Vitalik Proposes Mixer to Anonymize ‘One-Off’ Ethereum Transactions



“We need a first step toward more privacy,” Vitalik Buterin, founder of the ethereum blockchain network, said Wendesday.

In a new HackMD post, Buterin detailed a design to help obscure ethereum user activity on the blockchain. More specifically, Buterin proposed a “minimal mixer design” aimed at obfuscating user addresses when sending fixed quantities of ether (ETH).

According to Buterin, users can transact in one of two ways. “The default behavior” is to send and receive ether from a single account, which, of course, also means that all of a user’s activity will be publicly linked on the blockchain. Alternatively, users can transact through multiple accounts or addresses. However, this too isn’t a perfect solution to obfuscating user activity on the blockchain.

“The transactions you make to send ETH to those addresses themselves reveal the link between them,” detailed Buterin in his post.

As such, by creating two smart contracts on ethereum – “the mixer and the relayer registry” – users can opt-in to making private transactions on the ethereum blockchain through what is called an anonymity set.

Buterin told CoinDesk in a follow-up email:

“Anonymity set is cryptography speak for ‘set of users that this thing could have come from.’ For example if I sent you 1 ETH and you can’t tell who exactly it was from but you can tell that it came from (myself, Alice, Bob or Charlie), then the anonymity set has size 4. The bigger the anonymity set the more privacy you have.”

Buterin added that the design does not require any changes to ethereum on a protocol level but could be something implemented by a group of users today.

To this point, Eric Conner, product researcher at blockchain startup Gnosis, noted that a key strength of Buterin’s proposal was precisely its ease for integration.

“Strengths are it gives us a solid privacy solution if users want it,” Conner explained. “The goal is to make a solution that can be easily integrated into current wallets.”

At the same time, the design proposed by Buterin does require users to pay a fee – called gas cost – in order to send private transactions. However, for the use cases that Buterin envisions in his mind the fee won’t be a major deterrent for users

Buterin tweeted about the design:

“The main use case I’m thinking of is a one-off send from one account to another account so you can use applications without linking that account to the one that has all your tokens in it. So even though it is a 2m gas cost, it only needs to be paid once per account, not too bad.










Ethereum Takes One More Step Towards Its $200 Target

Will Ethereum Golden Cross and BitPay Support Send ETH Surging?



This week has been all about Ethereum. Finally the second largest crypto asset on the planet appears to be moving without the influence of its big brother dictating things. ETH prices are on the up again today and the fundamentals keep improving.

Ethereum Golden Cross

It has been another good day for Ethereum prices which have finally reached the psychological $200 level after a month trading below it. A dip back to the 50 hour moving average just below $190 yesterday was short lived as price quickly bounced back.

The move back to just below $200 is the highest Ethereum has traded at since this time last month. A slight pullback has dropped ETH to $197 at the time of writing and it needs to break this barrier before its next leg up.


ETH prices 4 hour –

A golden cross is clearly visible on the four hour chart as the faster 50 MA crosses above the slower moving 200. This is a bullish trend reversal signal and is usually followed by a rally. However, one analyst has noted that total market capitalization has not increased indicating that no new money is flowing into ETH yet.

“ETH is up but total crypto market cap still staying flat, price increase could just be money being moved around from other crypto’s rather than fresh money. Waiting for TMC to pass $260B”

Others are hoping that Ethereum can kick start a wider altcoin run as Bitcoin appears to be running short of buyers. At the moment the rest of the altcoins are flat or in the red but the possibility of an ETH decoupling will be strengthened if it can break the $200 barrier.

BitPay Adds Support

News that crypto payments provider, BitPay has finally added Ethereum support is also bullish. In a press release the company said businesses can accept Ethereum for purchases without the need for any integration or enhancements. Originally only BTC, BCH and a few stablecoins were available on the platform.

Ethereum godfather Vitalik Buterin was pleased with the announcement, adding.

“It is exciting to see BitPay leading the way in integrating Ethereum into global payment systems. This truly opens up a new world of possibilities for the Ethereum ecosystem, and together we can continue to be a leading innovator for real world use cases for cryptocurrencies.”

The news adds to other bullish fundamentals for Ethereum such as Santander’s $20 million bond on the blockchain last week, further developments in the DeFi ecosystem for DAI, and a successful network test of ETH 2.0 clients.

Ethereum Price Analysis: ETH Upsurge Could Extend Above $200



  • Ethereum price started a strong upward move and broke the $185 resistance against the US Dollar.
  • ETH price is trading near the $200 level and it might continue to rise in the near term.
  • There was a break above a crucial bearish trend line with resistance near $175 on the 4-hours chart (data feed from Coinbase).
  • The price is showing positive signs and it could even break the $200 and $202 resistance levels.

Ethereum price is trading with a positive bias above $190 against the US Dollar. ETH price might correct lower, but dips are likely to remain supported near $190 and $185.

Ethereum Price Analysis

This past week, we saw positive signs for Ethereum price above the $175 support against the US Dollar. The ETH/USD pair followed a bullish path above the $180 level and the 55 simple moving average (4-hours). As a result, there was an upside break above the $182 and $185 resistance levels. On the other hand, bitcoin price struggled to gain traction above the $10,400 and $10,500 resistance levels.

During the recent rise, there was a break above a crucial bearish trend line with resistance near $175 on the 4-hours chart. The pair traded close to $200 and it is currently consolidating gains. An immediate support is near the $194 level, plus the 23.6% Fib retracement level of the recent upward wave from the $174 low to $200 high. If there is a major downside correction, the $186 and $185 levels might provide support.

Moreover, the 50% Fib retracement level of the recent upward wave from the $174 low to $200 high is near the $186 level to provide support. Therefore, dips towards the $186 and $185 levels are likely to find a strong buying interest. Below $185, the price might start a fresh bearish wave and it could revisit the $175 support area.

On the upside, there are two important resistances near $200 and $202. If there is an upside break above $200 and $202, the price could rally significantly above the $205 level. The next major resistance is near the $225 level.
