Ethereum Level DB schema review

Author: SigmoiD(alphabet@hotmail.co.kr)
(RLP Decoding reference: https://github.com/ethereum/wiki/wiki/RLP)

Scenario summary

1. There are 2 Accounts.
2. Coinbase mined block 1,2 - so balance of coinbase is 10 ether
3. Create 1 trasaction, Sends 1 ether to other.
4. Coinbase mined block 3 with transaction - so balances are 10 + (5-1) ether, 1 ether each.

Additional info

Accounts { cea8f2236efa20c8fadeb9d66e398a6532cca6c8 - coinbase 8e64566b5eb8f595f7eb2b8d302f2e5613cb8bae }
