Sepolia is now on PoS

As of 2022/7/6, Sepolia has switched to PoS. The window to do some mining has closed.

Testnets after merge (original, old content from here)

It's mid 2022, Ethereum is still PoW and motoring towards merge / PoS. Surviving testnets will be Sepolia - currently PoW - and Goerli. Ropsten will be merged and then deprecated, Rinkeby and Kovan won't be merged.

I want to "get ready" for some Sepolia testing pre- and post-merge. Sepolia will not have a public validator set; testing post-merge will be limited to running applications on it. As Sepolia is PoW, I can actually go mine myself some SepplETH. Here's how.

Writing an apt proxy conf file /etc/apt/apt.conf.d/proxy.conf as below.

Acquire::http::Proxy "socks5h://127.0.0.1:1080";
Acquire::https::Proxy "socks5h://127.0.0.1:1080";
Acquire::socks::Proxy "socks5h://127.0.0.1:1080";

And the proxy settings will be applied the next time we run apt.

Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

INSTRUCTIONS
1. Create a file with the following code
2. Put the file you want to convert into the same folder as it, and rename it to "py_file.py"
3. Add a "#F" comment to any lines in the code which have a function call that doesn't assign anything (so no =),
as the program cannot handle these convincingly
4. Run the converter file
