    Testnet stops responding when downloading specific block

    @strophy thanks for your support, appreciated. I have tried in a super fast connection with my Mac and had the similar issue. I switched to my linux laptop right now, testnet is about to get totally synced having gone away from the previous problem except from the fact that it seems to by...

    InstantSend Double Spend in Theory vS in Practice

    I read the code, what I don't get is what information is disclosed to a masternode owner about other masternodes and how an attacker could recognise one of his other masternodes (say he controls 2) while participating in the quorum.

    Testnet stops responding when downloading specific block

    I am running 12.2.3 Mac OSX version. Can you provide instructions on how to compile the develop branch in the link?

    Testnet stops responding when downloading specific block

    I have this issue 3-4 days now, and it keeps repeating itself. So I start the testnet and blocks are downloading, but when it goes to a specific block it stops responding. Can someone tell me what to do? This is the last 50 lines from my testnet3/debug.log: 2018-04-03 18:13:13...

    InstantSend Double Spend in Theory vS in Practice

    I still don't understand something and pleaser answer this specifically: in an ecosystem of 4600 master nodes, an attacker who controls 6 masternodes, how can he know for sure that his 6 masternodes are going to be included in those 10? How can he know the rest of 4594 in such detail so that he...

    InstantSend Double Spend in Theory vS in Practice

    I am reading the code of instantx.cpp and I am confused on how an adversary can double spend. What confuses me is the fact in my understanding, a master node is voting yes/no on "if a particular input was previously spent" without knowing who else is participating in the quorum. By this, there...

    TestNet OSX app does not responding

    This happened 3 consecutive times whenever ~55K blocks were left during the first time that testnet was launched and when doing right click on the icon and clicking on force quit, when restarted kept doing the same thing. What I did was to do rm -r testnet3 and recreate it by restarting the app...

    Masternodes Capabilities as network attacker

    I am confused on the capabilities that a masternode owner might have when it comes to instantSent or privateSend. 1) I want to know if is possible to setup the masternode configuration file in a way that you write code for example so that you can do anything. 2) If is possible to add customised...
