Overview
Oasis is a Layer 1 blockchain focused on privacy and confidential computing. It was founded by Dawn Song, a computer science professor at UC Berkeley known for her security research, and launched its main network in November 2020.
Oasis’s pitch: most blockchains make all data public, which is a problem for businesses, personal data and AI. Oasis lets smart contracts keep data secret while still running on a blockchain.
How it works
Oasis separates its system into a base layer for consensus and several ParaTimes (parallel runtimes):
- Sapphire, a confidential EVM: developers write normal Ethereum-style contracts, but their data and inputs are encrypted. It uses trusted execution environments (TEEs), secure areas inside computer chips.
- ROFL (Runtime Off-chain Logic), which lets heavy computing such as AI models run off the blockchain while producing results that can be verified on-chain.
The ROSE token
| ROSE at a glance | |
|---|---|
| Maximum supply | 10 billion ROSE |
| In circulation (Oct 2026) | about 8.1 billion |
| Price (29 Oct 2026) | about $0.0068 |
| All-time high | about $0.60 (January 2022) |
| Market cap | about $55 million |
ROSE pays transaction fees, is staked to secure the network and is used in governance.
Risks
- Low usage. DeFi activity on Sapphire is close to zero, according to DeFiLlama.
- Hardware trust. TEEs have had security flaws in the past; privacy depends on the chip makers’ security.
- Competition. Privacy and AI computing are crowded fields (Secret Network, COTI, Aztec, EigenCloud and others).
- Small size. ROSE’s low market value makes it volatile.
Oasis vs. the competition
| Oasis | COTI | Zcash | |
|---|---|---|---|
| Privacy approach | Trusted hardware (TEEs) | Garbled circuits | Zero-knowledge proofs |
| Smart contracts | Yes (confidential EVM) | Yes (on Ethereum) | No |
| Focus | Private apps, AI computing | Private apps | Private payments |
Our verdict
Oasis has strong research roots and a real technical offering for private smart contracts and verifiable AI. But adoption remains very low, and ROSE has lost about 99% of its value. ROSE is a very high-risk investment: invest only what you can afford to lose.
