Ethereum staking explained: Things to know in 2021

Ethereum staking will become the Ethereum validation procedure. For now, Ethereum is based on Proof of Work. Complete transition to Ethereum 2.0 will mark the beginning of the phase when Ethereum as an ecosystem switches over to Proof of Stake. This will make the process of mining Ethereum on Eth2 obsolete. Staking has already begun.

What is Ethereum?

Ethereum is an ecosystem. It is predominantly a blockchain. The cryptocurrency called Ether (ticker: ETH) is this blockchain’s native token and transactions on this network are done using ETH. ETH also has external value for trading, payments, and investment. As previously stated on Redot exchange, this is the second highly popular crypto among crypto traders.

Apart from ETH, the larger Ethereum network also boasts of decentralized apps (dApps), smart contracts, and NFTs (non-fungible tokens), apart from other cryptocurrencies that are based on the ERC-20 protocol.

Ethereum is a group of technologies that makes transacting online anonymous, safer, and peer-to-peer. It’s also decentralized, meaning no central authority can influence the development of Ethereum. All decisions are community-driven.

Proof of Work vs. Proof of Stake

Any blockchain depends on its users running nodes to confirm and validate blocks. A blockchain is, at the end of the day, a chain of blocks. Blockchains can only survive if enough people are confirming and validating these blocks.

Transactional data, NFTs, tokens, etc. are then developed and run on this blockchain.

There are two popular methods of validation/confirmation consensus when it comes to blockchains: Proof of Work and Proof of Stake.

In a Proof of Work system (such as Bitcoin Core – BTC), people need to “mine” the cryptocurrency using specialized hardware (and sometimes, consumer hardware – for example Monero can be mined using normal processors whereas Ethereum can be mined using gaming GPUs).

Mining means doing complex mathematical computations.

Once a block is confirmed, it’s added to the blockchain, and the miner who discovered or mined the block is rewarded. Usually, mining is done through pools and not solo.

In comparison, Proof of Stake doesn’t require mining. Instead, blocks are validated after being randomly assigned to people or companies that “stake” their cryptocurrency with the network. Staking will make the funds unusable until you take them out of staking.

How Proof of Stake solves Ethereum issues?

There’s a downside to mining and a Proof of Work system. GPUs and ASIC machines that are used to mine consume a large amount of electricity and require a lot of cooling. It’s estimated that BTC mining costs the world nearly 143 terawatt-hours annually – which is more than what Argentina consumes. In comparison, Ethereum mining currently consumes 50 terawatt-hours annually (comparable to the energy consumption of Peru).

Note that these figures are far less than the energy consumption of gold mining, banking systems, or even transmission waste.

Proof of Stake makes Ethereum a greener and more environment-friendly technology by decoupling it from its dependence on mining using power-hungry hardware.

It additionally makes the network more secure as power will be held in the hands of stakers and not miners, who are more responsible for their decisions.

How do I start staking?

You need 32 ETH to become a validator. Note that going offline, passing incorrect judgments on block validation, and other malicious actions will lead to the loss of your staked ETH. You can also join a pool if you don’t have 32 ETH. The rewards will be split among all members of the pool.
