Re: challenges of blockchain growth and potential solutions
- Block Size Limit: What is the community's stance on potentially adjusting the block size limit to manage growth? Are there ongoing discussions on this topic?
Some people want larger blocks, I have not seen someone discuss smaller blocks for ages unless it's done as a part of some sarcasm like this one
That's exactly the reason we need to decrease the blocksize to 100 kb to kill all possible spam!

I've been pondering the relationship between ordinals and the increasing block size in Bitcoin. How do you think the ordinal approach could impact the scalability of the blockchain?
Ordinals do slightly contribute to larger blocksize although by nature those transactions are not large, but more transactions = larger blocksize (although not always), but ordinals are not to blame, the block size based on consensus can be as large as 4MB on the desk, while it's possible on paper, it's going to be very difficult to construct a large amount of block at 4MB not even 3.5MB unless it contains some weird transactions, but one would assume that the worst case scenario would be 576MB of daily added size, roughly 200GB a year which is obviously very unlikely to happen since most blocks are "natural" and they won't fill 4MB worth of transactions, take last year's average and it would be roughly 1.75MB, say 2MB and that would be an average of 100GB added per year.
For cloud storage, you are looking at an average of $10-$20 a year, the VPS I use charges $2/month for an extra 200GB SSD so that would be an extra $12 a year (you can certainly find cheaper offers), for normal disk storage 'which is good enough for the use case' it's probably 1/3 the price.
As it stands right now, you can get a decent VPS with 1TB storage for $12 a month, I suppose many folks who run a full node have not yet faced disk issues yet, and storage would only become cheaper over time, so + 100GB a year is not a concern IMO.
