The industry’s quiet phase is the interesting one. Supply chain provenance, settlement, records and identity are where the substantive work sits now, well away from the token cycle that got all the attention.
Blockchain is a thing that had a hype cycle. Blockchaining is something you do, and the gerund suits this phase better because it reads as practice rather than speculation.
The .org is the right home for that. Standards bodies, open protocols, research consortia, developer foundations and industry associations all live there, and all of them need to sound like infrastructure rather than investment.
The name suits an education resource, a foundation, an open-source project, a certification body, or a publication covering enterprise applications.
One word, verbal form, no hyphen, and it sidesteps the crypto naming conventions that have started to look their age.
The name is listed. Offers welcome.
