It's rather interesting to see that >80% of the posts here discuss IPO and mining and very few posts discuss the interesting aspects like the scripting language or transaction logic, privacy, etc...
Agree. Let's discuss fee, for example:
Ethereum will have seven primary fees, of which one applies to transaction senders and six apply to contracts. The fees are:
TXFEE (100x) - fee for sending a transaction
NEWCONTRACTFEE (100x) - fee for creating a new contract, not including the memory fee for each item in script code
STEPFEE (1x) - fee for every computational step after than first sixteen in contract execution
STORAGEFEE (5x) - per-byte fee for adding to contract storage. The storage fee is the only fee that is not paid to a miner, and is refunded when storage used by a contract is reduced or removed.
DATAFEE (20x) - fee for accessing or setting a contract's memory from inside that contract
EXTROFEE (40x) - fee for accessing memory from another contract inside a contract
CRYPTOFEE (20x) - fee for using any of the cryptographic operations
Why these magic numbers? I prefer numbers that r power of 2. Why not numbers set by the market? U can't win in a battle against market, if ur guess on numbers is incorrect the market will just adopt Cryptoneum or any other copycat.
