The value of HashPort is not only in reducing storage costs More importantly, it gives websites An On Chain path Container management rights File hashes Readable publishing records A frontend is no longer just code returned by a server It can become an On Chain object that can be read, verified, and managed

A complete DApp should eventually answer two questions Who deployed the contract? Who published the frontend? HashPort is providing the answer to the second question
Traditional model A server publishes a page and users trust it by default HashPort model Files enter a TapeOut Container SiteRegistry records the hashes TapeKit reads and verifies the files
HashPort is not simply copying Web2 websites On Chain It changes how frontends are trusted
HashPort is suitable for uploading HTML, CSS, JavaScript, WASM, configuration files, documents, and lightweight assets
Users should not have to rely only on their own eyes to judge whether a page is authentic A typical website usually tells you This is the official page, trust me HashPort and TapeKit can go further by telling you This file comes from the specified Container and its hash matches the On Chain record

On Chain data is permanent Websites can be updated Secrets cannot be taken back
TapeKit verifies the files when reading them If they match, the files are displayed If they do not match, they are not displayed
A Circuit Container NFT is more than just an NFT It controls the management rights of the corresponding Circuit Container, which also means it controls the right to publish the website Whoever owns the Container NFT has permission to update the website content

HashPort records a SHA 256 hash for every file A hash is a file fingerprint Even if the file content changes by just one byte, the fingerprint will change
Cloudflare users need to set the record to DNS only, shown as a gray cloud
Publishing, storage, and reading each have their own role HashPort publishes the frontend to a TapeOut Container SiteRegistry records the path, size, type, and hash TapeKit reads from BNB Chain and verifies the content The browser displays the content at the end

When connecting a domain to HashPort, you need to configure two records CNAME points to the Gateway TXT proves domain ownership and determines which Container the domain points to
The Operator wallet only has permission to write files It cannot transfer the Circuit NFT or access assets in the main wallet Its private key is stored only in the Session Storage of the current browser tab

Why can Cloudflare Proxy not be enabled? HashPort Gateway needs to read the CNAME and TXT records directly When Proxy is enabled, the DNS resolution path is handled by Cloudflare, which may cause issues with verification and SSL certificate issuance Please use DNS only With the correct configuration, the Gateway can recognize the domain you actually control

What problem does HashPort Operator mode solve? When uploading dozens of files, it would be a terrible experience if every file required a separate signature So HashPort generates a temporary Operator wallet to handle file uploads in batches The main wallet confirms key actions The Operator handles batch uploads

Contracts can be verified Frontends should be verifiable too Put the last layer of trust on chain
HashPort does not verify every type of web resource in exactly the same way The resources that directly affect how a page executes need to be inside the strict verification boundary This includes HTML JavaScript Workers Service Workers WASM Images fonts videos and JSON are not required to be treated as executable resources One of the strictest rules is Same Origin If a page loads executable JavaScript from another Origin, the verifier cannot continue treating the entire page as a fully verifiable frontend Because you cannot verify your own HTML while ignoring the external code that actually executes This is a deeper requirement for onchain frontends Putting a few website files on chain is not the end of the process The important question is which resources actually determine what the user sees and which resources actually determine what the user signs Only when those execution boundaries can be verified does frontend verification become meaningful

The HashPort Gateway is not another trust center A normal browser cannot directly read website files from the blockchain, so a Gateway is needed to read the onchain content and serve it to the browser through HTTP But the Gateway itself does not decide whether a file is authentic After retrieving the file, it should verify the content against the SHA-256 recorded on chain If the returned file does not match the onchain hash, that file should not be treated as a verified frontend This means the Gateway itself can be replaced There can be multiple Gateways, and different teams can operate them The final verification does not depend on any single Gateway It depends on the files stored on chain and the hashes recorded on chain This is an important part of DeWEB Users can access the same onchain frontend through different gateways But the verification result should always come from the same onchain source of truth

Frontend Identity in HashPort is not simply a wallet address It is made up of three parts Chain ID Store Site Chain ID identifies which chain the frontend belongs to Store identifies which Onchain File Store provides the frontend files Site identifies the Site Account associated with those files So the identity of a frontend can be understood as A specific Site Inside a specific Store On a specific chain This is also why HashPort does not use a Domain as the identity of a frontend A Domain is only the entry point used to access a website It does not fully describe the identity of the onchain frontend The combination of Chain ID Store and Site tells the wallet exactly which set of files the current frontend corresponds to on chain Both Hash Verification and Contract Frontend Declaration are built on top of this identity
