but practically it wont work and would cause more issues, rather than benefits.

I'm not proposing this. I'm putting forward a system that is to my mind clearly broken, but then I claim that this is no different from the hypothetical Bitcoin in which miners have ultimate control, which is how a lot of people believe Bitcoin actually works.

well i think you are proposing a second database where each transaction accumulates upto 6000 signatures (because there are 6000 nodes) making a transaction chain bloated.

Only up to 40 distinct nodes are selected to be signers at any one time, and only 20 of them actually have to sign any particular transaction.
3  Bitcoin / Bitcoin Discussion / For those who think that Bitcoin is ruled by miners on: July 28, 2016, 11:21:57 AM
I'm often frustrated that a lot of people think that Bitcoin is absolutely ruled by the majority of miners, and that miners are kept honest only by various magical incentives. This is false, of course, but for those who believe it, I have a proposal for a far better new cryptocurrency:

The cryptocurrency has two chains, the mining chain and the transaction chain. The mining chain works just like Bitcoin except that it has a target time of 6 hours between blocks, and these blocks don't contain any transactions. Like Bitcoin, miners who mine a block on the mining chain get some coins. Say that the most recent block on the mining chain is MBlock 0. The miners who mined MBlocks 21 through 60 are designated "transaction signers".

To send a transaction, you create it, sign it, and send it to all of the current transaction signers. (In their blocks, signers will publish a public key and some IP addresses for contacting them.) If the transaction is valid, the signers will sign and date the transaction and return it to the sender. Signers get a small fee for this. The sender then gives the signed transaction to the recipient directly. The recipient knows it's valid because it's signed by a majority of the current transaction signers.

To keep track of the current ledger, the miners maintain amongst themselves a no-PoW transaction chain, which could just be one transaction per block. Since all transactions will be signed and dated by a majority of transaction signers, there can be no ambiguity about the correct ordering of transactions. Double-spending is impossible unless there's tampering by miners.

This has several advantages over Bitcoin:
- Transactions are always confirmed in seconds, and once confirmed they always have the maximum level of security (no need for a variable number of confirmations).
- End-users just need to download the mining chain's headers, which will be only a few MB in total, plus the most recent couple hundred full mining chain blocks, which will be another few MB. Non-miners only need to download their own incoming transactions.
- Since only miners need to maintain the current ledger info and see global transaction traffic, this is far more scalable than Bitcoin.

As far as I can tell, this network would have exactly the same level of security as a hypothetical Bitcoin network in which miners have 100% control over everything. For those who believe that Bitcoin is ruled by miners in this way, I put forward the following questions:

- If Bitcoin was intended to be ruled by miners, then why didn't Satoshi design Bitcoin as I described above? It'd be far simpler and better.
- If you see any problems with the above design, why don't they apply to your view of how Bitcoin works?
- In this design, what incentive do miners have not to collude together in order to create more coins than originally planned, or to steal coins from people? Maybe they wouldn't want to risk causing people to lose faith in the system, but whenever there is any possible justification for such action (deflation, stolen coins, etc), why wouldn't they jump at the chance?
- In the above design, what is the point of the mining chain at all? Wouldn't it be better to carefully select 20-40 extremely trustworthy entities to do the signing? In light of this, how do you justify any of Bitcoin's design?

In reality, Bitcoin is not ruled by miners because full nodes will ignore blocks that actively break the rules, no matter how many miners support such blocks, and full nodes can (and must) change the PoW function if miners are maliciously blocking or reordering transactions. It is absolutely essential for Bitcoin's security that a large chunk of the economy be backed by full nodes, or else Bitcoin devolves into a particularly inefficient version of the cryptocurrency I described above.

I am not really sure that I understand why, but according to theymos, after you have a certain number of PMs in your inbox, it will take longer to access your PMs. I have 515+ pages of messages in my inbox and it takes a noticeably longer amount of time to access my inbox, verses how long it takes me to access my inbox in accounts with ~20 pages of PMs.

It started being noticeably slow when I had 200 or so pages of messages in my inbox.

Right. When you load any PM page, it actually does some processing of all of your PMs. The SQL query is really complicated, so I haven't been able to figure out how to optimize this. (After you load one page, it'll be fast for a while due to caching.)

Also see:
I actually have code written for exporting PMs into an mbox file compatible with Thunderbird, but I haven't gotten around yet to figuring out how best to present this functionality to users. (It's unusual because it takes a bit of time to generate and the resulting file should maybe be encrypted.)

If any established members have a strong need for it, I can manually create an export for you. For example, if you have so many PMs that the PM page is slow to load for you, you can get a PM export from me and then use the "purge PMs" feature. I'll probably only do this one time per person...

Wow, that's a lot of expenses.  Was that calculated using the current price of bitcoin at the time that you paid those?  They were paid in bitcoins, right?

Yes, it's the value at the time of the transaction. All income and most expenses were paid in BTC.

The forum sells ad space in the area beneath the first post of every topic page. This income is used primarily to cover hosting costs and to pay moderators for their work (there are many moderators, so each moderator gets only a small amount -- moderators should be seen as volunteers, not employees). Any leftover amount is typically either saved for future expenses or otherwise reinvested into the forum or the ecosystem.

Ads are allowed to contain any non-annoying HTML/CSS style. No images, JavaScript, or animation. Ads must appear 3 or fewer lines tall in my browser (Firefox, 900px wide). Ad text may not contain lies, misrepresentation, or inappropriate language. Ads may not link directly to any NSFW page. Ads may be rejected for other reasons, and I may remove ads even after they are accepted.

There are 10 total ad slots which are randomly rotated. So one ad slot has a one in ten chance of appearing. Nine of the slots are for sale here. Ads appear only on topic pages with more than one post, and only for people using the default theme.

Duration

- Your ads are guaranteed to be up for at least 7 days.
- I usually try to keep ads up for no more than 8 or 9 days.
- Sometimes ads might be up for longer, but hopefully no longer than 12 days. Even if past rounds sometimes lasted for long periods of time, you should not rely on this for your ads.

Stats

Exact historical impression counts per slot:
https://bitcointalk.org/adrotate.php?adstats

Info about the current ad slots:
https://bitcointalk.org/adrotate.php?adinfo

Ad blocking

Hero/Legendary members, Donators, VIPs, and moderators have the ability to disable ads. I don't expect many people to use this option. These people don't increase the impression stats for your ads.

I try to bypass Adblock Plus filters as much as possible, though this is not guaranteed. It is difficult or impossible for ABP filters to block the ad space itself without blocking posts. However, filters can match against the URLs in your links, your CSS classes and style attributes, and the HTML structure of your ads.

To prevent matches against URLs: I have some JavaScript which fixes links blocked by ABP. You must tell me if you want this for your ads. When someone with ABP and JavaScript enabled views your ads, your links are changed to a special randomized bitcointalk.org URL which redirects to your site when visited. People without ABP are unaffected, even if they don't have JavaScript enabled. The downsides are:
- ABP users will see the redirection link when they hover over the link, even if they disable ABP for the forum.
- Getting referral stats might become even more difficult.
- Some users might get a warning when redirecting from https to http.

To prevent matching on CSS classes/styles: Don't use inline CSS. I can give your ad a CSS class that is randomized on each pageload, but you must request this.

To prevent matching against your HTML structure: Use only one <a> and no other tags if possible. If your ads get blocked because of matching done on something inside of your ad, you are responsible for noticing this and giving me new ad HTML.

Designing ads

Make sure that your ads look good when you download and edit this test page:
https://bitcointalk.org/ad_test.html
Also read the comments in that file.

Images are not allowed no matter how they are created (CSS, SVG, or data URI). Occasionally I will make an exception for small logos and such, but you must get pre-approval from me first.

The maximum size of any one ad is 51200 bytes.

I will send you more detailed styling rules if you win slots in this auction (or upon request).

Auction rules

You must be at least a Jr Member to bid. If you are not a Jr Member and you really want to bid, you should PM me first. Tell me in the PM what you're going to advertise. You might be required to pay some amount in advance. Everyone else: Please quickly PM newbies who try to bid here to warn them against impersonation scammers.

Post your bids in this thread. Prices must be stated in BTC per slot. You must state the maximum number of slots you want. When the auction ends, the highest bidders will have their slots filled until all nine slots are filled.

So if someone bids for 9 slots @ 5 BTC and this is the highest bid, then he'll get all 9 slots. If the two highest bids are 9 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 8 slots and the second person will get 1 slot.

The notation "2 @ 5" means 2 slots for 5 BTC each. Not 2 slots for 5 BTC total.

- When you post a bid, the bids in your previous posts are considered to be automatically canceled. You can put multiple bids in one post, however.
- All bid prices must be evenly divisible by 0.05.
- The bidding starts at 0.25.
- I will end the auction at an arbitrary time. Unless I say otherwise, I typically try to end auctions within a few days of 10 days from the time of this post, but unexpected circumstances may sometimes force me to end the auction anytime between 4 and 22 days from the start.
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bids are considered invalid and will be ignored if they do not specify both a price and a max quantity, or if they could not possibly win any slots

If these rules are confusing, look at some of the past forum ad auctions to see how it's done.

I reserve the right to reject bids, even days after the bid is made.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else, and I might even give you a negative trust rating. I will send you the payment information via forum PM from this account ("theymos", user ID 35) after announcing the auction results in this thread. You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.

What would you consider to be part of the economy that should be backed by a full node?

Nobody should use EWallets. Casual users might use lightweight nodes, preferably with fraud proofs (which don't exist yet, but hopefully will in a couple of years). As many people as possible should use their own independent full nodes -- certainly anyone who accepts transactions automatically.

There are several plausible ways that full nodes could be distributed securely. I've recently been thinking that it might be best for the vast majority of Bitcoin trade to move to dedicated hardware. End-users would have something like a Trezor, which would operate as a lightweight node with fraud proofs, and businesses, both online and in-person, would have dedicated Bitcoin-acceptance devices which would contain full nodes. This also helps a lot with the various security issues.

Other possibilities/ideas:

- Everyone runs a full node on all devices. This is possible with aggressive pruning.
- Most people use lightweight wallets with fraud proofs, and all merchants run independent full nodes. (Unfortunately, history has so far shown that businesses are even less likely to set up full nodes than end-users.)
- Everyone has a dedicated Bitcoin "base station" device at home which acts as a full node and something like an Electrum server, and all of their wallets connect to this device.
11  Other / Meta / Re: Petition: Change owner of ethereum thread on: July 21, 2016, 10:17:46 AM
I don't follow altcoins at all, but it seems to me that Ethereum's main problem here was that its economy wasn't backed by very many full nodes at all. See:
https://en.bitcoin.it/wiki/Full_node#Economic_strength
https://bitcoin.org/en/bitcoin-core/features/validation

I'd guess that 99% of ETH owners were using EWallets. This is extremely dangerous, since it gives those EWallets massive control over the network. This is exactly the sort of centralization risk that Bitcoin experts are constantly warning about in relation to the max block size. It is absolutely essential that the economy be backed by many independent full nodes so that miners + a small handful of "major players" can't completely change the currency.
12  Other / Meta / Re: Petition: Change owner of ethereum thread on: July 21, 2016, 09:35:04 AM
The forum isn't going to get involved in this sort of thing. In almost all cases, thread ownership isn't changed except with the original owner's permission. You should create a new topic. Also, if he is being deceptive, then this may warrant negative trust.
13  Other / Meta / Re: Unable to establish secure connection on: July 19, 2016, 09:07:02 PM
That's often caused by a TCP RST near the start of the connection. I think it's probably a problem on your end, maybe exacerbated by some configuration on the forum's end.
14  Other / Meta / Re: List of all forum boards on: July 14, 2016, 03:13:59 AM
Like a sitemap or something? Bitcointalk.org sitemap does not look like the site map of an corporate site https://bitcointalk.org/sitemap.php?t=t&p=36
The main board is different from having a list of boards.

The sitemap for boards is: https://bitcointalk.org/sitemap.php?t=b

15  Other / Meta / Re: Question about Private Messaging a Group of my members on: July 13, 2016, 05:21:54 PM
Have the "to" field be addressed to yourself and have everyone you want the message sent to be in the "bcc" field.

You can leave the "to" field blank, even.

He is most likely taking advantage of those with poor security (through either phishing or using older password hashes as Lutpin suggested). As long as you use good security practices I expect you have very little to worry about.

Yes, he's going through the leaked password hashes from a year ago and trying maybe a few 100k simple passwords per hash. If you changed your password since May 2015, then nobody's going to get your password in this way. (I emailed everyone about the need to change passwords at the time...)
20  Other / Meta / Re: I just hacked 3 and scammed 3 members. on: July 10, 2016, 04:42:49 AM
The three accounts he's talking about are:
jylee1997123
phosphorush
stealth923

They were all almost certainly hacked using the password hashes that were leaked a year ago -- these users never changed their password since then, and were probably using fairly simple passwords.

For all of these users, I randomized their passwords and changed their email addresses to their initial values. So if they return, they'll probably (though not certainly) be back in the hands of their original owners.
