chinaxcn, Hey mate, can you please ask btc38 staff to increase BTC transaction fee to at least 150-200sat/byte. For some reason they decreased it to 10sat/byte, and now all outgoing TXs are unconfirmed. Have no idea why they did that

Well, I'm stuck now with web wallet
Will community accept one-wallet web storage? I don't consider it secure, because all encryption keys are in my hands.
Multi wallet solution has reached a wall because it requires separate blockchain every time , so ~330MB per user. It does not look reasonable to handle 100 concurrent users for a cost of 32GB of storage, is it? In all other aspects it's fine - each wallet is stored securely with its own encryption key, which I don't know, and after user is done, entire wallet is deleted - it is responsibility of a user to store his private keys in a secure place.
Ideas?
EDIT: Multi blockchain solution seems reasonable only if I introduce service fees, which is not very good.
Hey nice to see a Rubyist here. I'm just a beginner so I can't help much. But don't think that's the optimal solution to have separate blockchain for each user. Can each client share the blockchain of the daemon? The other extreme solution is to translate the client code into native Ruby, but that would be a massive undertaking. |

Looks like they can't - I researched from original bitcoin talk and found out that sharing bitcoin directory can corrupt blockchain. So at cost of ~30GB I can support 100 concurrent users as of now. After timeout, or user leaves the site I delete his wallet(which was previously encrypted). |

So for those just looking at the balance, they can be in the read portion, sharing a blockchain. But for those wanting to make a transaction, they enter a queue to use a dedicated blockchain and get moved off after the transaction. |

Daemon doesn't differentiate between reading and writing - it locks blockchain for its use in entirety. |

Just made a few withdrawals from BTC38, although the daily limit is much less than 50BTC as they promised. truckythin, you can cancel your pending withdrawals by simply clicking on "handling", but it only works in Chinese version of the site. English version is still pretty buggy  |

Coins hang the plant in exchange for 7 hours. Conclusion of BTC was confirmed the day. It is necessary to promote poloniex!

I agree. We should ask them to keep BTC pair, like they did for QRK coin. Users should have a choice what to exchange XCN for. |
