This is why many cryptos either use proof-of-stake or proof-of-work to validate crypto transactions. Both are essentially different algorithms that allow users to add transactions and record them on a blockchain, an immutable public ledger. There are several other potential future upgrades to the fork choice rule that could add to the security provided by proposer-boost. One is view-merge, where attesters freeze their view of the fork choice n seconds before the beginning of a slot and the proposer then helps to synchronize the view of the chain across the network. Another potential upgrade is single-slot finality, which protects against attacks based on message timing by finalizing the chain after just one slot. When the network performs optimally and honestly, there is only ever one new block at the head of the chain, and all validators attest to it.

  • As a result, many of the people entering the staking ecosystem are institutional investors, with the number of wallets staking $1 million or more worth of Ether steadily climbing.
  • It’s why it’s such a challenging task to switch from one algorithm to another.
  • Technically, Ethereum started its journey to proof of stake in December 2020 with the launch of deposit contracts and the activation of the so-called Beacon Chain, a basic proof-of-stake coordination mechanism.
  • A “reorg” is a reshuffling of blocks into a new order, perhaps with some addition or subtraction of blocks in the canonical chain.
  • For example, if 1 million ETH is staked, the max annual reward for each staker could reach 18.10%, however if 3 million Ether are staked, that annual reward rate would drop to 10.45%.
  • PoW is the original consensus mechanism for verifying transactions that bitcoin used.
  • This beacon chain was run alongside the proof of work chain until September 2022, when the two chains were integrated into a single proof of stake network.

CoinDesk journalists are not allowed to purchase stock outright in DCG. The network should theoretically become safer now that it’s now more expensive to validate transactions on the blockchain. If you want to activate validator software, you will have to stake 32 ETH . Nothing changed drastically for Ethereum users since The Merge was just an infrastructure upgrade. This means that wallets, addresses and transactions still work the same.

Proof of Stake Ethereum

A major criticism of cryptocurrency is that it has a negative impact on the environment. The White House has been calling for crypto mining standards to reduce energy usage. With the government in China cracking down on crypto mining, the U.S. has become a hub for miners.

However, the bulk of Ethereum’s stake currently belongs to a handful of large actors – fueling concern that control over the chain is becoming too centralized. Data from Nansen indicates the number of unique staking depositors stands at roughly 92,500. Data sourced from BeaconScan shows that the number of active validators is about 498,000.


Switching from proof-of-work to proof-of-stake will add a few complexities to the shard chains. These are separate blockchains, and they need validators to pass through transactions and add new blocks. The avalanche attack is mitigated by the LMD portion of the LMD-GHOST fork choice algorithm.

The transition process used to take this specification into effect is a more sophisticated version of a hardfork – the regular procedure of applying backwards incompatible changes in the Ethereum network. This process has multiple successive steps instead of the normal block-height point condition of simpler hardforks. You could write a book on the details of The Merge and proof-of-work versus proof-of-stake. But of more importance is that Ethereum successfully carried out The Merge and is about to undergo another upgrade, a sign that progress doesn’t always have to take years.

The Merge: The Timeline

If the company can achieve the set goals, the entire community will be assured that the consensus protocol might be worthwhile. Moreover, this shift allows many more people to take part in a larger and much broader ecosystem. For stakers, the shift would mean they would earn the transaction fees instead of being awarded block rewards for solving complex equations. And although the rewards lessen, the entry bar significantly lowers as well. The PoS protocol also speeds up the processes in the ecosystem, making it easier for users to conduct transactions instantly, improving dApps user experience. Proof-of-stake offers better energy efficiency, more scalability, and a decrease in hardware requirements, making cryptocurrencies more accessible.

You’ve probably heard of cryptocurrency miners who validate transactions on proof-of-work blockchains like Bitcoin. If Ethereum were to be considered as a security, then ether and every application on the blockchain would have to get registered with the SEC.

Removing block rewards

As The Merge is the most radical upgrade for Ethereum tokenomics, let alone technology, many ETH holders and potential investors are wondering whether it will somehow affect the Ether price. Last but not least, in the coming months, Ethereum will most likely activate sharding. The blockchain will be split up into a network of shards, or interconnected sub-chains. Not unlike NEAR Protocol and Harmony , this update will improve the performance and throughput of the Ethereum mainnet. To ensure a smooth transition to proof-of-stake consensus, Ethereum core developers activated The Merge in a number of closed and public testnets. Since December 2021, Ethereum enthusiasts have emulated The Merge specifications in Kintsugi and Kiln purpose-made testnets.

Popular cryptocurrencies such as Bitcoin and Ethereum Classic use PoW as a consensus protocol. In this protocol, miners competing to create new blocks on the blockchain network must go through many transactions and find the hash code corresponding to the last block. Decentralized finance offers traditional financial instruments in a decentralized architecture, outside of companies’ and governments’ control, such as money market funds which let users earn interest. DeFi applications are typically accessed through a Web3-enabled browser extension or application, such as MetaMask, which allows users to directly interact with the Ethereum blockchain through a website. Many of these DApps can connect and work together to create complex financial services. As the protocol is upgraded, the difficulty bomb is typically pushed further out in time.

Security Considerations

With the use of smart contracts, developers have created applications that not only let users stake their Ethereum but also provide them with a token unique to that pool. They then get the benefit of earning interest on their staked Ethereum and have the ability to earn profits in other ways. The amount of staked ETH has climbed about 16.68% since the Merge in September, when Ethereum abandoned its old proof-of-work consensus mechanism. The Merge fully transitioned ethereum speedier proofofstake the Ethereum blockchain to a proof-of-stake consensus mechanism, which abandoned proof-of-work’s energy-intensive crypto mining process in favor of today’s staking system. Ethereum’s PoS mechanism picks a single validator from the total validator set to be a block proposer in each slot. This can be computed using a publicly known function and it is possible for an adversary to identify the next block proposer slightly in advance of their block proposal.

We hope this helps you grasp how the proof of stake protocol works and it serves as a helpful pre-requisite before diving into a consensus client code or as part of your development process. There are also many other technical benefits to celebrate the upgrade, but the benefits are lost to most of the community. It is time — especially now that proof of stake is protecting hundreds of billions of dollars — to write more accessible material on how it works, why it is important, and what exciting features await us. Even though several big and popular cryptocurrencies, such as Tezos, Cardano, Algorand, use the proof-of-stake mechanism, these are smaller projects compared to Ethereum. Each shard chain will have a shared understanding of the blockchain’s state.

Ethereum Moving from Proof of Work to Proof of Stake

Meanwhile, the remaining malicious validators hold back their attestations. Then, by selectively releasing the attestations favoring one or other fork to just enough validators just as the fork-choice algorithm executes, they tip the accumulated weight of attestations in favour of one or other fork. This can continue indefinitely, with the attacking validators maintaining an even split of validators across the two forks. Since neither fork can attract a 2/3 supermajority the Beacon Chain would not finalize.

Re-orgs could also be used to prevent certain transactions from being included in the canonical chain – a form of censorship. The most extreme form of reorg is “finality reversion” which removes or replaces blocks that have previously been finalized. This is only possible if more than ⅓ of the total staked ether is destroyed by the attacker – this guarantee is known as “economic finality” – more on this later. The proof-of-stake mechanism allows users of crypto to stake their crypto on the blockchain so that they can create their own validator nodes. The validator stakes their crypto on the network for a set period in order to be allowed to verify transactions.

Ethereum is by far the biggest competitor of Bitcoin due to its widespread usage in decentralized finance. On blockchain networks like Ethereum, there has to be a way to validate transactions in a decentralized manner, without a centralized authority, such as a bank. Currently, Ethereum, along with other popular cryptocurrencies like Bitcoin, use what’s known as Proof of Work . Because of these disadvantages, other alternative consensus mechanisms have been suggested throughout the years. This means that instead of committing electricity to run computers and try to win a contest, people will stake actual coins.

Today, you can earn as much as 301% when you stake your stETH in certain parts of the ecosystem,accordingto DeFi Llama. Its wide adoption in DeFi is likely one of the reasons why it’s so popular; of this type of offering (excluding centralized exchange-based equivalents), Lido commandsmore than 88% of the LSD market. The key message to take away from The Merge for HODLers is that you don’t need to do anything with your ETH holdings. So, be wary of anyone telling you that you need to “transfer” or “bridge” your ETH to the new network. Aside from this important fact, Ethereum’s move to Proof of Stake looks to have various benefits for users. For users who wish to, they will be able to swap their BETH back to ETH.

This should help Ethereum become further decentralized and more secure in the long run. Arguably one of the most significant events in crypto history, The Merge transitioned Ethereum from a clunky, energy intensive proof-of-work consensus mechanism to the more streamlined and efficient proof-of-stake method.

How Much Can You Make Staking ETH?

Passive income through staking rewards might also seem like a no-brainer to some who are long-term holders and don’t plan to immediately sell or trade their bags of ETH in the short term. For users who don’t mind the risks, staking can be a lucrative activity. While the rewards rates vary, MetaMask’s site claims users can earn a yield of about 5.22% per year on ETH deposits with Lido, and 4.59% with Rocket Pool. They provide a way for individuals to collaborate to fulfill the minimum mark of 32 ETH required to become a validator. Corresponding rewards are then divided pro-rata among pool participants. On December 1, 2020, Ethereum launched a separate proof-of-stake Beacon chain.

Compared with networks of similar evaluation the diversity of nodes, is quite good and the amount of staked FSN is high. Ether is the largest altcoin; only Bitcoin surpasses it by market capitalization. Additionally, through a process called “wrapping”, certain DeFi protocols allow synthetic versions of various assets to be tradeable on Ethereum and also compatible with all of Ethereum’s major wallets and applications.
