Configure an IP domain with any information that you would like to be cryptographically verified and linked to your registered domains.
Verified Credentials can range anywhere from official social media accounts, access control keys, cards, fobs, badges and even fully customizable and scalable tracked achievements for specific tasks and communities.
Scalable + Composable + Secure blockchain infrastructure that can now be utilized in the most practical and accessible user context.
EBPTO developed the VC.iD to configure domain specific verifiable credentials. VC.iD uses a hybrid architecture with both on-chain and off-chain components. Each domain is issued a VC.iD scope containing a cryptographically signed message. These signed messages are tamper-proof and self-authenticating. This concept is similar to a passport—additional credentials are saved in these passports like stamps.
The VC.iD scope is saved on Ethereum through the EBPTO domain registry. Additional signature data is replicated on Gnosis Chain (xDAI) and IPFS for cost optimization.
The credentials can remain pseudonymous. Individual users can operate multiple domains simultaneously. For example: a real-name domain and a company domain.
Today, most domain products solely focus on resolving complex addresses to readable names using a DNS like interface allowing people to enter anything they like into plain text input fields.
While this free field method is flexible, it does not prevent misinformation (e.g. One could type ElonMusk into a twitter record or Vitalik in the mastodon record).
Verifiable credentials require a signed proof containing information from a valid authenticated session from the issuer (twitter, google, etc).
VC.iD uses the W3C standards for digital, cryptographically verifiable credentials. VC.iD is compatible with EVM (Ethereum) accounts and EVM-based wallet authentication.
From a single domain page you can view the verified credentials of that specific domain. Credentials can be a mix of OpenID based protocols, standard or custom schemas.
![](\"https://docs.ebpto.com/content/images/2022/12/image-1.png\")
A credential can have one or more types. It is specified in an array of strings/URIs. The \"VerifiableCredential\" is mandatory.
The credential type can be used to determine if a specific credential is appropriate for a particular use case. For example, a credential of type \"EthereumAddress\" might be useful to validate a web3 address or specific transaction.
Represents the issuer of the credential. In the case of a social media account verification, the issuer may be the social media network itself, authenticating a session proof.
The credential context contains one or more properties that are related to the context of the verifiable credential.
The context identifier may be an array of subjects (e.g. twitter account credential, followers acount credential, etc).
One or more cryptographic proofs that can be used to verify the authorship of a credential, its context and issuer, ultimately proving the credential is valid.

There are limitless use cases that can be implemented using verifiable credentialed domains. Unlike traditional domains these are stored at the wallet level by their owners outside of the control of any big tech third party.
Domains are stored on-chain in the EBPTO Registry (Ethereum smart contract) leveraging the security, composability, and consistency guarantees.
A manager (registered to an ethereum address) controls the on-chain records associated to each domain.
Credentialed data records are cryptographically signed by the domain manager and stored on L2 (Gnosis Safe formally xDAI) and mirrored to IPFS. The signature of these records is saved on the primary domain itself. This key is called the VC.iD.
Create public profiles with verified social accounts which can be used to create a decentralized identity record. At the highest level authenticate ENS simply by registering a domain. Customize by uploading images and connected verified social accounts.
Blue check as a distributed, verified service.
As we rapidly enter the next era for social and a new way to think about communication within web3—one where users data is portable, and they can take their profile, graph, interactions, and communication wherever they want to; credentialed profiles become key. Credentialed profiles operate as an extended authentication layer providing fully end to end encryption in everything from timelines, social graphs to chats.
Using Public Profiles one could build entire social networks.
Link crypto wallets and annotate activity from many chains, weight, score and roll up into a credit profile.
Complete tasks, learn skills and earn credentials that prove contribution. Build a decentralized school.
Teams can build bridges between its products and users based on verifiable achievements to unlock airdrops, specific rewards and more.
Operate decentralized governance. Create proposals, submit votes and create a sybil resistant governance app. Verified credentials establish non-Sybil traits, preventing capital capture by sybils.
Activities designed to benefit the growth of community can be rewarded to members of a governance model assigning different voting weights to each.
Wrangle wallets to create a transparent audit providing unbiased report of assets held in reserve.
Using the identity protocol (VD.iD) store profile data and gaming data in a way that can be consumed, added to, or extended by any app or game in Web3.
Create a new layer of identity portability across web3. Using the EBPTO issue new domains (.example, .developer) and federate them across the network.

EBPTO conforms to the ENS standard, which means you can integrate EBPTO into your dapp without changing any code. All you need is a Web3 provider that points to the EBPTO registry instead of the ENS registry.
Here is example ethers.js code for creating an EBPTO-enabled provider, looking up an address, and sending 1 ETH to that address:
const provider = ethers.getDefaultProvider({\n name: "homestead",\n chainId: 1,\n ensAddress: '0xDd0Bc20FB93E3033C9282E322f897fC2997F7f92'\n});\n\nconst address = await provider.resolveName("bob.ip")\n\nconst tx = signer.sendTransaction({\n to: address,\n value: ethers.utils.parseEther("1.0")\n});\n\nawait provider.lookupAddress("0xDd0Bc20FB93E3033C9282E322f897fC2997F7f92")\nHere are some key differences between .ip and .eth that you can put to use today.
In order to give users true self-custody over their IP, the associated metadata must be available in a fully decentralized fashion.
We achieve this through our on-chain rendering contract IPTokenRenderer. By contrast, all .eth NFT metadata is mediated by a centralized web2 server (https://metadata.ens.domains/).
Through our IPRegistrationController, EBPTO prevents users from registering names with spaces, zero-width joiners, periods, and other inappropriate characters.
This provides protocol-level security against impersonation attacks. For example: sending eth to JOHN.ip instead of john.ip, or, worse, two names that differ only with respect to the addition of a zero-width joiner (ZWJ) and are visually identical.
By contrast, ENS’s on-chain validation is limited to enforcing only the three character minimum. In practice, ENS’s lack of on-chain validation is mitigated by robust off-chain tooling. However, we believe that when it comes to your IP, users deserve the maximum level of security and authentication.
EBPTO registrations are half the cost of ENS.
On-chain name validation, while more robust, does increase the gas cost of registrations. EBPTO accounts for this enhancement by cutting our registration fees in half, thereby compensating our users for helping to bootstrap the most secure and state of the art system available.
Reduced Fees + Secure Validation.
.eth names must be three or more characters. We have removed this limitation to create even more possibilities.
ENS requires two separate transactions to register a domain, with a one minute “waiting period” between them. This mechanism helps prevent front-running by allowing users to reserve domains for registration before making the identity of those domains public.
However, this approach comes at a cost. Purely in terms of time spent waiting; users have spent in aggregate almost four years waiting to register their ENS domains.
This pause also increases the complexity of client-side registration code. This serves to make registration clients more expensive and complex to create, which increases centralization and hinders utility.
Front running is an Ethereum-wide problem and should be attacked at the network level, not with protocol-specific solutions. Fortunately through Flashbots, any user can create a private transaction that allows them to bypass front-running in registering any EBPTO domain.
We plan on giving users the ability to register using private transactions directly on EBPTO.com.
When you transfer an ENS domain NFT, the previous holder retains the ability to manage the registration. Meaning they can add and remove subdomains, address records, change the avatar, etc.
On the other hand, when you transfer an EBPTO domain, the new owner automatically becomes the owner of the registration record.
We believe this is more intuitive and, most importantly, more secure.

EBPTO is deployed on mainnet at these addresses
First off, thanks to everyone for the huge amount of support and encouragement! We are looking forward to seeing what ways people use their .ip domains.
The EBPTO is a verifiable identity domain registry.
EBPTO aims to make IP portable, memorable, chain agnostic and fun. EBPTO is designed to be decentralized in both it's infrastructure and governance.
What is the goal of the IP Domains?
The most important objective of .ip domains is to become the distributed identity domain protocol standard.
What can I do with my IP domain?
IP domains work on EBPTO's blockchain-based cross-chain registration system that provides a globally unique naming system that can be used in many ways including transferring ETH & NFTs, creating a personalized identity hub, domain name resolution, portfolio management, validated credentials and more.
IP domains are ENS-compatible allowing you to send ETH assets to your assigned .ip domain. (Ex: Send 1 ETH to \"mywallet.ip\")
Resolve addresses with an .ip domain for E2EE messaging, verifiable credentials and more. View the XTMP powered E2EE messaging demo here.
View additional use cases.
What’s the difference between a .ETH ENS domain name and a .IP domain?
An IP domain is an enhanced, Ethereum compatible domain built on the same rails and fundamentals as ENS.
ENS names are human readable with a ‘.eth’ at the end, while IP names are ENS-compatible names that contain ‘.ip' at the end.
Getting an .ip domain does not prevent you from getting an .eth domain from ENS and using it in your Web3 wallet.
In research, we found that most people associate .eth domains solely with Ethereum. We believe you should have maximum control of your IP; that it should be free of limitations. IP domains are designed to be used on multiple blockchain networks.
How are names registered?
Hashes provide a fixed length identifier that can easily be passed around between contracts with fixed overhead.
What are the costs to register ip domain?
Initial registrations are auctioned publicly. Reserve premiums apply for names with 4 characters or less.
5+ characters - $2.50 / year
4 character - $80 / year
3 character - $320 / year
2 character - $640 / year
1 character - $10k / year
Fees are paid in ETH. The ETH/USD exchange rate is set by the Chainlink ETH/USD oracle. Network fees (gas) applies.
How many transactions are required to register an IP domain?
You can register in a single transaction.
Is there anything needed to ensure the continued use of existing IP domains?
Make sure you renew your IP names before they expire. There is a 90 day grace period following expiration.
From the profile view or directly in the smart contract, you can add registration years to any name at any time and extend the registration for as long as you like.
Why do .ip domains use a custom ERC721 base contract (ERC-721PTO)?
ERC-721PTO uses structs to efficiently pack ownership and loyalty metadata information.
Loyalty metadata stored in the ERC-721PTO includes the number of IP domains, initial (minted) registrations, earliest registration period and longest registration period of every active address. The objective is to use this data in a similar fashion as ENS.
\nstruct AddressData {\n uint64 balance;\n uint64 numberMinted;\n uint64 firstRegistrationTimestamp;\n uint64 largestExpiryTimestamp;\n }\nERC-721PTO is deployed with our BaseRegistry contract and can be found here: 0xEB668b89be0C33d1A1559305d75F91e0a54e69Ab
The .ip domain NFT rendering engine defaults to a contract-generated HTML page contanining the registrant, domain name, registration date metadata, and avatar record based presentation. This information is provided in the tokenURI's animation_url param.
Why are there auctions?
Initial registrations are handled through public auctions with a goal to achieve fair access. While names with 4 characters or less are priced in, the auctions are designed to reduce cybersquatting given initial market visibility.
How do the auctions work?
Interested parties can search for a name they have interest in. If the name is not yet in auction, they can activate the auction by meeting or increasing the bid reserve. The bid reserve follows standard pricing guidelines.
Once the initial reserve is met and deposited, the auction lasts 24 hours.
Whenever a new bid is submitted, the prior bid funds are automatically returned and, if less than 15 minutes remain in the auction, the timer is extended 15 minutes. The time extension is an anti-bot mechanism to prevent programmatic sniping.
How Long do I have to settle an auction?
You can settle an auction at any time. When an auction is settled the registration is assigned to the auction winner, who can then claim/settle the auction.
If someone settles an auction on your behalf, only you will receive the .ip domain.
In the event you attempt to settle an auction you've won and the claim button is disabled, it's likely someone has settled the auction on your behalf. Don't worry, no one can take the domain you've won in auction.
Auction Halving
Once the halving begins, at the end of each period the auction length will be reduced by half until auctions are only 1 minute in length. Following the last halving auctions will be disabled and EBPTO will only support open registrations.
24h→12h
12h→6h
etc.
During the halving the 15 minute last bid extension will apply.
Learn more about how open registrations work.
How do renewals work?
Anyone can extend registration years to any existing name by paying the registration fee. You can extend registration at any time.
What is the minimum renewal period?
Renewal duration is recorded in the smart contracts using seconds. While there is no maximum time, there is a minimum period of 28 days.
What if I forget to renew and my domain expires?
There is a 90 day grace period to allow you to extend any registration. After the grace period ends, if not extended you will no longer own the domain.
What happens to the registration & renewal fees?
All fees collected in the registrar contract will be periodically sent to the EBPTO multisig. The multisig roots will determine how to distribute funds across and for the benefit of the protocol. Considerations for fund allocations are largely inspired by ENS, focused on long-term growth, funding DAO, token, external projects that use the protocol and the core EBPTO team.
Where can I manage all my IP names?
Visit www.ebpto.com. Make sure your wallet is connected and click \"Profile\" from the menu. View all of your IP domain names at a glance, or select them individually for details and configurations.
Can I trade or sell my IP names?
You can use the EBPTO Marketplace directly on the site. It allows you to trade IP domains on ebpto.com in addition to other popular secondary marketplaces that support ERC-721, all at once.
When I transfer my IP domains will they still be tied to my public key?No, EBPTO contract clears all registration data including signatures, images and portfolio works when transferring IP domains.
