Fashion is a cycle, and Crypto is a cycle. Maybe the cycle will no longer be there, but the imitation disk will be immortal.
The crypto supercomputing project Arcium on Solana chose Coinlist for the community round, which reminded me of the Coinlist quota script battle from 2017 to 2021, scientists and novice villages of the Maozhu Party.
A new generation beats the old one, but Arcium changed his banner three times, and struggled to find a way out for himself. He escaped the Solana Meme season by chance. I don’t know if he can realize his dream in the BSC Meme season.
Previous life: The dark pool where the library was removed and ran away. ElusivIn three sentences, we can summarize why Elusiv transformed into Arcium:
Do you know that Arcium is not my true surname, Elusiv is the original family;
MPC encryption based on data is disguise, and dark pool is the old business;
Privacy 1.0 is a personal private state, and Incarnation 2.0 emphasizes shared collaboration.
Elusiv started from Solana Hackers. In the early days, it was Zcash, Monero, Tornado Cash and other Solana imitation disks with encrypted privacy, focusing on ZK/FHE/MPC to build Dark Pool services.
Dark pool services are not complicated. Like the dark web, they refer to deep behaviors outside the surface, which has a deep feeling. Dark pools are essentially an anonymous trading behavior of traditional institutions or large individual traders over the market to avoid fluctuations in the secondary market.
On the blockchain, an open and transparent ledger system allows all transactions to be made public, which is also the source of MEV, so there are specific needs to transfer to anonymous transactions.
But as mentioned earlier, there is no essential difference between Privacy 1.0 and Coin Mixer, Monero, etc. at this time, after Tornado Cash is regulated, it would be a provocation to the US authorities, so Elusiv's code was suspended 2 years ago.
If you search for Dark Pool and FHE on @ArciumHQ, you will find that they focus on two things: talking about the advantages of MPC over FHE, mainly because of computing efficiency and cost, and secondly, they are optimistic about Dark Pool in the long term, but in the early name of Elusiv, they are now using Arcium.
However, there is no absolute advantage or disadvantage in technologies such as MPC/FHE/ZK/TEE, but more because of the differences in application scenarios. MPC focuses on trusted computing between multiple subjects, FHE focuses on the calculation behavior after encryption, while ZK ensures the validity of data before encryption.
In fact, it can be said that all kinds of privacy technology-oriented projects are not easy now, so why target each other? To expand the market together is a more win-win choice. But this is not the most effective program. After Tornado Cash ushered in a turnaround, Arcium began to advocate Dark Pool again.
It is difficult to do projects, and it is even more difficult to do famous projects. It is necessary to be tempered by the market and still be like the first love; it is difficult to be a retail investor, and it is even more difficult to be a retail investor who makes money. It has to be explained word by word in "The Huanglongjiang Sect is all with Bluetooth".
This life: Parallel FHE career conversion encryption supercomputerArcium has its own ideas about data-based privacy.
Simplely put, Arcium considers how to combine blockchain features with MPC. The answer is also very simple. Since MPC requires multi-party computing and blockchain needs to run multiple nodes, then combining the two is a multi-party execution environment (MXEs, Multi-Party eXecution Environments).
Using this as a benchmark, parallel execution technology, combined with FHE/ZK and other technical features, we can create a fast and secure blockchain encryption system.
If you are interested in parallelization, you can read the old article that has not been slapped in the face: Parallelism is not only EVM, high-performance L1 (Sui) vs. Ethereum L2?
But these are not particularly important. Just like Nillion, the lack of scenario support for privacy technology is the core issue. The AI, DePIN and DeFi selected by Arcium can be used as gimmicks for financing and issuance of coins. Only dark pools and privacy transactions (mixed coins) in the DeFi field have real market demand at present.
Arcium claims to be 10,000 times faster than FHE architecture, and it doesn't make any sense, because blockchain demand for FHE is zero, so ten thousand times zero is zero.
I am not denying Arcium or MPC/FHE Technology, but their forward needs are not clear, and the project party can only look for non-real needs under the pressure of issuing coins, just like junk coins being repurchased.
The afterlife: Free Solana Privacy 2.0But things will always turn around. Helius once contributed the most easy-to-understand technical articles of Solana 2.0, and is now redefining the concept of Solana Privacy 2.0. Although I don't believe this, it sounds reasonable.
There is only one core: Privacy 2.0 is multi-party privacy, typically a shared private state. In other words, it is MPC. To be more specific, it is a collection of concepts of Arcium:
arxOS is an encrypted operating system that summarizes the computing power of Arcium nodes;
MXE is a computing execution environment used to make secure computing happen on Arcium;
Arcis is a Rust-modified programming language, just like the relationship between Move and Rust.
I really want to complain here, including StarkNet, Move, and Arcis are all Rust-modified. Perhaps in the view of the project, it can maximize the effectiveness of customized languages, but it will not have any practical effect except to increase the burden on developers.

In fact, privacy AI may most likely not require technologies such as MPC/FHE. If LLM can be small enough, MCP can become the de facto industry standard, which can directly meet the daily needs of individual users, and does not need to overexpose privacy.
If privacy or private AI refers to the LLM deployed by a company, entity or individual, then the interaction delay and computing power consumption brought by MPC/FHE technology can be inefficiently added. MPC's cheap big bowl is relative to FHE In other words, its own computing power consumption is not cheap.
Secondly, the problems faced by dark pools and privacy transactions (anonymous small transfers, mixed coins) are mainly supervision, and the cost issue is the problem. Dark pools are exclusive to large investors. The battle between the dark pools and SECs in the traditional financial markets has been ongoing, and the same is true for coin mixers.
Although Trump has shown that even if I die, the spirit of making money after I die, the dark pools on the chain are really rising. Should I learn the privacy model of RailGun and the official reporting, then the only ones who hurt the peace between big investors are injured.
The United States has officially given up on Tornado Cash However, after this battle, pure and classical true privacy solutions will not become the mainstream of the market again. TRM Labs and RailGun’s active and passive compliance can be controlled by regulatory authoritiesOn-chain behavior.
The only real thing is the anonymous small transfer of funds in the market space, but ordinary individuals do not pay extra for privacy. You can treat it as a service, but it is difficult to use this to support the complete PMF logic.
ConclusionArcium entered the TGE process, marking the end of the classical privacy project, which is even more classic than Tornado Cash's overturn. From then on, the project will take the initiative to set limits and the boundaries will be established.
