It's sad that respected developers arm these newbies with irrelevant half-truths and these newbies go spread those on the forums. In the end, they lose, because they start believing these now irrelevant half-truths and miss out on good investments.


Oh well, what do you think are the criteria for them to be considered secure by you, personally? How long should this or that PoS implementation be around to prove it's secure?

Nothing is 'secure' except relative to a threat model.  When people say PoS is insecure, as best I can tell, they mean their personal threat model defeats PoS.

PoS vulnerability does not strictly depend on an arational/irrational actor because of replays rolling back to before a liquidation of stake.

Are charts allowed in here?

I'd like to point out a huge opportunity i see in CRYPTCOIN. As you'll see in the charts below:

- Prices are down 10X from where they were less than a month ago
- Volume is starting to pick up again and we've had a solid breakout yesterday
- Orderbook is stacked heavily to the buy side

1 MONTH




1 WEEK




ORDERBOOK



Some info on CRYPT:
11 Million Coins Total, 3 Million in Circulation (Very Rare Coin!)
X11 algorithm (CPU & GPU mineable)
Block Time: 1.5 Minutes, 2.75% PoS interest annually
Current Block Reward: 31 CRYPT
Current Market Cap: $600,000

Anon feature without using master nodes is also in development

For now sure, but looking at the charts we have an obvious breakout after a steep selloff. We can either ignore or accept the technical signals that are pointing to the upside.

lol, ill be back here when the price has doubled (with pics)  


ps. the devs are still very active- https://bt.irlbtc.com/view/618377.0

pss. read the whitepaper- http://cryptco.org/Cryptcoin-CryptCast-Anonymous-Whitepaper.pdf

Yes, they could've just as well used these bullet points instead (source):

• Coin Age will no longer be a factor to generate Proof-of-Stake interest. There is a need for more nodes online and staking. More staking nodes will also speed up the BlackCoin network and transaction time. Do keep in mind the staking rewards are not affected by this change.
• The stake modifier will be changed at every modifier interval
• Further blockchain timestamp changes will be made to avoid Proof-of-Stake blocks from orphaning.
• BlackCoin will no longer be using the Scrypt algorithm for its Proof-of-Stake phase, and will revert back to SHA-256D. Using Scrypt offers no real advantages , and is in fact slower compared to some of the other alternatives.

Here is another good example of an attack against a PoS only coin: https://bt.irlbtc.com/view/679791.msg7848188#msg7848188

To make it short they did a doublespend attack on a private fork and then unleashed it to the network, resulting in bittrex losing bitcoins.

The real problem is see with this is, if due to those attack the exchanges get bankrupt it will hurt a lot of innocent people who were just trading their coins there and thats bad for crypto in general...


Peercoin/Novacoin doent have this problem, as they are using the pow blocks to generate the pos hashes:
https://bt.irlbtc.com/view/131940.0
and added centralized auto-checkpointing to it to secure it further (tho their system is still gameable, just harder).

Why do you say Peercoin isnt relevant? Its still the pos coin with the highest marketcap which is forked from bitcoin.

I dont see CRYPT as a shit pump n dump clone (I believe we are seeing movement here because of fundamental reasons). This is a 2.0 gen x11 pow/pos anon coin trying to compete with DRK. I really think it has long term potential in terms of having a unique mixing algo - http://cryptco.org/Cryptcoin-CryptCast-Anonymous-Whitepaper.pdf.

cheers everybody

Their github has not a single update since launch, if thats what you call real development i cant help you.
