Introduction

P.S.

• local update: git pull vnt master:vnt

• local push: git push vnt vnt:master

log.Info("[info] setBootstrapNodes()", "urls", urls, "and tests", tests, "and url length", len(urls))

• libp2p database tips：

  • when libp2p store key-value, it will make key to hash of key and the key + value + timestamp will be value.

  • when libp2p store key-value, the key should start with \.

develop tips.

• when get the url of bootnodes，we need change it to node，the code is at cmd/utils/flags.go#L610

url = "vnode://123b13dfdb555c69290acf510f2e1c00b9d31a917d8c9e7cf8216812da10caffd6e242879bbae43aa09c3bd2ef49c45999bb0c502d38d8c8f9d60287f2220c0c@127.0.0.1:30301"

node, err := discover.ParseNode(url)

VNT starts

bootnode start

$ cd bootnode-dir
$ bootnode -genkey=node.key
$ bootnode -nodekey=node.key

the database is ：bootnode -datadir="./" -nodekey=node.key。

membernode starts

ATTENTION：

• datadir can't be too long。
• vntbootnode is vnt's``bootnodeURL
• port is vntnode's port

$ gvnt --datadir=./datadir1 --vntbootnode=/ip4/127.0.0.1/tcp/30301/ipfs/QmW1zhpCHrfoyXjWRkJMaTgtfy7BiqhZfHajgK3Xnysoxx --port 30306

producers node starts

$ gvnt account new --datadir ./datadir2

$ gvnt --datadir=./datadir2 --vntbootnode=/ip4/127.0.0.1/tcp/30301/ipfs/QmW1zhpCHrfoyXjWRkJMaTgtfy7BiqhZfHajgK3Xnysoxx --produce --producerthreads=1 --coinbase=0xf6f5038a406a7fe78229a80850ca8ed42fe03bfd --port 30307

now，vntdb is support --datadir tag
