Imagine such a scene: anywhere in the world of the future use of the currency, at this time because the blockade of country X X (i.e., for some reason, the external network impassability), at this point, the X instead COINS should be can continue to run normally, the world (except country X) COINS can also will continue to run, but, after the blockade lifted (network recovery), if you don't rely on artificially modified block information (make all nodes information synchronization), X the blockade during the deal should not be recognised (unless the blockade during X instead to deal more than the rest of the world),
Whether, then, would think X countries during the period of block trading is invalid, then these transactions will not record in the block?

Similar to the etheric rollback, bifurcate,The third concept is bifurcate, fork COINS to pow, principle is to hash collision, so in the process, basically there will be a few people at the same time, achieve the result of the hash collision,
Is not the ultimate agreement so pow, once appear, consensus bifurcate, COINS principle is the longest chain of winning, so short of bifurcate, would be to give up, but in theory, if a person, decided to is the short bifurcate continues, then two real chain points out, in fact, of course, not everyone is so do,

First of all, thank you for your answer!Secondly, I have to ask the following questions,
If a region as a node X, then the problem is not solved, that is, the area of all trades is equal to the node X trading,
Of course, there is a premise:
At some point according to certain algorithm (for example, according to the delay of sending broadcast after receiving reply,,), the formation of multiple regions, and each area must have a trusted node (for all transactions) storage area,

Currency is the earliest known block chain, in the purpose of this cookie design is completely decentralized, so didn't you say this concept,Block chain technology is now more than it, the technical route, fabric, POW, XBFT, XPOS several, according to the node access permissions as divided into chain (BFT, POS, fabric, etc.) and the licensing chain (POW), as well as the advantages and disadvantages of each have a suitable scene, for the distinction between nodes, each is different,
Personal think probably understand technical route, but to understand a little as the underlying choice, personal feel or focus on application development and middleware is appropriate,
Thinking and block chain, recently more heat is assets on the chain, exchange (regular trading for beef and mutton, and the electronic assets and futures, tourism products, such as assets, our community is to be decentralized trading),

Like many etheric community innovation is very rich, for good or floating in the sky, see the spinach and private chain, do chain alliance, and chain the most simple fall to the ground, there are strong than,CodePudding user response:
Say is very reasonable, thank you!CodePudding user response:
Technology route, the 2019-09-11 weeks of sand: Libra can return to the international chain blocks development of, in terms of practical application, and financial related technical route to roughly five, the first is the R3 alliance, this is the first to make to, no card, no block, when used by Goldman, jpmorgan has successively withdrew, recently has been silent, the second is IBM with Fabric, this route is no certificate, both at home and abroad to use it more, such as the BAT, etc., and the third is IBM, he has done with a star (Stellar) reached a strategic cooperation, use block chain to realize the legal tender of cross-border payments, exchange, article 4 of the application to the enterprise is based on Ethernet fang, is the main application of jpmorgan's certificate, article 5 of the well through technology route in August 2014, when the goal is to "One Belt And One Road" cross-border yuan settlement as a supplement, the underlying consensus is to RBFT, more interestingly, the Libra in the underlying agreement with facebook, the technical architecture or establish ecological way is 80% - 90% of the similarity, Libra, the much immediately signed more than 20 large global partners to form alliances; But in the concrete implementation, likely to encounter practical difficulties and problems of the current may not fully understand,
