Blockchainserver implementation.

BlockChainServer

The BlockChainServer application has been tested on windows and mac. It has not been tested on Linux, but it will probably work. The server uses 2 ports. The 8080 port is for the API interface and the 8081 is for communicating between servers.

Compiling

On unix

mkdir build
cd build
cmake ..
make
make install

On windows You can create VS files using cmake-gui.

Runnig

You can use --http-port to change the default HTTP port and --tcp-port to change the TCP port. Example usage:

./blockchainserver --tcp-port 81 --http-port 80

API

For getting help

http://127.0.0.1:8080/help 

/createblock

It is using to create a new block.

curl -X POST -d "Test Data" http://127.0.0.1:8080/createblock

{"Status":true,"Index":2}

/getblock

Get block information via index.

curl -X POST -d "2" http://127.0.0.1:8080/getblock

{"Status":true,"Data":"VGVzdCBEYXRh"}

Data is encoded in Base64.

/totalblocks

Total blocks count.

curl http://127.0.0.1:8080/totalblocks

{"Status":true,"TotalBlock":2}

/blocks

Fetch all blocks.

curl http://127.0.0.1:8080/blocks

{"Status":true,"Blocks":[{"Index":1,"Hash":"d9b5d942a14db7a408328b178bfb531b508b322a08264cbf189c008947512634","PreviousHash":"8bb60170a7a13686c3c651dac9038ce96eed1ff208cd5e29b4b16bbfec5c9c20","TimeStamp":1508090809,"Nonce":0,"Data":"R2VuZXNpcyBibG9jaw=="},{"Index":2,"Hash":"35da1352558b78801f3ed2c91520ab2bffac7fceaf3338b2c767f2a463aab3ec","PreviousHash":"d9b5d942a14db7a408328b178bfb531b508b322a08264cbf189c008947512634","TimeStamp":1508236436,"Nonce":0,"Data":"VGVzdCBEYXRh"}]}

/addnode

Add new blockchain server.

curl -X POST -d "127.0.0.1:9787" http://127.0.0.1:8080/addnode

{"Status":true,"Message":"Node will be added."}

Synchronization could take a time.

/nodes

Connected node list.

curl http://127.0.0.1:8080/nodes

{"Status":true,"Nodes":["127.0.0.1:9787"]}

/removenode

Disconnect from remote node.

curl -X POST -d "127.0.0.1:9787" http://127.0.0.1:8080/removenode

{"Status":true}

/sync

The system automatically synchronize other servers continuously but can be used if you want to trigger this manually.

curl -X POST -d "127.0.0.1:9787" http://127.0.0.1:8080/removenode

{"Status":true}

/validate

It is used to check the validity of block information.

curl -X POST -d "{\"Index\":2,\"Hash\":\"35da1352558b78801f3ed2c91520ab2bffac7fceaf3338b2c767f2a463aab3ec\",\"PreviousHash\":\"d9b5d942a14db7a408328b178bfb531b508b322a08264cbf189c008947512634\",\"TimeStamp\":1508236436,\"Nonce\":0}" http://127.0.0.1:8080/validate

{"Status":true}
