[bitcoin-dev] Fwd: Block size following technological growth

Anecdotally I've seen two primary reasons posed for not running a node:

1) For enthusiasts who want to altruistically run a node at home, it's
usually a bandwidth / quality of service problem. There are tools to help
work around this, but most users aren't sysadmins and would prefer a simple
configuration option in bitcoind and a slider / selector in the QT client
to throttle the total bandwidth usage. This issue has been open for years:
https://github.com/bitcoin/bitcoin/issues/273 - if you want to make it
easier for enthusiasts to run nodes, I'd start there.

2) For businesses, it's not so much an issue with the resources of
installing / running / maintaining a node, it's an issue with the lack of
indexing options offered by bitcoind. Thus the business will also need to
run their own indexing solution - an out-of-the-box solution such as
Insight or Toshi might work, but for more custom indexing you have to roll
your own software - this is where it actually becomes expensive.

Depending upon the query volume / latency needs of the business, it may not
make sense to bother administering bitcoind instances, the indexing
software, and its databases - using a third party API will probably be more
efficient.
