The valuation of blockchain tokens has always been a hot research topic within the crypto ecosystem.

Regarding the valuation of Bitcoin, many articles have explored the relationship between the price of the coin and the shutdown price of mining. However, when it comes to Ethereum and the broader blockchain networks based on POS or DPOS consensus mechanisms, while there are numerous articles discussing what factors the tokens are related to, there seem to be few that are logically convincing.

Taking Ethereum as an example, many times, our estimates of Ethereum's (future) price are simply made by comparing it to Bitcoin's market capitalization.

This method cannot be said to be baseless, but I believe it lacks consideration of the essence and characteristics of Ethereum, as the value acquisition of Ethereum is distinctly different from that of Bitcoin.

For instance, many people say Bitcoin is "digital gold," while Ethereum is "digital oil."

If the distinction between the two is akin to that between "gold" and "oil," can Ethereum's valuation be simply compared to Bitcoin in the aforementioned manner?

This is clearly inappropriate.

Recently, I read an article by Messari about the "economic security" of POS/DPOS blockchains.

The so-called "economic security" refers to the relationship between the value of the tokens used for collateral in POS/DPOS blockchains and the security of the blockchain.

For example, if the current circulating supply of Ethereum is 100 million tokens, and one-third of that is used for POS collateral. If the current price of Ethereum is $3,000, then the value of the Ethereum used for collateral is $100 billion. The "economic security" of the Ethereum blockchain is guaranteed by this $100 billion.

The core discussion of this article is whether "economic security" is as important for the security of POS/DPOS blockchains as many in the industry imagine.

This topic is not directly related to the valuation of Ethereum. However, one scenario mentioned in the article made me wonder if the described method could be used to value Ethereum or the broader POS/DPOS blockchain tokens.

The author of the article hypothesized the following scenario:

For instance, I have $10 million in USDC, but the collateral value of the POS blockchain where my $10 million USDC is located is only $100. In this case, would I dare to put these USDC on this blockchain?

Definitely not.

Why?

Because if the total value of the tokens collateralized by all nodes is only $100, then a malicious actor could easily bribe these nodes with $1,000 (10 times the collateral value) to plunder the $10 million USDC on the chain.

For these nodes, even if they collude with the malicious actor and cause their $100 collateralized tokens to be completely confiscated, the $1,000 bribe they receive is still a significant temptation.

For the malicious actor, the cost of $1,000 is negligible compared to the $10 million USDC gain.

So while we may debate how much "economic security" is needed to sufficiently convince people that this POS blockchain is secure, we can at least draw a bottom line:

The collateral value of this POS blockchain must not be less than the total value of the assets on the chain.

Following this line of thought, let's attempt a very conservative estimate of Ethereum's price.

I checked the data on defillama (https://defillama.com/). As of the time of writing, the total value locked (TVL) on the Ethereum mainnet and various layer two expansions (OP-Rollup and ZK-Rollup) is approximately $70 billion.

The Ethereum Foundation, including Vitalik, estimates that one-third of the future circulating tokens of Ethereum (120 million tokens) may be used as collateral. If we calculate based on today's Ethereum price ($3,200), the collateral value of one-third of the circulating tokens would be approximately $128 billion.

So the current situation of Ethereum is that about $128 billion of "economic security" is safeguarding a total of $70 billion in assets on the Ethereum mainnet and its layer two expansions.

If we believe that the future crypto ecosystem will recreate an on-chain economy for human society, assuming that the TVL of this economy within the Ethereum ecosystem could reach our country's foreign exchange reserves in 2023 ($3.24 trillion), then the value of the collateralized tokens in the Ethereum blockchain would need to be at least $3.24 trillion.

If we are conservative and assume that this $3.24 trillion is the value of the entire circulating supply of Ethereum tokens, then the price of Ethereum tokens would be approximately $27,000.

In this calculation process, the data and information I referenced are entirely based on my own preferences; this is not the key point. The key is that this valuation approach can generally outline a valuation floor for blockchain ecosystem tokens.

In fact, it can be used not only to assess the future price floor of Ethereum but also to evaluate the future price floor of any POS/DPOS blockchain token.

Writing this somewhat "fantastical" valuation method today is purely inspired by reading that article, prompting me to think about valuation from another perspective.
