    14  * `libp2p` database tips：
    15  
    16      * when `libp2p` store `key-value`, it will make `key` to `hash` of `key` and the `key` + `value` + `timestamp` will be `value`.
    17  
    18      * when `libp2p` store `key-value`, the `key` should start with `\`.
    19  
    20  # develop tips.
    21  
    22  * when get the url of bootnodes，we need change it to node，the code is at `cmd/utils/flags.go#L610`
    23  
    24  ```go
    25  url = "vnode://123b13dfdb555c69290acf510f2e1c00b9d31a917d8c9e7cf8216812da10caffd6e242879bbae43aa09c3bd2ef49c45999bb0c502d38d8c8f9d60287f2220c0c@127.0.0.1:30301"
    26  
    27  node, err := discover.ParseNode(url)
    28  ```
    29  
    30  # VNT starts
    31  
    32  ## `bootnode` start
    33  
    34  ```bash
    35  $ cd bootnode-dir
    36  $ bootnode -genkey=node.key
    37  $ bootnode -nodekey=node.key
    38  ```
    39  
    40  > the database is ：`bootnode -datadir="./" -nodekey=node.key`。
    41  
    42  ## `membernode` starts 
    43  
    44  > ATTENTION：
    45  > * `datadir` can't be too long。
    46  > * `vntbootnode` is `vnt's``bootnodeURL`
    47  > * `port` is `vntnode's` port
    48  
    49  ```bash
    50  $ gvnt --datadir=./datadir1 --vntbootnode=/ip4/127.0.0.1/tcp/30301/ipfs/QmW1zhpCHrfoyXjWRkJMaTgtfy7BiqhZfHajgK3Xnysoxx --port 30306
    51  ```
    52  
    53  producers node starts
    54  
    55  ```bash
    56  $ gvnt account new --datadir ./datadir2
    57  
    58  $ gvnt --datadir=./datadir2 --vntbootnode=/ip4/127.0.0.1/tcp/30301/ipfs/QmW1zhpCHrfoyXjWRkJMaTgtfy7BiqhZfHajgK3Xnysoxx --produce --producerthreads=1 --coinbase=0xf6f5038a406a7fe78229a80850ca8ed42fe03bfd --port 30307

    60  
    61  now，`vntdb` is support `--datadir` tag
