I hope I can explain it to you without complications on my part due to lack of knowledge, but from reading the Falcon Crypto compared to Elliptical Curve Crypto it's replacing there is around 8 different Encrypted Buckets to generate 1 Half Falcon "Curve" and like 1-2 are Random Salts so even if the original value used for Falcon Encryption is known it will be randomized multiple times before it gets used the Value............each stage of the Bucket is RE-ENCRYPTED with a New Key
This is only 1 Half of a Falcon "Curve"
To break Tidecoin you still need to break other encryption standards as well.........it's also not just Falcon but NTRU-Falcon
Elliptical Curve basically uses a randomized salt to generate a curve so to calculate it's value is child's play compared with breaking NTRU-Falcon!
And Falcon has already been selected as a Final Candidate to be used!
The Blockchain size for Tidecoin compared to Arielcoin is vast......and Tidecoin has been around 1 year longer..........Arielcoin is well over 5GB data.........if Blockchain size even matters in the future which it may not...........BUT it might so it's still a factor! Especially with the unknown factor of Arielcoin now using "Smart Contracts"
Tidecoin best development goal is to just update the Core Rebased into Litecoin newest version where Tidecoin will than have Mimble-Wimble Extension Blocks and not even worry about Smart Contracts as Litecoin has Taproot as well I think which is the basis for minimalist Smart Contracts!
Which from Tidecoin.org roadmap lists that as a goal, but I am unsure if they mean Bitcoin codebase or Litecoin as Tidecoin is original a Litecoin Codebase and should stay that way as it's the best YesPower Mining performance!
If I had to guess however, it would be that they are generating fancy articulated documents to cover their tracks of requiring backdoors into ALL Computer hardware to adhere to the "Digital ID"
Them breaking Post-Quantum Encryption standards that have already been Finalized and Accepted like NTRU-Falcon is not likely!
