From: Mihail Kostira To: user@cassandra.apache.org Content-Type: text/plain; charset=ISO-8859-1 X-Virus-Checked: Checked by ClamAV on apache.org Hello C* users, I'm contemplating a decentralized protocol whereby data is distributed among several nodes, each node being owned by an independent, potentially malicious entity. The goal is to have the data available, tamper-proof, with no single point of ownership. Also: authorization for data insertion, deletion, and updates is subject to a protocol that binds all nodes. Frequent searches and inserts, rare deletions and updates. Non-refutable timestamps. Would Cassandra lend itself to something like this? Cheers, Mihail
