1  Bitcoin / Bitcoin Discussion / Blockchain question for Bitcointalk on: January 28, 2020, 09:20:25 AM
Are mutable blockchains, blockchains or databases?

What makes a blockchain "a blockchain", and what makes "a blockchain" a database? Is there a technical answer to it, or is it philosophical?

I have read/listened to many debates about it, but it never arrived to a "correct answer". Is there an actual correct answer?
2  Bitcoin / Bitcoin Discussion / Peter Schiff's Bitcoin wallet mystery is solved on: January 23, 2020, 06:35:12 AM
Plus surprise, it isn't Bitcoin's fault, which at first was "Bitcoin's fault" as he was trying to indirectly suggest. He's now probably trying to save his reputation because he only made himself look stupid.


My #Bitcoin mystery is solved. I mistook my pin for my password. When Blockchain updated their app I got logged out. I tired logging back in using my pin, which was the only "password" I had ever known or used. I also never had a copy of my seed phrase. Honest but costly mistake!

3  Bitcoin / Bitcoin Discussion / Nick Szabo on successful Bitcoin HODLERS on: January 22, 2020, 11:01:14 AM
Words straight from the man who is highly regarded as the "might be" Satoshi Nakamoto. Cool

Don't listen to the FUD, and let the numbers/facts guide you. From that, you know what to do, Buy the dip and?


Successful Bitcoin holders have low time preference & judge over extended periods, e.g. risk-adjusted return over 4-year holding periods. If an economist has not researched this strong market signal for explanations of supply & demand, they don't have a useful opinion about it.

4  Alternate cryptocurrencies / Altcoin Discussion / Proof of Stake technical dicussion on: January 17, 2020, 06:11:39 AM
Long-range/nothing-at-stake attacks are known vulnerabilities in Proof of Stake, and the known solution is to rely on third-party checkpoints.

Someone sent me a PM that told me, "no, not necessarily, because long-range attacks are blocked by coin age".

I will quote the message, but removing the name of the coin, and keep it strictly technical. I'm not a very technical person, I need your help. In fact, I'm the stupid one in the forum.

His/her message,


Long Range attacks against ---'s design of PoS are blocked by the coin age.

Unlike bitcoin where miners hold the same % control of mining.

In ---'s PoS everytime you stake your % Drops for a specified length of time.

Sustained Long Range History attacks are blocked by the dormancy feature.

Collusion in Proof of Stake would mean actually giving your coins to a 3rd party , as such they could just sell your coins for fiat and leave you holding nothing.

If --- Stakers did ever collude , they destroyed all of the money they used to buy zeitcoins.
There are no other networks for them to jump too, that preserved their initial investment.

5  Bitcoin / Electrum / Lightning on Electrum updates? on: December 29, 2019, 11:35:53 AM
The last news I heard was that Lightning features would be out "on the next release". Does anyone have new updates?

Will Electrum be looking for alpha/beta testers? Cool
6  Bitcoin / Bitcoin Discussion / Is Bitcoin immune vs. central bank schemes? on: December 16, 2019, 06:53:53 AM
Listen to their speeches in this short video. I believe I see a Bitcoiner - gold-bug parallel

Will Bitcoin be next in the world's central banks' schemes? Is it unavoidable that Bitcoin will also be "economically censored"?
7  Bitcoin / Bitcoin Discussion / Andreas Antonopolous speaking about nation-states theoretical attack on Bitcoin on: November 25, 2019, 05:42:48 AM
I have never been more confident in Bitcoin, POW, and its working incentive-structure after listening to this talk by Andreas.

Don't be trolled. Cool

I found a thorough software wallet analysis from,

Here's a link to the table presenting all known wallets,

Post mistakes and disagreements, if there are any.

9  Bitcoin / Bitcoin Discussion / He's thankful he found "Bitcoin" on: October 21, 2019, 05:53:27 AM
Hahaha! Scammed.

But on a serious note, this is what happens when trolls/liars/propagandists reach the the people who are early on their journey.

It's YOUR responsibility to give them the truth, and put them on the correct path.


I truly appreciate Pham. My goal was to acquire 1 $BTC by the end of the year, and thanks to you I found out about $BSV, and now own about 15 BitCoin. My new goal is 30 BitCoin by 12/31/2019.

10  Bitcoin / Bitcoin Discussion / Shower thought. If nations/states/governments are accumulating Bitcoin, then on: September 17, 2019, 06:49:35 AM
I believe they must be doing it in secret. What would be the advantage for North Korea, or Iran, to let everyone know that they are accumulating/mining/HODLING?
11  Bitcoin / Bitcoin Discussion / Shower thought. Bitcoin ETF bad? on: September 09, 2019, 08:29:57 AM
Shouldn't the communty discourage the creation of anything that gives up the custody of Bitcoin to third parties?

Although it might be good for its price, would it be good for Bitcoin as a censorship-resistant hard money?
12  Bitcoin / Bitcoin Discussion / Bitcoiners in Hong Kong protests? on: September 04, 2019, 09:24:26 AM
Are there Bitcoiners in Hong Kong? How is the situation over there? I believe it should be Bitcoin's time, and help protesters in collecting donations, and help move value in Bitcoin.

Happy 2nd anniversary, Segwit.

15  Bitcoin / Bitcoin Discussion / A page from the book "The Sovereign Individual", 1998 on: July 30, 2019, 05:35:09 AM
It's so uncanny how accurate this describes Bitcoin before Bitcoin was invented. Lucky for us, that future is today, and there's no other way to win the game, but to play. Buy Bitcoin!

16  Bitcoin / Bitcoin Discussion / The biggest battle for Bitcoin's life is coming on: July 17, 2019, 05:48:51 AM
I hope everyone is ready for it, because it's going to be the biggest test in your HODLING abilities, and resolve.

What would transpire is the biggest socio-political/socio-psychological attack that the community would ever see, and it would involve state-level actors/governments.

Prepare yourselves. It's coming.
17  Bitcoin / Electrum / PSA: New phishing attempt on: June 29, 2019, 07:55:23 AM
Be careful electrum users/newbies. Scammers, hackers, and thieves are becoming more active because of the new Bitcoin rally.

You are all targets, especially newbies.


Do you see that little fleck of dust under the domain name in the left screenshot? Actually not dust. Enable show_punycode in Firefox in order to avoid phishing URLs.

18  Bitcoin / Bitcoin Discussion / PSA: Firefox zero-day exploit used to attack Coinbase. Update Firefox on: June 21, 2019, 06:14:52 AM
Coinbase employees were the target, but as Bitcoiner, you could also be a target, especially if you use the same computer for Bitcoin and for everything else.

Update Firefox, install Noscript add-on.


So like 90% of browser zero days, it's all about javascript.

Meaning, if you ran noscript or umatrix you'd be safe from most of the sites that would potentially host a harmful script to you.

19  Alternate cryptocurrencies / Altcoin Discussion / This will not work how the creators' had planned on: June 16, 2019, 08:44:27 AM
Can transaction fees also be payable in BTC2 tokens? I believe that might cause some trouble in their network.

Ask yourself which transactions would the miners mine first. Fees paid in BTC2, or fees paid in BCH? Cool


BTC2 is a token on the #BitcoinCash blockchain (using SLP tech) that is 1:1 backed by on-chain BTC.

BTC2 is like USDT. As USDT is an IOU for USD where Tether holds the actual USD in their bank, @sideshiftai is the custodian of the on-chain BTC and issues BTC2 tokens in return.

20  Bitcoin / Bitcoin Discussion / Jihan Wu and his Bitcoin OTC trading desk on: June 07, 2019, 11:08:13 AM
Shower thought. What if it was made to sell all of his and/or Bitmain's billions held in Bitcoin Cash to unsuspecting fiat whales. Cool
