Ethereum tiene una ventaja fundamental sobre Bitcoin

Un grupo de investigadores de la Universidad de Cornell en Nueva York (Estados Unidos) ha publicado esta semana un documento titulado Descentralización en Bitcoin y Ethereum, en el que compara, valga la redundancia, la descentralización de las dos redes de criptodivisas más grandes por capitalización de mercado.

Ethereum vs. Bitcoin

La investigación de dos años dirigida por el profesor de Cornell Emin Gun Sirer y que incluye al profesor de investigación de Cornell Robbert van Renesse y al investigador de LinkedIn Adem Efe Gencer concluye que los nodos de Ethereum están mejor distribuidos que los de Bitcoin y, por tanto, la red que maneja ethers está más descentralizada.

También destaca que ninguna de las dos blockchain está tan descentralizada en la práctica como se planteaba en la teoría -la crítica a este punto ha sido que se refiere más bien solo a la minería en ambas cadenas-. Además, que las recompensas para los mineros más pequeños de Bitcoin son frecuentemente menos predecibles que para los de Ethereum.

Latencia y ubicaciones geográficas

El estudio analiza los nodos de ambas basándose en la latencia de cada red y sus ubicaciones geográficas. Con base en estos dos criterios, el estudio reveló que la red de Ethereum está más descentralizada debido a que los nodos están mejor distribuidos a nivel global, pues demuestran que hay menos nodos concentrados en centros de datos como ocurre con Bitcoin.

"Los nodos de Ethereum no se acumulan en una sola región geográfica, sino que están distribuidos de manera más uniforme en todo el mundo… Los nodos de Ethereum están geográficamente más separados que los de Bitcoin", indica el estudio. De hecho, Ethereum procesa cuatro veces el número de transacciones de Bitcoin a magnitudes más bajas con mucha menos congestión.

El análisis sobre la distribución de los nodos a través del ping de la latencia también midió cuánto tardaría un nodo en responder a un “comando”. La investigación encontró que solo el 13% de las latencias de Ethereum tienen menos de 100 milisegundos (ms, el tiempo que tardan en comunicarse una conexión local con un equipo remoto en la red IP), mientras que Bitcoin tiene 46%. Además, la latencia estimada de igual a igual (Peer-To-Peer o P2P) entre los nodos de Ethereum es 26,7% más alta que Bitcoin en promedio. Esta proximidad entre la ubicación de los nodos, así como el hallazgo de que Bitcoin tiene muchos más nodos abastecidos con 100 Mbps de ancho de banda, es lo que sugiere a los investigadores que una gran cantidad de nodos de Bitcoin se ejecutan en centros de datos, como explican en el texto:

Parte de la razón de esto es que un porcentaje mucho más alto de nodos de Bitcoin reside en los centros de datos. Específicamente, solo el 28% de los nodos de Ethereum se puede identificar positivamente que está en centros de datos, mientras que el mismo número para Bitcoin es del 56%. Los nodos que residen en los centros de datos pueden indicar un mayor nivel de corporatización. También pueden ser un síntoma de nodos desplegados para sesgar los recuentos de nodos para diversas implementaciones diferentes.

Seguridad

Los investigadores examinaron los nodos y su interconexión, los requisitos de protocolo y la forma en que resisten los ataques, utilizando la red de retransmisión de Falcon (FRN, por sus siglas en inglés) para recopilar datos. Muchas de las críticas en contra de la red de Ethereum han sido relacionadas a sus supuestas medidas de seguridad y una descentralización inferior en comparación con Bitcoin. Sin embargo, la investigación de Cornell reveló que, en términos de seguridad y descentralización, Ethereum está a la par o incluso mejor que la red de Bitcoin.

Minería y tasa de hash

En cuanto a la minería, el estudio señala que tanto Ethereum como Bitcoin no están "tan descentralizados". El profesor Sirer, líder del estudio de Cornell, abundó al respecto de este punto en la investigación en su blog explicando que la minería en Ethereum y Bitcoin está muy centralizada, ya que los grupos que controlan los centros de minería ostentan el poder de la tasa de hash (la unidad de medida de la potencia de procesamiento de la red Bitcoin). En las operaciones mineras, cuando la red alcanza un hash rate de 10 TH/s significa que puede hacer 10 billones de cálculos por segundo.

En Bitcoin y los tres principales mineros en Ethereum controlan más del 50% de la tasa de hash. La cadena de blockchain entera en ambos sistemas está determinado por menos de 20 entidades mineras. Por lo tanto, vemos que se requiere hacer más investigación sobre esta área para desarrollar protocolos de consenso sin permiso que también sean eficientes desde el punto de vista energético".

El estudio también sugiere que Ethereum es más justo que Bitcoin con los mineros más pequeños debido a que tiene una varianza más predecible, lo que permite a los mineros más pequeños tener un flujo de ingresos más constante. Ethereum tiene una frecuencia de bloqueo más alta que Bitcoin, así que los mineros más pequeños tienen una rentabilidad más predecible que los mineros más grandes. Es por esto que Ethereum es más predecible para los mineros más pequeños debido a una menor varianza en las recompensas por bloques. Pero los autores del estudio señalan que la minería de Ethereum podría ser más eficiente y de mayor capacidad si incorpora una red de retransmisión como Falcon o FIBER.

Conclusión

La centralización de la minería en ambas redes es refutable basándonos en la premisa de que los mineros individuales también contribuyen a los fondos mineros. Es decir, que estos grupos ostenten el poder de la tasa de hash no importa porque los mineros individuales se pueden cambiar en cualquier momento a otras redes y, por tanto, llevarse consigo su poder de cómputo a otro lado.

La postura de la comunidad de Ethereum es más experimental y arriesgada frente a la de Bitcoin, lo que ha llevado a desarrollar blockchains fundamentalmente diferentes. Los desarrolladores de Bitcoin están experimentando actualmente con Lightning, una solución de canal de micropagos, mientras que los de Ethereum están probando soluciones más innovadoras como ZK-SNARK para potencialmente resolver transacciones anónimas y privadas; Plasma, una infraestructura más robusta para soportar más información; Sharding, un proyecto en cuanto a los nodos que aún está proceso, y Casper, un protocolo para el proceso de consenso entre la red. Será interesante ver un estudio comparativo sobre la descentralización una vez que Casper pase su prueba de fuego con Ethereum y sea incorporada al 100%.

Ethereum Surges 15% to New Historic High, Trading Over $1,800 in South Korea

Get Trading Recommendations and Read Analysis on Hacked.com for just $39 per month.

The price of Ether, the native cryptocurrency of Ethereum, has surged by more than 15 percent overnight, achieving a new all-time high at $1,266.

New All-Time High at $1,266

Four days ago, on January 4, CCN previously reported that the price of Ether established a new all-time high at $1,000, surpassing the $1,000 for the first time in its two-year history. The market valuation of Ethereum surpassed a staggering $100 billion, becoming the third cryptocurrency to do so apart from bitcoin and Ripple.

Merely four days later, on January 8, Ether demonstrated another major increase in value, reaching $1,266 across all global exchanges such as Binance and Bittrex.

The latest rally of Ether has been led by the South Korean market and leading cryptocurrency exchanges within it, including Bithumb, Korbit, and Coinone. Within the South Korean global market, the price of Ether surpassed $1,800, demonstrating a $534 premium over the global average price. That is, a 29.6 percent premium over the global average Ether price.

On Bithumb, the Seoul-based cryptocurrency exchange which recently became the second largest trading platform behind Binance, Ethereum is the third most traded cryptocurrency with a $378 million daily trading volume.

Cryptocurrencies on Bithumb, South Korea’s largest exchange

No specific event or movement has led to the increase in the price of Ether over the past few days. The transaction volume and developer activity of Ethereum have been on the rise in general, given that the Ethereum network is currently settling more than 1.2 million transactions per day. The rise in the user activity on the Ethereum network could have led to the price increase of Ether in the short-term.

But, in consideration of the abrupt surge in demand from the South Korean market, it is likely that FOMO or fear or missing out drove the recent price surge of Ether, as the South Korean cryptocurrency exchange market is strongly driven by FOMO.

One minor factor that could have also triggered an increase in demand for Ether is the rise of adoption of decentralized applications like CryptoKitties and EtherDelta that have demonstrated the potential of Ethereum in peer-to-peer digital asset trading.

Arbitrage? Think Again

Although the price of cryptocurrencies in the South Korean market is significantly higher than the global average rates, it is not possible for foreigners to take advantage of the arbitrage opportunity in the South Korean market for many reasons:

Investors need mobile phone numbers to register on South Korean exchanges. South Korean telecoms do not issue (even prepaid sim cards) to individuals without Korean citizenship, residential visa, or work visa.
Investors need bank accounts. But, banks do not open bank accounts to foreigners without residential or work visa. Banks make it hard for citizens to open accounts as well, due to the governments’ recent crackdown on offshore banking accounts and fraudulent bank accounts.
The South Korean government has banned foreigners and underaged investors from investing in cryptocurrencies. South Korean cryptocurrency exchanges cannot accept foreigners into their trading platforms.

Conclusively, the prices of cryptocurrencies in the South Korean market are high because of capital controls. The South Korean market is isolated from the global market and foreigners are not allowed in it. Conversely, South Korean traders cannot open accounts overseas without proper paperwork.

Ethereum scammers disguised as Vitalik Buterin are out to steal your coins

You might want to be extra suspicious in case you receive an email from Ethereum founder Vitalik Buterin, cordially asking you to send money: chances are someone is trying to scam you out of your funds.

Buterin has taken to Twitter to warn his followers that malicious actors are pretending to be him in order to trick unsuspecting cryptocurrency rookies into sending them their coins.

“If you get an email that looks like it’s from me asking for ETH, please do NOT send,” the founder cautioned. “Either contact me first or if you’re lazy just assume it’s a fraud.”

If you get an email that looks like it's from me asking for ETH, please do NOT send. Either contact me first or if you're lazy just assume it's a fraud.

— Vitalik Buterin (@VitalikButerin) January 22, 2018

As Buterin goes on to explain, the scammers – posing as him – claim his “laptop literally died” before proceeding to ask for funds – until he has had a chance to access his “cold wallet a week from now.”

Perhaps due to its growing popularity, the cryptocurrency space is flush with various scams and phishing traps these days.

Earlier in January, there were tons of suspicious copycats of popular exchange desk Binance on Google. The majority of these pages were designed to forward visitors to the official Binance site – but via a referral link.

Those curious to investigate some of the active cryptocurrency scams on the internet ought to check out the Ethereum Scam Database here.

Meanwhile, don’t get too excited if you get some mail from Buterin: it’s about as special as getting an investment opportunity from a Nigerian prince.

Stay tuned for the launch of our new channel, Hard Fork, where we will be taking a deep dive into everything cryptocurrency and blockchain.

Ethereum Rises in a Sea of Red

Ethereum has reached a new all-time high today of $1,200 per coin just days after it broke that big $1,000 for the first time.

While its trading volumes have increased considerably above $7 billion, with trading pairs seemingly equally spread between BTC, South Korean Won and the dollar.

The currency now has retaken second position with its market cap rising to $114 billion while Ripple has nearly halved to $86 billion.

Much of everything else is down, including bitcoin, while ETH has gained a bit, quickly recovering from a brief sell-off to just below $1,000 to currently trade at $1,160.

There has been no specific news as far as we are aware to propel this rise which began after the announcement Casper had entered testnet.

That’s the last stage of the process before implementation into the live network which might perhaps be expected by summer.

The market, therefore, might be accumulating in anticipation because once Casper launches then ethereum becomes an interest bearing asset, paying dividends like stocks.

That would make ethereum unique among the top digital currencies as it would be the only one to grow the invested capital in eth itself.

The actual details are not finalized as far as we are aware, but you’d probably need quite a bit of eth to stake, in the process so securing the network and earning interest through mining like staking.

But, it is probable the amount doesn’t hugely matter as staking pools would probably rise for the little guys, although it would likely be preferable if solo staking is most accessible to increase decentralization as pools can have significant influence.

The other unfinalized parameter is the level of interest, which for non stakers means the level of inflation. You’d hope it would eventually settle at around 1%-2% a year as that would probably be a level that kind of keeps it at zero due to lost coins, but we’ll have to wait and see what is decided.

The initial implementation of Casper will be a hybrid Proof of Stake/Proof of Work, so miners will still be around, but gradually they will be phased out fully, with ethereum so transitioning to operate from just laptops, without requiring specialized hardware.

No top currency has operated in this manner, therefore few can predict with certainty how exactly incentives will change, but the upgrade will be one of the biggest, to be topped only by Sharding once that comes hopefully by 2020.
