The Shanghai launch of the new etheurum network last April marks a great turning point in the field of crypto-currencies. This update changes staking and constitutes an unprecedented event in the evolution of the blockchain both in terms of its efficiency and its profitability. It is therefore the shifting validation of ethereum transactions from proof of work to proof of stake. The first advantage was not long in coming. This passage will allow reduce electricity consumption by more than 99% across the network. In at the same time, this development will give advantages of gaining speed in the transactions. In this series we relate the event as soon as the date of the April 12 at the highly anticipated after launch. The rise in the price of ether was not long in coming. As soon as the update is announced Shanghai Capella, prices immediately shot up. For the first time since seven months Ether hit the 1900 USD mark. Cryptocurrency takes advantage of the investor confidence. It is now trading at 1911 USD. The more we nears the announcement date, investors get excited and the price goes up. These the latter expect very significant changes. This update of the Ethereum network will make crucial improvements to the platform. First those who own ethers will have the possibility to withdraw the funds deposited in staking, which gives great flexibility to validators and liquidity depositors. A second improvement concerns the security of transactions. This shift to proof-of-stake provides greater security and more efficient operation of the Ethereum network. And all of this comes with a significant reduction in energy consumption. The third improvement concerns increasing the capacity to process more transactions. The transactions therefore will be done even more quickly than they were before this passage. Despite some hesitation on the part of some investors, it is quite clear that-thanks the definitive move to the proof-of-stake consensus mechanism and the possibility holders of ethers to withdraw their funds in staking- Ethereum hits hard. He is positioned as a key player in the ecosystem of crypto- currencies and imposes its desire to be an undisputed and ethical alternative to the bitcoins. On the other hand, some investors remain skeptical of this update. With only $2.5 million entry into crypto investment products, some investors are right to be concerned since the volumes recorded show a decrease of 33% compared to the previous week. The reaction of bitcoin was also more favorable as it made an inflow of 8.8 million of dollars. For investors who own ethers, this development allows them to provide opportunities: it becomes easier to make staking investments, and to receive income from the validation of transactions. For the timeline of this story, this opportunity starts in 2020 on the network ethereum. When staking was developed during the testing phase on the network ethereum designated as 2.0, it was then possible to make income around plus 10% annually. Ethers that are in staking today, before the update, are at 14%. This ethereum 2.0 network system has often discouraged investors because staking necessarily had to send in ethers in a specific smart contact but without any facility to leave its position. All of these issues are going to be fixed with this Ethereum protocol update. named Shanghai. Ethereum engineers clarified that the feature main feature of this update will be its ability to exit a position of staking stuck on the protocol. And from there, it will be possible to draw one income. Everyone undoubtedly thinks that Ethereum will be an attractive asset for investors, because it is obvious that investors will be able to benefit from this mechanism. Many have already bet that several if not all trading platforms will put set up opportunities for ether holders to stake automatically. Staking is therefore a validation process undertaken by many blockchain protocols. The process is as follows: to validate a transaction on a blockchain and adding a block, it is necessary to solve a problem cryptographic. And the cryptographic solution is done as soon as the ethers are stored on trading platforms.
