THELOGICALINDIAN - n-a
Grin Coin is a community-based activity that launched with no “funny business”. It’s natively private, lightweight, aggressive to ASIC mining, and it has fabricated a big appulse on the crypto area admitting the advancing buck market. It’s based on Mimblewimble.
“Grin empowers anyone to transact or save avant-garde money after the abhorrence of alien ascendancy or oppression. Grin is advised for the decades to come, not aloof tomorrow. “
No big promises, no big statements, apple-pie amount proposition. Off to a acceptable start.
“Grin has no amounts and no addresses. Transactions can be trivially aggregated. To adumbrate area a anew created transaction comes from, it gets relayed abreast (a “random walk”) amid aeon afore it is about announced.”
“MimbleWimble leverages cryptography to acquiesce best of the accomplished transaction abstracts to be removed.”
I’ve covered MimbleWimble a few times afore in added appear reviews, so I won’t go into it to much, if you charge a refresher you can attending at my Beam review or my accompaniment absorption article.
1,856 commits, 109 contributors. I’ll echo 109 contributors. That is a attestation to accessible antecedent work, no ICO, no big-ticket developers (and yes, blockchain developers are crazily expensive, aloof abacus the chat blockchain to their CV and they up their bacon by 300%… that’s a bluster for a altered day, let’s dig in)
Rust development language. Normally I would skip the boiler plate, API/RPC/Crypto, but in this case I anticipate it speaks a lot appear the all-embracing project, back the amount actuality isn’t how they do the “unicorn” stuff, but instead how they do the basics.
Great encapsulation, attractive at the cipher shows appropriately absurd abstraction;
Concise, able-bodied called and anecdotic functions.
When functions aren’t cocky anecdotic they add ample comments;
Very accurate and abridged code. I’m activity to run through the blow of the boilerplate, but so far it confirms my suspicions, this is a abundant cipher abject to assignment off of.
/config/ is good
/util/ is good
/storage/ is good
A quick agenda on development. As a developer you generally alpha out with a requirement, and your aboriginal cipher is beautiful, if fits that claim perfectly, it’s able-bodied designed, architectonics is solid, aloof the appropriate antithesis amid absorption and affluence of readability. Then appear the ambit changes, and added requirements, and deadlines, and actual bound that already admirable assignment of art changes to a abhorrent blend of spaghetti code.
All acutely authentic projects alpha out beautiful.
This is a admirable archetype of that, the blueprint was clear, what they capital to accomplish was clear, and the cipher is beautiful. Will it still be this admirable in a year from now afterwards ambit creep? How will this admirable cipher abject board changes? I don’t know, I’m aflame to see though.
Wonderful affidavit aloof as an fyi, abundant abode for anyone to alpha that wants to apperceive added about Grin.
Enough of the boilerplate, time for amount and chain.
We appetite create_pow_context, and find_cycles()
I absolutely don’t accept abundant animadversion on the above, it’s absolutely what they accompaniment it is. So… acceptable job.
Short hashes for compacted blocks. Didn’t alike apprehend about that. Cool idea.
A freakishly simple, but admirable accomplishing of compacting.
block.outputs — get all outputs in the block — filter out |x| x.is_coinbase() — cloned — collect.
Cut through compacting.
Grin Code Review Conclusion
Rangeproofs, cut through, Pedersen commitments. This is absolutely what it set out to be, a defended (pow), clandestine (rangeproofs), compactable (cut through) broadcast band-aid congenital absolutely accessible source.
What I’ll add, it was congenital with passion, dedication, and love. The builders should be proud, it is a assignment of art. Simple, yet elegant. Concise, yet descriptive. Abundant accomplishing of a abundant idea.
