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.

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.

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]

In 1998, Wei Dai published a description of "b-money", characterized as an anonymous, distributed electronic cash system.[12] Shortly thereafter, Nick Szabo described bit gold.[13] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.[citation needed]

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.

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.

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.

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. Por lo tanto, los usuarios de los bitcoin no son identificables, pero todas las transacciones están públicamente en la cadena de bloques. Sin embargo, la ley exige a menudo que los intercambios de criptomonedas recaben información personal de sus usuarios.
Welcome to the 32nd Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of ExchangeCoin. This will be comprised of an analysis of a number of significant metrics, an evaluation of the project’s community and development and an overview of its price-history. The report will conclude with a grading out of 10. ExchangeCoin was launched in November 2017 with an ICO that raised 650 BTC, equating to over $5,000,000 at the time. The token issued, EXCC, has a maximum supply of 32,003,133, with 4mn EXCC sold during the ICO. Further, the project also has a premine of 12.1mn EXCC, equating to 37.95% of the maximum supply (from which the 4mn was sold to the public in the token sale). The token itself operates on the Equihash algorithm, and underwent a hard fork in July 2018, after which the network migrated to a dual Proof-of-Work/Proof-of-Stake consensus mechanism, with 30% of block rewards rewarded to stakers and 70% to miners. The block reward is progressively diminishing, with the current reward at 24.5 EXCC per block, with 2.5-minute block times.

The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.[16]

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.

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.

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]
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).

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​

In October 2015,[62] a development governance was proposed as Ethereum Improvement Proposal, aka EIP, standardized on EIP-1.[63] 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)[64] and EIP-20 (ERC-20 Token Standard).[65] In January 2018, the EIP process was finalized and published as EIP-1 status turned "active".[62] Alongside ERC-20, notable EIPs to have become finalised token standards include ERC-721[66] (enabling the creation of non-fungible tokens, as used in Cryptokitties) and as of June 2019, ERC-1155 [67] (enabling the creation of both fungible and non-fungible tokens within a single smart contract with reduced gas costs).

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]

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.

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.

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‘.

En las redes de criptomonedas, el minado es una validación de las transacciones. Por este esfuerzo, los mineros obtienen unidades como recompensa. Esta recompensa disminuye las tarifas, creando un incentivo complementario para contribuir al poder de procesamiento de la red. El ratio de generar nuevos hashes que validan cualquier transacción ha ido aumentado por el uso de máquinas especializadas como FPGAs y ASICs. Esta carrera por máquinas baratas y eficientes ha existido desde los días de la primera criptomoneda, bitcoin, que fue introducida en 2009. Cuantas más personas se han ido aventurando en el mundo de las criptomonedas, la complejidad de la generación hashes ha ido aumentando a lo largo de los años, haciendo que los mineros tengan que invertir grandes cantidades de dinero en máquinas especializadas. Algunas veces, el valor de las unidades obtenidas no justificaban la inversión en máquinas, la refrigeración de estas y la energía consumida para hacerlas funcionar.20​

After much debate, the Ethereum community voted and decided to retrieve the stolen funds by executing what’s known as a hard fork or a change in code. The hard fork moved the stolen funds to a new smart contract designed to let the original owners withdraw their tokens. But this is where things get complicated. The implications of this decision are controversial and the topic of intense debate.

Ethereum is the pioneer for blockchain based smart contracts. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. On the blockchain, smart contracts allow for code to be run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. The Ethereum network went live on July 30th, 2015 with 72 million Ethereum premined.

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]

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”.
