Trying to dive into Ethereum

Getting some ether

Reading about rinkeby. Apparently this could be used for play and testing in real network. Unfortunately I already waste invest 50k rupiah to buy real ether in Meh.

Use metamask. Generate some address. Go to to get some free ether.

Send some ether to my friends address for fun XD

Rinkeby geth

Trying to connect to rinkeby network with geth.

geth –networkid=4 –datadir=”D:\Program\Rinkeby Blockchain” –syncmode=light –ethstats=’’ –bootnodes=enode://a24ac7c5484ef4ed0c5eb2d36620ba4e4aa13b8c84684e1b4aab0cebea2ae45cb4d375b77eab56516d34bfbd3c1a833fc51296ff084b770b94fb9028c4d25ccf@

Start time 16 Nov 2017 11:17 GMT

Always got WARN [11-16|23:18:04] Stats login failed err=unauthorized Maybe need to change the --ethstats value? Need to change to unique node name, but doesn’t work too :(

Pause at 17 Nov 2017 00:16 GMT. Syncing 434048 from 1.5M blocks. It just takes too long and I don’t want to waste electricity and bandwith. I doesn’t really need it to learn anyway. I can use online viper compiler and deploy/interact with smart contract using MyEtherWallet.

Creating ENS

Try to register a fancy address name, adhikasp.test.

ENS public resolver

Can’t make it works.

Deploying Hello World contract

Ty for the tutorial

deployed on rinkenby

Reading and modifying data works. But I can’t withdraw the contract’s earnings using the owner addres. TX always failing. HALP!
