Transaction and messages
We noted earlier that Ethereum is a transaction-based state machine. In other words, transactions occurring between different accounts are what move the global state of Ethereum from one state to the next.
In the most basic sense, a transaction is a cryptographically signed piece of instruction that is generated by an externally owned account, serialized, and then submitted to the blockchain.
There are two types of transactions: message calls and contract creations (i.e. transactions that create new Ethereum contracts).
All transactions contain the following components, regardless of their type:
nonce: a count of the number of transactions sent by the sender.
gasPrice: the number of Wei that the sender is willing to pay per unit of gas required to execute the transaction.
gasLimit: the maximum amount of gas that the sender is willing to pay for executing this transaction. This amount is set and paid upfront, before any computation is done.
to: the address of the recipient. In a contract-creating transaction, the contract account address does not yet exist, and so an empty value is used.
value: the amount of Wei to be transferred from the sender to the recipient. In a contract-creating transaction, this value serves as the starting balance within the newly created contract account.
v, r, s: used to generate the signature that identifies the sender of the transaction.
init (only exists for contract-creating transactions): An EVM code fragment that is used to initialize the new contract account. init is run only once, and then is discarded. When init is first run, it returns the body of the account code, which is the piece of code that is permanently associated with the contract account.
data (optional field that only exists for message calls): the input data (i.e. parameters) of the message call. For example, if a smart contract serves as a domain registration service, a call to that contract might expect input fields such as the domain and IP address.

We learned in the “Accounts” section that transactions — both message calls and contract-creating transactions — are always initiated by externally owned accounts and submitted to the blockchain. Another way to think about it is that transactions are what bridge the external world to the internal state of Ethereum.

But this doesn’t mean that contracts can’t talk to other contracts. Contracts that exist within the global scope of Ethereum’s state can talk to other contracts within that same scope. The way they do this is via “messages” or “internal transactions” to other contracts. We can think of messages or internal transactions as being similar to transactions, with the major difference that they are NOT generated by externally owned accounts. Instead, they are generated by contracts. They are virtual objects that, unlike transactions, are not serialized and only exist in the Ethereum execution environment.
When one contract sends an internal transaction to another contract, the associated code that exists on the recipient contract account is executed.

One important thing to note is that internal transactions or messages don’t contain a gasLimit. This is because the gas limit is determined by the external creator of the original transaction (i.e. some externally owned account). The gas limit that the externally owned account sets must be high enough to carry out the transaction, including any sub-executions that occur as a result of that transaction, such as contract-to-contract messages. If, in the chain of transactions and messages, a particular message execution runs out of gas, then that message’s execution will revert, along with any subsequent messages triggered by the execution. However, the parent execution does not need to revert.

For the past two weeks, validators have been earning roughly 0.008 ETH/day, which is valued at around $8.86/day at time of writing. Initially, the daily average had reached as high as 0.01 ETH/day but this was largely due to the low number of active validators present on the network. The reward system of Eth 2.0 is dynamically structured so that an increasing number of Eth 2.0 validators will trigger lower validator returns and vice versa. bitcoin деньги mine monero ethereum investing monero cryptonight bitcoin стратегия

Gox as a positive for the long term prospects of bitcoin, further complicating the already complex story behind the currency’s volatility.

locate bitcoin ethereum кошелька bitcoin currency видеокарты bitcoin bitcoin gambling Since 2007, the Fed balance sheet has increased seven-fold, but the labor force has only increased 6%. There are roughly the same number of people contributing output (human time) but far more dollars to compensate for that time. Do not be confused by impossible-to-quantify theory concerning the idea of a job saved versus a job lost; this is the U.S. labor force, defined by the Bureau of Labor Statistics as all persons 16 years of age and older, both employed and unemployed. The inevitable result is that the value of each dollar declines, but it does not create more workers, and all prices do not adjust ratably to the increase in the money supply, including the price of labor. bitcoin lottery bitcoin rt ethereum доллар cranes bitcoin bitcoin start сложность bitcoin abi ethereum криптовалюта monero bitcoin теханализ monero client crococoin bitcoin bitcoin 50 bitcoin hosting cryptocurrency ico bitcoin падает monero хардфорк bitcoin пузырь bitcoin python iso bitcoin bitcoin покупка monero майнить plasma ethereum ann bitcoin что bitcoin abi ethereum bitcoin миксеры bitcoin hack bitcoin segwit2x 5 bitcoin ann bitcoin
