Violation of immutability while purging of private data from fabric ledger?

Violation of immutability while purging of private data from fabric ledger?

If private data has a lifespan, and it is purged after this lifespan. Doesn't this violate the fundamental principle of immutability and the core idea of the blockchain. I know that the hash of these private data is stored in the ledger but if a data deletion is occurring then it seems that the core

Tor proxy on Electrum, what does Port: 9150 and 9050 mean?

Tor proxy on Electrum, what does Port: 9150 and 9050 mean? The first time that i installed Electrum i navigated to Tools->Network->Proxy i saw there a checkbox "Use Tor proxy on port 9050", i had a problem with my OS so i had to reinstall my OS, Electrum and Tor, and now instead of "port 9050" it's "port 9150". I think that it's because i'm using the Tor Bundle, as said on this electrum docs , downloaded from here: https://www.torproject.org/projects/torbrowser.html.en#linux i want to know what is the difference between the port "9050" and "9150". And if i'm fine using the "9150". https://ift.tt/2T0EvmY

How to discover startup flags or command-line options for bitcoind?

How to discover startup flags or command-line options for bitcoind? I'd like to query the Bitcoin daemon (bitcoind) to find out what startup flags (command-line options) were sent to it on startup (or the current state if it has changed, e.g. -server=0/1 changing). For example, I may want to know if -addresstype, -disablewallet, -rescan, or -uacomment=<cmt> or some other flag has been set. Or for Namecoin, it would be very useful to know if -namehistory has been set. Is there an RPC or any other method to find out? Or, to ask the question a different way... src/bitcoind.cpp's bool AppInit(int argc, char* argv[]) method calls ParseParameters(argc, argv);, which is in src/util.cpp. In src/util.cpp we have: map<string, string> mapArgs; static map<string, vector<string> > _mapMultiArgs; const map<string, vector<string> >& mapMultiArgs = _mapMultiArgs; To store flags/options/args. I'd basically just like to get whatever is in tho...

Can we see Blockchain decentralized data like a mathematical duality or morphisms between representations?

Can we see Blockchain decentralized data like a mathematical duality or morphisms between representations? I prefer to think BLOCKChain in mathematic spaces formulation because we need to understand what is in mathematic terms this 'de-centralization' before. I find this what is decentralization and Wiki-decentralized blockchain My idea is that 'de-centralization' it is not as it appears so I start to use Category Theory to un-lock this 'blocks concept' because there is something that does not come back to me in all this 'inviolability' because we talk about just a simply P2P way (nodes, data,transactions..) 1 propagation 2 over a network 3 but the underlying layer is to the extend that this propagation is represented like a math object and now is useful also to talk about Feynman Propagator of a Scalar Field 1 : like algebraic varieties or manifolds 2 : in this case we talk or Action Functional or about Group Action 3 : This remember in math s...
