Transaction Execution
We’ve come to one of the most complex parts of the Ethereum protocol: the execution of a transaction. Say you send a transaction off into the Ethereum network to be processed. What happens to transition the state of Ethereum to include your transaction?

First, all transactions must meet an initial set of requirements in order to be executed. These include:
The transaction must be a properly formatted RLP. “RLP” stands for “Recursive Length Prefix” and is a data format used to encode nested arrays of binary data. RLP is the format Ethereum uses to serialize objects.
Valid transaction signature.
Valid transaction nonce. Recall that the nonce of an account is the count of transactions sent from that account. To be valid, a transaction nonce must be equal to the sender account’s nonce.
The transaction’s gas limit must be equal to or greater than the intrinsic gas used by the transaction. The intrinsic gas includes:
a predefined cost of 21,000 gas for executing the transaction
a gas fee for data sent with the transaction (4 gas for every byte of data or code that equals zero, and 68 gas for every non-zero byte of data or code)
if the transaction is a contract-creating transaction, an additional 32,000 gas

The sender’s account balance must have enough Ether to cover the “upfront” gas costs that the sender must pay. The calculation for the upfront gas cost is simple: First, the transaction’s gas limit is multiplied by the transaction’s gas price to determine the maximum gas cost. Then, this maximum cost is added to the total value being transferred from the sender to the recipient.

If the transaction meets all of the above requirements for validity, then we move onto the next step.
First, we deduct the upfront cost of execution from the sender’s balance, and increase the nonce of the sender’s account by 1 to account for the current transaction. At this point, we can calculate the gas remaining as the total gas limit for the transaction minus the intrinsic gas used.

Next, the transaction starts executing. Throughout the execution of a transaction, Ethereum keeps track of the “substate.” This substate is a way to record information accrued during the transaction that will be needed immediately after the transaction completes. Specifically, it contains:
Self-destruct set: a set of accounts (if any) that will be discarded after the transaction completes.
Log series: archived and indexable checkpoints of the virtual machine’s code execution.
Refund balance: the amount to be refunded to the sender account after the transaction. Remember how we mentioned that storage in Ethereum costs money, and that a sender is refunded for clearing up storage? Ethereum keeps track of this using a refund counter. The refund counter starts at zero and increments every time the contract deletes something in storage.
Next, the various computations required by the transaction are processed.
Once all the steps required by the transaction have been processed, and assuming there is no invalid state, the state is finalized by determining the amount of unused gas to be refunded to the sender. In addition to the unused gas, the sender is also refunded some allowance from the “refund balance” that we described above.
Once the sender is refunded:
the Ether for the gas is given to the miner
the gas used by the transaction is added to the block gas counter (which keeps track of the total gas used by all transactions in the block, and is useful when validating a block)
all accounts in the self-destruct set (if any) are deleted
Finally, we’re left with the new state and a set of the logs created by the transaction.
Now that we’ve covered the basics of transaction execution, let’s look at some of the differences between contract-creating transactions and message calls.
Contract creation
Recall that in Ethereum, there are two types of accounts: contract accounts and externally owned accounts. When we say a transaction is “contract-creating,” we mean that the purpose of the transaction is to create a new contract account.
In order to create a new contract account, we first declare the address of the new account using a special formula. Then we initialize the new account by:
Setting the nonce to zero
If the sender sent some amount of Ether as value with the transaction, setting the account balance to that value
Deducting the value added to this new account’s balance from the sender’s balance
Setting the storage as empty
Setting the contract’s codeHash as the hash of an empty string
Once we initialize the account, we can actually create the account, using the init code sent with the transaction (see the “Transaction and messages” section for a refresher on the init code). What happens during the execution of this init code is varied. Depending on the constructor of the contract, it might update the account’s storage, create other contract accounts, make other message calls, etc.
As the code to initialize a contract is executed, it uses gas. The transaction is not allowed to use up more gas than the remaining gas. If it does, the execution will hit an out-of-gas (OOG) exception and exit. If the transaction exits due to an out-of-gas exception, then the state is reverted to the point immediately prior to transaction. The sender is not refunded the gas that was spent before running out.
Boo hoo.
However, if the sender sent any Ether value with the transaction, the Ether value will be refunded even if the contract creation fails. Phew!
If the initialization code executes successfully, a final contract-creation cost is paid. This is a storage cost, and is proportional to the size of the created contract’s code (again, no free lunch!) If there’s not enough gas remaining to pay this final cost, then the transaction again declares an out-of-gas exception and aborts.
If all goes well and we make it this far without exceptions, then any remaining unused gas is refunded to the original sender of the transaction, and the altered state is now allowed to persist!
Hooray!
Message calls
The execution of a message call is similar to that of a contract creation, with a few differences.
A message call execution does not include any init code, since no new accounts are being created. However, it can contain input data, if this data was provided by the transaction sender. Once executed, message calls also have an extra component containing the output data, which is used if a subsequent execution needs this data.
As is true with contract creation, if a message call execution exits because it runs out of gas or because the transaction is invalid (e.g. stack overflow, invalid jump destination, or invalid instruction), none of the gas used is refunded to the original caller. Instead, all of the remaining unused gas is consumed, and the state is reset to the point immediately prior to balance transfer.
Until the most recent update of Ethereum, there was no way to stop or revert the execution of a transaction without having the system consume all the gas you provided. For example, say you authored a contract that threw an error when a caller was not authorized to perform some transaction. In previous versions of Ethereum, the remaining gas would still be consumed, and no gas would be refunded to the sender. But the Byzantium update includes a new “revert” code that allows a contract to stop execution and revert state changes, without consuming the remaining gas, and with the ability to return a reason for the failed transaction. If a transaction exits due to a revert, then the unused gas is returned to the sender.

'But those who clamor for 'conscious direction'—and who cannot believe that anything which has evolved without design (and even without our understanding it) should solve problems which we should not be able to solve consciously—should remember this: The problem is precisely how to extend the span of our utilization of resources beyond the span of the control of any one mind; and therefore, how to dispense with the need of conscious control, and how to provide inducements which will make the individuals do the desirable things without anyone having to tell them what to do.' – Hayek, The Use of Knowledge in Society.Bitcoin is Common Senseяндекс bitcoin topfan bitcoin bitcoin com япония bitcoin logo ethereum cryptocurrency news рынок bitcoin logo ethereum bitcoin графики

best bitcoin nicehash ethereum monero новости bitcoin ecdsa Time for a reality check. A prudent person should assume Bitcoin will fail, if for no other reason than that most new things fail. But, there is a very real chance it will succeed, and this chance is increased with every new user, every new business, and every new system developed within the Bitcoin economy. The ramifications of success are extraordinary, and it is thus worth at least a cursory review by any advocate of liberty, not just in the US but around the world.kran bitcoin bitcoin sweeper bitcoin hacker bitcoin wordpress bitcoin carding hardware bitcoin ethereum картинки капитализация ethereum cryptocurrency forum bitcoin location bitcoin novosti bitmakler ethereum ethereum рост payable ethereum сайт bitcoin keyhunter bitcoin monero кошелек bitcoin окупаемость майн bitcoin paidbooks bitcoin продам bitcoin

Thus the inclusion of seizure resistance (this is also sometimes referred to as ‘tamper resistance’ or ‘judgment resistance’). By this I mean the ability of users to retain access to their Bitcoin under duress, during times of upheaval or displacement, all in a peaceful and covert way.ethereum install Without question, investments (in financial assets or otherwise) are not the equivalent of savings and there is nothing normal or natural about risk taking induced by central banks which create a disincentive to save. Anyone with common sense and real world experience understands that. Even still, it doesn’t change the fact that money loses its value every year (because it does) and the knowledge of that fact very rationally dictates behavior. Everyone has been forced to accept a manufactured dilemma. The idea that you must make your money grow is one of the greatest lies ever told. It isn’t true at all. Central banks have created that false dilemma. The greatest trick that central banks ever pulled was convincing the world that individuals must perpetually take risk just to preserve value already created (and saved). It is insane, and the only practical solution is to find a better form of money which eliminates the negative asymmetry inherent to systemic currency debasement. That is what bitcoin represents. A better form of money that provides all individuals with a credible path to opt out and to get off the hamster wheel.Calculate the transaction fee as STARTGAS * GASPRICE, and determine the sending address from the signature. Subtract the fee from the sender's account balance and increment the sender's nonce. If there is not enough balance to spend, return an error.bitcoin ethereum Ethereum has an unusually long list of founders. Anthony Di Iorio wrote: 'Ethereum was founded by Vitalik Buterin, Myself, Charles Hoskinson, Mihai Alisie %trump2% Amir Chetrit (the initial 5) in December 2013. Joseph Lubin, Gavin Wood, %trump2% Jeffrey Wilcke were added in early 2014 as founders.' Formal development of the software began in early 2014 through a Swiss company, Ethereum Switzerland GmbH (EthSuisse). The basic idea of putting executable smart contracts in the blockchain needed to be specified before the software could be implemented. This work was done by Gavin Wood, then the chief technology officer, in the Ethereum Yellow Paper that specified the Ethereum Virtual Machine. Subsequently, a Swiss non-profit foundation, the Ethereum Foundation (Stiftung Ethereum), was created as well. Development was funded by an online public crowdsale from July to August 2014, with the participants buying the Ethereum value token (Ether) with another digital currency, Bitcoin. While there was early praise for the technical innovations of Ethereum, questions were also raised about its security and scalability.balance bitcoin bitcoin trojan bitcoin 20 bitcoin обои bitcoin weekend bitcoin ukraine bitcoin legal bitcoin оплата ethereum краны bitcoin 20 fast bitcoin bitcoin обменники forecast bitcoin продам ethereum bitcoin update bitcoin litecoin monero fork bitcoin код майнить bitcoin bitcoin оплата bitcoin rpg second bitcoin bitcoin доходность bitcoin center maps bitcoin bitcoin miner bitcoin выиграть freeman bitcoin bitcoin программирование продам bitcoin lamborghini bitcoin bitcoin биткоин bitcoin scam polkadot su биржа ethereum bitcoin china bitcoin хешрейт
