A distributed ledger that records transactions sequentially into blocks and links these blocks in a chain. Each block has a cryptographically secured “hash” that links it to the previous block. In order to add a new block to the chain, the consensus mechanism requires miners to solve a cryptographic problem. The solution has to be verified by all the other participants in the network. If the majority of the nodes verify that the solution is correct, the new block is added to the blockchain and all copies of the distributed ledger are updated.
Mining requires vast resources of computing power and electricity, so this imposes substantial costs on any attempt to manipulate a blockchain’s historical record. In order for a hacker to make a fraudulent transaction on the Blockchain, he would need to gain control of a majority of the nodes to gain consensus.

Welcome to PrepNuggets
Hey visitor,
Are you a CFA Level I candidate, or someone who is exploring taking the CFA exam? Four years ago, I was in your shoes. I am a Computer Engineering graduate and have been working as an engineer all my life. Having developed a keen interest in finance, I decided on a career switch to the finance field and enrolled into the CFA program at the same time.
Was it tough? You bet!
Adjusting to the drastic career change was tough. I naturally neglected the preparation for my Level I exam in June 2014. It was not until the middle of March 2014 that I realized I only had a little more than 2 months to the exam. To compound my problems, I basically did not have a preparation strategy. Having no background in finance at all, I tried very hard to read the curriculum from cover to cover, but eventually that fell flat. I can still recall the number of times I dozed off while studying, or just going back and forth trying to understand even the simplest concept. My mind simply could not keep up after a hard day at work.
Does all these sound familiar to you? Well, take heart. No matter how bleak it seems, at least sit for the exam and treat it as a learning experience. That was basically my attitude as I burrowed through my exam prep with toil and stress. By God’s grace, I did pass my Level I exam in June 2014. It was an experience I would not want to revisit though.
Tweaking the approach
For the Level II exam, I endeavoured not to repeat the mistakes I made. Based on the Pareto 80/20 principle, I learnt to extract the most essential bits from the curriculum enough to give me that 80% result to pass. Being a visual learner, I took notes and summaries in pictorial form. Instead of reserving huge segments of time to study, I carved out pockets of time to learn and practise – accommodating to my full-time job. I managed to pass my Level II and Level III exams consecutively with considerably less effort and stress than when I did my level I.
