Names, Not Numbers:

A look at blockchain naming services such as Ethereum Name Service (ENS) and Cellula ID, and the role they are starting to play in everyday crypto payments, post-quantum security, and payments made by artificial intelligence (AI) agents. September 2026 Summary The problem is the address. Crypto wallet addresses run from about 42 to nearly 100 characters of random-looking text. One wrong character, or one lookalike address pasted from a scammer, can send funds somewhere they can never be recovered. Naming services fix the interface, not the money. A name such as maria.cell or maria.eth points to a real wallet address. The payer types the name, the wallet looks up the address on the blockchain, and the payment goes directly to the recipient. Costs have come down to the level of a coffee. A standard name costs about $5 a year on both ENS and Cellula.ID. Short, premium names are where prices differ most. Cellula's 4-character names cost $20 a year compared with $160 on ENS. Names are turning into payment identities. A single Cellula.ID name can receive CKB, Bitcoin, and Ethereum payments and can also serve as a Bitcoin Lightning Address, a personal web page, and a signed payment request link. Security is looking further ahead. Cellula.ID lets owners hold a name under a post-quantum lock based on SPHINCS+, the design behind the United States government's new hash-based signature standard. AI agents need names too. Software agents are already making tens of millions of small payments a month. Readable, verifiable names give people a way to see and control where an agent sends money. 1. The weakest link in crypto is a string of characters Ask most crypto users what makes them nervous about sending a payment, and the answer is rarely the blockchain itself. It is the moment right before they press "Send," when they are looking at something like this: ckb1qzda0cr08m85hc8jlnfp3zer7xulejywt49kt2rr0vthywaa50xwsq... Nobody can read that out loud, remember it, or confidently…
