Blockchain definition
A blockchain is a “cryptographically secure transactional singleton machine with shared-state.” That’s a mouthful, isn’t it? Let’s break it down.
“Cryptographically secure” means that the creation of digital currency is secured by complex mathematical algorithms that are obscenely hard to break. Think of a firewall of sorts. They make it nearly impossible to cheat the system (e.g. create fake transactions, erase transactions, etc.)
“Transactional singleton machine” means that there’s a single canonical instance of the machine responsible for all the transactions being created in the system. In other words, there’s a single global truth that everyone believes in.
“With shared-state” means that the state stored on this machine is shared and open to everyone.
Ethereum implements this blockchain paradigm.
The Ethereum blockchain paradigm explained
The Ethereum blockchain is essentially a transaction-based state machine. In computer science, a state machine refers to something that will read a series of inputs and, based on those inputs, will transition to a new state.

With Ethereum’s state machine, we begin with a “genesis state.” This is analogous to a blank slate, before any transactions have happened on the network. When transactions are executed, this genesis state transitions into some final state. At any point in time, this final state represents the current state of Ethereum.

The state of Ethereum has millions of transactions. These transactions are grouped into “blocks.” A block contains a series of transactions, and each block is chained together with its previous block.

To cause a transition from one state to the next, a transaction must be valid. For a transaction to be considered valid, it must go through a validation process known as mining. Mining is when a group of nodes (i.e. computers) expend their compute resources to create a block of valid transactions.
Any node on the network that declares itself as a miner can attempt to create and validate a block. Lots of miners from around the world try to create and validate blocks at the same time. Each miner provides a mathematical “proof” when submitting a block to the blockchain, and this proof acts as a guarantee: if the proof exists, the block must be valid.
For a block to be added to the main blockchain, the miner must prove it faster than any other competitor miner. The process of validating each block by having a miner provide a mathematical proof is known as a “proof of work.”
A miner who validates a new block is rewarded with a certain amount of value for doing this work. What is that value? The Ethereum blockchain uses an intrinsic digital token called “Ether.” Every time a miner proves a block, new Ether tokens are generated and awarded.
You might wonder: what guarantees that everyone sticks to one chain of blocks? How can we be sure that there doesn’t exist a subset of miners who will decide to create their own chain of blocks?
Earlier, we defined a blockchain as a transactional singleton machine with shared-state. Using this definition, we can understand the correct current state is a single global truth, which everyone must accept. Having multiple states (or chains) would ruin the whole system, because it would be impossible to agree on which state was the correct one. If the chains were to diverge, you might own 10 coins on one chain, 20 on another, and 40 on another. In this scenario, there would be no way to determine which chain was the most “valid.”
Whenever multiple paths are generated, a “fork” occurs. We typically want to avoid forks, because they disrupt the system and force people to choose which chain they “believe” in.

To determine which path is most valid and prevent multiple chains, Ethereum uses a mechanism called the “GHOST protocol.”
“GHOST” = “Greedy Heaviest Observed Subtree”
In simple terms, the GHOST protocol says we must pick the path that has had the most computation done upon it. One way to determine that path is to use the block number of the most recent block (the “leaf block”), which represents the total number of blocks in the current path (not counting the genesis block). The higher the block number, the longer the path and the greater the mining effort that must have gone into arriving at the leaf. Using this reasoning allows us to agree on the canonical version of the current state.

Now that you’ve gotten the 10,000-foot overview of what a blockchain is, let’s dive deeper into the main components that the Ethereum system is comprised of:
accounts
state
gas and fees
transactions
blocks
transaction execution
mining
proof of work
One note before getting started: whenever I say “hash” of X, I am referring to the KECCAK-256 hash, which Ethereum uses.

This is how the Fed manages the relative stability of the dollar. Debt creates future demand for dollars. In the Fed’s system, each dollar is leveraged approximately 40:1. If you borrow dollars today, you need to acquire dollars in the future to repay that debt, and currently, each dollar in the banking system is owed 40 times over. The relationship between the size of the credit system relative to the amount of dollars gives the dollar relative scarcity and stability. In aggregate, everyone needs dollars to repay dollar denominated credit.Because your cryptocurrency holdings aren’t tied to a financial institution or government, they are available to you no matter where you are in the world or what happens to any of the global finance system’s major intermediaries.bitcoin акции zcash bitcoin iso bitcoin lurkmore bitcoin monero address difficulty bitcoin bitcoin explorer 2048 bitcoin bitcoin security bitcoin currency bitcoin lurkmore bitcoin биржи bitcoin перевести bitcoin chain bitcoin spinner bitcoin direct mt5 bitcoin

Suppose you want to execute trades of assets via the block-chain, and not merely record them there. This is possible if the asset is issued digitally on the blockchain itself, and if the blockchain supports smart contracts. In this instance, smart contracts solve the 'fair exchange' problem of ensuring that payment is made if and only if the asset is transferred. More generally, smart contracts can encode complex business logic, provided that all necessary input data (assets, their prices, and so on) are represented on the blockchain.bitcoin кредиты cryptocurrency analytics cpuminer monero кошелек ethereum iso bitcoin is bitcoin bitcoin вконтакте bitcoin com credit bitcoin bitcoin список вики bitcoin bitcoin шрифт bitcoin в bitcoin cgminer bitcoin system

ethereum bitcoin brokers In any case, core developers incur very few monetary costs. Because they are simply donating time, they need only worry about the opportunity cost of the contributions. In short, developers who simply contribute code may be less committed than miners at the outset, but as time goes on, may become increasingly enfranchised in the group dynamic and the technology itself. It’s not necessary for core developers to be friendly with miners, but they do need to remain cognizant of miners’ economics. If the network is not profitable to mine, or the software quality is poor, the network will not attract investment from miners. Without miners’ computational power, a network is weak and easy to attack.вывод ethereum bitcoin форум bitcoin boxbit bitcoin base tether clockworkmod

Public intellectuals like Yuval Noah Harari and Elon Musk have warned that artificial intelligence and big data could strengthen tyrants and authoritarians around the world. Regimes in Venezuela, Iran, and Saudi Arabia are even trying to mutate and centralize Bitcoin’s concept of peer-to-peer digital money to create state-controlled cryptocurrencies like the Petro, which could allow them to more effectively censor transactions, surveil user accounts, and evade sanctions.dag ethereum ферма ethereum all cryptocurrency bitcoin экспресс bitcoin обозначение добыча bitcoin bitcoin update cryptonator ethereum check bitcoin майнинг tether

Miners act as ledger keepers and auditors for all bitcoin transactions.

The first one must be disconnected from any network. It is the only one that holds the entire wallet and is able to sign transactions. The second computer is connected to the network and only has a watching wallet that can only create unsigned transactions. This way, you can securely issue new transactions with the following steps.bitcoin символ Setting up a Litecoin mining operation requires interested parties to make significant investments in hardware.

fpga ethereum Comparatively, a soft fork is backwards-compatible. The upgraded blockchain is responsible for validating transactions. But, nodes which don’t get updated will still see the new blocks as valid. This only works one way; the upgraded blockchain will not recognise the nodes which haven’t been updated. In order for a soft fork to work the majority of miners need to upgrade. The more miners who accept the new rules, the more secure the network will be post-fork. Soft forks have been used on both bitcoin and ethereum blockchains, among others. They are generally used to implement software upgrades (such as BIP 66 in the case of bitcoin).Bitcoin is a type of digital currency which operates outside the mandate of a central authority. There are several variants of the cryptocurrency which have resulted from forks. These include bitcoin cash, bitcoin gold and bitcoin diamond.
