🤓 Oasis Network Weekly Q&A

General
1

Community is the heart of our project and we’re always looking to answer all questions answered by community members.

We receive a lot of questions on our channels and answers might get lost in discussions, ergo we decided to create a weekly thread here where we’ll cover the most asked questions from our community.

Where do tx fees go? Are they burnt or paid out back to the validators? Is there a way to see the flow?

They are paid to node operators. check non-transaction block events to see the staking transfers from the fee accumulator address. For example https://oasis-findevent.glitch.me/?action=viewStakingEvents&height=11644037 and https://oasis-findevent.glitch.me/?action=viewStakingEvents&height=11644038 (unofficial tool) shows tokens flowing from a transaction sender to fee accumulator, then to the proposer, then in the next block to the next block proposer and signers

How to add the Sapphire paratime on Metamask?

You can add Sapphire mainnet’s RPC to your metamask or simply click the “Click here to register Sapphire Mainnet to your Metamask or Brave Wallet” button on this page :

What dApps can I use on Sapphire at the moment?

Currently there are no third party dApps on Sapphire but some exciting developments are in progress. While we cannot give you more details at the time, we can promise you’ll be amazed.

In the meantime you can try out Wordleish, a Wordle-inspired game written by one of our own engineers, Nick Hynes to demonstrate the value that on-chain confidentiality brings to Web3 gaming.

The game is currently on Sapphire testnet, so you’ll need testnet tokens which you can get here : https://faucet.testnet.oasis.dev/

And you can find the game here : https://wordleish.pages.dev/

These were the most asked questions for this week, tune in next week for more information about Oasis.

The weekly Q&A is here :eyes: :

What’s the difference between OPL and Sapphire?

Sapphire is a groundbreaking developer environment as it is the first and only confidential Ethereum Virtual Machine (EVM) compatible ParaTime. This runtime has the ability to help scale blockchain rapidly towards Web3 and allow EVM developers to quickly lay the foundations for privacy-enabled blockchain dApps, which are becoming a necessity as users demand data sovereignty.

The Oasis Privacy Layer is a gateway to Sapphire’s privacy features for dApps on other EVM chains.

We built Sapphire so that any Solidity developer could have access to privacy and build confidential dApps for Web3. We created the Oasis Privacy Layer so that the hard work already done on other chains with other established dApps can access Sapphire’s unique privacy capabilities without sacrificing anything.

How do I build confidential NFTs on the Oasis network? Are there step by step instructions?

The current simple way is to use https://confidentialtokens.com, but you can use the code at GitHub - oasislabs/parcel-nfts: A DApp that helps creators launch NFTs with truly private data. to create your own NFTs.

If Sapphire has been launched on Mainnet, why are there not dApps to interact with?

We are still working on the supporting infrastructure. Stay tuned for more announcements in this regard.

Do we have any projects in the pipeline for Sapphire? Can we get the list of those as well?

We don’t have an exact list at the moment, but there are a lot of projects looking to launch on Sapphire, including most of the ones that are currently launched on Emerald.

This week’s Q&A is here :eyes:

Q: When is the roadmap for 2023 going to be released ?

A: We have just released our 2023 Roadmap this week, and it’s quite an amazing read. Great things are coming, make sure you check out our blog article : The Oasis 2023 Roadmap

Q: If a project is already developed, will it still be eligible for grant if it will be integrated into Oasis?

A: Absolutely. Our Grants Program is available for both projects that want to launch directly on our network, or established project that want to integrate with our network. You can apply for our Grants Program here:

Oasis Network - Ecosystem

Q: Is there a way in which Oasis can prevent the wallet draining scams?

A: It is impossible to prevent users from giving out their private key or signing transactions that allow an attacker to drain their wallet, as both functions (revealing the key and signing dapp txs) are fundamental.

However, the Oasis community is a good source of information on which dapps are trustworthy and how to maintain a wallet securely.

Q: When is the Privacy Layer launching ?

A: The Oasis Privacy Layer (OPL) is scheduled to launch on Sapphire in early 2023 complete with all the tooling, documentation, and code samples needed to ensure the highest quality experiences for developers and users.

With this technology, unprecedented privacy capabilities will be unlocked for DAOs, on-chain auctions, gaming, decentralized identity, and so much more. To learn more about OPL, visit the Oasis blog here.

Q: Is there a block explorer for Sapphire mainnet ?

A: We will soon launch our new Oasis explorer, which has first-class support for runtimes like Sapphire and Emerald. Robust and versatile explorers are a vital tool for blockchain ecosystems. The Oasis explorer will support all the standard features Web3 natives expect.

Beyond the usual information on blocks, transactions, and assets, the Oasis explorer will also allow users to connect their wallets to access privacy-related features and provide support for contract source verification and parsing transaction data inputs.

Q: I think one of the best applications for Sapphire would be a private bridge to move assets. Is this something that’s considered at the moment ?

A: Consistent with its goal to maximize interoperability with all of Web3, Oasis will lay groundwork for a trustless bridge to the Ethereum and other Layer 1 networks.

The goal is to support a bridge that prioritizes gas efficiency and a trustless, zero-knowledge architecture to accomplish what few other networks have: a simple and secure user experience for moving assets and sending messages from Oasis to another blockchain.

Completing this project first requires some changes to Oasis Merkelized data structures and a Rust implementation of an Ethereum beacon chain client.

Oasis is excited to continue working towards this goal of building a next-generation bridge to Ethereum offering unprecedented efficiency and security.

Weekly Q&A is here :eyes:

Community is the heart of our project and we’re always looking to answer all questions answered by community members.

We receive a lot of questions on our channels and answers might get lost in discussions, ergo we decided to create a weekly thread here where we’ll cover the most asked questions from our community.

Q: If transactions using Sapphire are confidential, what info will be displayed in the explorer?

A: Public transaction metadata will be available to all, and the decrypted transaction data will be available to the one who sent it.

Q: I have some rose in the emerald paratime, how can I transfer it to the sapphire again?

A: Our newest update for the Oasis Chrome extension wallet has been released this week and it allows transfers to the Sapphire Paratime. So the operation would same as for transfering to and from Emerald. First transfer your tokens from Emerald to Consensus, then from Consensus to Sapphire.

Q: Is LaunchGarden a platform supported officially by Oasis Network in the same way as Yuzuswap?

A: Neither is officially supported, but both are popular dapps on our network that we encourage people to do their own research on.

Q: What is a DeFi Aggregator?

A: A DeFi aggregator brings together trades across various decentralized finance platforms (DeFi) into one location, saving users time and increasing efficiency for cryptocurrency trades. As the name suggests, DeFi is spread out across different blockchains such as Ethereum and Oasis Network. Within each blockchain there is an ecosystem of isolated financial protocols.

Q: What is a gas relayer?

A: The Gas Station Network (GSN) is a decentralized network of relayers. It allows you to build dapps where you pay for your users transactions, so they do not need to hold Ether to pay for gas, easing their onboarding process.

Q: What is a trustless bridge?

A: Here is a perfect example of a trustless bridge : Zero-Knowledge Proof Research | Berkeley RDI

Q: Is there a big unlock scheduled? How many tokens will be released on the 18th?

A: Our Token Circulation Schedule is public and you can see the tokens being released here : Token Metrics and Distribution | Oasis Network Documentation

These were the most asked questions for this week, tune in next week for more information about Oasis.

This week’s Q&A is here :eyes:

Q: What are the implications of selecting multiple addresses after the creation of the web wallet?

A: The addresses you select will be available in the account switcher in the top right corner of the page

Q: May someone please explain to me the role of the common pool address and why it executes AddEscrow events to validators?

A: The common pool has the tokens set aside for rewards that are distributed with on-chain logic, which is the staking rewards. To distribute the staking rewards, the network moves tokens from the common pool to validators’ active escrow pools. The network records an escrow add event. When this happens. moving tokens into these pools without creating new shares (note that the new shares field is zero) increases the value of existing delegators’ shares.

Q: Can you please educate me about how OASIS Responsible AI works?

A: Right now, Oasis is working with industry leaders across multiple sectors to design and implement robust primitives for responsible AI. Here are some of the partnerships and developments Oasis is working on:

Through Oasis Labs’ partnership with Meta, Oasis is engineering solutions to fairness and bias in AI models.

Oasis is working with Personal.ai to create pipelines for AI that protects the data shared by individuals for use in developing conversational AI models.

Oasis is developing flexible confidentiality tools for NFTs that shield information tied to an on-chain asset from public view. Data NFT is a token built on Confidential NFT by Oasis that provides access to run computations on data that backs the token, consistent with policies specified by the data owner on data use.

Oasis built the infrastructure for Data DAOs to support individual data rights, reward data owners for data use, handle data with confidentiality and privacy, with verifiable transparency in its operations. This enables data sharing DAOs that can be used for analytics and training of AI models in a decentralized setting.

Q: how long does it take to create a block?

A: Creating a new block on Emerald takes somehwere between 6 and 8 seconds, depending on how congested the network is. You can see more information about blocks here :

https://explorer.emerald.oasis.dev

Q: How do I download all of the last years data from Oasis regarding transactions?

A: You can use this free solution here https://lukaw3d.github.io/oasis-csv-report/

Q: How do I transfer Rose from Emerald to consensus

A: Transfer between Paratimes and Consensus can be done with our Oasis Wallet Browser Extension

Here is a simple tutorial on how to do it :

How to Transfer ROSE into a ParaTime | Oasis Network Documentation

Q: Is the token unlock every three months?

A: You can read more about token metrics and distribution here:

Token Metrics and Distribution | Oasis Network Documentation

Q: Are you accepting new ambassadors?

A: The Ambassador Cohort for Q1/23 is in progress at the moment, so we’re not accepting new ambassadors. A new Cohort session will start at the beginning of April most likely.

Q: What is the APY of ROSE right now? How do you know the current APY % of rose staking?

A: Current APY is 6.028%. You can find out more about Staking Rewards Schedule here :

Token Metrics and Distribution | Oasis Network Documentation

Q: How much ROSE do I need to run a node?

A: Currently, you are going to need:

100 ROSE staked for your entity’s registration since that is the staking thresholds.

100 ROSE staked for your validator node’s registration since that is the staking thresholds.

If you want to be part of the active validator set, you will need enough ROSE staked – this means you will have to be one of the top 120 entities by stake. You can check out current top 120 entities on the blockchain explorer such as Oasis Scan.

This week’s Q&A has arrived :eyes:

Community is the heart of our project and we’re always looking to answer all questions answered by community members.

We receive a lot of questions on our channels and answers might get lost in discussions, ergo we decided to create a weekly thread here where we’ll cover the most asked questions from our community.

Q: Is Parcel a service or a product?

A: Parcel provides a set of privacy-first, data governance APIs designed to give your users better control over how their data is used without sacrificing functionality. Using the Parcel suite of tools will enable you to securely store sensitive data, define and enforce usage policies over data, and share tamper-proof logs of access history with your users.

Parcel also gives you access to Steward, an Oasis Labs web app that makes it easy for your users to manage their data and track usage. You can integrate Steward into your existing user flows, or build your own data management interface on top of Parcel SDK.

Q: What Software for AI is Oasis developing?

A: We have developed the bias measurement system for Meta that uses demographic data from Instagram users in a privacy preserving way to measure bias and hence assess fairness in AI models. We’re also working with Personal.AI to create pipelines for AI that protects the data shared by individuals for use in developing conversational AI models.

Q: Will the events at #BUIDLweek be streamed? Will there be a Q&A session for the community that joined the events online?

A: No there will not be a Q&A session for the online viewers but we will have multiple events in March for the community to participate in Q&A sessions

Q: Does Oasis use ZKPs for privacy ?

A: No, we’re using a secure computing technology called Trusted Execution Environment (TEE). TEEs are used to provide a secure and trusted enviroment for executing smart contracts and processing transactions. By leveraging TEEs, confidential ParaTimes — like Sapphire and Cipher — provide enormous flexibility to developers. Developers can build smart contracts that are fully confidential, fully public, or anywhere in between on that spectrum.

TEEs reduce developer and user friction; a crucial motivating factor for us. The EVM-compatible confidential Sapphire ParaTime functions similar to any other EVM, providing a familiar runtime environment with built-in confidentiality through TEEs.

Q: What’s responsible AI ?

A: Responsible AI is the practice of designing, developing, and deploying AI with good intention to empower employees and businesses, and fairly impact customers and society—allowing companies to engender trust and scale AI with confidence. AI must be developed in a responsible manner, making sure they’re transparent, trustworthy, unbiased, ethical to truly benefit society. And I don’t know if you’re aware, but here at Oasis, this one of our missions, working to resolve the privacy challenges of AI.

This week’s Q&A has arrived :eyes:

Q: Does the Sapphire Mainnet follow the Ethereum Spurious Dragon hard-fork limit of 24k per smart contract?

A: Yes the limit is the same (24k)

Q: Can someone run their own private ParaTime that disables the contract size limit?

A: Anyone can run a ParaTime on the Oasis Network. And yes, a custom Paratime would enable overriding that limit.

Q: Do I need to be whitelisted to run a validator node on Sapphire Testnet?

A: You need to be white listed to run the Sapphire node on the Testnet. Anyone can run the validator node on the Testnet.

Q: Meta recently came up with its AI language… Is Oasis helping them with this ?

A: No. Our work with Meta is around Responsible AI, bias, and fairness assessment.

Q: There are different techniques for ZKP that reduce computational power, will Oasis be using ZKP in the future?

A: There is a lot of research work around ZKP within Prof. Dawn Song’s group and we are always looking at opportunities to bring them to product predicated on demand.

Q: How does TEEs help with scalability?

A: With TEEs and specifically attestations to ensure that a given compute node is running the right code in the expected Trusted Computing Base (TCB), we can reduce the number of nodes that participate in a given computation. This helps scale with a smaller set of nodes to give us runtime integrity. And of course, scale for the Oasis Network is due to the unique separation of consensus from computation enabling purpose built ParaTimes like Sapphire that supports confidentiality with EVM semantics. Furthermore, given TEE based computation runs at near native speed (like running code in a cloud VM), we provide a better security model with virtually no compromise in performance.

These were the most asked questions for this week, tune in next week for more information about Oasis.

This week’s Q&A has arrived :eyes:

Q: What’s the response plan for Andrew Miller’s “spicy printf” bug that leaks access patterns?

A: It is not really a bug, this was well known before and is also mentioned in the documentation. The real solution is having an ORAM library available for use cases that require it (not all do).

You can read more about how we address TEE vulnerabilities in our Blog post

Q: Are there any new projects launching on Sapphire?

A: Yes, there will be a lot of new projects launching on Sapphire and already existing projects have begun their integration with Sapphire. Keep an eye on our channels for announcements in this regard.

Q: What do Decentralized Identifiers do ?

A: Well, they’re a type of identifier (email addresses, usernames are also identifiers) that enables verifiable and decentralized digital identity. DIDs are designed to be globally unique, resolvable with high availability, and cryptographically secured.

Unlike traditional identifiers such as email addresses or usernames, DIDs are not tied to a specific centralized authority, such as a government or corporation. Instead, DIDs are self-owned and can be controlled by the individuals or organizations to whom they belong. This means that DIDs can be used to create digital identities that are more secure, private, and user-centric than traditional identity systems.

Q: How are confidential NFTs different from NFTs?

A: Confidential NFTs operate just like regular NFTs, but also confer access to entirely private data. It is termed entirely private because, unlike traditional NFT unlockables on Pinata, Rarible, and other marketplaces, not even those in control of the network can access the data from confidential NFTs.

They also allow allow creators to mint NFTs that hold data accessible only under certain conditions. Having data-backed NFTs means buyers and holders of these assets are granted something beyond just a receipt — they receive the data, as well as the functionality and possibility that the data can bring.

Only the owner of the NFT can access the additional data tied to the traditional NFT front.

Q: What does Personal.AI do and how is Oasis working with them ?

A: Personal.ai develops AI-based software to help users retain, reinforce, and recall human memory. Oasis is working with them to create pipelines for AI that protects the data shared by individuals for use in developing conversational AI models.

These protections specifically safeguard creators and their online communities so that only with verifiable consented access, can they train AI using an individual’s data. This is what we’re all about, building flexible confidentiality tools that everyone can benefit from. We’re also doing innovations in the confidential NFTs and Data DAOs department.

This week’s Q&A is here :eyes:

Q: In one of the demos from Denver, there was mentioned something about ZK roll ups eliminating the signature step in metamask. Could someone clarify that? What aspect of OPL involves ZK?

A: A ZK bridge or other oracle could eliminate the “Push Vote Weight” step because then Sapphire would just know how many VOTE tokens you have on BSC Testnet(the one used in the demo)

Q: Has Oasis implemented account abstraction?

A: No, but the standard contracts can be deployed on Sapphire with no difficulty. Use Remix, even.

Q: How do I know which places to stake are safe? How do we know that its safe for staking? Do or can any validators just run with your funds?

A: Validators cannot control the delegated funds, you can always unstake (it just takes ~14 days for the debonding period to expire before you get your tokens back). The only way to lose a portion of delegated funds is if the validator gets slashed for misbehavior (e.g. double signing consensus votes, etc.)

Q: What happened to Parcel? Why isn’t it being supported anymore?

A: Parcel is still being supported, it’s currently used as a private internal paratime

Q: Does Oasis have any exposure to SVB ?

A: Oasis Protocol Foundation has no direct exposure to Silvergate or Silicon Valley Bank

Q: Can any EVM get the privacy layer?

A: Yes. we currently support BSC, Avalanche, Polygon, Arbitrum, Optimism, Ethereum, Moonbeam etc.

This week’s Q&A is here and it’s a very comprehensive one :eyes:

Q: What is the smallest amount of Rose 1X10-9?

A: Nano rose (10^-9) on consensus, 10^-18 on emerald and sapphire. be aware that various transactions have separate minimums

Q: How is sapphire privacy related to zksnarks or starks?

A: Sapphire provides confidentiality with EVM semantics so that smart contracts on Sapphire run on-chain using a set of decentralized TEE enabled compute nodes. The advantage is near native performance for smart contracts in addition to confidentiality. Sensitive information can be stored on-chain with encryption supported by a decentralized key manager with the blockchain as the sole root of trust in addition to TEE hardware providers.

ZK techniques are for privacy and scalability where data is processed off-chain and constraints over the processing and the data itself evaluated off-chain with the outcomes of these evaluations available on-chain for verification with proofs of correctness. It is a different scaling technique that also enables selective disclosure of sensitive information for privacy.

Q: It’s about the ledger in parcel, what kind of actions is stored in ledger? The database action? Or any action associated with document.

A: Parcel does not talk to the blockchain and hence does not have any audit logs stored in the ledger.

Q: What are gigashares?

A: In the consensus staking system, entities have escrow “pools” to hold delegations and debonding delegations. pools track different users’ delegations by storing ROSE and a distribution of “shares.” the shares are initially created at 1 share per nano ROSE deposited (and then the ratio changes as the entity earns staking rewards or gets slashed), so the numbers of shares people have are huge. so some explorers display “gigashares” (10^9 shares) so that the number is in the same order of magnitude as the ROSE value of those shares

Q: What is the ‘removeChild’ error?

A: Translation browser extensions alter the web wallet structure in a way that our UI framework can’t handle. It will be fixed in the next update

Q: How can you mint your NFT? Is there any tool to be used on Parcel for this?

A: Parcel supports this feature and this was used for our data backed NFT efforts.

Q: Validators’ commission is deducted from the total amount of tokens, or from the rewards?

A: Comission is deducted from the rewards

Q: How can we connect Oasis Wallet to our frontend application just like metmask window.ethereum?

A: Not ‘just like metamask,’ but use u/oasisprotocol/client-ext-utils. see oasis-sdk/index.js at main · oasisprotocol/oasis-sdk · GitHub for examples. use ‘chrome-extension://ppdadbejkmjnefldpcdjhnkpbjkikoip’ for the origin of the oasis extension wallet

Q: Can one use the same account for both of the wallets?

A: For the web and extension weallets the answer is yes. Other wallets e.g. bitpie and ledger use different derivation schemes

Q: Any news in regards to your collaboration with Meta?

A: Oasis Labs collaboration with Meta is on track and they’ll post updates on this further down the line when they are able to disclose more.

Q: Is Dr. Song still involved in the project and fully dedicated? ( Apparently she is teaching some courses at Berkeley, which is a bit concerning to me )

A: Professor Song is very involved with the project. She has just recently represented Oasis Labs at ETHDenver 2023 (watch her speech here: https://twitter.com/h8sp33ch_/status/1633512921052610561)

Q: Why hasn’t Oasis been able to find any candidates for the open positions? There are about eleven open positions that were posted long ago. on your site. I am just wondering, why haven’t you been able to close those positions after a long period of time.

A: We are always on the lookout for great candidates, especially software engineers and product managers, so we’ll always have those positions open.

We’ve been a bit more picky on the Head of Marketing role but we would really try to close that one soon (if you have a good candidate, please don’t hestitate to contact us)

Q: Any plans to do any sorts of collaboration with AVAX?

A: At the moment, we don’t have any ongoing partnerships or collaborations with Avalanche but we are always open to collaborating with other networks. Oasis Privacy Layer (OPL)is designed to foster cross-chain collaboration by enabling Ethereum-compatible chains to leverage the power of confidentiality provided by Oasis Sapphire.

Q: Also, it is a bit concerning that one address is holding over 2 billions coins

A: The Oasis Networkis a Layer 1 decentralized blockchain network. As others have said, the address you’re seeing is likely one of the exchanges’ cold wallet addresses.

Is this yet to happen, or did you also quit?

19

Mihnea has not quit and is still very much an active member of the Foundation.
