   FWIW, it is already possible to use the V8 bytecode equivalent of your code for the SEA. Here's a step by step demo (on macOS):

   # The code you want to obfuscate by translating to V8 bytecode.
   $ echo 'console.log(`Hello, ${process.argv[2]}`);' > hello.js
   
   # Installing the dependencies.
   $ npm init --yes && npm i --save-dev bytenode esbuild postject
   
   # Creating a standalone JS file that uses the V8 bytecode of your original application.
   $ node_modules/.bin/bytenode --compile hello.js
   $ echo "require('bytenode').runBytecode(Buffer.from('$(base64 -i hello.jsc)', 'base64'))()" > input.js
   $ node_modules/.bin/esbuild input.js --bundle --platform=node --external:electron > bundle.js
   
   # Building the SEA.
   $ echo '{ "main": "bundle.js", "output": "sea-prep.blob" }' > sea-config.json
   $ node --experimental-sea-config sea-config.json
   $ cp $(command -v node) hello
   $ node_modules/.bin/postject hello NODE_SEA_BLOB sea-prep.blob \
       --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 \
       --macho-segment-name NODE_SEA
   
   # Running it.
   $ ./hello world
   Hello, world

   This will just work as hello.js contains no require. As soon the code gets a require like "const http = require('http');", it breaks..
   Any idea?

   The error message is this

   `evalmachine.:1
   "​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​"

   any solution for this? :)

   Here someone said we need to do this:
   const bytenode = require('bytenode');
   const result = require("./path/to/compiled.jsc");
   console.log(result)
   bytenode/bytenode#236 (comment)

   but the problem is that with sea the require to the compiled.jsc will not work
