Can we create a smart contract VM on nodejs using Dat?

Ethereum is a trustless network of VMs which run smart contracts submitted by users. It uses proof-of-work to synchronize state across the network, and has every node execute the contracts in order to verify the state's validity. Each transaction is stored in the blockchain for replayability. Read more about it here.

Ethereum's "trustless network" model has some disadvantages:

Transaction processing is slow - it maxes at roughly 25tx/s right now for all contracts combined.
Every transaction costs money to execute.
The entire blockchain state must be shared across the computing network.
No private transactions.

OverEncrypt

This is a guide that I wrote to improve the default security of my website https://fortran.io , which has a certificate from LetsEncrypt. I'm choosing to improve HTTPS security and transparency without consideration for legacy browser support.

WARNING: if you mess up settings, lose your certificates, or decide to no longer maintain HTTPS certs, these steps can and will make your domain inaccessible.

I would recommend these steps only if you have a specific need for information security, privacy, and trust with your users, and/or maintain a separate secure.example.com domain which won't mess up your main site. If you've been thinking about hosting a site on Tor, then this might be a good option, too.

The best resources that I've found for explaining these steps are https://https.cio.gov , https://certificate-transparency.org , and https://twitter.com/konklone

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
