skateboarding is a very bad example here - there is a noticeable difference in the quality/bearings of a "beginner" equipment that comes from Walmart/Target that costs ~60, and a proper setup from a skateboard shop that costs ~120.

The beginner equipment is more likely to get you hurt by breaking, and the bearings will be very very slow.

For other sports, running/biking/skiing/etc I think this difference is not as pronounced.

What are the advantages of Empirical vs q/kdb+?

elliptic curve is a type signing algorithm (like blake2b or sha). if you dont understand what an EC is i dont think you also understand why rolling your own would be a bad idea. the wallet/account seed (your post is semantics in my opinion, whichever seed it is you can only use once, which is a flaw) is directly related again to this issue.

IOTA is vaporware and gives all blockchain projects a bad reputation by association. You are right on your points and forget that they rolled their own elliptic curve so you cant use a wallet twice.

the lack of awareness around nano is puzzling to me. I assume its because nano became known around the end of 2017 along with many scam coins, and thus became associated with them.

but today if you described implementing a gossip protocol with nanos features (permissionless decentralization, 0 fees, <1s tx), many people would say it is impossible, but here we are with a 4 year mainnet with no serious issues

im not sure why this is being downvoted. this is clearly the case here.

the user and the miner are colluding (or the same party). the user does not broadcast their tx publicly, only sending it to the colluding miner. since fees have no utxo history, this essentially launders the eth

No problem! Not much of a pedigree, but I think the articles stand by themselves.

this is a poor ripoff of Lyn Alden's work:

tezos is attempting to solve this by incorporating on-chain governance - its dPoS and has a code deployment mechanism with a long voting process (multimonth). They have done 2? upgrades now and quorum seems to be ok so hopefully they can keep up voting %

i still think the nano (formerly raiblocks) approach is cool - it scales by running parallel blockchains - each wallet is its own chain. tx's between chains are voted on weighted by % stake - dpos without lockups or slashing. this way its not a competition for space in a single ledger, its competition for voting bandwidth on the worst marginal node. a better tradeoff imho. downsides: the ledger also grows larger quicker than btc (because theres no 7tps limit so you can spam it)

no voting rewards or inflation - theres no on chain incentives for voting at all, but exchanges/pos need to run full nodes to validate ledger anyway and voting is trivial bandwidth. its elegant and the security model works but its hard to tell people about without coming across as a fanatic.

Cool writeup! Although I agree those captcha's are fairly trivial.

In college I wrote a term paper on breaking Microsoft's captcha (which is a little harder but not by much) twice: first with a simple template-based classification method and then a CNN approach.

At the end, we go over approaches that would help captchas fight attacks. I think the quick flickering approach would work best (split the image into uneven parts, flicker them quickly so the human eye can read the aggregate image but any single slice doesn't show the full picture, and the superimposed image is incorrect)
