Ethereum 2.0 is a necessary upgrade for the future of Ethereum. So why does Ethereum need to upgrade and what happens to ETH supply after merge. Let’s find out by reading the article below.
Why does Ethereum need to upgrade?
Blockchains are usually designed with decentralization as a core principle, rather than relying on a central authority. The benefits of a decentralized blockchain include being permissionless, trustless, and more secure by resisting single points of failure.
As blockchains grow in popularity, platforms must ensure they can meet the global demand for transaction processing speed, also known as scalability requirements. Failure to do so could lead to network congestion when blockchain capacity is overwhelmed by the number of pending transactions. Typically, this results in higher transaction fees.
As Vitalik Buterin acknowledged, the pre-merger Ethereum network was unable to meet scalability criteria due to its proof-of-work consensus mechanism. Proof-of-work blockchains tend to be harder to scale for a number of reasons. First, there is a limit to the number of transactions that a block can verify in each block. Second, blocks must be mined at a constant rate.
For example, Bitcoin is designed to mine a block every 10 minutes on average, according to the mining difficulty that is automatically adjusted by the protocol. While Bitcoin is designed to be highly secure, block times combined with transaction limits per block can cause network congestion when demand increases. This often results in a significant increase in transaction fees and confirmation times.
What happens to ETH supply after merge?
Execution layer issues are zero since the merge. Under the upgraded consensus rules, Proof of Work is no longer an effective means of block production. All execution layer activity is packaged into "beacon blocks", which are issued and attested by proof-of-stake validators. Rewards for attesting and publishing beacon blocks are calculated separately on the consensus layer.
Today, the issuance of the consensus layer continues as before The Merge, with small rewards for validators who attest and propose blocks. Validator rewards continue to accumulate into validator balances managed within the consensus layer. Unlike checking accounts that can transact on mainnet, these are standalone Ethereum accounts and validator funds cannot be withdrawn/transferred until the upcoming Shanghai upgrade. This means that while new ETH is still being issued, 100% of consensus layer funds remain locked and cannot enter the market until this upgrade occurs.
When validator withdrawals are enabled, stakers will be incentivized to withdraw their earnings/rewards (with balances over 32 ETH), as these funds will not increase their stake weight (maximum 32).
With withdrawal enabled, stakers can also opt out and withdraw their entire validator balance. In order to ensure the stability of Ethereum, there is an upper limit on the number of validators who can leave at the same time. Based on the total amount of ETH staked at that time, only six validators can exit in a given period (6.4 minutes). As more and more validators withdraw, the maximum number of withdrawing validators will be gradually reduced to four to intentionally prevent large amounts of volatile ETH from being withdrawn at the same time.
I hope this article will help you to learn why does Ethereum need to upgrade and what happens to ETH supply after merge. Ethereum is far from a finished product. Upgrades like The Merge and Shanghai are carefully planned and orchestrated to ensure the blockchain can support the growing demands of its users and developers.
