How is Ethereum similar to Bitcoin?
I think it’s easiest to understand Ethereum by exploring the similarities and differences between Ethereum and a simpler system, Bitcoin. So what are the similarities?
Ethereum has a blockchain
Like Bitcoin, Ethereum has a blockchain, which contains blocks of data (transactions and smart contracts). The blocks are created or mined by some participants and distributed to other participants who validate them.
You can explore this blockchain here: https://etherscan.io
Blocks form a chain by referring to the hash or fingerprint of the previous block. See a gentle introduction to blockchain technology for a primer.
Ethereum is public and permissionless
Like Bitcoin, the main Ethereum network is a public, permissionless network – ie anyone can download or write some software to connect to the network and start creating transactions and smart contracts, validating them, and mining blocks without needing to log in or sign up with any other organisation.
In general, when people talk about Ethereum they mean the main public permissionless instance (version) of the network. However, like Bitcoin, you can take Ethereum software, modify it slightly and create private networks that aren’t connected to the main public network. The private tokens and smart contracts won’t be compatible with the public tokens though, for now. For more on the difference between public permissionless and private permissioned networks, see confused by blockchains? Revolution vs Evolution
Ethereum has Proof-of-Work (PoW) mining
Like Bitcoin, mining participants create valid blocks by spending electricity to find solutions to a mathematical puzzle. Ethereum’s PoW maths challenge called Ethash works slightly differently to Bitcoin’s, and this allows common hardware to be used for mining. This reduces the efficiency edge of task-specific hardware known as ASICs, which are common in Bitcoin mining.
For more on mining see a gentle introduction to bitcoin mining.
On Ethereum’s roadmap there is a plan to move from electricity-expensive Proof-of-Work mining to a more energy-efficient Proof-of-Stake protocol called Casper, in a future release of the Ethereum software called Serenity.
Ethereum has an inbuilt cryptocurrency
Ethereum’s token is called Ether, shortened to ETH. This is a cryptocurrency that can be traded for other cryptocurrencies or other sovereign currencies, just like BTC. Its current value is around US$13 per ETH token (Oct 2016). Token ownership is tracked on the Ethereum blockchain, just like BTC ownership is tracked on Bitcoin’s blockchain, though at a technical level they track them in slightly different ways.

In particular, non-upgraded nodes may relay and accept transactions that are considered invalid by upgraded nodes and so will never become part of the universally-recognized best block chain. Non-upgraded nodes may also refuse to relay blocks or transactions which have already been added to the best block chain, or soon will be, and so provide incomplete information.video bitcoin xapo bitcoin king bitcoin erc20 ethereum king bitcoin dog bitcoin сделки bitcoin 2016 bitcoin bitcoin gadget get bitcoin

The Proof-of-Stake mechanism will use a protocol called Casper (yes, as in the friendly ghost. Who says cryptonerds don’t have a sense of humour?). The rate of ETH issuance under Casper may very well be lower than it is now under Ghost.bitcoin сложность Payment (in ETH) = Gas amount (in Gas) x Gas price (in ETH/Gas)bitcoin onecoin

bitcoin price Majority consensus in bitcoin is represented by the longest chain, which required the greatest amount of effort to produce. If a majority of computing power is controlled by honest nodes, the honest chain will grow fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of that block and all blocks after it and then surpass the work of the honest nodes. The probability of a slower attacker catching up diminishes exponentially as subsequent blocks are added.tera bitcoin Here’s the problem. Bitcoin has over $250 billion in market capitalization. Two publicly-traded companies on major exchanges, MicroStrategy (MSTR) and Square (SQ) already own it, as do a variety of public companies on other exchanges and OTC markets, plus private companies and investment funds. Big investors like Cathie Woods, Paul Tudor Jones, and Stanley Druckenmiller own it, as does at least one U.S. senator-elect. Fidelity and a variety of large companies are involved in institutional-grade custodian services for it. PayPal (PYPL) is getting involved. Federally regulated U.S. banks can now officially custody crypto assets. The IRS treats it like a commodity for tax purposes. That’s a lot of mainstream momentum.компиляция bitcoin bitcoin хардфорк бесплатно ethereum bitcoin brokers bitcoin mempool mempool bitcoin скачать bitcoin

Ethereum, now the second largest cryptocurrency, was developed to be broader than Bitcoin in terms of using blockchain technology to transfer various types of value. It is like a decentralized app platform with a built in currency in units of ether. Typical app platforms have a central authority like Google or Apple, and developers can request to put apps on those networks to sell to consumers. Ethereum can do that without the middle man.ethereum android

A generic technique for reducing variance is to use multiple independent sub-challenges, as the average of multiple samples will have a lower variance.I think it’s instructive to look at Satoshi’s ANN thread on the Cryptography newsgroup/mailing list; particularly the various early criticisms:XRPTransactions don't start out as irreversible. Instead, they get a confirmation score that indicates how hard it is to reverse them (see table). Each confirmation takes between a few seconds and 90 minutes, with 10 minutes being the average. If the transaction pays too low a fee or is otherwise atypical, getting the first confirmation can take much longer.bitcoin mac ethereum перспективы bitcoin yandex эфириум ethereum
