Counterparty and bitcoin blockchain pruning

Hey guys. I'm new into counterparty. As I understood, counterparty protocol "lives" inside the bitcoin blockchain, by storing information in it. Previously I heard that with growing BTC blockchain there could be implemented BTC pruning, e. g. some of the information from the blockchain can be removed to decrease it's size. I was wondering how this will affect counterparty, can it make this protocol completely broken? Thanks for answers and sorry if my english sounds bad.

The Bitcoin blockchain (pruned) will never grow bigger than a some hundreds of terabytes - since there is a finite number of Bitcoins, there is a theoretical maximum to how big the UTXO set can be.

Assuming 300 bytes for each UTXO definition, and each UTXO is 1 satoshi - 630 Petabytes. Of course in practice when you have addresses that hold hundreds or thousands of bitcoins, the size in practice will be much much smaller than the figure above.

bitcoin-qt ready for use within half an hour … download an up-to-date pruned blockchain

Let us discuss how safe this is :-)
This tutorial is for Linux only but people using other operating systems will understand what to do.
Download the bitcoin blockchain
https://drive.google.com/drive/folders/0B0nH34wIYOSlSG81ZUZUZGZjVkE?usp=sharing
This will download (~20 minutes) the 2485 MB file:
bitcoin_blockchain_pruned_550MB_19aug2016.tar.gz
It contains only blocks, no wallet or log files. It has been created with -prune=550
Unpack
tar -zxvf bitcoin_blockchain_pruned_550MB_19aug2016.tar.gz
and observe it contains only blocks and chain state data. This will create the directory:
.bitcoin_pruned_550MB_19aug2016
Let’s assume you move this to ~/.bitcoin_pruned, so
mv .bitcoin_pruned_550MB_19aug2016 ~/.bitcoin_pruned
Run bitcoin-qt
When you start bitcoin-qt, a new wallet will be created: back it up first. My advice is to use bitcoin-qt 0.13.0rc3, because it creates a HD wallet that never runs out of addresses.
Start bitcoin-qt in fast start-up mode first:
bitcoin-qt –prune=550 –checklevel=2 –checkblocks=10 –checkblocksverify=10 –datadir=yourpath/.bitcoin_pruned
and let it sync quickly. Check more thoroughly next time with 10 -> 500000.
You can have a quick look at what’s happening:
tail ~/.bitcoin_pruned/debug.log.
 
FOR NOW, the drawback is that if you want to add addresses (watch-only or spendable) that already contain bitcoins, you have to create the pruned blockchain from scratch yourself, which takes a lot of time (or have someone with a full blockchain rescan the wallet for you). This is not really necessary: if the user is not interested in the history of his transactions, the balances can be obtained directly from the UTXO set. It has already been approved to add this feature in some future Core release:
https://github.com/bitcoin/bitcoin/issues?q=is%3Aissue+is%3Aopen+label%3AWallet, #8497.
I will automatically update the google drive with new up-to-date blockchains soon.
EDIT:

Is it possible to host a pruned bitcoin node and node.js server on digital ocean to access network and blockchain data 24/7 affordably?

I have heard it has been possible for years to host a bitcoin full node on a VPS like digital ocean and that the cost now is approx $60/month with potential to increase drastically over the next few years with segwit adoption.
Is there a good approach for hosting a pruned node with access to 24 hour or potentially 30 day block data in addition to a node.js server to save occasional writes to a DB? Would one have to host these on seperate droplets or is there a possibility to host both on a $5-10/month digital ocean account? I am curious because I have only seen tutorials for setting up full nodes but those will soon be potentially >$1000/year in upkeep.
I am curious to see if it is possible to host my server in the cloud rather than update the DB locally. I understand a full node is important for network security, but this use case is more for current and recent bitcoin blockchain data, rather than the full tx history.

Bitcoin on-chain pruning can eliminate the problem of blockchain size growth completely

I'm quite new to Bitcoin and I thought about how to improve scalability that everybody is talking.
I've written a concept of on-chain pruning, which in theory will eliminate the problem of growing blockchain size.
