Introduction

EigenLayer introduces the possibility of re-using ethereum consensus, and IMO the most interesting usecase for that would be building a decentralized two-way and security-optimal bridge between Bitcoin and Ethereum.

All bridges rely on the security of the two chains they connect and the security of the custodian^[1] used for bridging, since if the security of any of those 3 were to fail, it would be possible to drain the bridge (eg: if its possible to double-spend on any of the two chains an attacker can redeem the same coin multiple times).

However, if a significant amount of the total ETH staked were to be restaked securing this bridge, the custodian would be piggybacking on ethereum security, so those two become the same and thus you'd remove the custodian from your list of dependencies and you're left with only having to depend on the security of the two chains, which is the theoretical ceiling of security. In other words, you'd achieve the best possible security.

But not just that, you

If you use server rendering, keep in mind that neither useLayoutEffect nor useEffect can run until the JavaScript is downloaded.

You might see a warning if you try to useLayoutEffect on the server. Here's two common ways to fix it.

Option 1: Convert to useEffect

If this effect isn't important for first render (i.e. if the UI still looks valid before it runs), then useEffect instead.

function MyComponent() {

import { useLayoutEffect, useCallback, useState } from 'react'

export const useRect = (ref) => {
  const [rect, setRect] = useState(getRect(ref ? ref.current : null))

  const handleResize = useCallback(() => {
    if (!ref.current) {
      return
    }

I’ll go step-by-step on how to create a virtual host in the XAMPP environment. As we know, the default http://localhost points to /opt/lampp/htdocs as the root directory. The desired result is to be able to visit http://examplevhost.local, with the root directory being /opt/lampp/htdocs/examplevhost.

Note: The steps below are done on Ubuntu 16.04, but they should also work on most other Linux distributions (Debian, Mint, Arch).

Note: I’ll assume that XAMPP is installed in /opt/lampp/. If it’s different on your setup, please read carefully and adjust accordingly.

Enable virtual hosts in apache configuration file

Note: This should be done only once per XAMPP installation. If you want to add another virtual host later you can skip to the next step.

First of all, please note that token expiration and revoking are two different things.

1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:
