Fedora 27, CentOS 1708, Go-ethereum 1.8.1
I am trying to make private block chain and coin using that for study.
Genesis.json:
{
"config": {
"chainId": 42,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"alloc": {},
"coinbase" : "0x0000000000000000000000000000000000000000",
"difficulty" : "0x1000000",
"extraData" : "",
"gasLimit" : "0x2fefd8",
"nonce" : "0x0000000012345678",
"mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00"
}
And I run geth in console with:
geth init genesis.json --datadir datadir
geth console --rpc --rpcport "8080" --rpccorsdomain "*" --datadir "datadir" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --networkid 7296
Then I made new account and started mining. It works. But when I restart geth, block chain state seems not saved.
INFO [03-05|11:39:03] Successfully sealed new block number=21 hash=ef088f…8b62cb
INFO [03-05|11:39:03] maybe a bug in the current version... start geth with option --gcmode "archive"
