Vendor Diversity:

6 unique cloud providers (AWS, Azure, Hetzner, DigitalOcean, Vultr, Linode) ensure no single vendor outage can compromise the network.

Why RedPanda + PostgreSQL

We selected RedPanda and PostgreSQL for several critical reasons:

  • RedPanda: Kafka-compatible but with zero JVM dependency, lower latency, and simpler operations. No Zookeeper needed.
  • PostgreSQL: Battle-tested, widely deployed, excellent tooling. No vendor lock-in or complex licensing.
  • Operational Simplicity: Easier to operate across 20 distributed SCN validators with diverse operators.

Consensus Parameters

CometBFT consensus with 14-of-20 signing threshold and 1.5-second block time.

Parameter Value Description
Consensus AlgorithmCometBFT (Tendermint)Byzantine fault-tolerant consensus
Total SCN Validators20Fixed SCN validator set
Signing Threshold14-of-20 (70%)Required for block finality
Byzantine Tolerance6 SCN validatorsMax faulty SCN validators tolerated
Block Time1.5 secondsTarget block interval
Max Block Size10 MBMaximum transactions per block
Max Transactions10,000/blockTransaction throughput limit
Double Sign Slash5%Stake slashed for equivocation
Downtime Slash1%Stake slashed for extended downtime
Geographic & Vendor Resilience

No single region, jurisdiction, or cloud vendor can block consensus or compromise the network.

Regional Distribution

Region SCN Validators % of Network Can Block Consensus?
Europe (CH, UK, DE)420%No (need 7+ to block)
Asia-Pacific (SG, JP, AU, PH, IN)735%No (need 7+ to block)
Middle East (UAE)210%No
North America (US, CA)315%No
South America (BR)210%No
Africa (ZA)210%No

Cloud Vendor Distribution

Vendor SCN Validators % of Network Single Vendor Failure Impact
Hetzner840%Network continues (12 remaining)
AWS Amazon Web Services630%Network continues (14 remaining = threshold)
Azure Microsoft315%Network continues (17 remaining)
Others (DO, Vultr, Linode)315%Distributed across 3 vendors
Key Resilience Properties:

  • No single jurisdiction controls >2 SCN validators (max 10%)
  • No single continent controls >7 SCN validators (max 35%)
  • 8 different cloud vendors prevent single-vendor failure
  • Network survives loss of any 6 SCN validators (BFT guarantee)
  • Combined US+EU shutdown leaves 12 SCN validators operational
