On BNR: EOS and open source

Radio discussion of blockchain choices, open source and content proof.

What was discussed

A comparison of blockchain architectures for content applications, why proof-of-work chains were a poor fit for per-article timestamping, and what open source means when the infrastructure underneath you is itself open source.

The technical thread

Timestamps need many small writes with predictable cost. That constrains the choice of chain far more than any marketing comparison does. See the reasoning in full.

The open source thread

If the application is open source but the infrastructure it depends on is not, you have moved the lock-in rather than removed it. See open source.
