Is it possible that in the future that the blockchain could be truncated and archived off? For example, are the miners still interested in transactions < block 100,000. If not why keep it on the blockchain indefinitely if it no longer computationally relevant? To cut down the size of the blockchain could it not be truncated at say block 100,000.

For personal use, you can use the prune option... when using this option, i think the blockchain is somewhere around 6-10Gb (untested by me)

I tried prune mode before at a size of about 5GB. It worked but at that time it didn't support wallet function so I switched back to the full blockchain mode.

By the way, even if you are running the prune mode, bitcoin-qt will still download the full blockchain and process it to give you the pruned version based on the maximum size you have set...

If you use electrum then only the headers are stored, which is only 33 Mb , the real blockchain will be terrabytes size before the electrum lightweight will be 1 Gb, so it will be lightweight forever.

Sure, but i wasn't talking about electrum... I was talking about core and downloading the full blockchain vs using the prune option because the OP said he wanted to reduce the size Wink

Any SPV wallet will be a lot smaller, but these wallets still need servers that actually run bitcoind and sync the full blockchain.

It's not possible to completely forget such transactions. Because coins from these transactions would be in different addresses now. Without the knowledge of these old transations you would not know that there are coins in some addresses.

Or transactions would even be invalid.
