Title: howto share .bitcoin/blocks directory Post by: Zz on October 23, 2016, 08:40:04 PM Hello,
We use the same computer 3 people 3 shell accounts; user1@kutaypc : /home/user1/.bitcoin user2@kutaypc : /home/user2/.bitcoin user3@kutaypc : /home/user1/.bitcoin we have jointly directory ~/.bitcoin/blocks our setup : add bitcoiners group users add bitcoiners group mkdir /home/blocks chown root:bitcoiners /usr/bin/bitcoind chown root:bitcoiners /usr/bin/bitcoin-qt ln -fs /home/blocks /root/.bitcoin/blocks run bitcoind -daemon control debug.log bitcoind is fine! and switch user1 echo "listen=0" > /home/user1/.bitcoin/bitcoin.conf and run second bitcoind at user1 account. works fine. stop bitcoind rm -rf /home/user1/.bitcoin/blocks ln -fs /home/blocks /home/user1/blocks newgrp bticoiners (switch to bitcoiners group) and run second bitcoind at user1 account. program crashed! any solutions ?

They will run into simultaneous write issues and corrupt the data on the disk.

Well, exchanges or web wallets are how it works? new setup: create 3 bitcoin adress on one bitcoind (run as root) works fine but only one rpc user?? I need 3 rpc user? if I can create 3 rpc users for 3 bitcoin adresses, users runs bitcoin-cli Title: Re: howto share .bitcoin/blocks directory Post by: achow101 on October 23, 2016, 09:09:59 PM new setup: You only need one rpc user. However, you should not do this. Bitcoin sent from one address will end up in a change address. Bitcoin Core does not know that the three addresses are meant for three separate users. It thinks that they are all part of the same wallet (because they are) and treat them as such. Thus you will end up with one user accidentally spending the Bitcoin of another user. The only way around this is to use raw transactions and that can be a dangerous if you don't know what you are doing.create 3 bitcoin adress on one bitcoind (run as root) works fine but only one rpc user??

They will run into simultaneous write issues and corrupt the data on the disk. Wouldn't that not be a problem in this case because OP said 3 accounts on the same computer, and to switch accounts, you need to log off, closing all running programs. Bitcoin Core would never be writing at the same time with other instances, so nothing would be corrupted.Title: Re: howto share .bitcoin/blocks directory Post by: achow101 on October 23, 2016, 09:57:28 PM Multiple instances of Bitcoin Core on the same computer cannot share the same blocks (or data directory) folder.
