An Empirical Analysis of Traceability in the Monero Blockchain

https://arxiv.org/pdf/1704.04299/

very elaborate, like the search for the planet x that is supposed to be by its gravitational trail, but nobody has found it.

What are purposes of the upcoming changes?
To control difficulty fluctuations better with new difficulty adjustments algorithm.
To avoid terrible rise in Monero difficulty due to sudden explosions of total hashrates in Monero network.
To make Monero network more stable.
 
I hope the coming changes will bring us good results for the project, it's miners, its network, it's price. Thanks.

How far along are multi-signature addresses in Monero? Judging by this pull request, I would assume they are already operational by using the CLI wallet? https://github.com/monero-project/monero/pull/3489

Multi-sig will enable Monero p2p FIAT on/off ramps and DEXs, and I think it is important to enable developers to create such (seeing as though regulators are stepping up their enforcement efforts and authoritative bravado.)

Quoting concerns in the comments section:

Isn't there a large risk of punishing innocent people? If you sell a hotdog to a maffioso and let him pay with bitcoin, should your money be voided?

A more concrete example:

Let's say Alice sells a painting on OpenBazaar that is bought by Bob. Alice assumes Bob is a law abiding citizin and thus sends her BTC to Coinbase to exchange them for US dollars. However, what Alice didn't know is that Bob isn't the law abiding citizen that she thought he was. That is, Bob occasionally sells some illicit stuff on the darknet markets and used his proceeds to buy the painting. As a result, Alice gets flagged by Coinbase for trying to sell "tainted" coins.

1. I really haven't gotten the chance to explore yet but are the devs of popular mining software getting a head start on the new algo and have already released or are in the process of releasing appropriate versions in time for the HF?

2. Also, wouldn't the network be in a vulnerable state since there will be a "theoretical" (though not actual) zero network hash rate at some instance during the transition since not every miner will be switching to the new PoW at the same time; more like gradually ramping up towards whatever the highest network hash rate will be?

Here's the problem though .. it locks up here and never moves. In fact it goes backwards ... getting the new blocks.

EDIT: In fact I had it open for 8 hours one time and no change.
Now it's doing nothing. It's like it stops listening.

EDIT AGAIN: It seems to be catching up.. very very slowly.  Thx

Here it is after 15 minutes open.

This? 5 seconds after I told it to connect to daemon.

EDIT: I'm running the latest version.

My wallet won't sync. Running windows v0.11.1.0. And I had the version before this.  They start with getting 1,000 blocks... then just sits there..for hours. I tried running as administrator ... set_log 4....and nothing seems to work.
It sometimes shows in green I have 12 blocks left. Then it goes back to orange saying 92,000 blocks left and freezes there for a long time.
Any help plz?  Thx

it was sent  in March 17, 2018 05:36  exchange bitfinex , I send it to your wallet  Monro !
With  Blockchain network manner
with following Transaction number
5b1576dd99c04d355f1f50efef6ce6805fb2870dc1f1ab68dfa4c465bb49e71a .but I don’t see nothing  was received in the Wallet , how is that possible?
What should I do ?

Thx for the link. 

Is this announced somewhere? The HYPE and FUD are really strong forces and big part of the crypto miners are like sheep /no offense/ they have no idea what they are doing, only money matters, so I guess many will be fooled around to buy some expensive ASICs door-stoppers.
