Ethereum enables developers to build and deploy decentralized applications. A decentralized application or Dapp serve some particular purpose to its users. Bitcoin, for example, is a Dapp that provides its users with a peer to peer electronic cash system that enables online Bitcoin payments. Because decentralized applications are made up of code that runs on a blockchain network, they are not controlled by any individual or central entity.
While another less aggressive soft fork solution was put forth, the Ethereum community and its founders were placed in a perilous position. If they didn’t retrieve the stolen investor money, confidence in Ethereum could be lost. On the other hand, recovering investor money required actions that went against the core ideas of decentralization and set a dangerous precedent.

لعلّ العملات المشفّرة من أهم التقنيات الّتي أوجدها البشر، وهي تقنية سترسم معالم المستقبل، ولربما ستستبدل كل التقنيات الحالية الّتي نستخدمها لتداول الأموال والشراء والبيع. إلّا أنّ ذلك لم يمنع بعضهم من إنشاء بعض العملات الّتي تحمل بعض الطرافة والجنون، وهذه قائمة من خمس عملات بدأت من خلال المزاح إلا أنّها تحولّت فيما بعد إلى عملات ذات شأن واحتلت مراكز متقدمة في قوائم العملات بمختلف التصنيفات، إلا أنّ تصنيف الطرافة بقي الأهم.
ما هو الفرق بين عملة معماة وBlockchain
Essentially, if you are interested in trading in digital currencies but don't want to get bogged down in the underlying technology, products like Coinbase are a way to begin a foray into a new form of currency speculation and investing. You do, however, lose some of the advantages of trading in a cryptocurrency and through the blockchain. On Coinbase, you have no pseudo anonymity—your name is attached to your Coinbase account and so is your bank account, so transaction history is relatively easy to track down. And if you're not working on the blockchain, there's not much you can do to ensure that the verification of your transaction history or your account is taking place on the blockchain. You are, instead, placing trust in the intermediary, in this case, Coinbase.

For those of you who have not been paying attention to one of the biggest trends in investing and tech, cryptocurrencies are digital currencies using encryption techniques that regulate the generation of currency and verify the transfer of funds, operating independently of a central bank. Units of currency are created through a process referred to as mining.
Ethereum has recently created a new standard called the ERC721 token for tracking unique digital assets. One of the biggest use cases currently for such tokens is digital collectibles, as the infrastructure allows for people to prove ownership of scarce digital goods. Many games are currently being built using this technology, such as the overnight hit CryptoKitties, a game where you can collect and breed digital cats.
In 2014, the company grew to one million users, acquired the blockchain explorer service Blockr and the web bookmarking company Kippt, secured insurance covering the value of bitcoin stored on their servers, and launched the vault system for secure bitcoin storage. Throughout 2014, the company also formed partnerships with Overstock, Dell, Expedia, Dish Network, and Time Inc. allowing those firms to accept bitcoin payments. The company also added bitcoin payment processing capabilities to the traditional payment companies Stripe, Braintree, and PayPal.

Ethereum can also be used to build Decentralized Autonomous Organizations (DAO). A DAO is fully autonomous, decentralized organization with no single leader. DAO’s are run by programming code, on a collection of smart contracts written on the Ethereum blockchain. The code is designed to replace the rules and structure of a traditional organization, eliminating the need for people and centralized control. A DAO is owned by everyone who purchases tokens, but instead of each token equating to equity shares & ownership, tokens act as contributions that give people voting rights.
So the app is pretty great when it comes to buying crypto, they can give you the funds immediately at the current price of the crypto, so high purchasing fees and selling it on a quick time line are virtually non existent when you are making small orders, most likely biggers as well. Not so fast... if you purchased it through your bank, because the allowance is higher on it than 25$ for a new card, your funds are basically frozen for 2 weeks. You can not cash out, nor you can send crypto to another wallet, so if you are looking for something to transaction with this isn’t the greatest app to do it with. I’m stuck with funds frozen for already 10 days, and now I have to wait another 5 for the banks to clear it, when on the card is faster, but you are stuck with the same high cost for selling it which comes out to bite you in the but for the fees. Yes, I can sell it and wait at usd wallet so the price doesn’t fluctuate, but again, if you want to get the funds out they are the power delay and have no intention to speed the process and again, you are in lala land waiting for it! Before, it’s not used be this bad but seems like delays and restrictions will expand. For the high cost of buying, and buying always at a higher price than it actually is, it makes even more worthless, even waisting time and resources just on trying to obtain some btc. There are better apps and cheaper apps that don’t cause you such issues. Good luck crypto fans

In October 2015, a development governance was proposed as Ethereum Improvement Proposal, aka EIP, standardized on EIP-1. The core development group and community were to gain consensus by a process regulated EIP. A few notable decisions were made in the process of EIP, such as EIP-160 (EXP cost increase caused by Spurious Dragon Hardfork) and EIP-20 (ERC-20 Token Standard). In January 2018, the EIP process was finalized and published as EIP-1 status turned "active". Alongside ERC-20, notable EIPs to have become finalised token standards include ERC-721 (enabling the creation of non-fungible tokens, as used in Cryptokitties) and as of June 2019, ERC-1155  (enabling the creation of both fungible and non-fungible tokens within a single smart contract with reduced gas costs).

In January 2015, the company received a US$75 million investment, led by Draper Fisher Jurvetson, the New York Stock Exchange, USAA, and several banks. Later in January, the company launched a U.S.-based bitcoin exchange for professional traders called Coinbase Exchange. Coinbase began to offer services in Canada in 2015, but in July 2016, Coinbase announced it would halt services in August after the closure of their Canadian online payments service provider Vogogo.

1. The blockchain is a ledger that keeps track of how much ‘stuff’ (ie BTC, ETH,…create your own currency if you wish) you have. Its the history of transactions. ‘Ethereum’ provides a platform for building contracts…if a contract’s conditions are met, then a transaction (whose rules and automation are agreed ahead of time) automatically occurs and the result of that transaction becomes a part of the ledger. Anyone will be able to see that an address (sellers’ public key) has given ‘stuff’ to another address (purchasers’ public key).

Until relatively recently, building blockchain applications has required a complex background in coding, cryptography, mathematics as well as significant resources. But times have changed. Previously unimagined applications, from electronic voting & digitally recorded property assets to regulatory compliance & trading are now actively being developed and deployed faster than ever before. By providing developers with the tools to build decentralized applications, Ethereum is making all of this possible.

Like Bitcoin, Ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capability. Bitcoin offers one particular application of blockchain technology, a peer to peer electronic cash system that enables online Bitcoin payments. While the Bitcoin blockchain is used to track ownership of digital currency (bitcoins), the Ethereum blockchain focuses on running the programming code of any decentralized application.

There is ongoing research on how to use formal verification to express and prove non-trivial properties. A Microsoft Research report noted that writing solid smart contracts can be extremely difficult in practice, using The DAO hack to illustrate this problem. The report discussed tools that Microsoft had developed for verifying contracts, and noted that a large-scale analysis of published contracts is likely to uncover widespread vulnerabilities. The report also stated that it is possible to verify the equivalence of a Solidity program and the EVM code.

IE… I have 50 ETH , and want to buy a ‘widget’ for 25 ETH given a particular set of circumstances (it works, or the temperature is >10c tomorrow). I agree with a seller on the conditions of a contract, and we ‘create’ a contract on an Ethereum platform, with appropriate sign-offs and verification. This could be 2 steps, or it could be 1000 steps. Once established in the ‘smart contract’, if it is indeed >10c tomorrow, the contract automatically shifts 25 ETH to your account and ships me my widget. The results are recorded in the blockchain.

In the end, the majority of the Ethereum community voted to perform a hard fork, and retrieve The DAO investors money. But not everyone agreed with this course of action. This resulted in a split where two parallel blockchains now exist. For those members who strongly disagree with any changes to the blockchain even when hacking occurs there is Ethereum classic. For the majority who agreed to rewrite a small part of the blockchain and return the stolen money to their owners, there is Ethereum.

In February 2019, Coinbase announced that it had acquired "blockchain intelligence platform" Neutrino, an Italy-based startup, for an undisclosed price. The acquisition raised concern among some Coinbase users based on Neutrino founders' connection to the Hacking Team, which has been accused of providing internet surveillance technology to governments with poor human rights records. On March 4, 2019, Coinbase CEO Brian Armstrong said his company "did not properly evaluate" the deal from a due diligence perspective and thus any Neutrino staff who previously worked at Hacking Team "will transition out of Coinbase."
