Here’s a whitepaper on the underlying technology:
https://docs.radixdlt.com/alpha/learn/whitepapers/tempo https://docs.radixdlt.com/alpha/learn/whitepapers/tempo
The conclusion in the paper:
“This paper has proposed a method for determining total order of events within a distributed system, without relying on trust, that is scalable, efficient and agnostic to its operating environment. To reduce overhead and increase performance, our solution defines a structured, shardable architecture that limits state transfer information to only members of the network that need it. A peer-to peer network provides the means for communication and information routing via a reliable and robust gossip protocol. Nodes maintain a logical clock when witnessing events and periodically produce a tamper-proof commitment representing those events. When witnessing events, nodes collaborate to create Temporal Proofs which contain verifiable space-time coordinates which are used to construct vector clocks and determine when an event was first seen by the network. Nodes can join and leave the network at will and rely on detectable consistency anomalies to synchronize and bring them up to date.”
The periodically produced commitment log is done with a Merkle tree.
- emXdem 7y ago"verifiable space-time coordinates" no easy task in a world of GPS spoofing and NTP attacks...
- EGreg 7y agoYou don’t need verifiable time-space coordinates. You just need the topology of connections. We came up with largely the same thing two years ago: https://intercoin.org/technology.pdf https://intercoin.org/technology.pdf We call it the Permissionless Timestamping Network and it is one optional component of a cryptocurrency system - but can be used for tons of purposes and is very easy for anyone to join. And since all connections are voluntary, there is no question of overwhelming any nodes either. Pure win :)
