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

/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"}]}

{"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
