## Intro
Most of it feels like implicit knowledge, but I couldn't find anything written
so here it is. The ideas towards anchor outputs and the conclusions probably
have some new perspectives.
This post is about the game-theoretic security of time-sensitive protocols if

Hi! I and Antoine Riard explored time-dilation attacks on Lightning.
We have a blogpost, which is probably too long to include in the email in full.

There’s also a paper we wrote: https://arxiv.org/abs/2006.01418

Hi,
### Introduction
I was recently looking into AddrMan and I realized that unlike with blocks
(BIP152) and transactions (a node can opt-out via various mechanisms such as
blocks-only or block-only-relay), address relay is under-specified.
For example, we had a discussion [1] on whether SPV n
We are opening for review a draft of the new BIP, which describes low-level
specifications for the reconciliation-based transaction announcement protocol.

Agreeing on this spec would enable integration of more bandwidth-e
Hi all,
We are making public our latest work on Erlay, an efficient transaction relay
protocol for Bitcoin.
It is available here: https://arxiv.org/abs/1905.10518
The main idea is that instead of announcing every transaction to every peer,
announcements are only sent directly over a small numbe
Hi all,
I'm bringing this up again because since the last time (2014) new papers on
network attacks have been published, and in general I think this is
something that has to be done in one or another form.
### Motivation
It has been shown that revealing the topology of the network may increase
the
sync-relay idea has a lot of interesting questions, I’m excited
to follow that research.

Hi all,
I have a couple of ideas regarding transaction relay protocol and wanted to
share it with and probably get some feedback.
I did some emulation and simulation and found out that around 90% of INV
messages sent by public-IP nodes are idle (duplicate), obviously because each
node creates 8
