Why Satoshi Did Not Want to Put the Whole World in One Chain
In 2010, forum participants discussed decentralized name registration. The obvious route—adding another data type to Bitcoin—looked to Satoshi like a poor way to scale.
EDITORIAL OVERVIEW · Prepared by the project editors from the sources listed below.
The BitDNS problem
The proposal aimed to register and transfer domain names without a single registrar. Its mechanics resembled Bitcoin, but its rules and data served a different purpose.
The discussion considered putting names in Bitcoin, creating a common parent chain, or launching a separate network. One chain appeared stronger because it would avoid dividing miners' computing power.
Satoshi's answer
Satoshi proposed separate networks and separate blockchains that could reuse the same proof of work. A miner could work for both systems, while a Bitcoin user would not need to download BitDNS data and a BitDNS user would not need Bitcoin's full dataset.
He warned that piling every proof-of-work system into one dataset would not scale. Networks needed separate fates: one community might accept large data features, while another might tightly limit its chain so ordinary users and small devices could still run full nodes.
The idea that outlived the name
The exchange anticipated the principle of merged mining: separate chains keep their own rules while sharing computational security. A similar approach soon became part of Namecoin's history.
The broader lesson is that decentralization does not require placing every useful record in Bitcoin. Sometimes resilience comes from separation: shared security work, but different data, users, and consequences.
Shared computational security does not require a shared database.

This is a historical summary of the BitDNS discussion. It explains Satoshi's position in that context, not a universal prohibition on every form of additional Bitcoin data.
