Hi, quick update.

I’m gonna switch the smart contract from `ink!` to `solidity`. I dunno if anyone really cares to know this, but thought I should report it nonetheless for transparency’s sake. Also, I don’t expect this initial switch to take more than a few days.

The reasons for this switch are

1. the service I was depending on to validate the `ink!` smart contract, `polkaholic.io` via `ChainIDE`, is currently down (The outage has apparently been noticed by others a while ago, but, since it’s still down, I don’t expect it to come back up anytime soon) and

2. other services for verifying `ink!` smart contracts, as detailed in articles and blog posts, are also down.

Plus, given that I feel fairly familiar with `solidity`, I expect switching to solidity is gonna prove much less of a hassle.
