To do this I want to utilize the forum search function, and to do that I need to use an account.
This will not work very well. The forum search function is a) not very good, and b) very resource intensive on the forum's server.

A superior way of doing this would be to use the See unread posts since last visit page, review the last pages of threads on this page until your bot gets to a post it has already reviewed, and check for keywords in-between the following:

3322  Bitcoin / Development & Technical Discussion / Re: What is an appropriate reaction to dealing with Well-Poisoning Attacks on: August 18, 2019, 04:29:23 PM
Reddit and craigslist both closed subs on their platforms that allowed people to create listings that directed people to contact them via email or text to arrange a meeting. This was done in direct response to the law, and the law was intended to do this. From what I have read, some people offering their ‘services’ were actually being forced to do this, but it was not obvious on the fact of the advertisement. I’m not sure how prevalent this was, but it was apparently common enough so that Congress put a stop to it.

I see, but using blockchain to message others is stupid idea for those who need privacy (either because good or bad reason).

If it's unencrypted, government/blockchain analyzer could analyze the content easily unless obfuscation is involved.
If it's encrypted, both participant must exchange public/private key before hand. Additionally, there's size overhead when use encryption which is "big" enough if participants use Bitcoin's blockchain.

My understanding is the craigslist and reddit subs were public and available to anyone with an internet connection. The subs were a way to advertise services and the ads requested those interested to contact them off site. Anyone potentially advertising their services on the blockchain would have the same amount of privacy as those who were advertising on craigslist and reddit before the subs were taken down.

Those offering their services can have privacy by using a throwaway email address or telephone number. Those consuming the services would have no transactions, and would only need to read the ads.

You could easily feign conversations and have all your accounts accompany one another in the same threads, lowering the amount of time for searching through viable threads of meaningless discussion.
It should set off red flags if the same group of people are always participating in the same threads. If you compile a DB of everyone's posts that includes at a minimum the thread ID, this should be fairly simple to detect, and if the reply number, or the date/time of the post is also tracked, one should be able to detect this with few false positives if a sufficiently strict criteria is used.
3324  Economy / Lending / Re: Need a loan of 0.3 Bitcoin, (100% Collateral available) on: August 17, 2019, 09:29:56 PM

Type of Collateral: My BITGO Wallet, where I am holding around 0.4 Bitcoin, you will receive Password + 2FA , you can change the Password and set the 2FA for yourself,  but you are strictly not allowed to move out any funds. Once I have paid back, you give my Wallet with my Funds back.
This is not secure.

BitGo only controls one of three private keys associated with addresses where coin is 'stored'. Two keys are required spend the coin.

The customer's "primary" key is designed to initiate all transactions. The customer will sign transactions with this key, and provide the signed transaction to BitGo, who will then verify the requestor is authorized to request that BitGo sign the transaction based on account settings. If all requirements are met, BitGo will sign the transaction. There is a 3rd key, held by the customer, designed to be a "cold storage" key, that can be used in conjunction with the "primary" key to spend any coin within the address.

The above means, that the lender will be unable to spend any coin within the wallet, and the OP would be able to move any coin held in the BitGo wallet.

the data is public

Where is the data housed? I don't think this would be a terribly difficult project if the data doesn't need to be cleaned too much.

That being said, all three of these companies are private, and I would be surprised to see any of this information public, except for the cost of individual rides.

I don't need the exact numbers but to get some sort of reference.
A lot of information is available online, mostly in states which they demand this information to be public (US based companies).
I am not aware of any laws within the US that require expenses to be public for private companies. Even public companies generally do not have this granular information publicly available.

I found this article that says Bird's rates vary by location/city to between $0.1 and $0.33 per minute, with a $1 upfront charge. I found a couple of articles that all cite Lyme's rate to be $1 plus $0.25 per minute.

It appears these types of companies pay contractors to charge their scooters, who are also paid a variable rate. I have found various articles that cite contractors being paid between $3 and $25 per scooter, and between $5 and $25 per scooter, and all the articles I found implied the average tends to be on the lower end of this scale. I am not sure how often they need to be charged.

Bird sells a version of their scooter that has a range of 30 miles for $1,300. I would put an upper bound to the costs of the scooter to be 90% of this cost, but would estimate the actual cost be much lower than this. I found an article that cited the cost of a scooter to be $551.

The revenue per scooter per day is going to vary widely by location, and will be difficult to estimate without some kind of at least sample data. This article cites the average ride on a Bird scooter to be $3.65, and an average of 5 rides per day per scooter, both as of May 2018. Assuming $0.25/minute, you could reach the conclusion that each Bird scooter is driven for an average of 10.6 minutes per ride. This would also mean that scooters will need to be charged at least once every other day.

I found a Crunchbase article that sums the ultimate information you are likely looking for; Bird has gross margins of 18% as of May 2018. This was according to an investor presentation. At the time, Bird reportedly said they hoped to increase gross margins to 33% by reducing operating costs.

None of these companies are autonomous, and will have costs such as software development, scooter R&D, and others.

Also, without at least pointing to any kind of raw data, you are not looking for a data analytics project to be completed, you are looking for a google search project to be completed.

Congress passed an exception to section 230 of the CDA recently, in that service providers no longer have protection from liability in cases of sex trafficking.  I don't think law enforcement would go after a node operator if the blockchain stored on his computer has unprotected communications or content because his intent is not clear. Law enforcement may go after whoever uploaded said content using blockchain analysis.

I don't see direct correlation between storing data on Bitcoin blockchain and sex trafficking since anyone can see the data.
Reddit and craigslist both closed subs on their platforms that allowed people to create listings that directed people to contact them via email or text to arrange a meeting.

It would probably be best if congress were to pass a law explicitly protecting node operators.

It won't happen anytime soon, at least until congress made decision about law about cryptocurrency.
The CDA was passed when the internet was in its infancy. From the perspective of how widely used crypto is today, the crypto sphere is far past when the internet was when the CDA was passed.

That depends on the law on your country and whether malicious party only include link to illegal content or embed the illegal content on Bitcoin blockchain (which would be very expensive, without pool help & 0-fee transaction).

If the malicious party only include link to illegal content, report the link to the authority (unless it's link of P2P-based protocol) should solve the problem since the link would be useless (after it's taken down/blocked by authority).

Otherwise, you should hope there's law such as Section 230 of the Communications Act and Section 512 of the Digital Millennium Copyright which protect you.
See Why Porn on the Blockchain Won't Doom Bitcoin for more info.

Personally, it's worrying, but i doubt they'll go after individuals who run full node because there are many ways connect to bitcoin network or blockchain explorer.
The tool linked by the OP is designed to upload data onto the 'Bitcoin Satoshis Version' ("BSV") blockchain (despite its misleading name, this altcoin is NOT "satoshis version" nor implementation of bitcoin). BSV has the capability of handling very large transactions because of its large max individual block size. This means someone could potentially upload an actual file to a BSV transaction.

The DCMA will only protect against copyright violations, and includes a requirement that copyright content be removed upon request by the copyright holder. I don't think a copyright holder would go after full node operators if the blockchain of the coin of their node has copyrighted material because the damage would be negligible, and it would be technically difficult to remove said material.

It was appropriate to deny entry into Israel, considering they both want to see Israel's people murdered and country invaded.

They are also supporters of boycotts of Israeli businesses. The trip was clearly meant to advance their anti-semantic agenda.

After they were denied entry, Talib has asked to be granted entry into Israel to visit her Grandmother (she was probably hoping to be denied, so she could use the denial as propaganda), and once she was granted a visa that would allow her entry, she announced she will not visit. After all this happened, Trump tweated that Talib's grandmother was the winner in the ordeal because she wouldn't need to see Talib.   
3330  Other / Meta / Re: Should Evil fees have a maximum? on: August 17, 2019, 04:15:53 AM

Can you have a way to track how many people registered, were prompted to pay a fee, didn’t pay, and subsequently registered a different account (both that did and did not require a fee). Something other than IP address would need to be used to track this.
That would go against many things this forum stands for.

Further reading:
A year or two ago I was researching fingerprinting techniques that'd work against pretty much anyone with JavaScript enabled, and I found several promising leads on that front. But then it occurred to me that I don't really want bitcointalk.org to be known as the #1 forum on the leading edge of de-anonymization technology, so I stopped pursuing it seriously...
It is not necessary to rely on NSA (or Chinese government) level spying to track what I was referring to. I was referring to something closer to tracking cookies that can track your activity. I believe these can help detect things like if accounts are being hacked, for example if someone is accessing an account with the same browser type and IP range as normal but without a cookie that has previously been consistently present when accessing an account. I also believe these can pretty easily be removed, so if you don’t want this type of tracking, it is trivial to stop it.

I believe there are other types of tracking that doesn’t require NSA level spying.

The quote you cited was referring to very advanced tracking when the person being tracking is taking many steps to avoid being tracked. I don’t believe even the likes of Google and Facebook employ the types of tracking referred to in your quote.

Full access to private keys

This is only true for their "on chain" wallet and not their LN wallet, both of which are available within the app. The Blue Wallet LN wallet is custodial, meaning the operator of Blue Wallet has control and custody of the coin within an open LN channel. Blue Wallet advertises their LN wallet to be intended for only small amounts of coin.
3333  Bitcoin / Wallet software / Re: Bitcoin Sending Fee - Indonesian Experince on: August 16, 2019, 06:13:43 AM
Good evening ,

Hi I need some advise, as Indonesian we only familiar exchanger like Indodax.com , luno.com or binance
I just curious which wallet or exchanger have low fee for sending bitcoin , sometime I just to invite my friend to using bitcoin (giving him/her little bit satoshi) but if I sending to Indodax or Binance fee sending is 0.0005 btc . please advise also why they have difference cost fee (IMHO speed sending is same)
The most convenient way to store your Bitcoin is to have a wallet of your own like Electrum or a hardware wallet. You can send Bitcoin will the lowest possible fees like, 0.00000226BTC

So my suggestion will be to ask your friend (teach him if needed) to have a Bitcoin wallet such as Electrum. And send him the Bitcoin in his personal wallet instead of any exchange. Also do remember that he knows and aware of the risk involved with Electrum wallet or any other Bitcoin wallet.
Actually wallet software does not set the mining/network fee, they only measure the fee based on an estimation of what it will cost to get transactions confirmed in future blocks. Most wallet software will allow users to set custom mining fee rates, either a specific rate, or a generalized "slow" or "fast" rate based on the above.

This topic about Tor made me test it again. I had to go through 2 sets of Recaptcha (one to register, one for login). That's annoying, but didn't take too long.
What really surprised me, is this:
Quote
Your account contains 19,955.70 units of evil. To atone, you must pay a total of 0.00576923 bitcoins (5.76923 mBTC; 576923 satoshi).
That's $58!
I believe you can actually get around having to pay the full amount by buying a Copper Membership, which currently costs ~$24:
You are automatically whitelisted if you buy a copper membership.
I looked at the thread about Copper Memberships and it is not 100% clear you will have the proxyban lifted if you have a Copper Membership, but I am fairly confident this is true based on:
If you pay the fee, you become a Copper Member, and you can post images.

If the above is correct, it would make sense to cap the evil fees to a percentage of the cost of the Copper Membership. I would speculate the intention was for evil fees to nearly always be cheaper than a Copper Membership, but maybe the price of evil fees was not adjusted when the price of a Copper Membership was.

I don't think it makes much sense to even have evil fees for users who sign up via Tor. All of the Tor exit nodes are public, so if someone signs up with an IP address associated with, or near a Tor exit node, they should be forced to pay a flat fee for signing up via Tor. Evil units should also not accumulate on IP addresses associated with Tor exit nodes when a Tor user is banned. An added benefit to this would be a reduction in noise regarding which IP ranges are a problem with spammers, making spammers easier to deal with because these IP ranges can be more easily detected. 

3335  Other / Politics & Society / Re: Massive Dramatic Hongkong Protest Against Extradition Law on: August 15, 2019, 06:37:04 AM

This is like saying: Why are you so mad that I didn't allow you to speak freely?
The HK government is controlled by Chinese sockpuppets, but there are freedoms available in HK that are not in China. These freedoms attract a lot of capital to HK, which in turn flows into China. For this reason, China cannot invade HK, or otherwise explicitly take over its government without facing serious economic consequences.

The risk for China is that HK turns into a real democracy, and democracy spread into mainland China. This would mean the end of the Chinese government as it exists today.

China's long term goal for HK is to maintain influence over HK via its sockpuppets, however it seems someone got greedy as to how much control they wanted over HK and this has backfired.


An interesting part of the story is that HK protestors are displaying American flags and singing the US national anthem as a symbol of freedom.

What is the purpose of your loan? If for example you are wanting to borrow $10k worth of bitcoin in order to sell it for USD with the hope you can buy the btc back at a lower price (effectively shorting btc), a lender may be able to help you if you are willing to let the lender, or someone you both trust to hold the $5k worth of coin plus the loan proceeds until the loan is repaid. The loan could be repaid with coin from the collateral + loan proceeds.

If you are merely wanting to put up 5 grand to take out a 10 grand loan that you can freely spend on anything, I would find it unlikely any sane lender would be interested in your proposal.
No need to know the purpose. For the purpose, any lender will not change their mind. There is no lender who will give 10k$ loan by taking 5k$ collateral to a newbie. And I think no lender will give 10k$ loan to a newbie by taking 9980$ as collateral.
As I mentioned, the OP could possibly give $5k in collateral in a transaction that resembles a margin trade. The lender would actually be holding onto $15k to secure a $10k loan.

In my experience, almost all of the reports I make that will get handled are handled within 24 hours; I don't keep track, but I would estimate that less than 2% of my handled reports were handled after more than 24 hours. I would guesstimate that over 2/3 of my reports are handled within 8 hours.

I don’t make a lot of reports for sig spam, however if I notice someone making especially poor posts, I will review their post history, and report a handful of their recent posts if they are mostly made up of low effort, or off topic posts, and make a note that the person is wearing a paid signature.

To put this in context, about 2.5% of my reported posts remain unhandled, and less than 1% are marked as bad. I looked at some of my bad reports, and after the fact decided that I probably made a mistake when reporting, and noticed that a moderator action was taken on some others, leading me to believe that someone may have accidentally marked a report as 'bad' even though they took action on it.

I avoided downloading files online using my phone to prevent from getting hack, but hackers now are getting smarter.
This attack has nothing to do with malware or downloading software. It is a social engineering attack that tricks your cell phone carrier into transferring your service to another phone so the attacker can receive your text messages.
Yeah I understand, thanks for clarifying it.

So this is riskier than downloading files in the internet, this one, even if you are online, you can still be victim of hack.
As I have stated, what I only avoid is downloading files online but don't know it's still possible to get hack with the new way of hack shared by OP.
You can avoid the effects of this attack by not using your phone number (receiving a phone call or SMS message) as a means to unlock any financial account. Not as a second factor, and not as a means to reset your password.
3340  Bitcoin / Wallet software / Re: Safest cold storage options currently on: August 15, 2019, 05:24:13 AM
The solution to a $5 wrench attack, and other similar attacks involving physical force to you as a person is to keep a small number of coin associated with a BIP 39 seed with the passphrase/last seed word being something different than the passphrase that secures the majority of your coin. This will allow you to give something to the attacker while both preserving a portion of your coin and maintaining your safety.

Well, but this is only possible if either 1) the person attacking you doesn't know the magnitude of BTC's you own or 2) you have an amount large enough accessible without the passphrase.

If an attacker knows (e.g. because you are telling everyone, or because you are some known person in the community) that you own about X - Y bitcoins, he won't be happy with seeing 1/10 X or even less of that in your non-password protected wallet.
I mean.. you might be able to deceive attacker which aren't familiar with BTC and wallets, but in any other case it will be pretty obvious that the full amount is protected with an additional password.

This might be useful for plausible deniability regarding a person which doesn't know how much you own, but it won't protect you if he knows how much approximately own.
It is a good security practice to not go around bragging how much coin you have. Even if you disregard this best practice, there is always a the chance you are embellishing how much coin you have, cannot remember how to access a portion of the coin for one of many reasons, including due to the stress related to the '$5 wrench' attack.

If an attacker believes you to have 5,000 btc, but is only able to obtain 5 or 10 btc from you, this is still a lot of money, although much less than the millions that would be had from stealing 5,000, and receiving 10 btc might be one reason to deescalate the situation in order to avoid very harsh punishment such as jail time for the attack.   


If someone is willing to torture you for your bitcoin, then it is pretty irrelevant if you have a hardware wallet, airgapped device, paper wallet, or whatever.
The solution to a $5 wrench attack, and other similar attacks involving physical force to you as a person is to keep a small number of coin associated with a BIP 39 seed with the passphrase/last seed word being something different than the passphrase that secures the majority of your coin. This will allow you to give something to the attacker while both preserving a portion of your coin and maintaining your safety.

To answer the OP's question, I would not over complicate my cold storage setup. I would choose a HW wallet manufacturer I am comfortable is making a product that cannot easily be compromised, keep my coin secured by that HW wallet, and use the paper card as a backup with the seed hand written on it stored in a safety deposit box.


The problem of this solution to $5 wrench attack is that it is public, any robber could have read and known that.

IMO, hardware wallet could act as baits. One can simply put two or three shares of coins in a hardware wallet both in dummy wallet and hidden vault(or even plus dummy hidden vault for third share) while put the majority of his coins the rest part elsewhere.
Major HW wallet implementations allow for users to use a passphraise as the last word in their seed, and can potentially have multiple passphraises that create multiple seeds.
