Creating a global specialized identification system (such as a decentralized naming and identity layer using extensions like ⁠.glb⁠) offers profound structural upgrades over legacy infrastructure, but it also invites severe operational and systemic friction.

The Pros

 True User-Sovereignty and Censorship Resistance: Identity assets and sub-namespaces are owned directly via cryptographic keys (NFTs or self-sovereign accounts). No centralized corporate registrar, cloud provider, or government agency can arbitrarily seize, freeze, or reassign a name like ⁠company.glb⁠ without the private key holder’s signature.

 Universal Multi-Chain Portability: Unlike traditional Web2 handles or platform-specific usernames (which trap users inside siloed apps), a decentralized global ID acts as a single cryptographic passport. It simultaneously routes payments across multiple blockchains, maps to decentralized storage, and handles W3C verifiable credentials.

 Elimination of Intermediary Rent-Seeking: By removing traditional top-level domain brokers and commercial middlemen, registrants interact directly with smart contract code. This creates transparent, predictable lifecycle costs and automated ownership transfers without administrative markup.

 Granular Sub-Namespace Control: Owners of a root identifier can dynamically provision sub-identities (e.g., ⁠pay.company.glb⁠ or ⁠auth.company.glb⁠) under completely programmable permission structures, giving enterprises and individuals absolute architectural control over their digital footprint.

The Cons

 The Mainstream Resolution Barrier: Traditional web browsers (Chrome, Safari, Edge) and default operating system DNS resolvers do not natively parse alternative blockchain roots or non-ICANN namespaces. Users are typically forced to install custom browser extensions, configure manual RPC profiles, or use niche gateways—introducing a massive UX bottleneck that halts mass adoption.  

 The “Cold Start” and Integration Deficit: Third-party applications, backend enterprise databases, and standard software packages often enforce strict regex string validation expecting standard Web2 formats (like ⁠.com⁠ or ⁠.org⁠). Overcoming this requires continuous, expensive lobbying and technical integration work across thousands of independent software ecosystems.

 High-Stakes Legal and Regulatory Collisions:Operating outside the traditional ICANN root zone does not exempt a project from national laws. Global trademark offices, anti-cybersquatting laws (such as the ACPA), and consumer protection frameworks can still target individuals or entities controlling specific on-chain identifiers if they clash with established corporate brands. Furthermore, parallel namespace expansion by traditional authorities (such as ICANN’s gTLD application rounds) creates constant collision risks where traditional domains overlap with on-chain assets.  

 Permanence and Human Error: On-chain finality means that a lost private key or an irreversible transaction error permanently locks an entity out of its global identifier, with no “forgot password” button or customer support desk to reverse the damage.
