How to develop the bitcoin technology Cornell University
We squeezed into a small room filled with black frame of the giant network. The fan and the computer sound intertwined, breaking the dull air.
In this noisy buzz, Cornell University doctoral candidate AdemEfeGencer voice almost drowned, he explained that the monotonous frame represents Connell in the name of science for the realization of building a global bitcoin network this ambition was to.
He pointed out that these servers accounted for approximately more than 1200 nodes of the bitcoin test bench for half. The other in the basement.
The project is called “micro world”, named after the stereo model inspired by the real world tourist attractions. Just, “micro world” constructed not a toy car and building models, but bitcoin network node.
“I don’t think there are other institutions to have such a big computer cluster.”
The most obviously is the question of what they do with these large and complex nodes? Gencer is a member of the IC3, IC3 of Cornell University is a specialized research digital currency institutions, he is studying the whole system of different rules or opposition environment will likely react.
The team to carry out the plan in the “small” network.
He said: “we want to extend it, the ultimate goal is to make it like bitcoin as large public network.”
You know, it takes a lot of nodes. According to the statistics of the bitcoin network Bitnodes, there are nearly 7000 nodes, including non monitoring nodes (but do not accept new connections with other nodes), the total number of more than 50000.
By pairing with the test bench, the Cornell University has established a framework by Gencer as the protocol compared to the more “principle”, the framework includes measurement indicators such as delay and information transmission system in the center of the adaptability etc..
“Micro world” to be able to run any client or more innovative protocols, such as Bitcoin-NG, which radically redesigned bitcoin, to extend it to support more affairs.
He said: “as long as the client to our system, we can run.”
Gencer believes that this measure can affect the network, and now bitcoin for decision-making system — some have questioned the effect.
Gencer joked: “the bitcoin community there is another popular method that is discussed.” That often Twitter and Reddit and other social media platform of dialogue.
Other people think that, because the technology in its early stages, this simulation is not perfect, it is difficult to figure out where the effect.
However, the “micro world” is not the only IC3 bitcoin project.
Last year’s launch of the Falcon network is a public agency chain of the more noteworthy attempt to help the bitcoin network to the center.
The composition of the 10 nodes of the network by the Cornell University has, provides a “fast track”, the miners and various size pool can quickly send and receive block.
Cornell University graduate student SoumyaBasu said in the description of the system: “this makes the environment more fair competition among miners.”
So far, Falcon provides second miners for faster transfer block on the network relay network and widely acclaimed. Previously only one: FIBER, has been called the bitcoin relay network.
Basu stressed that the choice of diversification is beneficial for miners.
“If there is only one relay network, and for some reason (maintenance problems, attack etc.) fault occurs, then the time will be slower than the block transmission.”
The director of IC3 EminG nSirer agree with this view, he believes that with the implementation of the increase, users do not have to trust only one open source network and the volunteer team.
The real impact
Again, the project is not only in order to improve the efficiency.
In the interview, Basu said, a variety of options (such as Falcon) can help the bitcoin better by minimizing the trust to achieve goals.
“The relay network has certain rights. If a relay network transmission speed of some blocks to determine more slowly than other blocks, then you can make such as selfish mining such attacks more easily.”
Here, Basu also suggested that the game theory behind Cornell University bitcoin is very interested in.
He said: “if you have to transfer multiple relay network block, then slow down the block transmission of a particular miners benefit is very limited.”
Basu, deputy director of the Sirer and IC3 IttayEyal are the promoters of the project, they have also developed a new thing called “cut through routing”, has now been included in the FIBER network, improve the network transmission speed block.
Expand the scope of
Today, Cornell University’s “micro world” has many famous bitcoin network simulation, but there are many others, including a Technical University of the Swiss Federal Institute of technology in Zurich open.
However, the Cornell University is also trying to maintain the leading position through other significant block chain and digital currency project.
In order to achieve this goal, Gencer said the Cornell University is working on a test bench like current run on the same infrastructure on the same Ethernet fang.
“To our knowledge, there is no human etheric Fang to try it.”
