Phase 0: One Small Step for Ethereum, One Giant Leap for Decentralised Networks

As the Ethereum networks get ready to launch Phase 0 of Ethereum 2.0, we discuss the importance of this new technology and its impact on the price of ETH.

This transition is one of the most ambitious and challenging tasks in the blockchain industry with the potential to revolutionize decentralised networks.

What is Ethereum 2.0?

In simple terms, Ethereum 2.0 or Serenity, is a network update that aims to make Ethereum more scalable by introducing new PoS protocols along with upgrades such as, sharding, virtual machine, and more. In this article, we guide you through the updates and changes in Ethereum and the expected price impact.

Ethereum was the first-ever blockchain designed for smart contract usage on its platform, enabling individuals to build decentralised apps (dApps) on top of the blockchain platform, similar to an application on an Android or iOS system.

Inspired by Bitcoin, Ethereum incorporated proof-of-work (PoW) as its consensus mechanism; however, with a high rate of dApp usage (Crypto Kitties), PoW caused the Ethereum blockchain to bloat [1], slowing down the network. To overcome this scalability issue, Ethereum is set to transition from the PoW to PoS consensus mechanism along with other network upgrades such as sharding [2] and eWASH.

Ethereum 2.0 is set to be rolled out in phases (Figure 1), and the expected release date for Phase 0 is later this year, whereas the dates of other releases have not been announced yet.

Ethereum 2.0 Operation Simplified

From an architectural standpoint, Ethereum 2.0 will appear similar to Figure 2. Each transaction and smart contract execution will occur via the Virtual Machine (eWASH). The execution results generated through the virtual machine will be kept in a block within a shard chain. Multiple shard chains [3] will exist and operate in parallel. In the final stage, all shard chains will be connected to a beacon chain where different shards will be compiled and stored. In the following section, we learn about Ethereum 2.0’s beacon chain.

Phase 0: Beacon Chain and its Conditions

The Beacon Chain will be the first release of the Ethereum 2.0 update. It will implement PoS mechanisms and manage the registry of validators within the network. During this phase, both the Ethereum (current blockchain) and Ethereum 2.0 blockchains will exist in parallel. In Phase 0, the Beacon chain will be of limited use, as no transactions, smart contracts, or dApps will be running. This is to ensure that the PoS mechanism undergoes rigorous live testing and attracts sufficient validators for the later phases. During this phase, anyone who intends to become a validator on the network can convert their 32 ETH to 32 ETH2 [4].

Economics of Ethereum 2.0

During Phase 0, two Ethereum chains will exist simultaneously, one PoW and another as PoS, which will run independently. Both networks will have their own supplies and inflation rates; therefore, with the introduction of Ethereum 2.0 the overall inflation rate of Ethereum (i.e. Ethereum 1.0 and 2.0 combined) will increase until both chains merge (i.e., Phase 1.5). Ethereum 2.0’s rate of issuance will directly depend on the number of ETH2 staked in the network at any time. The relationship between the supply and number of ETH staked in Ethereum 2.0 is defined as follows:

S = 181 × √SETH2

where S is the number of ETH supplied and SETH2 is the number of ETH2 staked. A higher rate of initial supply (when there are few validators) will incentivise ETH holders to move to Ethereum 2.0’s Beacon chain and earn higher rewards. Figure 3 shows the relationship between the supply and number of ETH staked. The number of ETH2 staked is directly proportional to the validator reward (supply).

Ethereum 2.0 staking can be performed either at home using a personal or dedicated computer or through cloud computing. Both methods have their advantages and disadvantages with respect to fixed costs, variable costs, uptime, reliability, etc. Figure 4 shows how much a validator is expected to earn under both home and cloud-based operations given various levels of total ETH2 staked and other assumptions. Readers can refer to the staking calculator sheet to better understand and customize other assumptions according to their requirements. These rates are subject to variable changes, and the reader can refer to this article by SEBAEthereum 2.0: Where the rubber meets the road, to better understand these variables.

Impact of Ethereum 2.0 on ETH

Now that we understand the working dynamics and conditions within the Ethereum 2.0 Beacon Chain, we discuss how the launch of Phase 0 can impact the price of ETH. Multiple factors may increase the price of ETH in the short run, some of which are described below.


Ethereum 2.0 requires validators to convert ETH to ETH2 and transfer them to the new PoS blockchain; further, ETH2 will be locked until Phase 2 is launched. This will result in a decrease in Ether’s circulating supply in the PoW chain. In the Ethereum community, the Ethereum Improvement Proposal (EIP) 1559 suggests decreasing the supply of Ethereum on the PoW network by burning a major chunk of the transaction fee. Which will reduce the fee that miners receive for validating transactions, whilst the fee paid by users remains the same. This is intended to incentivise users to move to the PoS-based blockchain. However, this proposal has not yet been implemented. In case it gets implemented before Phase 1 is launched, a reduction in the supply rate may occur in the PoW-based Ethereum. Overall, a reduced circulating supply of ETH should put upward pressure on ETH’s price.


In Phase 0, the Beacon chain has zero real-world usage, as no transactions, smart contracts, or Dapps can be executed. Because of this, the demand for Ethereum will not decrease. On the contrary, the demand for Ethereum may show an increase in the short-term, as investors, speculators and validators begin purchasing ETH before the Beacon chain launches. This interest in accumulating Ethereum can already be observed: Year-to-date, Grayscale has purchased approximately 873,723 ETH.

Furthermore, the network currently shows a two-year high in terms of the network transaction count and at a lower price (Figure 5).

In the short to medium-term, the demand side is creating bullish pressure. The supply side is also creating bullish pressure in the medium-term, assuming EIP 1559 will also be implemented. Therefore, ETH may show a price increase in the short- to medium-run. Table 1 shows estimates of the price impact on ETH given that the circulating supply decreases with the number of ETH converted and staked in Ethereum 2.0 and assuming that the total market capitalisation and demand remain constant.

In the longer run (i.e., after Phase 2) the price impact of Ethereum 2.0 may be bearish on ETH, as PoW network’s utility will decrease, when transactions, smart contracts, and Dapps are initiated on the PoS network. Note that migrating the Ethereum network to PoS will be time-consuming and difficult and result in the locking up of capital (staking). Therefore, one should avoid staking all Ethereum holdings on Ethereum 2.0. For long-term investors, it would be prudent to stake some of their ETH in Ethereum 2.0 to benefit from the high initial returns while also keeping some ETH on the PoW chain. These investors should also consider that this transition is one of the most ambitious projects in the digital assets space. A failure to deliver or any delays can negatively impact ETH’s price and lead to the locking up of capital on Ethereum 2.0 for an indefinite time period. Investors and traders can also consider the option of holding Ethereum and benefiting from the likely short to medium-term price increase up until the Beacon Chain release.

To become a validator

The barrier to entry to becoming a validator on Ethereum 2.0 is relatively low. To become a validator, one must fulfil certain financial and hardware conditions. The entire process will be clarified by release of the Beacon chain. However, the following are basic requirements for becoming a validator on the Beacon chain.

  1. The validator must convert 32 ETH into ETH2 using this deposit contract.
  2. Each validator must stake 32 ETH2. More than 32 ETH will not result in added returns, and therefore staking should be performed in multiples of 32.
  3. Validators can use cloud computing or personal hardware to stake. The following personal hardware specifications are recommended [5]:
    1. Processor: Intel Core i7–4770 or AMD FX-8310 or better
    2. Memory: 8 GB RAM
    3. Storage: 100 GB available space on SSD
    4. Internet: Broadband connection


Now that the Bitcoin reward halving is completed, many investors are eyeing Ethereum as the next trade and investment opportunity. A smooth release of the Beacon Chain will be a positive step towards the migration of Ethereum from PoW to PoS. In the medium- to short-term, we expect ETH’s price to increase, as the PoS-based Ethereum 2.0 will not be fully functional until Phase 2 is implemented. During this time, Ether’s reduced supply and increased demand should increase its price. In contrast, in the long-term, the launch of Ethereum 2.0 may lead to a price decrease as users migrate from the PoW to the PoS chain. However, predicting these changes is difficult, because of the many factors affecting coin swap and interoperability functions.
