Hi all,

Since I'm newbie I need to create several posts on this forum, so here is mine)
I've noticed that all known (to me) cryptocurrencies are strore full transaction history for every available "coin". So, is to store this history really necessary? A simple alt. way may be just to store current balances of every user. Actually it even seems to enough to strore one-way accumulator hash of all balances and send required for every node hash update when new block is generated.

If you can figure out how to do it without needing a blockchain, you'll have the only decentralized cryptocurrency in the world that doesn't require mining.

A solution in my signature.

You are talking about completely different cryptocurrency security model (and probably far not as secure as btc). But my question are there some bitcoin-like currencies (based on blockchains) that are not store transaction history. I described how it could be done and would like to see some critics or links to such altcoins.
