Investors awaiting Ethereum 2.0
In the backdrop of the technological advancement and growth of the digital payment system, cryptocurrencies are growing fast. Investors are now looking at it as a safe option amid the current volatile market situation. The cryptocurrency market is finally emerging and seems to be getting its due credit, and even authorities are keeping a tab on the market trends. The world is softening its attitude towards the cryptocurrencies.
Amid the bullish Ethereum trend, investors are waiting for the long-pending upgrade of the underlying network. Similar to bitcoin, blockchain is the underneath technology for recording Ether transactions. Currently, Ethereum works on "proof of work" model, where miners with specially-designed systems for ether transactions try to outdo each other in solving tricky mathematical puzzles to validate transactions. The winner in this competition gets awarded the Ethereum cryptocurrencies.

Transition to ‘proof of stake’ model: On Tuesday, the blockchain underlying the Ether network is set for an upgrade to the "proof of stake" model. Ether works on Ethereum blockchain, which runs smart contracts. Unlike bitcoin, the Ether acts as a fuel to allow smart contracts to run. After the upgradation, in order to validate a transaction on a new network, stakers, instead of miners, will be able to do the same. It means to begin a transaction, a staker, who already possess some Ether cryptocurrencies, will need to deposit 32 ether tokens of around USD 19,600 at the current price to crypto wallets with the use of the smart contract. The stakers, like crypto miners, will then be rewarded with Ether for validating transactions.
The upgradation is promising for Ether and projects related to it. The upgrade will increase the scalability, speed, and efficiency of the network.
