Talking about utility projects on Solana, $ARX is definitely worth mentioning.

@Arcium is building a "confidential supercomputer", which is actually a decentralized network that lets applications compute over encrypted data without exposing that data to validators, operators, or even Arcium itself.
Their Mainnet Alpha launched back in February, and the token only went live a few days ago.
Arcium combines MPC, ZKPs, and FHE into a configurable execution environment called MXE, rather than relying on a single privacy technology. That means devs can choose the right balance of security and performance depending on what they're building.
Some of the things they're enabling:
➜ Confidential smart contracts and apps on Solana
➜ Private DeFi primitives like dark pools, sealed bid auctions, and confidential settlement
➜ C-SPL, a confidential token standard that hides balances and transfer amounts while remaining composable with Solana apps
➜ Blackthorn, their confidential AI platform where prompts, model weights, datasets, and outputs stay encrypted throughout inference and training
Blackthorn is probably the most interesting part as it runs on existing NVIDIA H100, H200, B200, and HGX GPU infrastructure using software.
This expands the available confidential AI compute market by roughly 2,500x, since it can tap into the existing global NVIDIA GPU supply instead of waiting for specialized confidential hardware.
$ARX is used to stake nodes and to pay for confidential computations. You need the token to access the ecosystem.
Backed by names like Jump Crypto and Coinbase Ventures, with production apps already being built, this might be on the scale of $VVV.
Privacy is something that crypto desperately needs. And @Arcium is building their unique solution.
