1  Bitcoin / Bitcoin Discussion / In theory there is still another China ban waiting to be launched. on: June 28, 2021, 02:45:49 AM
According to bitnodes and ethernodes, there are around 150 BTC public nodes and 400 ETH public nodes located in China.

CCP hasn't launched an ISP level blockade yet which is one of the few cards reserved in their hands.

Since BTC has 3000+ nodes in TOR (Can't tell how many ETH nodes in TOR) , I think users in China could still have access to full nodes then.

Can someone explain the current decline of node count?
3  Bitcoin / Electrum / Does this kind of wallet generated by electrum word seeds have any flaw? on: April 13, 2021, 03:29:09 AM
I have setuped an offline electrum standard wallet years before(Lagacy one, segwit not supported). I have written down the 12 word seeds as backup.
Days ago, I tried to generate a bipxx standard wallet on electrum by these seeds.
Of coz these electrum 12 word seeds won't match the checksum required by bip39.
So I picked the first 11 words then added another word picked randomly by myself from the bip39 2048 word list. I picked that last word about 20+ times to pick up one just meet the checksum with the first 11 words.
Then I choose 84/0/0 path to generate a bip84 native segwit supported wallet.

So my question is does this wallet generated by above steps have any flaw? (Say, its randomicity or anything else.)
4  Bitcoin / Hardware wallets / I hate hardware wallet being made eye-catching. on: December 25, 2020, 08:48:41 AM
They should not have unique lookings and should not be easily distinguished from other electrical devices.

I don't think it cool but shouting rob me or confiscate my coins to others instead.

I myself prefer, say, a remote control looking hardware wallet with a TV/air conditioner which it can actually control.
Then nobody would doubt it is just a controller.
5  Bitcoin / Electrum / Does android version support message signing? on: December 24, 2020, 07:11:22 AM
I know how to sign a message upon certain address on PC version Electrum.

But my offline signing device is an android phone and I can't find coresponding buttons on android version.

Does it support or not?
6  Other / Politics & Society / Editor-in-Chief of HKFP asked his followers to confront Toby Guu. on: September 29, 2019, 04:16:52 AM

The reason is the latter endangered him. I guess it was done by revealing the other side of some HK protestors.

Toby Guu's youtube channel.

I think this Canadian can't say it is funny any more after receiving quite a few death threats.

Capitalism is shit.CCP is capitalist.

I guess the post is an anarcho-syndicalist or anarcho-socialist.
But he or she can't be an anarcho-capitalist.
8  Bitcoin / Bitcoin Discussion / The Inevitable Consensus Attack on Bitcoin on: August 14, 2019, 02:09:51 AM
1.Bitcoin's vaule is base on consensus.
2.Consensus is reached by all bitcoiners.
3.Mass adoption means so many average Joes will be new bitcoiners in the future.
4.Average Joes are unable,not willing to store and operate their own private keys.They don't even want to learn in the first place.
5.Govts would also educate them that storing your BTC in exchange with some sort of bitlicense is very same as storing BTC all by yourself.
6.That sounds like govt never print fiat more than needed.(Oh they can definately educate people what is need Grin. Deos proper inflaton rate is necessary for good econemy ring a bell?)
7.When most average Joes put BTC in centralised and regulated institutions, govt got the space to manipulate or I'd say tame.
8.At last, new consensus would be built (when average Joes become majority among bitcoiners) that paper BTC in legal exchange is the same as BTC on chain. This consensus would break the 21 million limit so easily without a single line modified in code.(Maybe I should say it already happened since quite a few bitcoiners have chosen the convient way of putting BTC in exchanges.)
9.That is how the god damn govts tamed gold in the past. I don't want this shit happen again on Bitcoin.
10.But since we live on this miserable world, everything we don't want would happen eventually.

How to repel this attack?

BTW:I always think the idea of govts seizing most mining machines then launching 51% attack is so f*cking stupid. Why would they play swords against you when they have an armory consisting from guns to ICBMs at hand?
9  Bitcoin / Armory / Bus error when signing tx of sending coins to other Wallet.(Arm device) on: June 09, 2019, 10:18:28 AM
I use an old cellphone(armv7 cpu) for signing Armory tx. First I installed DeployLinux on it. Then I install Ubuntu 14.04 and serveral dependencies. I did not do crosscompile on desktop devices. I simply compiled the sources on the phone. The process looks successful and I created a wallet(A to refer for convinience). Since last year I have done several consolidations using this device for signing and it worked fine.
     Yesterday I created another wallet. I want to split my funds within two wallets. But when I signed that tx of sending funds from A to new wallet address, the program just crashed, and the terminal background(I didn't install after compiling so everytime I enter Armory through terminal) just show bus error and this is not even recorded in log.
      I tried several times changing addresses and amounts and I found if I sent my coins from wallet A addresses to others not belonging to wallet A, the signing process crashed with bus error. However if I sent from wallet A address to other wallet A addresses, the signing process turned out to be successful. That's exactly how I could be able to do consolidations last year.
      So any ideas about this odd issue? I tried both 0.96.4 and 0.96.5 and no luck.

BTW: Any tutorials about compiling Armory on arm linux devices? I found some but quite old are they.
