First of all, it introduces Proof-of-Stake consensus: validators that stake ETH will replace GPU miners in creating blocks and ensuring the network security.
Eth2 also introduces sharding that will increase the cryptocurrency blockchain bandwidth 64 times. It means that it will be able to handle at least 64x more transactions per second and even more going forward. The initial phase of transition to Eth2 known as Phase 0 started on December 1, That was when Ethereum launched its new network called Beacon Chain that activated the Proof-of-Stake mechanism.
After the merge of the current network Ethereum 1. How much less profitable is staking compared to mining? To answer this question, we found out their profitability and compared them. We also talk about positive and negative aspects of Proof-of-Work and Proof-of-Stake.
It also contains guidelines for validators willing to help to secure the blockchain and earn rewards. At the current amount of coins at stake, the annual percentage rate is 5. There are two ways to stake Ether in the new network: directly or through special services. In the first case, you should have at least 32 ETH and be capable to launch a node.
A network node is a piece of software that monitors what happens in the cryptocurrency network, votes for new blocks and gets rewards. They gather coins from users and stake them. Then they distribute rewards according to provided shares and charge fees. For example, Binance is one of the platforms that offer such services. Thanks to PoS, the network can be protected without huge amounts of electricity needed to power GPU mining rigs.
As a result, the environment will benefit from it. With that being said, major industries like construction consume more energy and pollute the environment even more. Those who live in countries with high electricity rates will appreciate it. Especially in Europe, where electricity rates have recently gone up. Overall, the cryptocurrency industry will benefit from it: just in spring Bitcoin was criticized because of excessive amounts of energy wasted on mining.
Another advantage is node maintenance. Plus, if one of the rig parts breaks, it will take you a lot of time to detect the problem. But if you have a node, you just need to upgrade it to the latest version. As we already mentioned above, you need 32 ETH for staking without intermediaries.
So best case scenario, you can expect to redeem your deposit in 6—12 months. For example, Binance offers much higher interest rates on locked savings. And they also last for several weeks which would surely make investors happy. Another important downside of staking is penalties. The first penalty was issued on December 3, We agree that network safety is crucial, but beginning validators may lose money just out of ignorance. It can also share links to download mining programs along with their settings.
For example, here is a page with different GPUs and their payback. You can even enter the price at which a device is sold in your area to get even more precise results. You should just spend more time on finding a used graphics card. It is cheaper than the new one, which means that the payback period will be shorter and profitability will be higher.
