Running Ethereum client and test nets


Ethereum local block chain

Advantage

  • No syncing and almost no data on disk;you mine the primary block yourself.
  • No got to obtain test ether;you “award” yourself mining rewards that you simply can use for testing.
  • No other users,just you.
  • No other contracts,just those you deploy after you launch it.
  • Having no other users means it doesn’t behave an equivalent as a public block chain.
  • No miners aside from you means mining is more predictable;therefore,you can’t test some scenarios that occur on a public block chain.
  • Having no other contracts means you’ve got to deploy everything you would like to check ,including dependencies and contract libraries.
  • You can’t recreate a number of the general public contracts and their dependencies to check some scenarios (e.g; the DAO contracts).

Maximum requirements

  • CPU with 2+ cores
  • At least 80GB free space for storing
  • 4 GB RAM minimum with an SSD,8GB+if you add HDD
  • 8 MBit/Sec download internet service

Recommended requirements

  • Fast CPU with 4+Cores
  • 16 GB+RAM
  • Fast SSD with a minimum of 500GB free space
  • 25+MBit/Sec download internet service
  • The disk size requirements listed here assume you’ll be running a node with default settings,where the blockchain is “pruned” of old state. If you instead run a full”archival” node,where all state is kept disk,it will likely require quite 1TB of disc space .

Test nets

  • Ropsten: A proof-of-work blockchain that the majority closely resembles Ethereum;you can easily mine fox-Ether.
  • Kovan: A proof-of-authority blockchain,started by the Parity team.Ether cannot be mined;it has got to be requested.
  • Rinkeby: A proof-of-authority blockchain,started by the Geth team.Ether cannot be mined;it has got to be requested .
