after creating an token I want to create a crowd sale. But after copying I got this error:

Unused local variable
contract token { function transfer(address receiver, uint amount){ } }
^--------------^
,

What does that mean?

@Cristyander I cannot answer yes or no. Your question does not look like a proposition.

@jjcool the managers can hold private keys, and send a transaction containing a sequence "I approve somthihng something" . After the transaction is included in a block in the chain, the message will be visible on the blockchain explorers.

ok , can a consensus be attained like PBFT where the nodes vote and majority leads to addition of block ?

@jjcool you said you wish to do all on ethereum platform. In that case, you should just send transactions to the Ethereum network. You do not need to implement PBFT yourself in that case.

@jjcool I cannot imagine how you use PBFT from your question. I don't know what is being asked.

@pirapira can i use PBFT in place of PoW on my test-net(block chain) ?
*in developer environment

@jjcool for that you have to implement PBFT yourself.

well , https://github.com/ethereum/wiki/wiki/Consortium-Chain-Development this talks about consensus using PBFT

Hi all, I have a question please - can I setup a coin where I can increase the number of coins in circulation as desired subject to specific criteria?

Hi Yoichi; thanks - can you please tell me more or refer me to some link explaining this please?

@arff123 I've never seen a document specifically about that. Once you implement tokens with constant circulation, it's straightforward to change the code so that the circulation changes.
