High-performance blockchain projects often confuse throughput with the practical finality of infrastructure.
Speed is merely a measure of how quickly data propagates across a network, whereas finality is the precise moment verification becomes an immutable part of the ledger.
Most Proof of Stake chains rely on probabilistic finality, where the certainty of a transaction only increases as more blocks are added.
Bitcoin requires approximately 60 minutes for six confirmations to ensure a transaction is irreversible, while Ethereum mandates a series of checkpoints that take several minutes to reach economic finality.
Sign Coin utilizes a deterministic consensus model to achieve instant finality within its verification layer.
There is no "wet cement" period where a transaction can be reorganized or dropped, removing the dangerous trade-off between rapid execution and absolute auditability.
Security is not sacrificed for the appearance of scale because every confirmed block is immediately a permanent record.
The protocol has already successfully processed over 10 billion attestations across its global sovereign infrastructure.
