Thought Iā€™d create a thread to post articles of interest relating to the different consensus mechanisms. I find it interesting reading/learning varying opinions on the subject.
For example, there is an article linked below where David Schwartz (Ripple CTO) shares his view on why Bitcoins Proof of work protocol is unsafe.

Feel free to ignore the XRP price prediction section :grin:
