I am holding a marble, which I give to you. To fully understand what happened during that transaction, let’s look at it more closely. I took a marble that I owned, and then physically put it in your possession. You and I both saw it happen, and we didn’t need anyone else to confirm that it had happened.That marble is now yours. I don’t have it anymore and cannot give you another as I have no more. I no longer own the marble that I gave you and now that you own the marble you are free to keep it, or give it away to someone else.Now, imagine I have a digital marble. I own this digital marble and again choose to give it to you. Now you have the digital marble, but because it is digital, how do you know I still don’t have it as well? Or that I haven’t given it to other people before you?To solve this, how about we let a third party keep track of the transactions of digital marbles. We will give them a full ledger of who has what, and when they got them, and who they got them from.Now, this works in the physical space but in the digital space it creates a big problem. You can’t create a marble out of nothing in the physical world, but in the digital world one could theoretically create as many as you wanted.So the third party in charge of the ledger could give themselves a many digital marbles as they wanted. Luckily we can prevent this from happening by not just giving one person control of the ledger.Giving everyone access to the ledger that lists every transaction of marbles ever made makes it impossible to cheat the system. With every transaction recorded, we all know how many marbles each person has, when they got them and who from.Now we still need someone to confirm that I actually have that digital marble before I give it to you, but instead of having one third party there to witness it, let’s have a few. Then for those that help check and update the ledger, we will give a few digital marbles for their troubles. This is actually the only way that more digital marbles can be made.Because of the public nature of the ledger and the fact that it is constantly policed by those who use it, those digital marbles behave exactly like it’s physical counterpart.This is a simple representation of the bitcoin protocol, where the digital marbles represent Bitcoins and the ledger is Blockchain. In the next installment I will discuss how this technology has impacted the financial world, as well as potential uses.last_img read more

first_imgOn a Friday afternoon, Jessica Nathania, a senior majoring in human biology, can be found at California Hospital Medical Center.“The best thing about Remedy is when, after a performance, a patient or hospital member will come up and let us know how much they really appreciated it,” Nathania said in an email to the Daily Trojan. “This happens more often than I thought it would, too.”Nathania is the co-president of Remedy Through Music, a USC student-run group committed to performing therapeutic music for patients in medically underserved areas of Los Angeles.“Remedy Through Music is a service organization aimed to help mitigate the pain and suffering of patients in hospitals, residents in assisted living homes and at-risk children through the use of music,” Remedy Through Music Vice President Shamit Bhatia said in an email to the Daily Trojan. “Remedy strives to empower USC students to use their musical talents and help out the local community around USC by providing [therapy] to all. Music has no specific language and is therefore universal.”The organization usually has one performance a week, often on a Friday afternoon or Saturday morning with an occasional performance on Sunday. These performances generally take place at medical care centers, convalescent homes or after school centers for children. Students are also encouraged to play for patients in a more intimate setting, such as their individual rooms.In addition to weekly performances, the group organizes a more formal recital on a semester basis at Kingsley Manor where students are given the opportunity to perform more polished pieces.Members perform any genre of music, ranging from Bach to the Beatles.Most students in Remedy Through Music enjoy using music as a means to express themselves while also appreciating medicine and its positive influence on society. Many students who take part in the organization are majoring in science-related fields or are pursuing the pre-health track at USC.Co-President Brian Zukotynski said he initially joined his freshman year to combine his two passions: music and medicine.“Beyond weekly performance opportunities, Remedy provides me the chance to use the musical skills I have built up over most of my life to give back to my community and fellow students,” Zukotynkski said. “Remedy’s goal is to bring the joy of music to anyone who wants to listen, but primarily for the sick  and elderly.”last_img read more

first_imgFORT ST. JOHN, B.C. – To say game three tonight between the Fort St. John Flyers and Grimshaw Huskies is huge would be an understatement. Down 2-0 in the series the Flyers can either find themselves down three games, or they can get back to within one with two of the next three tilts after tonight being back in Fort St. John.Despite scoring early in game two the Flyers found it a struggle to get much going offensively as both clubs were more committed to defence after a total of 13 goals were scored in the series opener.After tonight’s contest game four will be at the North Peace Arena Saturday night at 8:30.- Advertisement –last_img read more
