The Ethereum Merge is completed: Here's what's next
The Ethereum blockchain has efficiently accomplished its shift away from proof-of-work to proof-of-stake (PoS) consensus following the merge of the Mainnet and the Beacon Chain.
The Merge happened on Sep.15 because the community shifted to PoS seamlessly, seeing hardware-based miners replaced by validators that stake Ether (ETH) to course of transactions, add new blocks and keep the community.
Essentially the most pertinent query within the cryptocurrency area is, what occurs subsequent? The Ethereum Basis has all the time labored on an extended roadmap of improvement milestones, and The Merge isn’t any totally different.
Glad birthday beacon chain!
This is an up to date roadmap diagram for the place Ethereum protocol improvement is at and what’s coming in what order.

Ethereum’s co-founder Vitalik Buterin beforehand outlined a five-step, gradual course of that can carry the good contract blockchain to what he described because the “endgame” of Ethereum’s improvement.
The top aim would see the community able to excessive block frequency and block measurement in addition to the flexibility to course of 1000’s of transactions per second whereas remaining sufficiently trustless and censorship-resistant.
The Merge
The Merge was step one on this five-part course of, which has since been elaborated upon by plenty of Ethereum builders, ecosystem individuals and commentators. The important thing change of the Merge is the drastic discount in energy consumption, lowering Ethereum’s vitality utilization by 99%.
Hours earlier than the Merge happened, Buterin quoted Ethereum researcher Justin Drake’s estimate that the occasion would additionally cut back world electrical energy consumption by 0.2%.

The second essential change led to by the shift to PoS is the lowered issuance of ETH by way of rewards to validators for his or her work sustaining the community, turning ETH right into a deflationary asset.
The Surge
2023 is earmarked because the yr that Ethereum will implement sharding, an essential step in growing the scalability of the blockchain’s potential to retailer and entry knowledge.
The Ethereum Basis describes sharding as the method of separating a database horizontally to unfold the community’s workload. Ethereum will use sharding in synergy with layer-2 rollups by splitting the massive quantity of knowledge throughout the community.
That is envisaged to cut back community congestion and enhance transactions per second. It’s the decentralized different to creating a database greater, assuaging the necessity for validators to retailer all the community’s knowledge, themselves, which might require highly effective {hardware}.
It additionally implies that the common consumer might run an Ethereum node or purchasers on private units similar to PCs and cellular units, making the community extra strong because of its elevated decentralization.
The Verge, Purge and Splurge
The final three steps in Ethereum’s ongoing improvement following the Merge are set to happen over the following few years.
The verge is the third a part of Ethereum’s ongoing roadmap outlined by Buterin. With out getting too technical, this step will contain the introduction of verkle bushes, which can optimize knowledge storage and node measurement.
As Buterin explained in a deep dive in June 2021, Verkle bushes serve an analogous perform to Merkle bushes, which complete all transactions in a block and produce proof of the complete set of knowledge for a consumer trying to confirm its authenticity:
“The important thing property that Verkle bushes present, nevertheless, is that they’re much extra environment friendly in proof measurement.”
The cryptography is barely extra sophisticated, however Buterin highlighted that the discount in knowledge measurement of proof could be enough to make stateless purchasers viable.
The Purge will contain eradicating spare historic knowledge in an effort to alleviate community congestion by purging superfluous knowledge. This can basically cut back the quantity of knowledge wanted to be saved by a validator, with Buterin touting this step permits the community to deal with round 100,000 transactions per second.
What else ought to I do know?
As Cointelegraph beforehand explored, stakers trying to develop into full validators of the Ethereum blockchain must commit 32 ETH to take action. A standard false impression was that these stakers may take away their staked ETH as soon as the Merge was full.
To make sure community stability, validators will solely be capable of withdraw their staked ETH as soon as the Shanghai improve takes place, which is earmarked to happen within the subsequent 12 months. Validators can even obtain charges for processing transactions (miner extractable worth) — that are credited to their non-staking validator account.
