mev-boost VS next-auth

FYI, this is fixed now: https://github.com/flashbots/mev-boost/issues/541

mev-boost v1.6 was released yesterday - it's often the part of the validator stack that gets neglected when it comes to updates.

For the setup, did you look at https://boost.flashbots.net/ ? Pretty straightforward, and examples of configuration for validator nodes are provided for each soft (prysm, lighthouse, nimbus...). I remember using that (and potentially doing one or two little adjustments). For the explanation, flashbot doc is nice, you can start here: https://docs.flashbots.net/new-to-mev

Are you also using MEV? Because a few people seem to have this same issue. Maybe it is a MEV-Geth thing. If so could you post your MEV logs?

Ahh I see yep, on the builder side not the validator side. Validators using https://github.com/flashbots/mev-boost but whichever builder gets chosen may likely be using those (especially if flashbots has the highest bid).

Personally I think the risk benefit is better to have mevboost activated. https://github.com/flashbots/mev-boost/issues/518

The same thing happened to me, I opened an issue in prysm and in mevboost, we are not the only ones with bad luck, https://github.com/prysmaticlabs/prysm/issues/12434 https://github.com/flashbots/mev-boost/issues/516 try adding the --build-block-parallel flag I also removed 2 relays, flashboot and brute. Hopefully next time we'll have better luck. sorry for my bad english

MEV-Boost is an implementation of proposer-builder separation (PBS) built by Flashbots for proof of stake Ethereum. Validators running MEV-Boost maximize their staking reward by selling blockspace to an open market of builders.

NextAuth.js is not perfect. One of the shortcomings is that it currently does not implement federated logout. This means that even if a user signs out of the Next.js app, he does NOT get signed out of the Cognito user pool client. As a consequence, the user is not really being logged out (i.e he is able to login again without providing the credentials). You can read more about this problem in this Github thread.

NextAuth for adding auth

Let's learn a bit about Descope and how to use it with Auth.js (next-auth) to protect our Next.js app with role-based access control (RBAC).

Next Auth CognitoProvider Internal Library: https://github.com/nextauthjs/next-auth/blob/v4/packages/next-auth/src/providers/cognito.ts

I mentioned this in an age-old discussion on NextAuth GitHub repo.

Authentication is a fundamental part of most web applications. Integrating authentication into your Next.js app can be simplified with NextAuth, a powerful authentication library that supports various authentication methods. However, the documentation around setting up NextAuth with the "Credentials" auth provider might not be as clear as you'd hope. My implementation is greatly enriched and partially based on Next-Auth docs and the following github thread.

For Auth: https://authjs.dev/ - works like a charm with Svelte https://authjs.dev/reference/sveltekit

NextAuth.js

I'm surprised nobody mentioned https://authjs.dev/
