Episode notes
Blockchain Needs Custom Networks
- Blockchain needs its own purpose-built, high-performance network to scale efficiently.
- Existing internet routing and networks don't meet blockchain's low latency and high throughput needs.
Bandwidth Is Blockchain Bottleneck
- Compute is no longer blockchain's bottleneck; bandwidth is the real limitation.
- Testnets can show high TPS because they run in controlled environments unlike mainnets.
Single ASN Boosts Routing Efficiency
- Routing traffic on a single ASN makes blockchain network routing more efficient.
- Double Zero achieves this decentralized multi-node peered network unlike traditional internet routing.
