fslkjhjdfhgj4j··on Show HN: A Browser-based Blockchain
Left this running all day at about 30kh/s and got 200 coins

Couple of hints:

* Have a way of backing up your private keys! Many people delete browser local storage and this is not a safe or long term place for them to live! NAG THE USER TO DO THIS. 99% of the people here betanet will lose their keys, fo sure

* Consider hierarchical deterministic (HD) generated keys, so a single seed can generate all future keys

* Consider brainwallet seed (must be long, suggest at least 256 bits entropy), custom dictionary words

Most cryptocurrencies use secp256k1 or ed25519 for ecdsa/xeddsa as their curve, this is using P-256. Satoshi was suspicious of the NIST curves, thats why he didn't use P-256 for bitcoin.

You will need something better than SHA256 for PoW function too, others have identified memory hard hash as idea. Look at Momentum (ProtoShares), EtHash (Ethereum) and CryptoNight (Bytecoin/Monero) as approaches to this. All have rolled their own in this space, keep you tx hashes standard but use something creative for PoW function.

Please promise to either host it forever or give it to the internet archive when you are done. This could be a nice cultural catalog of humanity.
