Fingerprinting nodes: Possible Solutions

3+ hour, 47+ min ago  (769+ words) Tldr: Nodes that are reachable over multiple networks (e. g. , IPv4 and Tor) can be fingerprinted by comparing ADDR responses across different connections. A correlation between addresses is created and further strengthened using shared timestamps. Since the previous post, we've eliminated some solutions…...

[Proposal] Public Fraud Proofs for Just-in-Time Channels

5+ day, 12+ hour ago  (184+ words) Hello everyone, I have long been unsatisfied by the trust model of just-in-time channels. Here is a new proposal, that attempts to improve the situation using fraud proofs and game theory. The main idea is that clients should publish the…...

SHRIMPS: 2. 5 KB post-quantum signatures across multiple stateful devices

4+ week, 2+ day ago  (242+ words) A signing device is initialized by loading the seed, which deterministically derives both SPHINCS+ key pairs. To sign, the device looks up its persistent state for this key to determine whether it has signed before: if not, it signs through…...

Propagation Delay and Mining Centralization: Modeling Stale Rates

5+ mon, 1+ week ago  (133+ words) Average revenue isn't the right model, the reality is much worse" much of that $91m will go to power costs, right? So the miner's net profits is increased by a much larger factor. The actual impact on the network is hard…...

Path Queries: Addressing Payment Reliability and Routing limitations

11+ mon, 3+ week ago  (89+ words) Introduction To route a payment on the Lightning Network, a sender must choose a path to the destination using channels which contain sufficient liquidity and meet certain forwarding rules (e. g routing fees). As neither the liquidity nor the balance in…...
