PoAge Is Trustless
Canopy's Proof-of-Age
Canopy introduces a unique mechanism to allow trustless syncing of the blockchain:
💡 Verifiable-Delay-Functions are a cryptographic primitive that requires the execution of sequential work that is fundamentally resistant to hardware speedups.
In other words...
👉 VDFs are a reliable proxy for elapsed time
This enables Canopy to reliably utilizes a fork-choice rule of the oldest (age) chain
— allowing a syncing node strong subjectivity when choosing between two forks.
TL;DR: Like PoW — Proof-of-Age enables trustless syncing, but without the energy costs!
The Result: NestBFT
NestBFT uses Proof-of-Stake for:
Energy efficient consensus
Simple and self-reinforcing 'sybil attack' protection
Instant finality with 20 second blocks
Economic stability via bonding
... and Proof-of-Age for:
Verifiable mitigation of Long-Range-Attacks
An additional layer of security against emerging threats
Extending security to Nested Chains by offering decentralized Checkpointing-As-A-Service
The combination of the two ensures NestBFT is fundamentally more trustless than legacy PoS systems.
Since trust is involved with Ethereum's Gasper and Tendermint's BFT — how much of Web3 is truly trustless?
