Blink – Scalability with Sub-second Latency
summary
Blink claims a payments-optimized DLT that uses a mini-chain per account and requires each transaction to reference a past global state (two timed rounds) so unrelated transactions run in parallel; guardianship is a proof-of-stake locker scheme where lockers sign and earn most fees and can rate-limit spam. A live AWS demo on 16-core/64GB VMs shows ~130 TPS steady, ~200 ms locker confirmation, 470-byte transactions (~11 MB/s network), and CPU bottlenecks when pushed toward 5,000 TPS causing round finality to slow.
