Ethereum Hard Fork to Commence on August 5

ETH's first block was mined on July 30, 2015 - now, cryptocurrency is six years old.

On August 5, Ethereum will go through the London hard fork. Ethereum 2.0 will be an upgrade to Ethereum on several levels: changing PoW for PoS will result in increased transaction capacity and smaller fees. Overall, the network will become more sustainable.

On its FAQ page, Ethereum developers are warning ETH holders not to fall for scams that may insist to somehow prepare for the merge. Be careful: you don't need to do anything. However, the merge and shard chain upgrade may impact dApp developers, but the specifications have not been finalized yet.

Monero Bug Can Affect Privacy

On July 27, the Monero team posted a thread on Twitter, saying that they spotted a significant bug in XMR's decoy selection algorithm that may impact transactions' privacy. In short, if a user spends funds immediately after receiving them (about 20 minutes), there's a good chance of action being identified as the true spend. This bug in no way increases the risks of one's funds being stolen or transactions info revealed.

Monero developers recommend waiting at least one hour before spending newly-received XMR funds until a fix is deployed.

Bitcoin Mining Difficulty Rise

According to, Bitcoin's mining difficulty is now 14.50T, which is 6.03% higher than the previous rate. For the first time since May, difficulty rose. In July, the rate started to recover amidst Chinese miners moving out of their provinces and finding new jurisdictions to operate.

Even though mining difficulty increased, it's still 54% easier to mine bitcoin than it was in mid-May.
