The Bitcoin Core development team has been busy.

During the weekend, the team announced the release of a new Bitcoin Core version0.19.0.1 – that brings several new improvements & tweaks to the (blockchain) table.

Probably the most important one has to do with Bitcoin Core’s compatibility on systems with limited memory. The team adjusted some of the parameters to reduce memory usage and make the software more friendly for the low-end systems like a Raspberry Pi or a low-cost VPS.

Moreover, the new release further enhances the avoid_reuse privacy feature – that flags and blacklists hacking attempts to steal funds from the Bitcoin Core wallet – and introduces the bech32 SegWit-friendly addresses by default to the GUI release.

Yet Another Class Action Lawsuit Against Tether

Over the last couple of months, Tether – the company behind the most popular & used stablecoin in the cryptocurrency market USDT – has been under constant fire. A couple of new class-action lawsuits have been filed against Tether & cryptocurrency exchange Bitfinex accusing them of market manipulation.

The latest class lawsuit was filed on Friday, November 22, 2019, in Washington State. A similar lawsuit was filed on October 6, in New York.

As always, Tether dismissed the price manipulation & market rigging accusations heartily claiming they are based on ‘bogus reasearch’ & are just attempts by ‘mercenary lawyers’ who try ‘to use Tether to obtain a payday.’

The company behind USDT made it clear it will not look for a settlement of any kind and will proceed to legally retaliate once the lawsuits ‘are ultimately disposed of in due course.’

Hard Problems In Cryptocurrency Reloaded

Ethereum co-founder Vitalik Buterin took a hard look back in the past by revisiting his own post written five years ago simply titled ‘Problems.’

On Friday, Buterin shared his 2019-ready ‘updated’ thoughts on the ‘Problems noticed’ in 2014.

Not much has changed since 2014 concerning the ‘hard problems’ most cryptocurrencies are currently facing. For example, while there have been many theoretical breakthroughs on the scalability matter, the practical side is still lacking as Buterin notices in his latest blog posts. The same goes for the Proof of Stake and Proof of Storage topics.

Nevertheless, there are a few topics that have been solved since then, according to the Ethereum co-founder. The ‘Arbitrary Proof of Computation’ is now a forgotten problem thanks to the implementation of SNARKs.

What are the new ‘hard problems’ the cryptocurrency market is facing in 2019? Post-quantum cryptography, oracles, improving the current primitive decentralized governance mechanisms, and obviously putting all those interesting theories (Ethereum’s own Proof of Stake included) into practice.


Are Buterin’s ‘hard problems’ in 2019 solvable? Will Tether succeed and prove the company didn’t rig the markets in 2017 – 2018 & forward? Tell us your opinion in the comment section below.
