“Random Genius” implemented Buterin’s idea of a mixing service for Ethereum

In an attempt to tackle the lack of privacy Ethereum, developer Kendrick Tan developed a mixing service for the second most capitalized cryptocurrency.

The basis of its development called Heiswap formed the basic specifications for such a service, described by Vitalik Buterin in May of this year. The mixer itself is available on the Ropsten test network at heiswap.exchange , and as the founder of Ethereum already noted, this is a “cool project” created by an “accidental genius” that he has never heard of before.

Presenting his project, Kendrick Tan wrote:

“Heiswap is an Ethereum mixer that allows users to“ launder ”ETH confidentially (that is, it hides the recipient of money)”

Currently, participants in transactions in the Ethereum network can be traced by simply analyzing the blockchain. The created service works as follows: users send a fixed amount of coins to the Heiswap smart contract, and when the number of users required to participate in the mixing round is collected, the tokens are mixed.

After that, users can withdraw their coins, while the details of the recipients are hidden, thereby providing the necessary anonymity.

It is worth noting that at least five users are required to participate in a mixing round, but to increase anonymity, the sender has the option to increase their number.

Recall that in February, researchers at Stanford University and Visa Research presented a privacy mechanism for smart contracts at Ethereum. The solution is called Zether and is a new smart contract that can be executed individually or through other smart contracts. Zether saves the data on account balances in encrypted form and makes it possible to deposit, transfer or withdraw funds through cryptographic evidence.

G7: stablecoins pose a threat to the financial system

Published

on

A recent report from G7 suggests that global stablecoins can be dangerous to the stability of the financial system.

The report describes many of the risks that are associated with the use of digital currencies. It even explains that even if the companies involved in Libra could manage to solve some minor regulatory problems, they would not be able to get permission from the main regulators. The document also notes that G7 believes that no stablecoin project should have the right to start its activities until certain problems with the supervision and management of the crypto industry are resolved, all risks are eliminated.

G7 also thinks that stablecoins that have the ability to scale quickly can suppress the development of competitors and threaten financial stability, as there is a risk that users may one day be disappointed in this coin. It is anticipated that the provisions of this document will be discussed by finance ministers at the IMF's annual meeting, scheduled for this week.

Such statements explain the hostility of world regulators to Libra and TON projects. For example, Gabor Gurbaks, a digital assets strategist at VanEck, said on his Twitter blog the day before that companies, such as Visa, Mastercard, eBay, Stripe, received letters from regulators asking them not to experiment with Libra before leaving Libra. a new project, otherwise they would have additional, undesirable obligations to regulators.

The growing complexity of Bitcoin mining in 2019, how is it determined and what depends on it?

Published

on

This year, the price of Bitcoin (BTC) ranged from a minimum of just over $ 3,000 to a maximum of about $ 13,000. At the same time, the complexity of BTC mining , which measures the complexity of the calculations needed to mine new coins and create new network blocks, has been growing unprecedented.

Bitcoin mining difficulty is adjusted approximately every two weeks to take into account the hashrate of new miners on the network. Despite the fact that the general trend has been upward almost since the creation of the network, short but significant failures happen. For example, in December 2018, mining complexity decreased three times in a row, the total drop was almost 30%.

In this calendar year, the difficulty of mining BTC decreased five times, but no more than 1.18%. This is unprecedented. In no previous year, the most serious drop was so low. In the entire history, at least one drop was more than 5%.

Of course, 2019 has not yet ended, but it is worth noting that at that time last year, the difficulty of mining BTC decreased only once (3.45%, which is more significant than any decrease in 2019).

If this trend continues, it will confirm that the BTC miner community is less sensitive to currency price fluctuations than ever before.

To understand why, it is worth considering the basics of the complexity of cryptocurrency mining . The Bitcoin network produces 2016 new blocks every two weeks. Maintaining this speed is important for network operation. Blocks are generated by miner computing systems that solve mathematical problems. In this case, it is appropriate to compare the miners with the players in the lottery, and the difficulty of mining is with a very low chance of each individual player to win. Each time someone “wins” the lottery, a block is created.

Since bitcoin networks need blocks that are generated at a predictable speed, the complexity of this “lottery” should vary depending on the number of “players” (miners). For example, if many miners leave the network, the mining complexity should be reduced, or the rest will not have enough power needed to generate new blocks at the speed required to maintain the network.

In fact, the Bitcoin mining system is more complicated than described above, however, according to its basic principle, the upward movement of Bitcoin this year is a bullish sign. Investors come and go, the price fluctuates up and down, but interest in Bitcoin mining is clearly growing, and this year it has become more stable than ever before.

Europol: Bitcoin remains the most popular cryptocurrency among cybercriminals

Bitcoin is still the preferred cryptocurrency for cybercriminals, Europol stated in the annual report “Assessing the threats of organized crime on the Internet” (IOCTA 2019). “Although we previously reported a slight shift towards more private cryptocurrencies such as Monero, bitcoin is still the currency of choice for both legal and criminal use,” the organization said.

Bitcoin is still the preferred cryptocurrency for cybercriminals, Europol stated in the annual report “Assessing the threats of organized crime on the Internet” (IOCTA 2019).

“Although we previously reported a slight shift towards more private cryptocurrencies such as Monero, bitcoin is still the currency of choice for both legal and criminal use,” the organization said.

In previous IOCTA reports, the organization pointed to the growing popularity of altcoins such as Zcash, Monero, and Ethereum among cybercriminals.

This year, Monero was the only altcoin mentioned by the EU police organization in a report. It notes that the use of the coin mainly relates to darknet markets that accept or trade Monero.

Europol emphasized that Monero was widely used for hidden mining, the distribution of which has been declining throughout the current year. The latter is partially due to the termination of the Coinhive browser mining service in March, the organization said.

Recall, it was previously reported that the volume of bitcoin transactions in the darknet for 2019 may exceed $ 1 billion.
