По-скоро няма шанс да разбереш, че ти проследяват транзакциите

(8/2200)*(7/2219)*(6/2218)*(5/2217)*(4/2216)*(3/2215)*(2/2214)*(1/2213)
Хайде, смятай.. шанса е много пъти по-малък отколкото шанса за 6-ца от ТОТО-то..

Masternode Blinding
Recently a paper by 3 researches at Saarland University came out describing a new technique, while there are some serious problems with the approach they take, the concept of blinding the users they use is novel. In CoinShuffle, each output is sent to the next peer in a circle, one at a time. The new peer adds an output, shuffles and then sends the list again. We can do this and actually improve upon it.
To implement blinding, each user would connect to one completely random masternode and say "Send masternode X this output/value for mix N" and pass a single output. That output would be passed to the leading masternode. It would take access to all masternodes used to know who did what, which is as solid as M rounds mathematically (M = number of outputs). This is great because all users can submit all inputs at once. So it's super fast compared to CoinShuffle and even more secure.
Decentralization of the masternode payment system
Currently, there is a node that signs a message for each block and says which masternode should be paid for that specific block. As many of our users know, the centralized reference node was a temporary solution to the problem of enforcing masternode payments. Miners use this when creating the block to ensure they comply, if a miner tries to cheat the system, the block will be rejected by the network. This is a great solution temporarily, but isn’t decentralized enough.
To explain the new completely decentralized strategy, first we have to explain exactly how masternodes work. When a masternode starts, it relays a message called the “masternode election entry”. This puts the masternode into a list on all clients on the network and allows them to be used by all of the clients on the network. Every few minutes, these masternodes ping the network saying they’re still alive and allowing them to earn interest payments.
To decentralize this system, we propose a new system we’ll call “Masternode mining”. This simply means that when miners receive a new “masternode election entry” and solve a block, they will append the masternode to the block. Each block can contain up to 10 masternode list changes. So by following the normal progression of the blockchain, you will be able to compile a list of all known masternodes. This system is also highly resistant to attack and the same list can be compiled by any client on the network.
For example:
Block 1: Add mn1, mn2, mn3
Block 2: Add mn4, mn5
Block 3: Remove mn2 //mn2 fell off the network
-- currently the masternode list contains mn1, mn3, mn4, mn5
Block 4: Add mn6, mn7
Block 5: Add mn2 //mn2 came back
-- example attack: --
Block 6: Remove mn1, mn2, mn3, mn4, mn5, mn6 //miner owns masternode 7, wants control of the network
Block 7: Add mn1, mn2, mn3, mn4, mn5, mn6
In this case a majority of mining power is required to control the masternode list. If a miner has enough computing power to alter the masternode list, they will also have enough power to double spend with a 51% attack. Therefore this is the safest solution to decentralizing the payment.
