My QRL overview here
With there proof of stake draft out I think they will receive a ton of constructive criticism, as well as a jump in price sooner rather than later.
The draft covers there hash-chain authentication aswell as how there POS algorithm is resistant to attacks such as:
Double spend
Successfully spending some money more than once.
Nothing at stake
Explained here
Long range / Hash replay attacks
A network attack in which a valid data transmission is maliciously or fraudulently repeated or delayed.
QRL looks like it is stabilizing around 0.0031 BTC probably a good area to start accumulating. Considering the amount of shit coins out there with a higher market cap than QRL...I think this is starting to become an obvious one.
From there white paper:
"8.1 Proof-of-Stake
QRL is to be an open public blockchain ledger secured by a proof-of-stake algorithm. An epoch lasts for 10,000 blocks. Stake validators are determined from stake transactions in the previous epoch. The general idea is that each stake validator signs a transaction containing the final hash of an iterative chain of length 10,000 hashes (a bitmask XOR may be applied during each iteration to reduce security requirements of the hash function). With the stake transaction confirmed in the chain every node on the network can now tie the cryptographic identity of the stake address to the hash chain for the next epoch ."

That's something that most people don't consider about cryptocurrencies. As soon as quantum computing becomes viable, >99.99% of cryptos as they exist now aren't worth the hard drives that they sit on. I sure hope for steemit's sake they start to implement algorithms that are resistant to that threat in the near future.
in my opinion, ledgers are much better than blockchains
