nano-node VS roadmap

Almost every Nano node release includes new features to make spam harder. I think it will be very hard to spam Nano nowadays. Despite not being in the spotlight and Nano dropping in value, the team is surprisingly active. https://github.com/nanocurrency/nano-node/releases

There's some pending work on the horizon to change the database side of things, which has projected storage savings of up to 50%.

"This change does not address block work pre computation as it's still possible to generate proofs for a time point in the future." - Source

Time-bounded proofs of work - All Nano transactions require a Proof-of-Work (PoW) instead of a fee, and that PoW (currently) never expires. This means that spammers can slowly create 100,000 transactions + their PoW, & then release them all at once. Time-bounding PoW would 1) allow nodes to better track/manage unconfirmed transactions (e.g. dropping the lowest priority transactions if the election buckets get full), and 2) could limit how long PoW is valid for, preventing attackers from stacking transactions for weeks or months, and 3) possibly allow normal PoW difficulty to be lowered (good for wallets/exchanges that make a lot of transactions)

Why would there be? As a developer, you generally don't broadcast roadmaps, because that's not the way development works. But even so, they have a generalized roadmap just for us, because people were asking: https://github.com/orgs/nanocurrency/projects/5

There is a little technical roadmap in the github: https://github.com/orgs/nanocurrency/projects/5

No idea. From Colin himself "I’ve seen the idea floating around that the spam attack was somehow a benefit to Nano and that it will speed up development. I can assure you this is not the case. We have several improvements lined up in the roadmap but not everything can be done at once. Unfortunately, this has slowed our progress toward v22 even more but we’re continuing to make the required improvements in the necessary order." [emphasis added]
