Bitcoin uses Proof-of-Work. This means, BTC is generated and rewarded to the users who provide electricity (mining power) to the Network.
Ethereum 2.0 will use Proof-of-Stake. This means, ETH will be generated and rewarded to users who provide capital (staking power) to the Network.
While electricity (PoW) and capital (PoS) have proven to be respected consensus models, $FLASH uses a more universally finite resource: Proof-of-Time
$FLASH is generated and rewarded to users who provide time (Flash power) to the Network.
The more time committed to the Network, the more confidence can be seen in the protocol; then the interest rate gradually goes down. If confidence reduces (time), the interest rate gradually floats back up. This free-market dynamic will be really interesting to watch in real time, all circling back to the proof-of-time metaphor.
As a Layer 2 asset, the goal of staking $FLASH is not to provide security to the Network. Ethereum does this plenty well.
The goal of staking $FLASH is to fuel the time travel of money. Instead of 1.21 Gigawatts of plutonium powering a 1982 Delorean, users simply need $FLASH to power their flashstake.
