Security of the Blockchain against Long Delay Attack

Abstract
The consensus protocol underlying Bitcoin (the blockchain) works remarkably well in practice. However proving its security in a formal setting has been an elusive goal. A recent analytical result by Pass, Seeman and shelat indicates that an idealized blockchain is indeed secure against attacks in an asynchronous network where messages are maliciously delayed by at most Δ≪1/npΔ≪1/np, with nn being the number of miners and pp the mining hardness. This paper improves upon the result by showing that if appropriate inconsistency tolerance is allowed the blockchain can withstand even more powerful external attacks in the honest miner setting. Specifically we prove that the blockchain is secure against long delay attacks with Δ≥1/npΔ≥1/np in an asynchronous network.

Here is what happens under the hood of a Bitcoin transaction

Have you ever wondered why a Bitcoin transaction has a thing called confirmations? Or why the network can be 'clogged' and processes Bitcoin transactions very slowly on one day, whereas it does so quickly the other? And do you know how transaction fees work, why they jump and decline? Maybe you already know it is related to the volume of transactions, but there is much more too it than just that, because that basically explains us.. nothing.
What happens under the hood? What steps are involved and why?

This 5 minute explanation is a must read and takes you through a Bitcoin transaction under the hood in 7 simple steps: lets find out if you actually know how it works.

What Bitcoin technical videos/podcasts would your recommend?

Love Andreas but I need deeper and more complex material. I'm slowly trying to understand the conversations being made in the Bitcoin mailing list but I often get lost with their terminology. Looking for something I can listen to as I work or walk that attempts to explain Bitcoin under the hood. Thanks hodlers.

[Q] Would anyone be interested in a trading site similar to Dota2Lounge, but with an automated middleman service?

I've been doing professional web development for a few years, and I love Dota 2 and the trading scene.
Something I think we're lacking is a way to easily send money to someone for items with no risk or the inconvenience of a proper middleman. I think this easy currency exchange is going to get more important when keys are removed.
A working name for this site is Wex.
Here's how it will work:
Someone posts a trade exactly like d2lounge. People find this trade, and there are three options: Add on Steam (to discuss or trade there) Send trade offer (through Steam) or finally Send trade offer (through Wex).
The trade offer through wex will be remarkably similar to Steam's trade offer window, except that it will have an option to add USD on either side.
So an example trade could be: I offer 1 Timebreaker for your 3 arcana and you add $10.
or I offer $100 for your Timebreaker.
Then, when the trade offer is sent through Wex, the site sends a trade request to the person making the request to get their items (if necessary) and holds them. Then if the person being offered to accepts, Wex sends them a trade offer asking them for their items, then Wex swaps the items between the two traders through two more requests.
So the total process would look like this: 1. Trader1 sends request to Trader2. Trader1 will trade 1 Timebreaker and $70 for a Dragonclaw hook. 2. Trader1 sends his Timebreaker to the Wex middleman. 3. Trader2 accepts. Sends Dragonclaw hook to the Wex middleman. 4. Wex gives Timebreaker and $70 to Trader2. Gives Dragonclaw hook to Trader1.
All monetary transactions would be in USD, but be Bitcoin under the hood.
Anyone interested? How do I make it as safe and trustworthy as possible?
