We open for suggestions and improvements. == Token definition == 1. Initializes contract with initial supply tokens to the creator of the contract 2. Internal transfer, only can be called by this contract 3. Transfer/Send tokens to public 4. Receive token from public 5. Destroy tokens (burn) (pre defined amount) 6. Freeze all operations ( implement an emergency stop mechanism) 7. Revert - send back to customer on wrong transaction. On security bridge. Do we can allow revert to ONLY our own wallets ? E.g only if our wallet promised. 8. Check the amount of tokens than an owner allowed to a spender. 9. Limit allowed amount of tokens per/wallet. (what is the limit?) 10. Add upgrade ability. [login to view URL] 11. CrowdSale - Allow to run ICO. 12. External library include implementation. For security. [login to view URL] 13. Multi signature.??? 14. POS - reward holder based on time and token amount. 1) Can we add TokenTimelock for Pos ? 15. TokenTimelock - that will allow a beneficiary to extract the tokens after a time has passed. 16. Airdrop functionality. 1) Can we add this functionality but start using only when needed ?
