Hugh Karp’s PC was compromised before the attack.

MetaMask browser extension has been replaced with a malicious application.

Ledger users are now the target of similar personal attacks

The founder of the DeFi insurance protocol Nexus Mutual published a post-mortem on a targeted attack using MetaMask that resulted in the personal loss of $ 8 million in crypto assets.

On December 14 , Hugh Karp, founder of Nexus Mutual, had an unpleasant surprise when he was led to make a transaction to an attacker’s address via MetaMask. This resulted in the loss of 370,000 Nexus Mutual (NXM) tokens, worth approximately $ 8.4 million at the time.

Karp has now detailed the attack in the hopes that others will not fall victim to the same hack.

A post-mortem and update on the status of the hack in NXM from last week.

Thank you to everyone for your messages of support, and especially to those who contributed to our surveys.

PC Windows and MetaMask compromis

The DeFi expert said he was then using a Ledger connected through MetaMask to interact with the Nexus Mutual app, on a computer running Microsoft Windows.

A few days earlier, Karp had noticed a screen flickering while composing an email, but didn’t pay much attention to it. An hour later, on December 11, the MetaMask extension was modified from disk and replaced with a malicious version.

On the day of the attack, he went to claim mining rewards through the MetaMask extension, which revealed a fraudulent transaction instead of a transaction to the intended destination. The transaction appeared in the Ledger and was completed, but there was no confirmation from the Nexus Mutual app. It was then that the attack was finalized.

Vuonna 2017 suunniteltu suhteellisen tuntematon salaustekniikka vain näki sen markkina-arvon nousevan yli 500 miljoonaan dollariin alle 48 tunnissa käynnistämisen jälkeen.

Graafi (GRT) on Ethereum-pohjainen indeksointiprotokolla, jonka avulla käyttäjät voivat kysellä tietoja lohkoketjusta hajautetusti. Ennen The Graphin olemassaoloa tiimien oli erittäin vaikeaa saada korkealaatuista tietoa lohkoketjusta.

”Ennen The Graphia tiimien oli kehitettävä ja käytettävä omia indeksointipalvelimia. Tämä vaati merkittäviä suunnittelu- ja laitteistoresursseja ja hajosi hajauttamisen edellyttämät tärkeät turvaominaisuudet. „

Web 3.0: n Googleksi kutsuttu Graafi perustuu yksilöiden verkostoon, jotta kuluttajat tai loppukäyttäjät voivat käyttää tehokkaasti blockchain-tietoja. Indeksoijat ovat solmuoperaattoreita, jotka panostavat GRT: hen tarjoamaan palveluja, kuten indeksointi ja kyselyjen käsittely. Ne tuottavat tuloja kyselymaksuista bruttorekisteritonnina.

Delegaattorit ovat henkilöitä, jotka eivät halua käyttää solmuja, mutta voivat silti myötävaikuttaa verkon turvallisuuteen panostamalla GRT: tä indeksoijan puolesta. Palveluistaan he ansaitsevat osan indeksointipalkkioista.

Kuraattorit ovat yleensä kehittäjiä, jotka käyttävät GRT: tä ilmoittaakseen indeksoijille, mitkä API: t tai alikaaviot tulisi indeksoida protokollan avulla.

Graafin tekniikkaa käytetään jo huippuluokan hajautetun rahoituksen (DeFi) hankkeisiin, mukaan lukien hajautettu vaihto Uniswap (UNI), johdannaisten kaupankäyntialusta Synthetix (SNX) ja lainanantoprotokolla Aave.

Tunnin kuluttua 18. joulukuuta käynnistymisestä GRT: n markkina-arvo nousi 165 miljoonasta 521 miljoonaan dollariin 19. joulukuuta. Hinnan suhteen GRT nousi nousuun 0,135 dollarista laukaisupäivänä jopa 0,569 dollariin 19. joulukuuta, mikä tarkoittaa yli 321 prosentin nousua 48 tunnin jaksossa.

Näkyvä salausanalyytikko ja kauppias Josh Rager kertoo jo 94700 seuraajalleen, että heidän tulisi seurata tarkasti GRT: tä.

”Kiinnitä huomiota GRT: hen. DeFi + todellinen toimiva tuote. Monet eivät ymmärrä GRT: tä tai sitä, että Uniswap toimii tällä hetkellä The Graphilla. Jo listattu huippupörsseihin – GRT: n potentiaali on helppo nähdä suurena DeFi-soittimena. „

Flare jakaa 45827728412 kipinämerkkiä XRP-haltijoille

Ripple-tukema salauksen käynnistys Flare seuraa, kuinka monta Spark-tunnusta se laskee XRP-sijoittajille vuoden 2021 ensimmäisellä puoliskolla.

Tunnus on osa uutta älykästä sopimusekosysteemiä, joka on suunniteltu tuomaan Ethereum-tyyppiset toiminnot XRP Ledgeriin.

Sen jälkeen kun otit otoksen XRP Ledgeristä viime viikolla kaikkien elinkelpoisten tilien määrittämiseksi, yritys on käynyt läpi tuloksia selvittääkseen, kuinka monta merkkiä se jakaa.

Suoritettuaan matematiikan ja sulkenut Spark-merkit salausvaihdoista, jotka päättivät olla tukematta maapalloa, Flare sanoo laskevansa XRP-omistajille yhteensä 45 827 728 412 merkkiä.

Flare korostaa, että se ei anna Spark-tunnuksia Ripplelle, jolla on noin 54172 271 587 XRP julkaisuhetkellä.

Flare antaa kuitenkin Spark-rahakkeita XRP-tileille, jotka on omistettu Ripple-perustajan Chris Larsenin perustamalle hyväntekeväisyysjärjestölle Rippleworks.

Varat jaetaan nopeudella 1 XRP – 1,0073 Spark.

Tulevaa ilmapisaraa tukee kymmeniä kryptovaluutanvaihtoa, ja sen on määrä tapahtua ensi vuoden alussa, kun Flare-verkko on käynnissä.

CoinTrackerin verostrategiapäällikön mukaan lentorata aiheuttaa verovelvollisuuden Yhdysvaltain kansalaisille.

Bitcoin (BTC) ha continuado su ascenso después de finalmente romper los $ 20,000, alcanzando un máximo de $ 23,800 el 17 de diciembre.

Se espera que Bitcoin continúe aumentando hacia objetivos más altos antes de una eventual corrección.

Bitcoin resuena

El precio de BTC ha continuado su movimiento ascendente después de superar los $ 19,500. Ayer alcanzó un máximo de $ 23,800 antes de crear una pequeña mecha superior y disminuir ligeramente a $ 23,000.

Los indicadores técnicos en el marco de tiempo diario son alcistas. Además del hecho de que el movimiento de ayer ocurrió con un volumen significativo, el RSI acaba de cruzar de nuevo por encima de 70 y el histograma MACD ahora es positivo. La continuación de la tendencia alcista sería confirmada por un cruce alcista en el oscilador estocástico.

Ikke-vestlige børser er noe av et tabuemne i kryptovalutaverdenen. Høsten til den japansk-baserte Mt. Gox og den nylige klemmen på kryptohandel av kinesiske, indiske og koreanske myndigheter fikk den gjennomsnittlige brukeren til å tenke seg om før han gjorde sin virksomhet utenfor USA / Europa. Likevel, mange mennesker gleder seg over lax (er) reguleringen og lavere avgifter som disse „utenforstående“ gir, noe som gjorde Bithumb, en koreansk børs, til en av verdens mest populære plattformer for kryptohandel.

Bithumb er basert i Seoul, Sør-Korea

Grunnlagt i 2013, eies og drives det av et selskap som heter BTC Korea.Com Co. Ltd. Bloomberg-profilen for selskapet nevner ingen ledere, styremedlemmer eller andre data om selskapet. Denne utvekslingen lar brukerne kjøpe, selge og lagre Bitcoin i tillegg til en rekke andre kryptovalutaer.

Det har nylig kjempet en krig med Upbit for tittelen på Koreas nummer én kryptovalutautveksling . De daglige handelsvolumene går nesten regelmessig over en milliard dollar i verdi, og plasserer denne børsen blant de 10 beste verdensbørsen volummessig. Nylig kom en rapport som antydet at mengden 24-timers transaksjoner på Bithumb sto på 3,48 billioner vunnet (3,27 milliarder dollar), og tallet nådde 8,4 billioner vunnet (7,89 milliarder dollar) når det ble kombinert med Upbit.

Det er langt mer enn noe annet land med tanke på at daglige transaksjoner i Hong Kong (som har to børser på topp 10-listen i verden) beløp seg til 6,3 billioner vunnet (US $ 5,92 milliarder), mens de i Kina la opp til 3,7 billioner vant (US $ 3,47 milliarder dollar). I 2017 rapporterte Korea Herald at Bithumb utgjorde omtrent 10% av den globale Bitcoin-handelen. Denne prosentandelen har gått ned nå med andre valutaer som tar over sin andel av handelsvolumet. Likevel er Bithumb fortsatt en betydelig aktør i Bitcoin-markedet, med daglige Bitcoin-handelsvolum når hundrevis av millioner dollar. Børsen siteres jevnlig som ansvarlig for omtrent halvparten av Sør-Koreas Ethereum-handel.

Regulering

Som med alle koreanske plattformer, er Bithumb underlagt noe lovlig overvåkning fra Sør-Koreanske Financial Services Commission (FSC), Korean Fair Trade Commission (KFTC), National Tax Service (Korean IRS) og politiet. Sør-Korea planlegger å gjøre en regjeringsinnsats for å styrke kryptoreglementet. Under et intervju med lokalradiostasjonen TBS sa visestatsminister og finansminister Kim Dong-yeon: „Forslaget om å stenge kryptokursutveksling er fortsatt et alternativ under behandling,“ og vekker opp kontroversen om nedleggelse av børsene igjen.

„Det er mange urimelige og spekulative transaksjoner i digitale valutaer, så myndighetene mener at det er nødvendig med rimelige regler i noen form,“ sa Kim. Ettersom store land i verden, inkludert Sør-Korea, søker å komme med strengere regulering, har markedene opplevd en nedgang. Likevel viste et nylig vitnesbyrd fra amerikanske SEC og CFDC foran det amerikanske senatet at den amerikanske regjeringen ikke vil stenge kryptovalutahandelen helt.

Snarere tar de sikte på å regulere det til beste for alle. Siden USA vanligvis er diktatoren for verdens finanspolitikk, forventes det at andre land, spesielt amerikanske allierte som Sør-Korea, vil følge etter.

La demanda de intercambio de hackers de Mt. Gox podría concluir pronto con 140.000 Bitcoin distribuidos a antiguos usuarios.

Llaves para llevar

• La fecha límite de distribución de las existencias de criptocultura asociadas al caso de Mt. Gox está prevista para el 15 de diciembre.
• El „plan de rehabilitación“ implica la asignación de casi 140.000 Bitcoin a los usuarios que perdieron fondos durante la quiebra del intercambio.
• Valorados en 2.600 millones de dólares hoy, los mercados podrían volverse potencialmente bajistas si una oleada de receptores optan por vender su Bitcoin.

En una semana, la saga del intercambio de Mt. Gox podría finalmente concluir. El 15 de diciembre, una asignación estimada de 137.891 BTC se distribuirá a los usuarios que perdieron fondos tras el cierre de Mt. Gox en 2014.

El tan esperado pago de Mt. Gox

El cierre del Monte Gox es uno de los eventos más infames en la historia de las cadenas de bloqueo y las criptocracias. La bolsa japonesa cesó abruptamente sus operaciones en febrero de 2014, anunciando que había perdido 850.000 BTC en varios ataques.

Bitcoin era una de las pocas criptodivisas establecidas en ese momento, y Mt. Gox era responsable de manejar alrededor del 70% de sus transacciones.

El evento causó que varios de los primeros inversores de Bitcoin perdieran sus participaciones. Sigue siendo fundamental para el mantra a menudo repetido de la comunidad criptográfica „ni sus llaves, ni sus monedas“, que aconseja a los inversores no almacenar sus fondos en un intercambio centralizado.

Preocupaciones sobre la reacción del mercado

El próximo evento de distribución verá el alijo de Bitcoin recuperado por valor de 2.600 millones de dólares ir a un número de antiguos usuarios de Mt. Gox. Bitcoin sólo estaba cotizando a unos 700$ cuando Mt. Gox detuvo todas las retiradas en febrero de 2014. Se ha visto un aumento en el valor de aproximadamente 2600% desde entonces, lo que podría ser una ganancia inesperada para los receptores.

Debido al significativo aumento de valor desde 2014, es posible que varios destinatarios puedan vender su Bitcoin recién recibido en el mercado abierto. Eso podría crear un panorama pesimista si el sentimiento cambia repentinamente como resultado de la distribución. Los miembros de „Crypto Twitter“ han manifestado su preocupación por el plazo pendiente.

Mucha anticipación

Un número de seguidores de la criptografía han estado monitoreando cuentas que se sospecha son controladas por los directores de Mt. Gox, sin duda con un mayor escrutinio a medida que se acerca el plazo del 15 de diciembre. Se están llevando a cabo discusiones sobre un subreddit llamado /r/mtgoxinsolvency, y un sitio web está específicamente dedicado a rastrear transacciones relevantes. Hasta ahora, sin embargo, la actividad está latente.

En cualquier caso, el evento proporcionará un cierre, ya que la fecha del plan de rehabilitación del Monte Gox se ha retrasado varias veces. La fecha del 15 de diciembre fue confirmada por primera vez en octubre pasado.

Human DeFi Haeck will take place remotely from 10 November to 10 December

Human DeFi Haeck is an initiative that wants to contribute to bringing the advantages of DeFi to a more people-centred perspective. It will take place remotely from 10 November to 10 December. This was reported to Cointelegraph en Español in a press release.

This hackathon is an initiative of æternity blockchain and superhero.com, a decentralised social network built on æternity.

In the release they also detailed some of the features of æternity, the Erlang-based blockchain: „Integrated oracles, unlimited scalability and low transaction fees“.

„The haeckathon will run remotely on devpost.com from November 10 to December 10 and, in addition to providing developers with the tools and resources to learn how to build on æternity, will facilitate design thinking techniques to ensure that the solutions developed meet real market needs, so that projects can have the opportunity to continue to develop after the hackathon,“ they added.

The hackathon will be supported by blockchain 4 Humanity, an international non-profit organisation: „b4H will lead the design thinking webinars and provide guidance to participants to present meaningful solutions, which will be eligible for USD 16,000 in ae tokens in awards, as well as the possibility of receiving assistance for the further development of their projects“.

Bitcoin and the aggregated crypto market are still battling for significant momentum.

BTC has broken its recent lows, but remains in a somewhat precarious position as price continues to move sideways.

Where BTC goes next will likely depend largely on the stock market, which has had a strong impact on price behavior

Still, Bitcoin’s independent strength remains as most of the on-chain indicators flash bullishly.
An analyst is now finding that the cryptocurrency was able to post an incredibly bullish technical crossover.

He comments that this transition has an 80% success rate, which could mean a serious uptrend is imminent in the short term.

Bitcoin Revolution and the entire crypto market have struggled to gain momentum in the past few days and weeks.

This has largely led both bulls and bears to an impasse as BTC consolidates at around $ 11,400.

Where the coin heads in the near future could largely depend on its reaction to the resistance at around $ 11,600, as continued trading below that level could open the gates for further downside moves.

One analyst, however, comments that Bitcoin has only just been able to see an extremely bullish technical crossover – which seems to indicate that an upward move is imminent.

Bitcoin continues to consolidate – correlation to stocks remains

At the time of writing, Bitcoin is trading at $ 11,450. This is roughly where it has been traded for the past few weeks.

The lack of momentum that BTC has seen lately is due to a period of consolidation within the stock market.

All eyes are now on whether a phase 2 stimulus package will be released in the near future. Investors also wait for the results of the election before rushing into positions.

This indicator shows that Bitcoin is about to take a big boost

One trader comments that Bitcoin has just released a bullish so-called TK-Cross over its cloud. He notes that historically this has resulted in a strong upward move – with 80% confidence.

„Earlier bullish TK crosses with a price above the cloud … You can decide for yourself whether you want to use the 80% hit rate.“

If history rhymes, this pattern suggests that some serious bullish move could be imminent for Bitcoin .

Anonymity is often a subject of controversy in our societies. Some feel that hiding your identity is only for notorious criminals or other shady characters.

In an era of mass state and corporate surveillance where everyone is watched for their actions, it is perhaps difficult to imagine a world where our identity is not constantly sold to the highest bidder.

However, not all have abandoned themselves to this fate, and some continue to fight for their conviction and the protection of their privacy. The famous whistleblower, Edward Snowden , wisely stated in a 2015 interview :

“Saying you don’t care about privacy because you have nothing to hide is no different from saying you don’t care about freedom of expression because you have nothing to hide. say. “

While the battle for the right to anonymity seems lost to some, others are not ready to give up on this quest .

Anonymity through software – the birth of CoinJoin

The right to anonymity is strongly pushed by the majority of the ideologues of bitcoin . This is a sought after property to ensure a censorship resistant form of money .

The inventor of Bitcoin Billionaire scam himself, Satoshi Nakamoto , withdrew completely from the internet without revealing his true identity only 2 years after launching the Bitcoin protocol . This tradition of anonymity appears to carry on beyond Satoshi, as many Bitcoin developers are also anonymous .

Bitcoin mixers

Indeed, some of the most popular software in the Bitcoin universe is mixing software using CoinJoin technology .

First stated in a 2013 Bitcoin Talk discussion by renowned Bitcoin Core developer Gregory Maxwell , CoinJoin technology has come a long way since then.

Like mixers on the darknet that often ended up being scammed because of their centralized form, mixing technologies using CoinJoin are infinitely more secure than their ancestors.

Businesses and individuals who are concerned with the topic of privacy can now anonymize their digital assets without fear with relatively easy to operate software interfaces.

In today’s article, we will explain and compare the different techniques of Bitcoin technology , but first of all, let’s briefly understand what it is.

What is CoinJoin?
The CoinJoin method consists of creating a special transaction including several participants wishing to anonymize their coins. This transaction groups together several “inputs” coming from several sources (several participants) and includes a set of “outputs” with new addresses for the return of coins.

Transaction CoinJoin

The goal is to break the link between the input that pays the output corresponding to it. The new UTXOs thus created will all have the same value so as not to be able to infer the origin of the inputs.

The anonymity comes from the fact that probabilistically speaking, it is virtually impossible to guess from which address the created output originally came.

The more users who join the game, the more difficult it is to infer any analysis according to the heuristics used by famous Blockchain analysis companies, such as Chain Analysis.

There are many implementations of CoinJoin technology and each of them uses it in a different way. Let’s see which one of you is the best fit!

PayJoin, simple and efficient

PayJoin is one of the most minimalist CoinJoin techniques among all those we will present today, because it only takes place between 2 participants . It is a collaborative transaction that relies on making a payment and a transaction simultaneously.

This technique has many advantages, including that of breaking the supposed heuristic that all inputs in a transaction belong to the same party.

Let’s take a look at how a “normal” transaction can be turned into a PayJoin transaction.
