EthereumPrice.org was developed by Ether0x in March 2016 to allow users to easily track the price of Ethereum both historically and in real-time. The platform has since evolved to include several fiat currencies (EUR, GBP, JPY and others) as well as price data for a number of Ethereum ERC20 tokens and other blockchain currencies. More recently, prediction data from Augur was also added to provide insight into the future price expectations of the Ether market. Price data is currently sourced from multiple exchanges with the weighted average price of these assets being calculated by CryptoCompare.com. For more details on the weighted average calculation, see our FAQ.

En 1983, el criptógrafo estadounidense David Chaum concibió un sistema criptográfico monetario electrónico llamado eCash. Más tarde, en 1995, implementó DigiCash, que utilizaba la criptografía para volver anónimas las transacciones de dinero, aunque con una emisión y liquidación (pago) centralizado.8​ Este sistema requería un software para retirar dinero de un banco y designar claves cifradas específicas antes de que puedan enviarse a un destinatario. Esto permitió que la moneda digital no fuera rastreable por el banco emisor, el gobierno o cualquier tercero.

Litecoin (LTC or Ł) is a peer-to-peer cryptocurrency and open-source software project released under the MIT/X11 license. Creation and transfer of coins is based on an open source cryptographic protocol and is not managed by any central authority.[citation needed] Litecoin was an early bitcoin spinoff or altcoin, starting in October 2011.[2] In technical details, litecoin is nearly identical to Bitcoin.

Transactions that occur through the use and exchange of these altcoins are independent from formal banking systems, and therefore can make tax evasion simpler for individuals. Since charting taxable income is based upon what a recipient reports to the revenue service, it becomes extremely difficult to account for transactions made using existing cryptocurrencies, a mode of exchange that is complex and difficult to track.[66]

As the industry continues to investigate blockchain platforms, it’s apparent that Ethereum is becoming a de facto leader. For example, a few days ago JPMorgan publicly open-sourced its Quorum platform, architected and developed around the Go Ethereum client by Jeff Wilcke and his team. Several other major banks are using Ethereum, and Microsoft is anchoring its Bletchley platform on it as the foundational blockchain element. Industry, both publicly and confidentially, continues to contribute to Ethereum and work with us and others to help our promising, toddler-age codebase reach maturity. Stay tuned for news on this front.

Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining.[70]

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.

Las tarifas en las criptomonedas dependen principalmente de la oferta de capacidad de cálculo de la red en el momento y de la demanda del usuario de una transacción rápida. El usuario puede escoger una tarifa específica, mientras que los mineros procesan las transacciones en orden decreciente. Se puede simplificar el proceso para el usuario ofreciendo prioridades alternativas y determinando el tiempo que podría tardar cada una.

Otro sistema, prueba de participación, es un método para asegurar la red de alcanzando un consenso distribuido pidiendo a los usuarios la propiedad de una pequeña parte de las unidades. Se diferencia del sistema de prueba de trabajo en que no tienen que ejecutar algoritmos de hashing muy complicados para validar las transacciones. El sistema cambia mucho dependiendo de la moneda y actualmente no hay un estándar. Algunas criptomonedas usan un sistema combinado entre los dos.
The rapid price increase of Ethereum has not only attracted investors but developers too. Ethereum has tens of thousands of developers in its open source community, each contributing to the many layers of the “Ethereum stack”. This includes code contributions to the core Ethereum clients, second layer scaling tech and the “decentralized applications” (dApps) that are built on top of the platform. The appeal of Ethereum to developers is unique in that it was the first platform to allow anyone in the world to write and deploy code that would run without the risk of censorship. The community of developers which have formed around these core principles have led to the creation of technologies that could not have existed without the inception of Ethereum, many of which were never predicted. Some of the major use-cases of Ethereum so far have been:

In March 2018, Binance announced its intentions to open an office in Malta after stricter regulations in Japan and China.[5] In April 2018, Binance signed a Memorandum of Understanding (MoU) with the Government of Bermuda[6]. Months later, a similar memorandum was signed with the Malta Stock Exchange to develop a platform for trading security tokens[7]. In 2019, company announced Binance Jersey, an independent entity from its parent Binance.com exchange, with the aim to expand its European influence. Jersey based exchange offers fiat-to-cryptocurrency pairs, including the Euro and the British pound.[8]
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[37] Popular favorites of cryptocurrency miners such as Nvidia's GTX 1060 and GTX 1070 graphics cards, as well as AMD's RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[38] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[39]

Armed with the knowledge of Ethereum’s price history, future predictions and the associated risks to investing in this cryptocurrency, you may now be considering a purchase. Buying Ethereum has evolved from a niche and slightly cumbersome process to one which has been polished into simplicity. Ethereum can now be bought through debit/credit card, epayment platforms, bank transfer, cash or even Bitcoin and other cryptocurrencies. Speculators can bet on the asset (both long and short) through “contracts for difference” (CFDs) or they can purchase and secure the asset themselves to “become their own bank”.
In 2016 a decentralized autonomous organization called The DAO, a set of smart contracts developed on the platform, raised a record US$150 million in a crowdsale to fund the project.[25] The DAO was exploited in June when US$50 million in ether were taken by an unknown hacker.[26][27] The event sparked a debate in the crypto-community about whether Ethereum should perform a contentious "hard fork" to reappropriate the affected funds.[28] As a result of the dispute, the network split in two. Ethereum (the subject of this article) continued on the forked blockchain, while Ethereum Classic continued on the original blockchain.[29] The hard fork created a rivalry between the two networks.

El concepto o idea de criptomoneda fue descrita por primera vez por Wei Dai, en 1998, donde propuso la idea de crear un nuevo tipo de dinero descentralizado que usara la criptografía como medio de control,11​ mientras que la primera criptomoneda que se creó fue Bitcoin, creada en 2009 por el desarrollador de pseudónimo Satoshi Nakamoto, el cual usa el conjunto de funciones criptográficas SHA-2 (exactamente el SHA-256) como su esquema PoW (prueba de trabajo).12​13​ Posteriormente, han aparecido otras criptomonedas, como Namecoin (un intento de descentralizar el sistema de nombres de dominio DNS, lo que haría muy difícil la censura de internet), Litecoin (el cual utiliza scrypt como esquema PoW, así como también, para tener una confirmación de transacción más rápida), Peercoin (el cual utiliza un esquema híbrido PoW/PoS [prueba de trabajo/prueba de participación], además tiene una tasa de inflación del alrededor de 1 %) y Freicoin (el cuál implementó el concepto de Silvio Gesell agregando depreciación en el tiempo).14​ Muchas otras criptomonedas han sido creadas, aunque no todas han sido exitosas, en especial aquellas que no han aportado ninguna innovación.

The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[23][26] Each block typically contains a hash pointer as a link to a previous block,[26] a timestamp and transaction data.[27] By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".[28] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.

Las criptodivisas descentralizadas son producidas colectivamente por todo el sistema, a un radio públicamente conocido que es especificado cuando ese sistema se crea. En los bancos centrales y en los sistemas económicos tradicionales, los gobiernos controlan la cantidad de monedas en el mercado (por ejemplo, imprimiendo moneda o exigiendo adiciones a los libros de contabilidad). En el caso de las criptomonedas descentralizadas, las empresas o los gobiernos no pueden producir nuevas unidades. Las criptomonedas tampoco tienen un activo detrás que respalde su valor, al contrario de las monedas tradicionales. El sistema actual está basado por el individuo o grupo conocido como Satoshi Nakamoto.19​

Ethereum is also being used as a platform to launch other cryptocurrencies. Because of the ERC20 token standard defined by the Ethereum Foundation, other developers can issue their own versions of this token and raise funds with an initial coin offering (ICO). In this fundraising strategy, the issuers of the token set an amount they want to raise, offer it in a crowdsale, and receive Ether in exchange. Billions of dollars have been raised by ICOs on the Ethereum platform in the last two years, and one of the most valuable cryptocurrencies in the world, EOS, is an ERC20 token.

Ethereum's blockchain uses Merkle trees, for security reasons, to improve scalability, and to optimize transaction hashing.[60] As with any Merkle tree implementation, it allows for storage savings, set membership proofs (called "Merkle proofs"), and light client synchronization. The Ethereum network has at times faced congestion problems, for example, congestion occurred during late 2017 in relation to Cryptokitties.[61]

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 May 2018, Bitcoin Gold (and two other cryptocurrencies) were hit by a successful 51% hashing attack by an unknown actor, in which exchanges lost estimated $18m.[citation needed] In June 2018, Korean exchange Coinrail was hacked, losing US$37 million worth of altcoin. Fear surrounding the hack was blamed for a $42 billion cryptocurrency market selloff.[72] On 9 July 2018 the exchange Bancor had $23.5 million in cryptocurrency stolen.[73]

Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction. The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest. Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time.

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.

Ethereum-based customized software and networks, independent from the public Ethereum chain, are being tested by enterprise software companies.[47] Interested parties include Microsoft, IBM, JPMorgan Chase,[33][48] Deloitte,[49] R3,[50] Innovate UK (cross-border payments prototype).[51] Barclays, UBS and Credit Suisse are experimenting with Ethereum.
Both blockchains have the same features and are identical in every way up to a certain block where the hard-fork was implemented. This means that everything that happened on Ethereum up until the hard-fork is still valid on the Ethereum Classic Blockchain. From the block where the hard fork or change in code was executed onwards, the two blockchains act individually.
