Death's Halt (By Liu Cixin) As Well As The Swordholder Problem
This is the final mass inward Liu Cixin's Remembrance of Earth's Past trilogy. I had written reviews for the Three Body Problem together with Dark Forest before. So for completeness sake, I write my impressions close this mass equally well. This fourth dimension I endeavor non to speak much close the plot, together with endeavor to choke along this spoiler-free.
This mass is epic, inward damage of the infinite distance together with timeline it covers. It is awe-inspiring inward that vastness inward infinite together with fourth dimension sense, together with makes you lot cry back at the universal scale. This mass feels much to a greater extent than hardcore sci-fi than the previous ii books, together with less believable than them. The mass also feels rushed inward character/plot evolution (definitely non length) compared to the previous ii books. But all inward all, it is a rattling captivating scientific discipline fiction together with I couldn't halt thinking close it fifty-fifty i calendar week after finishing the book.
The mass withal has a rattling cynical together with rattling pessimistic thought of human nature (as good equally alien nature). The universe is a night forest, where everyone tries to destination off each other. Everything is bleak, life is meaningless, pointless, together with worthless.
On the other hand, the mass made me rattling optimistic close the potential advances inward science. The description of iv dimensional infinite is rattling rich inward visualizations. The brainstorming the mass induces on what things are possible if you lot tin manipulate the 3 dimensional infinite from iv dimensional infinite is inspirational. The potential behind the curved cast drive technology scientific discipline (manipulating/changing physical laws) is also amazing to dream about.
One of my primary annoyances alongside the mass is the weak grapheme evolution together with naivete inward sex dynamics inward the book. Cheng Xin, the primary grapheme inward the story, is portrayed equally a weakling. She is rattling smart (an aerospace engineer) but she is weak together with fallible. Like inward the master copy sin, she is blamed for the autumn of man, non in i trial but several times. I was aghast at how absurd this portrayal was, together with I couldn't halt myself screaming dorsum to the audio-book at several places.
Unfortunately Liu Cixin's women characters possess got been all i dimensional. Luo Ji's married adult woman was also that way. In the Dark Forest, Luo Ji has created a perfect adult woman inward his imagination: a rattling submissive, rattling gentle, soft-spoken, geisha similar woman. The worse business office is that after that Da Shi had searched Cathay to honor the adult woman that fits the description. It was cringe-worthy to read close how one-dimensional this grapheme was inward the book.
Those existence said, I desire to emphasize in i trial to a greater extent than that Cixin Liu is a rattling talented floor teller. (I am rattling much impressed yesteryear the inventiveness inward the stories told from the rima oris of Yun Tianming together with the technological clues hidden inward these stories.) I recommend the serial strongly to all science-fiction readers. I also desire to recognize the hardwork together with talent of the Ken Liu for doing a superb project inward translating the books to English. It looks similar he has taken a lot of initiatory together with made creative improvements inward the translation rather than doing a straightforward translation.
Liu Cixin has a programming background. He should possess got realized that this trust work is meliorate handled yesteryear using a Byzantine fault-tolerant consensus protocol. Instead of i person, conduct seven people to human activeness equally swordholders together with this organisation volition tolerate 2 Byzantine swordholders (because N>3*F).
If nosotros brand the supposition that the swordholders don't counsel alongside each other together with each makes a determination on a definite together with right input provided to them, it may last possible to brand the organisation move alongside N=2F+1 nodes, tolerating to a greater extent than faulty nodes. In that case, but a multisignature solution (with F+1 signatures) could work. (The input is whether the Trisolarans started an assail on Earth. This assumes the input is definite/decisive together with binary together with it volition last visible to the nodes non through other nodes, but through the environment, media, newsreport, together with sensors. And this assumes that for the nonfaulty nodes the input is non faked equally inward Truman show.)
Yes, this is besides many assumptions, then a counsel based solution amid nodes, together with thus a Byzantine fault-tolerant protocol alongside N=3F+1, seems to last to a greater extent than appropriate.
Of course, Liu Cixin used the swordholder seat for dramatic termination inward the novel, but I am a technical person, together with I can't larn over the fact that the people of 3 centuries later on would last then ignorant of to a greater extent than suitable solutions to the problem.
This brings me dorsum to our time... Is the nuclear push clit holder seat inward our fourth dimension withal a unmarried trusted someone position? (Related concept: Dead hand) Do nosotros trust a president this much to give him this responsibility? Isn't it fourth dimension to found a Byzantine fault-tolerant solution to solve this problem?

The swordholder problem
The outset business office of the mass describes the swordholder position, which is classify of a usual devastation button-holder duty. Initially Luo Ji was tasked equally the swordholder. But the work alongside the swordholder seat is that this puts besides much trust inward i person. One someone becomes responsible for life-death determination of ii worlds, the footing together with trisolaris.Liu Cixin has a programming background. He should possess got realized that this trust work is meliorate handled yesteryear using a Byzantine fault-tolerant consensus protocol. Instead of i person, conduct seven people to human activeness equally swordholders together with this organisation volition tolerate 2 Byzantine swordholders (because N>3*F).
