Private Dev Ethereum Network

Building any Dapp on ethereum requires lot of testing and experimentation, So mainnet becomes unusable for any kind of experimentation and testing. We can use testnet but it has following drawbacks-

1) Slow transaction

2) Storage of chain data

3) Time required in syncing with the existing chain data,

4) Requirement of test ether for executing transaction or deploying contracts.

Because of above problems it is better to have private dev network for your testing and experimentation purpose.

What is Private Dev Network ?

• It is an Isolated network with one Node.
• It can process transaction fast.
• Extremely low storage need.

You will require to run mining on this node when you want your transaction to be processed or if you require ether.

How to start Private Dev Network ?

Private Dev Network can be simply started by adding --dev option to existing geth command line.

geth --dev <..other geth cli option.. >
