance as soon as possible. While course prices stay similar no matter where you go, accommodation can be more or less expensive depending on the university and area. Most are eligible for a student loan, and this can cover most—if not all—of your course fees. Maintenance loans can be used to cover accommodation prices, as well as living costs. To check how much you're eligible for, you can set up a meeting with a career advisor, or look online.
Scholarships are invaluable when it comes to financing your studies, so looking into what scholarships each school has to offer is a great way to deduct the overall costs. If you are from a disadvantaged area, or have a unique circumstance, you may be able to access extra funding! Make sure you look into every option. Student loans, grants, and maintenance loans are unlikely to cover all of your bills, especially if you are regularly going out with friends, so finding a part-time job can mean you have that extra money to experience college in all of its glory.
