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.

Of course, Bitcoin’s volatility cannot be managed; against the backdrop of a scarce supply, price is almost exclusively a function of demand. Bitcoin is almost perfectly inelastic in its supply, and so waves of adoption manifest themselves in gut-wrenching price gyrations. This contrasts with sovereign currencies where the central bank pulls various levers to ensure relative exchange rate stability.bitcoin сбербанк mini bitcoin bitcoin fee bitcoin compare roll bitcoin monero кран bitcoin транзакция air bitcoin bitcoin обзор bitcoin golden bitcoin banking ethereum miner bitcoin кошелька scrypt bitcoin ethereum charts bitcoin blog bitcoin asics In a pay-per-share (PPS) system, users are not rewarded based on how many blocks the pool actually finds, but rather on how many blocks the pool was expected to find given the amount of work done by its users. The pool pays a fixed amount of litecoins for each valid share its users submit, based on the mathematical laws of probability. The main advantage of this system is that users can enjoy steady payouts and minimal variance, and don't have to wait for blocks to be found and confirmed. The downside is that the pool operator has to take on the risk of bad luck, so running a PPS pool can be financially risky.day bitcoin

A DAO is a digital organization that operates without hierarchical management; it works in a decentralized and democratic fashion. So basically a DAO is an organization in which the decision-making is not in the hands of a centralized authority but preferably in the hands of certain designated authorities or a group or designated people as a part of an authority. It exists on a blockchain network, where it is governed by the protocols embedded in a smart contract, and thereby, DAOs rely on smart contracts for decision-making—or, we can say, decentralized voting systems—within the organization. So before any organizational decision can be made, it has to go through the voting system, which runs on a decentralized application.coins bitcoin bitcoin prune miningpoolhub ethereum криптовалюта bitcoin

For investors outside the technology industry, understanding this volunteer-based way of working is critical to understanding why Bitcoin operates the way it does, and why it is an improvement on conventional methods of human collaboration. To get to these points, we will first explore the origins of the 'war' that Satoshi is engaged in, and how the invention of Bitcoin is meant to change the tide.ethereum эфириум cryptonator ethereum покупка ethereum bitcoin теханализ No more so than the wastefulness of mining gold out of the ground, melting it down and shaping it into bars, and then putting it back underground again. Not to mention the building of big fancy buildings, the waste of energy printing and minting all the various fiat currencies, the transportation thereof in armored cars by no less than two security guards for each who could probably be doing something more productive, etc.The U.S. is plagued by a fragmented regulatory system, with legislators at both the state and the federal level responsible for layered jurisdictions and a complex separation of powers.bitcoin media ethereum аналитика monero blockchain
