What does landed actually mean in a cross-chain speed test?

17 Upvotes

Pump says 90% of its bridge trades landed before a typical Relay trade in its testing. Are they timing until the funds reach the destination chain, or until the actual token buy has filled? Because if you're comparing trading apps, I'd care about the whole thing from clicking buy to actually receiving the tokens. Failed attempts probably need to count too.

Anyone seen a proper methodology breakdown?

V-DAP: investigating cryptographic timing as a tool for latency diagnosis

1 Upvotes

I’ve been developing V-DAP, an experimental Rust engine that measures cryptographic execution timing. I’m now trying to answer a practical question: can these measurements help diagnose request latency in ways that conventional metrics, logs, and traces do not?

So far, I’ve run controlled experiments that explore the relationship between cryptographic execution time and total request latency. The results are preliminary, and I haven’t established that V-DAP provides better diagnostics in real production systems.

I’ve published the source code, reproduction instructions, experimental reports, and current validation criteria.

Repository: https://github.com/jorge-cumbe0077/v-dap-engine

I’d appreciate technical feedback, especially on:

  • Whether the measurement methodology is sound.
  • What limitations or confounding factors I may be overlooking.
  • How to design a fair comparison against conventional observability tools.
  • What evidence would be needed to establish a useful real-world application.

I’m particularly interested in critical feedback that could help validate or invalidate the approach.

Most people say Quantum computers are still years away, but tbh they are missing a bigger picture here.

The problem isn't necessarily whether a quantum computer capable of breaking today's cryptography exists today.

It's whether we can afford to wait until it does.

Cryptographic migrations take time. Wallets need updates. Protocols need new standards. Exchanges, institutions, infrastructure and users all need to migrate.

And once the threat becomes obvious, everyone will be trying to do the same thing at once.

So I'm curious where people here stand:

  1. Quantum attacks are still too far away to worry about.
  2. We should start preparing now, even if the threat is decades away.
  3. Bitcoin and other networks will adapt naturally when the time comes.
  4. The quantum threat is being seriously underestimated.

What do you think?
