This Bitcoin developer is using “swaps” to solve BTC’s long-running “pseudonymous” privacy issue

Avatar

Published

Bitcoin’s privacy features have been under fire by critics since early 2013. 

While the protocol remains technically robust and mathematically secure, a loophole allows blockchain analysts and cryptographers to link transactional behavior with users, leading to some term Bitcoin as “pseudonymous.”

But one veteran developer believes the problem can be solved using a framework built-in 2013, a then-launched protocol called CoinSwap invented by Blockstream’s Greg Maxwell. 

Improving Bitcoin privacy 

Chris Belcher, an independent developer whose Github’s history shows hundreds of commits across various Bitcoin-centric applications, released his new implementation proposal for CoinSwap last week. 

Belcher’s approach builds on CoinSwap’s earlier solution — that of utilizing a “swap” method to conduct transactions. At the time, the framework relied on conducting transactions via an intermediate wallet instead of a direct transfer, causing wallet addresses to be “masked,” effectively. 

But the protocol proved to be difficult to implement and never came to fruition, notes Belcher. A relevant Bitcointalk thread has not shown activity since 2016, meaning the project was, indeed, left abandoned. 

However, the Bitcoin developer noted CoinSwap holds “great promise,” and is the “next step for on-chain bitcoin privacy.” 

Belcher, in his implementation, proposes creating a “liquidity market” similar to JoinMarket and CoinJoin. He explains:

“We can get slightly bigger anonymity set by using 2-of-3 multi-sig with a fake third public key. For a much greater anonymity set, we can use 2-party ECDSA to create 2-of-2 multi-signature addresses that look the same as regular single-signature addresses[2].”

The working

Belcher uses a multi-party mechanism for avoiding two-party transactions, such that Bitcoins moved from a user’s wallet will be “routed” through several other user wallets before reaching the recipient. All intermediaries will act as “market makers,” only knowing what the previous and the next Bitcoin address is. 

The above approach helps boost the fungibility of Bitcoin, making it a “better form of money” in Belcher’s view. He notes the implementation could also be used as a “Bitcoin mixing app,” but wallet providers could also implement the system and increase privacy for their users. 

It must be noted the approach is highly technical and more complex than the above explanations seem, presenting several issues along the way to overcome to ensure its significance. 

Some issues include malicious users “blocking” a user’s transactions “indefinitely” on the CoinSwap protocol. “Fidelity bonds” can help solve this particular issue, with Belcher explaining this in-depth on earlier Github posts.  

Meanwhile; Belcher noted the approach may look similar to the Lightning network but features several improvements over the latter. One is presenting better liquidity for users, with Belcher stating “it’s hard to imagine the Lightning Network will ever reliably” route a 200 Bitcoin transfer to any node in the Bitcoin protocol.

Breaking: Leading US Exchange Coinbase Prepares For a Stock Market Listing

The leading US-based cryptocurrency exchange and one of the biggest companies in the industry, Coinbase, reportedly prepares for an official stock market listing.

Coinbase Prepares for Stock Market Listing

According to a report filed by Reuters minutes ago, the leading US-based cryptocurrency exchange, Coinbase, has started making preparations for a stock market listing.

Should the procedure be a success, Coinbase will become the very first major US cryptocurrency exchange to go public and it could happen as early as this year.

However, the listing would need the approval of the US Securities and Exchange Commission (SEC). Needless to say, if the watchdog greenlights it, this would be a serious victory for the cryptocurrency community and a major regulatory endorsement.

Sources familiar with the matter told Reuters that the company is actually exploring its options to go public through a direct listing instead of the traditional Initial Public Offering (IPO).

Coinbase’s Institutional Focus

Receiving the green light from the US SEC and going through with an official stock market listing would certainly send a strong signal to institutional investors who are looking for exposure to cryptocurrencies.

This seems to have been the focus of Coinbase of late. Earlier in May, CryptoPotato reported that the exchange acquired a leading cryptocurrency brokerage Tagomi. This was done to enhance the company’s proposition for advanced and for the “most sophisticated crypto investors.”

Back then, the official announcement stated:

“The addition of Tagomi will round out our product suite for the fast-growing institutional trading market. It will allow us to offer custody, professional trading features, and prime brokerage services on one platform, giving sophisticated investors the seamless, powerful trading experience they have come to expect in equities and FX markets.”

Moreover, Coinbase became one of the first clients from the crypto field of the US banking giant JP Morgan.

Uncovering the Reason Behind Female Crypto Influencers’ Instagram Bans

Avatar

Published

on

Female crypto influencers that have spoken up about gender inequality in the blockchain space have recently had their Instagram accounts removed. Cointelegraph previously reported that three female crypto influencers — Rachel Siegel, Lea Thompson and Catalina Castro Lagos — were mysteriously removed from Instagram following Siegel’s comments on Twitter about the underrepresentation of women in the crypto community.

The remarks from Siegel were made in response to Binance only including one woman (herself) as a nominee for their global influencer awards. Lagos was one of only two women to be in contention for the award for the Latin America region.

Siegel, better known as CryptoFinally on social media, told Cointelegraph that backlash from the crypto community began in June of this year following a video she posted on Twitter regarding gender disparity. “I received an extreme amount of backlash from the crypto community for making this video. People started viewing me as an angry feminist,” she said.

After posting her video on women being underrepresented and even harassed in the crypto community, Siegel began to livestream regularly with Thompson (GirlGoneCrypto) and Lagos (TechWithCatalina) to discuss cryptocurrency and blockchain developments. Siegel explained that backlash from the crypto community eventually settled down when she began to focus strictly on the news.

However, numerous negative remarks were made following her video regarding Binance’s decision to nominate just one woman for its global influencer awards and only two women for their Latin America influencer awards. Siegel said:

“There are many women in the crypto space with influence, so when I heard these numbers I pointed out the gender discrepancy. We are looking at a global scale of women in crypto and saying that out of the entire world, 25 people were selected and I was the only woman with enough merit to make it on the global list. This points to a much larger problem we have in this space when it comes to representing women.”

Binance co-founder, Yi He, told Cointelegraph that there were actually a total of 18 women nominated for the Binance influencer awards. However, Siegel was nominated for the Binance influencer award by a community vote, along with other regional influencers like Kaká Furlan and Carol Souza — hosts of the UseCripto YouTube channel — as well as Dovey Wan and Anthruine Xiang. As Yi He said:

“The influencer nomination and selection process are fully driven by the community, not both the community and Binance team as it was originally reported by Cointelegraph. Additionally, the community-nominated and community-voted influencer awards have limited slots. For example, Miss Bitcoin (Mai) is an important part of the crypto community who has led impactful philanthropy efforts in Japan; there are many great influencers and women leaders in our space who may not have been represented for awards that are limited in categories.”

Yi He further noted that Binance respects the point Siegel made on Twitter, noting that Binance will ensure more diverse nominees and influencers while balancing their community-driven votes.

Is the crypto community to blame?

While Binance’s influencer awards are purely community-driven, this could further highlight Siegel’s thesis that gender discrimination is very much present within the crypto community. Siegel explained that she does not blame Binance in any way for the nomination process, noting that community voice in the blockchain space is extremely important.

However, Siegel did note that the crypto community has exhibited inappropriate behavior toward women over time, a point that could be connected with the recent Instagram ban of Siegel and three other female influencers.

Shortly after posting her video on Twitter regarding the Binance influencer awards, Siegel’s Instagram account was banned. Oddly enough, Thompson’s and Lago’s Instagram accounts were also removed that same day, on July 6.

Yet according to Siegel, this wasn’t just a coincidence. She thinks someone or a group of people reported all three women’s accounts to Instagram in hopes that they would be taken down, as Siegel explained:

“I think that someone in the crypto community mass reported all three of us. Instagram has a very bad backend for when it comes to these reports, meaning that if enough reports are made, they will automatically ban users. Instagram would be the easiest place to perform an attack like this, instead of on Twitter for instance.”

Siegel also explained that comments have been made across social media platforms that show users making negative and sexually harassing remarks towards women in the crypto space. For example, on the bulletin board website 4chan, there is an inappropriate comment posted underneath a photo taken of Siegel alongside Ethereum co-founder, Vitalik Buterin.

Siegel further noted, “There has been quite a few comments on my recent tweet from people saying they want to get female influencers like us banned from social media.”

Interestingly, another woman influencer in the crypto space, who recently did a live stream with Siegel, Thompson and Lagos, also had her Instagram account taken down on July 6. CEO of the Bitcoin Center in Miami, Eryka Gemma, told Cointelegraph that Instagram won’t let her log into her account anymore. Gemma originally received a message from Instagram saying that her profile had been disabled for violating community terms.

On July 7, Gemma received another message from Instagram saying that her account had been disabled for “pretending to be someone else.” This is strange considering I did a livestream with Siegel, Thompson and Lagos the week prior,” Gemma remarked. Meanwhile, a now-deleted account stated that the 4chan community was responsible for inciting the bans:

Siegel, Thompson and Lagos’ accounts were also removed for impersonation. Due to the fact that all four women had their Instagram accounts removed on the same day for the same reason gives Siegel and the other women reason to believe that members from the crypto community organized an attack in response to recent remarks on gender discrimation. At the time of publication, all four women’s Instagram accounts are still down. Siegel commented:

“This is less about losing our accounts and more about the notion that this is an unfair attempt at silencing women in blockchain. Additionally, it’s not about influencers being deserving of respect, but about human decency in our industry. Absolutely nobody deserves to be harassed and attacked to the extent of which I’ve seen online in our community.”

Ensuring women have a seat at the table

A recent report from CoinMarketCap revealed the number of women in the crypto space increased by 43.24% during the first quarter of 2020. In addition, a study conducted last December by Grayscale found that 43% of investors interested in Bitcoin are women, up by 13% compared to 2018.

While it is uplifting to see new statistics showing an increase of women in the crypto and blockchain space, the community must be inviting toward women to ensure this number grows. Yi He from Binance explained that hiring female executives is one way to make sure that women’s involvement grows, noting that women make up about 40% of the workforce at Binance, many of which are executives like her.

In addition, the enterprise blockchain space also appears to be attracting more women. A recent diversity survey conducted by Hyperledger found that 13% of survey respondents were women. In 2017, only 5% of women participated in the same survey.

Senior technology architect at Accenture, Tracy Kuhrt, gave a lecture at Hyperledger Global Forum 2020 entitled, “Letting Go of Your Unconscious Bias,” with diversity and inclusion being major talking points. Kuhrt told Cointelegraph that the enterprise blockchain space in particular is vested in diversity:

“We all have a part to play, big or small, in increasing the diversity within the enterprise blockchain space. It could be something as simple as making someone feel welcome and encouraging them to participate, to mentoring and acting as a role model. It’s difficult to be what we can’t see, and for that reason we must prioritize expanding who is in the blockchain community.”

As for Siegel, who has been involved in the crypto community for a few years now, she expressed excitement for the direction in which the space is heading. “I believe in standing tall for diversity and inclusion, and having these conversations is important. I’m glad that we’re doing it,” she said.

Bitcoin’s hodling metrics: Don’t trust what you see

Avatar

Published

Many people kicked off 2020 with a lot of optimism, especially community members of the world’s largest cryptocurrency – Bitcoin. However not all things have gone according to plan. With most economies reeling from the effect of the global pandemic and a liquidity crisis pushing BTC’s price below $4k a few months in, Bitcoin price action was evidently affected.

Despite everything, many investors continue to hold a significant number of Bitcoin. With the number of whale accounts hodling Bitcoin increasing, the question arises –  is an upcoming bull run inevitable for Bitcoin?

According to Glassnode CTO Rafael Schultze-Kraft, investor confidence is strong within Bitcoin. During a recent interaction, he noted how there is a need to look at Bitcoin at a microscopic level in order to understand how much BTC is being moved around and whether or not the metric has predictive power over the coin’s future price.

Looking at Bitcoin’s addresses and the amount of Bitcoin they own and hodl is unlikely to paint an accurate picture, he said.

“How many are actually Hodling? This is a question that has been very difficult to answer because the approximation has been until now was to look at addresses. The problem with that is that you can control more than one address. And there’s also addresses that hold funds of multiple users.”

Source: Glassnode

Interestingly, the hodling sentiment within the Bitcoin ecosystem continues to be fairly strong, despite the price being stuck below the $9,500 level. However, according to market data provided by Skew, the past few months have seen a significant dip in Bitcoin’s realized volatility, dropping to 83.6 percent along with a steady rise in new active addresses that hold non zero balances.

A few months since the price crash on 12 March and the third block reward halving, the improving metrics might indicate that Bitcoin may see better days in the coming months.

However, Schultze-Kraft highlighted that looking at entities and not addresses within Bitcoin can also shed light on the coin’s volume. This can also provide a clearer understanding of what the present hodling sentiment implies and whether the king coin is rife to finally break out into the five-figure spectrum. He argued,

“Up to 75% of all the volume being moved on-chain does not really change hands though. and that it is all internally within the entities”
