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. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. 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". 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 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 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.

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.

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.
LTC is a tricky one to predict. Consider that LTC has been leading the way earlier this year and not BTC. Although BTC gets the news, LTC was usually the first to move (pump) with BTC then eth/alts. LTC topped out June 22 '19 with BTC following June 26 '19. While BTC is playing more of a traditional DOW theory thus far (and I use traditional in the loose sense...
