Any services that are centralized can be decentralized using Ethereum. Think about all the intermediary services that exist across hundreds of different industries. From obvious services like loans provided by banks to intermediary services rarely thought about by most people like title registries, voting systems, regulatory compliance and much more.

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]
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.
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]

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

Las ofertas iniciales de monedas (ICO, en inglés) es un medio controvertido para recaudar fondos para una criptomoneda. Las empresas nuevas pueden utilizar un ICO con la intención de evitar la regulación. Sin embargo, los reguladores de valores en muchas jurisdicciones, incluso en los EE.UU. y Canadá han indicado que si una moneda o ficha es un "contrato de inversión" (por ejemplo, bajo la prueba de Howey, es decir, una inversión de dinero con una expectativa razonable de ganancias). significativamente en los esfuerzos empresariales o de gestión de otros), es una seguridad y está sujeta a la regulación de valores. En una campaña de ICO, un porcentaje de la criptomoneda (generalmente en forma de "fichas") se vende a los patrocinadores tempranos del proyecto a cambio de moneda legal u otras criptomonedas, a menudo bitcoin o éter.26​27​28​

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.

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.
Ethereum was initially described in a white paper by Vitalik Buterin,[10] a programmer involved with Bitcoin Magazine, in late 2013 with a goal of building decentralized applications.[11][12] Buterin had argued that Bitcoin needed a scripting language for application development. Failing to gain agreement, he proposed development of a new platform with a more general scripting language.[4]:88

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.

The novel hybrid consensus-based TrueChain tends to rely on POW consensus for random node selection, instead of using the slow chain mechanism to ensure security like Thunder.Although TrueChain has released dozens of Dapps, the number of its addresses (including active ones)and transactions is small. After the mainnet is launched, the project has run out of short-term bullish factors, which, plus the underdevelopment of its ecosystem, leads to a price slump within a short period of time. It will take some time for investors to regain confidence.

Litecoin, however, uses the scrypt algorithm – originally named as s-crypt, but pronounced as ‘script’. This algorithm incorporates the SHA-256 algorithm, but its calculations are much more serialised than those of SHA-256 in bitcoin. Scrypt favours large amounts of high-speed RAM, rather than raw processing power alone. As a result, scrypt is known as a ‘memory hard problem‘.

On May 7, 2019, Binance revealed that it had been the victim of a “large scale security breach” in which hackers had stolen 7,000 Bitcoin worth around U.S.$40 million at the time.[11] Binance CEO Changpeng Zhao said the hackers “used a variety of techniques, including phishing, viruses and other attacks” and structured their transaction “in a way that passed our existing security checks.”[12] Binance halted further withdrawals and deposits but allowed trading to continue. The site pledged to reimburse customers through its secure asset fund.

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.

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]

Properties of cryptocurrencies gave them popularity in applications such as a safe haven in banking crises and means of payment, which also led to the cryptocurrency use in controversial settings in the form of online black markets, such as Silk Road.[66] The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[66]
“A DAO consists of one or more contracts and could be funded by a group of like-minded individuals.

An initial coin offering (ICO) is a controversial means of raising funds for a new cryptocurrency venture. An ICO may be used by startups with the intention of avoiding regulation. However, securities regulators in many jurisdictions, including in the U.S., and Canada have indicated that if a coin or token is an "investment contract" (e.g., under the Howey test, i.e., an investment of money with a reasonable expectation of profit based significantly on the entrepreneurial or managerial efforts of others), it is a security and is subject to securities regulation. In an ICO campaign, a percentage of the cryptocurrency (usually in the form of "tokens") is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often bitcoin or ether.[47][48][49]

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.
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.[41]

Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto.[23]
Romper la seguridad existente en una criptomoneda es matemáticamente posible, pero el costo para lograrlo sería inasumiblemente alto. Por ejemplo, un atacante que intentase quebrar el sistema de prueba de trabajo de Bitcoin necesitaría una potencia computacional mayor que el de todo el entramado (red-enjambre) de todos los mineros del sistema, y aun así, solo tendría una probabilidad de éxito del 50% (n.º de ronda de autenticación), en otras palabras, romper la seguridad de Bitcoin exigiría una capacidad superior a la de empresas tecnológicas del tamaño de Google.6​

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.
