Ethereum addresses are composed of the prefix "0x", a common identifier for hexadecimal, concatenated with the rightmost 20 bytes of the Keccak-256 hash (big endian) of the ECDSA public key (the curve used is the so called secp256k1, the same as Bitcoin). In hexadecimal, 2 digits represents a byte, meaning addresses contain 40 hexadecimal digits. An example of an Ethereum address is 0xb794F5eA0ba39494cE839613fffBA74279579268. Contract addresses are in the same format, however they are determined by sender and creation transaction nonce.[34] User accounts are indistinguishable from contract accounts given only an address for each and no blockchain data. Any valid Keccak-256 hash put into the described format is valid, even if it does not correspond to an account with a private key or a contract. This is unlike Bitcoin, which uses base58check to ensure that addresses are properly typed.
Capitalización. Si ordenas las criptomonedas según su capitalización, podrás ver cuáles son las mayores criptodivisas que existen. Durante años, el bitcoin ha sido el activo digital con más valor, seguido siempre por ethereum. Sin embargo, las tornas han cambiado y el ether ha sido superado por Ripple como la segunda mayor criptomoneda por capitalización del mercado.

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.

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.

Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain.[29] Blockchains solve the double-spending problem without the need of a trusted authority or central server, assuming no 51% attack (that has worked against several cryptocurrencies).

La validez de cada una de las unidades está en la cadena de bloques. Una cadena de bloques es una lista en constante crecimiento de registros, llamados bloques, que son enlazados y asegurados usando criptografía. Cada bloque contiene un puntero hash enlazando a un bloque previo, una fecha y datos de transacciones. Por diseño, las cadenas de bloques son inherentemente resistentes a la modificación de los datos.
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet.[71] The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.

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.

Ethereum provides a decentralized virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes.[4] The virtual machine's instruction set, in contrast to others like Bitcoin Script, is thought to be Turing-complete. "Gas", an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network.[4]

La cadena de bloques es un "libro abierto, público, distribuido que registra todas las transacciones efectuadas entre dos usuarios de una manera permanente y verificable". La cadena de bloques usualmente es administrada por una red de punto-a-punto colectiva con un protocolo común para añadir y validar nuevos bloques. Una vez registrados, los datos de cualquier bloque no pueden ser modificados sin alterar todos los siguientes bloques.

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.

“A DAO consists of one or more contracts and could be funded by a group of like-minded individuals. A DAO operates completely transparently and completely independently of any human intervention, including its original creators. A DAO will stay on the network as long as it covers its survival costs and provides a useful service to its customer base” Stephen Tual, Slock.it Founder, former CCO Ethereum.
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.

In March 2017, various blockchain start-ups, research groups, and Fortune 500 companies announced the creation of the Enterprise Ethereum Alliance (EEA) with 30 founding members.[16] By May, the nonprofit organization had 116 enterprise members—including ConsenSys, CME Group, Cornell University's research group, Toyota Research Institute, Samsung SDS, Microsoft, Intel, J. P. Morgan, Cooley LLP, Merck KGaA, DTCC, Deloitte, Accenture, Banco Santander, BNY Mellon, ING, and National Bank of Canada.[17][18][19] By July 2017, there were over 150 members in the alliance, including recent additions MasterCard, Cisco Systems, Sberbank and Scotiabank.[20][21]

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.
Ethereum’s core innovation, the Ethereum Virtual Machine (EVM) is a Turing complete software that runs on the Ethereum network. It enables anyone to run any program, regardless of the programming language given enough time and memory. The Ethereum Virtual Machine makes the process of creating blockchain applications much easier and efficient than ever before. Instead of having to build an entirely original blockchain for each new application, Ethereum enables the development of potentially thousands of different applications all on one platform.
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:

Zcoin is a privacy focused cryptocurrency that was originally built on the Zerocoin protocol. However, given a number of vulnerabilities in that protocol, they recently moved to a new "Sigma" Protocol that was launched in 2019. Transactions are made private by a privacy enhancement in the protocol called "minting". Before you are able to send transactions, you have to mint new coins. Given that all coin’s transactions originate from a newly minted coin, it is hard to track the origin. Privacy on Zcoin is made possible through the use of Zero Knowledge proofs. You also have Tor integration as well as their recently released "Dandelion" protocol. This will further help to cement user privacy on the network. ZCoin uses a the Merkle Tree Proof of Work algorithm (MTP). This is a memory hard algorithm that is considered to be ASIC resistant and hence less prone to centralisation. Zcoin also has a masternode architecture with their "Znodes" (require 1,000 XZC to stake). In compensation for running this full node, the Znode will receive 30% of the newly minted Zcoins. The team behind the Zcoin protocol is quite extensive experience in blockchain engineering, software development, cryptography and many more. The developers have also been hard at work if you take a look into their GitHub repository. When it comes to markets, XZC is listed on a number of exchanges including MXC, Coinex, Binance, Huobi etc. There appears to be reasonable liquidity on these exchanges which will ease execution. However, XZC is still volatile so trade with caution. *Coin Bureau's views are not investment advice. Do Your Own Research.

It takes a (global) village to raise a blockchain. The live network and the community of open source developers contribute significantly to this effort. They continuously refine and harden the Ethereum platform, helping it get faster at responding to industry demands for the value propositions it offers. These investments of time and resources speak to their faith in Ethereum governance and the value that businesses and developers see in its capabilities. – Joseph Lubin, CEO of Consensys

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.

En febrero de 2018, el gobierno Chino detuvo el comercio con criptomonedas, prohibiendo la minería. Algunos mineros se han mudado a Canadá. Algunas empresas están usando centros de datos para la minería cerca de estaciones de gas canadienses, debido a los bajos precios. En junio de 2018, Hydro Quebec propuso al gobierno regional suministrar 500MW de potencia a compañías de minados. Según una noticia de febrero de 2018 de Fortune21​, Islandia se ha convertido en el "cielo" para los mineros, en parte por los precios de la electricidad, muy baratos. Los precios son estables debido a que están cerca de plantas energéticas de energías renovables, incitando a más compañías de minado a considerar el traslado de sus operaciones a Islandia. La compañía local de energía dice que el minado se está volviendo tan popular que el país usará más electricidad para el minado que para el suministro de energía a los hogares en 2018. En octubre de 2018, Rusia se convertirá en el anfitrión de una de las mayores granjas de minado en el mundo, localizada en Siberia.

The "Metropolis Part 1: Byzantium" soft[citation needed] fork took effect on 16 October 2017, and included changes to reduce the complexity of the EVM and provide more flexibility for smart contract developers. Byzantium also added supports for zk-SNARKs (from Zcash), with the first zk-SNARK transaction occurring on testnet on September 19, 2017.[citation needed]
Last week was relatively quiet in Ethereum land; the World Bank sold $33.8 million in another round of its private Ethereum blockchain bonds (not public chain activity but interesting nonetheless) and Mark Carney (Bank of England Governor) discussed the major advantages of a world reserve currency at an annual gathering of central bankers in Wyoming – drawing many parallels to that proposed by Facebook’s Libra cryptocurrency.

Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last[92] and links it to Tulip mania.[93] American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending.[94] In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'.[95] "Bitcoin just shows you how much demand for money laundering there is in the world," he said.

Ethereum was announced at the North American Bitcoin Conference in Miami, in January, 2014.[9] During the same time as the conference, a group of people rented a house in Miami: Gavin Wood, Charles Hoskinson, and Anthony Di Iorio, a Torontonian who financed the project.[9] Di Iorio invited friend Joseph Lubin, who invited reporter Morgen Peck, to bear witness.[9] Six months later the founders met again in a house in Zug, Switzerland, where Buterin told the founders that the project would proceed as a non-profit. Hoskinson left the project at that time.[9]

Smart contract is just a phrase used to describe a computer code that can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Because smart contracts run on the blockchain, they run exactly as programmed without any possibility of censorship, downtime, fraud or third-party interference.

Just like bitcoin, litecoin is a crytocurrency that is generated by mining. Litecoin was created in October 2011 by former Google engineer Charles Lee. The motivation behind its creation was to improve upon bitcoin. The key difference for end-users being the 2.5 minute time to generate a block, as opposed to bitcoin’s 10 minutes. Charles Lee now works for Coinbase, one of the most popular online bitcoin wallets.
Ethereum addresses are composed of the prefix "0x", a common identifier for hexadecimal, concatenated with the rightmost 20 bytes of the Keccak-256 hash (big endian) of the ECDSA public key (the curve used is the so called secp256k1, the same as Bitcoin). In hexadecimal, 2 digits represents a byte, meaning addresses contain 40 hexadecimal digits. An example of an Ethereum address is 0xb794F5eA0ba39494cE839613fffBA74279579268. Contract addresses are in the same format, however they are determined by sender and creation transaction nonce.[34] User accounts are indistinguishable from contract accounts given only an address for each and no blockchain data. Any valid Keccak-256 hash put into the described format is valid, even if it does not correspond to an account with a private key or a contract. This is unlike Bitcoin, which uses base58check to ensure that addresses are properly typed.

While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security.[81] Regulators in several countries have warned against cryptocurrency and some have taken concrete regulatory measures to dissuade users.[82] Additionally, many banks do not offer services for cryptocurrencies and can refuse to offer services to virtual-currency companies.[83] Gareth Murphy, a senior central banking officer has stated "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy.[84] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen.[85] One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.

Litecoin was released via an open-source client on GitHub on October 7, 2011 by Charlie Lee, a Google employee and former Engineering Director at Coinbase.[2][3] The Litecoin network went live on October 13, 2011. It was a fork of the Bitcoin Core client, differing primarily by having a decreased block generation time (2.5 minutes), increased maximum number of coins, different hashing algorithm (scrypt, instead of SHA-256), and a slightly modified GUI.

A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.[1][2][3] Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems.[4]
