VeriCoin Launched: May 10th Midnight EST, PoW Ended May 17th 2014, PoS only
Launched in May of 2014, VeriCoin is a Proof-of-Stake-Time currency with a disinflation targeted interest rate which is dependent on the degree of staking. Stake-Time is a new proof that favors both number the number of coins held and how often they are staked. Together these features make VeriCoin top in security and incentive.

Variable block time:
It automatically addresses the scalability issue BTC has.
It increases blockchain performance with security.
It softens the difficulty mechanism without loss of security, so that mining power can grow more efficiently and organically.
Rewards in minutes per mining between blocks enables more profitability of mining that is dependent on power and time burning electric.
A decreasing reward as the blockchain speeds, incentivizes a balance of efficiency and power, while reducing new supply based on demand.
ASIC and GPU inefficient and resistant due to memory latency.
So as a standalone PoW it will be one of the best and most innovative approaches to PoW.
