Privacy-first blockchain
Oasis Network swings hard at a different problem: most blockchains are transparent, which kills privacy for financial strategies, medical records, competitive data. Oasis lets you run contracts inside secure hardware enclaves—think Intel SGX—so you compute on sensitive data without broadcasting it to everyone.
Dr. Dawn Song, a security researcher from UC Berkeley, founded this. She recognized that enterprises would never use public blockchains for real secrets. Mainnet launched November 2020.
ROSE is the staking token and native currency. As of April 2026, Oasis ranks in the top 100 cryptos.
Building blocks
The architecture splits into two layers: consensus (validators coordinate) and runtime (applications execute). Multiple runtimes can run in parallel—Emerald (EVM-compatible) is one, but you can create others for specific applications.
The real trick is the trusted execution environment. Intel SGX is the main one. Your smart contract runs inside an enclave, shielded from the OS and even privileged software. The code executes as written. Nobody can snoop on memory.
You write contracts in Rust. They compute without exposing raw values to the outside world. Cross-runtime messaging exists for apps that span multiple runtimes.
Threshold cryptography splits keys across validators—no single entity controls the whole protocol. Privacy-preserving bridges connect to Ethereum.
Consensus and penalties
Byzantine Fault Tolerant Proof of Stake coordinates validators. Two-thirds of voting power must commit to lock finality. The protocol tolerates up to one-third malicious nodes.
Round-robin block selection weighted by stake. Validators earn rewards for honest blocks. Misbehavior gets slashed.
Time-locked futures let validators commit to blocks cryptographically, enabling rapid finality without extended voting periods.
Token supply and rewards
Max supply: 10 billion ROSE. Circulating: ~3.1 billion as of April 2026.
Inflation declines as staking grows. Block rewards fund staking returns. Delegators can earn returns without running their own infrastructure.
Gas-based fee model mirrors Ethereum. Prices adjust with congestion. Governance token holders vote on upgrades.
What people actually build
Emerald lets Ethereum developers deploy Solidity without much rewriting. You get DEXes, lending, derivatives, all EVM-compatible.
But the real action is confidential DeFi. Confidential lending hides position sizes and collateral. Confidential AMMs prevent frontrunning by hiding orders until settlement. Confidential exchanges bury order books so MEV bots can't see them.
Hospitals use Oasis to process patient records on-chain while keeping them secret. Financial firms run proprietary trading logic. Supply chains track goods confidentially. ML researchers train models on sensitive data.
Confidential NFTs exist. Private marketplaces for high-value collectors. Portal bridges native assets to Ethereum and Polygon. ML on confidential datasets is possible.
Community and partnerships
Token holders vote on protocol changes. Proposals need minimum ROSE to submit. Discord, Telegram, Reddit host discussions.
The Foundation manages ecosystem development but respects voting autonomy. Grants programs fund projects. UC Berkeley collaborates on research. Binance and other major exchanges listed ROSE.
Security
Intel's Security and Safety Team reviewed SGX implementations. Cryptographers audited threshold crypto and signatures. Trail of Bits and OpenZeppelin examined the runtime and VM.
Side-channel resistance got particular attention—protecting against timing attacks, power analysis, and other TEE-specific exploits. No major incidents since launch.
Vulnerability disclosure works well. The team patches quickly.
Regulatory reality
Privacy tech makes some regulators nervous. Different jurisdictions take different stances. Oasis stayed transparent with regulators and implemented robust KYC/AML at exchange boundaries.
Exchange listings on Binance, Coinbase, Kraken required navigating multiple regulatory regimes. Applications can implement their own compliance if needed.
Hospitals and financial firms need HIPAA, GDPR compliance. Oasis architecture accommodates customizable policies.
Competing approaches
Monero forces all privacy by default through ring signatures. Zcash makes privacy optional. Railgun layers privacy on Ethereum. Optimistic rollups add privacy on top of existing chains.
Oasis uses hardware trust instead of pure cryptography. Different threat models. Emerald's EVM compatibility beats privacy-only platforms that need new development skills.
Enterprises with competitive secrets or medical data are natural fit. Monero suits people who just want money privacy.
What's next
Sub-second finality is in the works. Runtime batching optimizations come later. Throughput improvements aim for more complex confidential computations without lag.
Zero-knowledge proofs and homomorphic encryption get research attention—they could work alongside TEEs. Private cross-chain bridges reduce privacy leakage when moving assets.
New TEE techs (AMD SEV, ARM TrustZone) get evaluated. ML infrastructure for training on sensitive datasets. Post-quantum cryptography for long-term security.
Enterprise tooling: audit capabilities, compliance features, operational support for institutions.
Recent developments
ParaTime optimization continued. New TEE integrations explored. Cross-chain bridges matured.
