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]

As of May 2018, over 1,800 cryptocurrency specifications existed.[24] Within a cryptocurrency system, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners: who use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[14]

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.

As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada.[32] One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices.[33] In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 MW to crypto companies for mining.[34] According to a February 2018 report from Fortune,[35] Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity. Prices are contained because nearly all of the country's energy comes from renewable sources, prompting more mining companies to consider opening operations in Iceland.[citation needed]

In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[7][8] Later, in 1995, he implemented it through Digicash,[9] an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.
J. P. Morgan Chase is developing JPM Coin on a permissioned-variant of Ethereum blockchain dubbed "Quorum".[52] It's designed to toe the line between private and public in the realm of shuffling derivatives and payments. The idea is to satisfy regulators who need seamless access to financial goings-on, while protecting the privacy of parties that don't wish to reveal their identities nor the details of their transactions to the general public.[53]
Las cadenas de bloques son seguras por diseño y son un ejemplo de sistema distribuido con un alta tolerancia a faltas bizantinas. El consenso descentralizado ha sido logrado gracias a la cadena de bloques. Las cadenas de bloques resuelven el problema de doble gasto sin la necesidad de una autoridad certificada o un servidor central, asumiendo que no se va a dar el ataque del 51% (que ha funcionado con varias criptomonedas).

As with other cryptocurrencies, the validity of each ether is provided by a blockchain, which is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[30][31] By design, the blockchain is inherently resistant to modification of the data. It is an open, distributed ledger that records transactions between two parties efficiently and in a verifiable and permanent way.[32] Unlike Bitcoin, Ethereum operates using accounts and balances in a manner called state transitions. This does not rely upon unspent transaction outputs (UTXOs). State denotes the current balances of all accounts and extra data. State is not stored on the blockchain, it is stored in a separate Merkle Patricia tree. A cryptocurrency wallet stores the public and private "keys" or "addresses" which can be used to receive or spend ether. These can be generated through BIP 39 style mnemonics for a BIP 32 "HD Wallet". In Ethereum, this is unnecessary as it does not operate in a UTXO scheme. With the private key, it is possible to write in the blockchain, effectively making an ether transaction.

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.

“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.

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]

According to PricewaterhouseCoopers, four of the 10 biggest proposed initial coin offerings have used Switzerland as a base, where they are frequently registered as non-profit foundations. The Swiss regulatory agency FINMA stated that it would take a "balanced approach" to ICO projects and would allow "legitimate innovators to navigate the regulatory landscape and so launch their projects in a way consistent with national laws protecting investors and the integrity of the financial system." In response to numerous requests by industry representatives, a legislative ICO working group began to issue legal guidelines in 2018, which are intended to remove uncertainty from cryptocurrency offerings and to establish sustainable business practices.[50]

Although there are some similarities between BTC and LTC, you can’t define Litecoin without pointing out some key differences, such as instant and near-zero cost transactions, increased speed of adding a new block into the Blockchain (2.5 minutes against 10 in the Bitcoin network) and a scrypt usage in its Proof-of-Work process to make it easier for regular PC users to mine new blocks against ASIC miners. It is also one of the first cryptocurrencies that adopted SegWit.

Here’s why. Ethereum is based on blockchain technology where all transactions are meant to be irreversible and unchangeable. By executing a hard fork and rewriting the rules by which the blockchain executes, Ethereum set a dangerous precedent that goes against the very essence of blockchain. If the blockchain is changed every time a large enough amount of money is involved, or enough people get negatively impacted, the blockchain will lose its main value proposition – secure, anonymous, tamper proof & unchangeable.

Bitcoin es seudónimo en vez de anónimo, ya que la criptomoneda dentro de una cartera no está vinculada a las personas, si no a una más claves específicas.

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 term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"[20] while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.[21] Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins.[22]
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.

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”.

Litecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Litecoin is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances. Litecoin features faster transaction confirmation times and improved storage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.
Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is not tied to people, but rather to one or more specific keys (or "addresses").[41] Thereby, bitcoin owners are not identifiable, but all transactions are publicly available in the blockchain. Still, cryptocurrency exchanges are often required by law to collect the personal information of their users.[citation needed]

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 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.

Las criptomonedas hacen posible el llamado internet del valor, también conocido por las siglas IoV (del inglés internet of value), también llamado Internet del dinero: son aplicaciones de Internet que permiten el intercambio de valor en forma de criptomonedas. Este valor pueden ser contratos, propiedad intelectual, acciones o cualquier propiedad de algo con valor. Las cosas de valor ya se podían intercambiar antes usando sistemas de pago como Paypal. Sin embargo la diferencia entre pagar con algo como Paypal y pagar con una criptomoneda consiste en que pagar con Paypal requiere que el pago se haga a través de redes privadas como las de las tarjetas de crédito y bancos, mientras que el pago usando criptomonedas no tiene intermediarios. Va directamente del comprador al vendedor. De esta forma, se tiene un sistema de transferencia universal de valor, libre de intermediaciones.
