Server

For servers I've really come to love:

Hetzner.de
Contabo (word of mouth tells me it's good, I am a hetzner man)

Go and get one.  Single core, 2 gigs of RAM is fine.  Here you go, an exact link:
https://www.hetzner.com/cloud
You need a Hetzner cx11 cloud instance. Choose nvme, not ceph.
Configuration of server / dev environment

You are going to need node.js and Go, and you'll want the latest versions of both.
So you're going to SSH into that server like:
ssh root@ipaddress
Latest Go

NB: Paste lines one at a time or it could skip a step.
sudo add-apt-repository ppa:longsleep/golang-backports

sudo apt-get update

sudo apt-get install -y git golang-go make wget

export GOROOT=/usr/lib/go
export GOPATH=${HOME}/go
export GOBIN=$GOPATH/bin
export PATH=${PATH}:${GOROOT}/bin:${GOBIN}
Latest Node.js

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
Now install node using nvm, which is for installing node :)
nvm i node
Latest Protobufs

export PB_REL="https://github.com/protocolbuffers/protobuf/releases"
curl -LO $PB_REL/download/v3.15.5/protoc-3.15.5-linux-x86_64.zip
unzip protoc-3.15.5-linux-x86_64.zip -d $HOME/.local
export PATH="$PATH:$HOME/.local/bin"
Next, check your versions:
node --version
v15.12.0
go version
go version go1.16.2 linux/amd64
protoc --version
libprotoc 3.6.1
Install gh to make github smooth

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key C99B11DEB97541F0
sudo apt-add-repository https://cli.github.com/packages
sudo apt update
sudo apt install gh
Install Starport

curl https://get.starport.network/starport! | bash
Build your very basic blockchain

If it takes more than 20 minutes, let me (https://twitter.com/@gadikian) know, it means that something is wrong.
ensure that you have node.js, go and the github cli installed, detailed directions are provided for that above.
NOTE FOR TEAMS
Only the "lead" should do the step where the chain is built and pushed to github.
# Generate a blockchain with no frills
starport app github.com/yourusernamehere/instachain
# Add super basic blogging capabilities
cd instachain
starport type post title body
git commit . -m "Added blog feature"
git add .
# Push to Github
gh auth login # only do this if you haven't logged in already
gh repo create "instachain"
git push
THE PROCESS ABOVE

scaffolds a fast, secure, sovereign blockchain with a simple blogging feature
scaffolds a modern UI for that chain
generates binaries on github actions
generates a raspberry Pi device image that includes the UI and binaries as a Github Action
is an illustration of the capabilities of Starport
