Bitcoin – The Safest Blockchain Platform

     Safety is paramount for all blockchain platforms, according to Satoshi Nakamoto, in Bitcoin’s white paper,

“The system is safe as long as honest nodes collectively control more processing power than any group of cooperating attackers.”

Bitcoin, having the highest processing power, increases the improbability of external or internal attacks, is emerging as the “safest Blockchain ecosystem”.

The only way to control this system in a malicious way would be for the attackers to control
the majority of the processing power on the blockchain. Recently, Bitcoin Gold, Verge
and ZenCash, were attacked by malicious miners, taking control of their networks and
forcing other miners to double the cost by imposing a blockchain that has been mined to
propagate, and created a bifurcation that invalidates previous transactions.

Bitcoin, the original and longest running blockchain, has not been attacked in any way,
despite being exposed to attacks on many different occasions. An attack on Bitcoin is literally impossible since it will take about $2.3 billion in electricity and mining equipment for an attack to have anny success. Bitcoin appears to be the safest blockchain against internal or external attacks and will remain in charge of protecting history and its legitimacy as a technology.

Bitcoin Gold Platform Update

     Thanks to the recent increase in attacks that were carried out on the Bitcoin Gold network, as well as the appearance of an ASIC (Integrated circuit for specific applications) mining equipment, the team of developers of this blockchain has opted to change the mining algorithm that uses this network.

Currently they use the Equihash algorithm, which is shared with other currencies such
as Zcash, ZenCash, Komodo, Bitcoin Private, and many others. One of their main
characteristics is that it was resistant to ASICs, which helps keep mining decentralized,
the fundamental pillar of Bitcoin Gold.

The team has worked hard, in recent days, to develop this new code and in order to be able to execute it as soon as possible in the test network, before sending it to the different
sectors of the ecosystem so they can update it.

“We want this update to be ready and implemented this month, but it will not do
the network any good if we update before the wallets, the mining pools, the
exchange houses and others are ready”

This measure is not the definitive solution. The implementation is due to the recent
attacks, but the developers of BTG know they need to work to keep Bitcoin Gold
decentralized.

“This will significantly reduce the risk that ASICs put into our network. This solves our short-term security problem and gives us time to consider other LONG-TERM alternatives […] Although we know that this parameter change is not A permanent solution – this change will not stop the ASICs forever- we know that it will solve our problem for now.”

2nd Atomic Swap Between Bitcoin & Litecoin

     The Lightning Network has registered the second live reproduction of an atomic swap between the Bitcoin and Litecoin blockchains.

The reproduction was made by the developer Daniel McNally in conjunction with the Exchange Union team, who uploaded the demonstration to YouTube and communicated on their social networks how an instant cryptocurrency exchange was made between Bitcoin and Litecoin, executing Atomic Technology Swaps on two Lightning Network nodes.

Atomic Swaps, also known as atomic exchanges or the exchange of crossed chains, are a specialized technology that allows exchanges between cryptocurrencies in different blockchains without the need for the intermediation of a third person as a house of exchange.

The statement confirmed that the exchange action needed a lot of development work, and even some hacking, to work effectively. However, it was also confirmed that commercial exchanges will be made in a much simpler way.

The Exchange Union group ensures that this type of atomic exchanges will preserve the privacy of user transactions since they leave no trace of the transaction. They also assured that it is an infallible technology with very low commissions, which are the most beneficial characteristics of the Atomic Swaps. The latest test is also considered a confirmation that Atomic Changes are a sustainable technology over time and that in the future they will have an important function in blockchain.

“It is tangible proof that the underlying technologies that drive Exchange Union (atomical interchanges between chains in the payment channels) work in practice,”

a recently issued statement exclaimed. This last reproduction turns out to be the second atomic exchange carried out between the Bitcoin and Litecoin networks, the first one was held in November 2017 and marked a milestone in the history of transfers between both networks. In addition, the Atomic Swaps have also shown their capabilities by making exchanges between Bitcoin and Ethereum, as well as between Zcash and Ethereum.

The project has also managed to guide the Litecoin and Monero networks to carry out atomic exchanges in the near future. In follow-up of future projects, the Exchange Union organization plans in the coming months to prepare to continue producing exchanges, merge with Lightning Network and carry out a group of tests in its XUD node.

Together with the Lightning Network – software dedicated to creating parallel payment channels in blockchain- and SegWit, the Atomic Swaps become another solution for the scalability of the blockchain, providing users with economic and instant transfers that could help to decongest the networks and increase adoption of cryptocurrencies.

Crypto Valley Will Assist Swiss City With Blockchain Based Vote

     Switzerland has been referred to several times as the most blockchain-friendly country in Europe. Due, in part, to the existence of “Crypto Valley” and the country’s tax-free policy for crypto investors. As reported by local news outlet swissinfo.ch, The city of Zug will allow it’s 29,804 inhabitants to take part in a blockchain-based test vote. The small scale, consultative vote will utilize the blockchain-based, eID system, which was set up in November of last year and currently claims around 200 users. Voters will be able to vote via their smartphones by downloading the existing uPort app to register. This will be Switzerland’s first municipal vote using blockchain, and is scheduled to take place between June 25th and July 1st of this year.

According to the report, the city of Zug is already home to several blockchain start-ups. The city also accepts payment for few services in cryptocurrencies. Voters will be surveyed on whether they are in favor of fireworks at the annual Lakeside Festival, and whether they think digital IDs should be used to borrow books from the library or pay parking fees. Voters will also decide if blockchain-based eID system should be used for referendum votes in the future. Since the upcoming vote is a trial, its results will be non-binding for city authorities.

Having established “Crypto Valley”, a global hub for crypto and blockchain development, Zug has become one of the centers for the

“world’s leading ecosystems for crypto, blockchain, and distributed ledger technologies.”

Russia Will Not Issue Cryptocurrency – Vladimir Putin

     With the constant discussion of nations and central banks issuing their own cryptocurrencies, Russian President, Vladimir Putin recently dissipated any rumor by clarifying that,

“digital currencies are a phenomenon that is just developing”

Putin added that,

“Russia can not have their own cryptocurrency, just as no other territory should have it, because when we speak of digital currencies, this is because it is an
issue that goes beyond the borders of the nation and not inherent in our
jurisdiction. […] The Central Bank believes that cryptocurrencies can not be means of payment and liquidation, can not be a means of accumulation and are not guaranteed by anything. That is why our approach must be cautious during this period. “

Although not entirely wrong, considering the measures that are evaluated, and which
will be imposed by international bodies, such as the European Union, for example.  However, the comments contradict all of the announcements that took place in October
2017 and January 2018, in which Putin himself, ordered that the Ministry of Finance to
establish measures for the launch, exchange, investments and storage of cryptocurrencies in the Russian territory.

In spite of everything, there is no doubt that, although there is some uncertainty and
opinions that contradict, for the authorities in Russia, cryptocurrencies are a “phenomenon” that could contribute to the development and growth of different sectors of the country in the future.

Government Cryptocurrencies Could Save EU Billions

     According to the Deputy of the Bank of Italy: government cryptocurrencies could save the EU up to € 76 billion.

Fabio Panetta, Deputy Director of the Bank of Italy, gave an opening speech
focused on the digital currencies of the central bank (CBDC) at the conference of
the SUERF / BAFFI CAREFIN Center in Milan on Thursday, June 7th.

Unlike traditional cryptocurrencies, “a liability that does not belong to anyone,” the deputy
governor emphasized from the beginning that a CBDC would be a central bank liability, backed by its assets. By first addressing CBDCs as a possible means of payment, Panetta considered their advantages as “at best, unclear” compared to the existing digital payment
mechanisms offered by the private sector.

Where Panetta saw a key potential justification for the issuance of the CBDC, was to reduce costs in production, transportation and cash disposal. He cited estimates that these costs amount to about half a percentage point of GDP in the EU annually, around € 76 billion, a figure equivalent to almost half of the EU’s annual budget.

Panetta added that if combined with distributed ledger technology (DLT), the potential cost efficiency gains of a CBDC could be even more significant. Considering the potential use of CBDCs as a store of value, Panetta noted that in addition to virtually zero storage costs, a CBDC could function as an asset with “unique characteristics”, without credit and liquidity risks. As such, it could be preferred to other means of wealth storage, including bank deposits.

Panetta clarified concerns that a change in bank deposits to a CBDC wouldn’t necessarily threaten the financial system as a whole. Although it could squeeze the return on the net interest margin (NIM) that supports the credit models of the banks.

Instead, Panetta stressed that CBDCs could innovate existing operational frameworks and push the market towards a “narrow banking model” that would need to be considered again. Panetta significantly increased traceability and privacy – “probably the most important issue” – related to CBDC, as a “political” issue for society as a whole, beyond the exclusive domain of central banks.

Last month, the Bank of England issued two staff working documents dedicated to the issue of CBDCs. The first presented several risk analyzes for CBDCs, and found that there was no reason to believe that the introduction of a CBDC would have adverse effects on private credit or the total provision of liquidity to the economy.

The second document suggested, like Panetta, that the adoption of CBDCs could pose a threat of competition for commercial banks, echoing a March report from the Bank for International Settlements (BIS) that also suggests that “in times of financial stress”, national investors are likely to consider the attractiveness of CBDCs in relation to bank deposits, with many possible side effects for financial stability.
