Framework for designing Blockchain (in combination with secure multi-party computation)

Framework for designing Blockchain (in combination with secure multi-party computation)

I'm looking for a framework where I can build my own blockchain. In my case I wan't to combine the blockchain with secure multi-party computation algorithm. Means that two or more parties want to exchange data without revealing the input data...

are there any good framework you can recommend? (Free or academic access etc.) I found Openchain and Nstratis... maybe there are better ones?

Thanks in advance.

sendrawtransaction and txn-mempool-conflict

sendrawtransaction and txn-mempool-conflict When i sendrawtransaction to bitcoind, i get error (exceptions) 18: txn-mempool-conflict (use Bitcoin JSON-RPC denpamusic/php-bitcoinrpc ) But the transaction is sent to the network and is subsequently confirmed. Example one decoded transaction : https://jsfiddle.net/rn58a4j6/ then i send this transaction: 94ec12fc463230b4285a29b047608627c05572a4c6eabe6688a201ce49ae72f7 https://ift.tt/2MY2KP0

couldn't connect to server: EOF reached (code 1)

couldn't connect to server: EOF reached (code 1) I'm running a full node on my raspberry pi3. I try to do a simple command such as bitcoin-cli getblockchaininfo but I always get this error: error: couldn't connect to server: EOF reached (code 1) (make sure server is running and you are connecting to the correct RPC port) My bitcoin.conf file looks like this: Bitcoind options server=1 daemon=1 reindex-chainstate=1 reindex=1 txindex=1 disablewallet=1 listenonion=0 Connection settings rpcuser= * rpcpassword=* rpcport=8332 rpcallowip=127.0.0.1 rpcthreads=10 I also tried to get a command with "bitcoin-cli -rpcuser: * - rpcpassword=* -rpcportt8332 getblockchaininfo". But this also didn't work. Does someone has some advice or experience with this error? https://ift.tt/2D82TLW
