what is Polyhedra?

Polyhedra is a project where you can transfer your assets between networks and share data between web2 and web3 systems. You can also send direct messages onchain with your wallet through different blockchains, and it works just like internet emails.

Polyhedra uses advanced zero-knowledge proof (ZKP) technology for its capability of providing high security, scalability, and privacy and aims to provide a reliable platform for asset transfer, onchain massaging, and in total, a web3 infrastructure that users can enjoy and benefit from.

Polyhedra insists on three main factors: interoperability, scalability, and fine-grained privacy.

Interoperability :

Polyhedra guarantee high-level security without extra trust assumptions just by implementing infrastructures for Web3 interoperability across different systems.

Scalability :

With distributed computing networks, polyhedra designs and develops scalable and efficient zero knowledge proof protocols for large scale zkp systems.

Fine-grained privacy :

Polyhedra Network provides fine-grained privacy extensions for Web3 with stealth address models, meeting both privacy-preserving needs and compliance policies.

Products

There are three main products in polyhedra for now, ZkBridge, ZK-DID, ZK-NFT.

ZkBridge :

zkBridge uses zkSNARKs to enable a prover to efficiently convince the receiver chain that a certain state transition happened on the sender chain. zkBridge consists of a block header relay network and an updater contract.

The block header relay network retrieves the block headers from the sender chain, generates proofs of the validity of the block headers, and sends the headers along with the proofs to the updater contract (set up on the receiver chain).

The updater contract maintains a light-client state. It automatically adds block headers to the sender chain once the associated proofs are verified and updates the current main chain of the sender chain.

ZK-DID :

The ZK-DID is a verifiable credential system that is secure, interoperable, scalable, and easy-to-use. Users' privacy is protected with advanced zero-knowledge-proof technologies that can be used for both Web2 and Web3 purposes.

ZK-NFT :

The ZK-NFT container is a new NFT protocol that can contain other NFTs, realizing maximum interoperability. The container pointer is further encrypted with zero-knowledge proofs to protect the privacy of related assets.

Tutorial

intro

we can use polyhedra for creating/transferring NFTs and also onchain massaging. you can test it first on testnet then you can use it on mainnet, for now there are BSC and ETH available on mainnet and you can transfer your NFT to EVM chains like Avalanche and Polygon.

NFT minting

First, you can use their faucet NFT and mint one through this link, or you can create your own NFT. For minting from the faucet, just select your desired blockchain (BNB or ETH for now) and press the request button. A pop-up will appear, and all you need to do is confirm it.

For minting your own NFT, head to the main page, tap the circle beside your address in the top right corner, and choose "Create an NFT.

You can drop or browse your image, then pick a name for your NFT, write a description, add properties to customize your work, select your desired network, type of contract, and number of supplies, then hit the create button and enjoy your new borned collection.

Bridge

Now that you have your NFT, you can bridge it to other chains with a satisfying number of options to choose from. From the faucet page, after a successful minting, you can use the zkbridge button, as you can see on the NFT faucet 3 image, and it will import your recently minted NFT data automatically, or you can transfer it through this link and fill in the desired data manually, such as the smart contract and token ID.

Select the sender and receiver blockchains and the recipient address, which is by default your address.

Now you have to confirm two transactions: one to approve spending the NFT, and the second to execute the transaction.

After those two transactions are successfully initiated, you can claim your NFT on the destination blockchain.

Well done.

If you are receiving NFTs from another address, you have to paste in the sender transaction hash (from Step 3) to resume your transfer.

messenger

Sending on-chain messages via polyhedra is so simple and fun. All you have to do is head to the Messenger page, write your message, choose the sender and receiver networks and addresses, and hit the "Send a Message" button to initiate the transaction.

And that’s it. It's a very useful project, as you can see. So why not give it a try? And remember, have FUN.
