Any methods or tech to reduce the size of blockchain? Are there any techs/methods applied or going to be applied on the bitcoin network to reduce the size of blockchain. It is really a burden for peroson to run a full-node especially on vps. Or what other coins successfully dealed this storage problem?
In cases like VPS it seems that the storage on plans rarely increases much despite HDD size increasing nearly ten-fold since the beginning of 2009.

Depending on how you use the node there are several options to reduce storage requirements. Here are a few:


Enable pruned mode on the node.
Use an SPV client like Electrum in place of Bitcoin Core.
Enable inline file compression (if available) i.e. btrfs compression.
