Hi,<p>I am wondering if there is scalable cryptocurrency (maybe with smart contracts feature) having typical "blockchain" properties of trust?<p>Best,
Wiktor

IOTA is probably your best bet, although it is still in development.<p>HN loves to hate on it (probably because their funds are elsewhere), but if you read through the whitepapers and the Github I think it is probably the one of the most promising cryptos for actual real-world use.<p>Raiblocks would be my next guess.
