1001  Bitcoin / Development & Technical Discussion / Re: Lightning Network releases Mainnet support for Bitcoin and Litecoin on: March 17, 2018, 06:08:26 PM
People shouldn't forget that LN is still in beta (even though Bitcoin considered still in beta version) and as far as i know, the setting/configuration for using LN isn't as friendly as using mobile wallet.

it's a big news. but the market is bearlish.

Even SegWit which reduce tx size, indirectly increase maximum block size (2MB - close to 4MB) and hyped even by mainstream news don't have much impact Roll Eyes

For non-technical/savvy people, i only can recommend Simply Explained - Savjee channel. Shouldn't be too hard since even novice programmer can understand it Smiley

This book is probably one of the best resources for learning about bitcoin and the blockchain in my opinion.
"Antonopoulos A. M. - Mastering Bitcoin - Programming the open blockchain"

I haven't reached chapter 7 yet which talks about the blockchain, but all the preceding chapters about
keys, addresses, wallets, transactions, etc, have been great.


Thanks for the book, I will read it.

Make sure you read the 2nd edition since it covers more info such as SegWit.

If you don't want spend money or prefer books, then i'd suggest you to check these lists (even thought i only read few book of it) :
https://github.com/decrypto-org/blockchain-papers
https://github.com/coderplex/awesome-blockchain

If you're interested in specific cryptocurrency topic,  you should check Mastering Bitcoin, 2nd Edition.  Programming the Open Blockchain by Andreas Antonopoulos and these lists :
https://github.com/igorbarinov/awesome-bitcoin
https://github.com/Scanate/EthList
https://github.com/jashmenn/bitcoin-reading-list

For basic/starter video, i'd recommend Simply Explained - Savjee channel which explain thing extremely simple that novice programmer can understand.

Not bad idea, but what'll you do when the users want to invest on Cryptocurrency which have high network fees ($0.1 or more) ?

Also, how about the legality of buying cryptocurrency with Credit/Debit card since it's not allowed in some country ?
1005  Bitcoin / Bitcoin Discussion / Re: How to stay safe from bitcoin theives on: March 16, 2018, 04:51:44 PM
1. Never keep your bitcoin in exchange or centralized wallet.
2. Always use secure connection and check website's credibility if you're using online wallet
3. If you're using desktop/mobile wallet, make sure the device is clean and you download the wallet from genuine website.
4. Use Hardware Wallet and buy from official website/seller. Some fake/malicious hardware wallet comes with it's mnemonic seed.

While multi-signature address is good way to secure bitcoin, it's not really convenient and the transaction size is bigger.

--snip--
  • Read the source code.

Not really good advice since only developer or those with programming knowledge can "review" the source code.
1006  Bitcoin / Development & Technical Discussion / Re: How did you learn blockchain development? on: March 16, 2018, 04:27:18 PM
Here's list of books about BTC/ETH/Blockchain with categorization of specific topics that might interest you :
https://github.com/decrypto-org/blockchain-papers
https://github.com/coderplex/awesome-blockchain
https://github.com/igorbarinov/awesome-bitcoin
https://github.com/Scanate/EthList
https://github.com/jashmenn/bitcoin-reading-list

But since you specifically mention something similar with Bitcoin, Mastering Bitcoin, 2nd Edition is perfect for you. Detailed topics, but even novice developer can understand it.
1007  Bitcoin / Bitcoin Discussion / Re: Bitcoin Anonymity on: March 16, 2018, 04:15:02 PM
  • You can check the transactions confirmation and other information such as the quantity of bitcoin you've send or received.

If you're the sender/receiver, you can check it anytime whether the coin that you use transparent blockchain such as Bitcoin or private one such as Monero.

  • You can use it as evidence that you already paid or received.

True, but not really useful if the buyer/seller have intention to scam.

  • Incase you've been scammed you can track him. (But you it needs a lot of work)

Simply knowing the bitcoin movement won't help since you won't able to get it back without professional/police help, even worse if the scammer use Bitcoin mixer.

  • They can track you using your transactions via Blockchain

True, but as long as all of your bitcoin address which involved isn't connected to your identity/account, you should be safe. Bitcoin mixer also help.

  • The transaction is not that much anonymous

Again, only when bitcoin address which involved isn't connected to your identity/account.
1008  Bitcoin / Bitcoin Discussion / Re: Future of P2PKH on: March 16, 2018, 04:02:34 PM
P2PKH/Legacy address don't have place in future if bitcoin community move forward with newer technology, but surely it's slow process just like moving from IPv4 to IPv6 Roll Eyes
Also, i'm sure future technology/update won't support P2PKH/Legacy address. Even LN now drop support for P2PKH/Legacy address.
1009  Alternate cryptocurrencies / Altcoin Discussion / Re: how to create your own token on: March 15, 2018, 12:16:14 PM
If your reason don't want use ERC20 because you have no idea how to make ERC20 token, there are websites which let you make your own ERC20 token easily (such as https://coinlaunch.market/coincreator/) without any Solidity programming knowledge.
Also, without those platform, that means you need to create your own smart contract about token and it's behavior. But there many tutorial about ETH smart contract such as https://hackernoon.com/comparison-of-smart-contract-platforms-2796e34673b7

If you still don't sure which smart-contract platform/cryptocurrency you want to use, you can check this comparison at https://hackernoon.com/comparison-of-smart-contract-platforms-2796e34673b7

We already know that disable signature or limit signature usage (far less character, no background/color) are effective solutions Roll Eyes
You also can check "Development & Technical Discussion" and "Serious discussion" even though there's not too much thread/reply.
1011  Other / Meta / Re: Is Bitcointalk a Deeponion forum? 【list updated】 on: March 15, 2018, 11:57:05 AM
If your local moderator won't do anything, get list of spammer who use word 洋葱, Onion or DeepOnion and share the list here so global moderator/admin can ban and member can add these spammer to ignore list.
1012  Bitcoin / Development & Technical Discussion / Re: connect two bitcoin core nodes on different machine, using regtest on: March 15, 2018, 03:58:52 AM
If i'm right you should add -daemon parameter when you running the bitcoind and make sure the firewall lets you open port 18332 or bitcoind is allowed to established connection.
If you haven't configure the bitcoin.conf, maybe that's the problem Roll Eyes
1013  Alternate cryptocurrencies / Altcoin Discussion / Re: Boolberry V2: Efficient Compact Decentralized Anonymous Payments via Ring Sigs on: March 14, 2018, 05:05:07 PM

It's not bad idea to cut Ring Signature from calculating TX ID, but do you think it's possible to combine Schnorr Signature with Ring Signature to reduce overall input/decoy size in transaction?

Hi ETFbitcoin,

That is an interesting concept, combining Schnorr Signature with ring signatures is possible although it would require further study to observe the cost benefit analysis. Herranz et al. proposed such a system in their 2003 ePrint: "Forking Lemmas in the Ring Signatures' Scenario" however that system is still linear.

Hi ETFbitcoin,

Upon further study: a transaction in our system employs (linkable) ring signatures in two different places. On one side, the sender signs his transaction with the linkable ring signature scheme. On the other side, a ring signature is required in the process of proof-of-sum. If one of them is replaced by Schnorr's signature, the anonymity of the whole system will be decreased. Moreover, Boolberry uses a special flag [2] to guarantees that a coin won't be spent without mixins. Such a technique is to deal with the problem caused by signing a transaction on behalf of a ring with only one participant. Since the Schnorr's signature can be regarded as a ring signature with one participant, we don't recommend combining it with ring signatures in Boolberry v2.

[1] - https://eprint.iacr.org/2017/921
[2] - https://www.slideshare.net/boolberry/boolberry-solves-cryptonoteflaws-37055246

That's unexpected since Schnorr Signature can increase privacy when it's combined with non-privacy coins (everyone can see sender,receiver and the amount) when there's more an input, but thanks for the info.
1014  Other / Meta / Re: Introduce a "Up vote & Down vote" system instead of the "Merit" system on: March 14, 2018, 10:05:16 AM
Add "Up vote & Down vote" feature, then we will see r/bitcoin and r/btc sub-Reddit "quality" posts here. Even only add "Up vote" feature still can be heavily abused.
1015  Other / Meta / Re: Suggestion: Merit Phase 2 - Drain the Swamp (@theymos) on: March 14, 2018, 10:01:48 AM
Not bad idea, but i think it's too complicated. Disable signature or limit signature usage (far less character, no background/color) is more effective.

1017  Other / Meta / Re: Suggestion: Raise merit requirements at the lower and highest ranks (@theymos) on: March 13, 2018, 05:45:47 PM
If signature is disabled or extremely limited (far less character or no background/image color allowed), surely only few people would complain this suggestion Roll Eyes
But i agree the minimum merit for Hero/Legendary is a too high, considering not everyone can have popularity/attention/good reputation and not everyone give merits depending on writing/info quality, some even give merits to those they know well.
1018  Bitcoin / Bitcoin Discussion / Re: Do you think twice before paying with Bitcoin? on: March 13, 2018, 05:34:34 PM
No, since using Bitcoin as currency is illegal in my country and the company/services who disobey that will face legal/law problems. But i still use Bitcoin as payment method/currency when i buy something form international seller for digital goods and it's difficult to use bank/credit card for international transaction anyway.
1019  Bitcoin / Development & Technical Discussion / Re: Which is the best in transactions? on: March 13, 2018, 05:28:42 PM
If your concern is only about fast confirmation and low fees, both Bitcoin & Bcash are bad compared with DAG/Tangle-based coins which have extremely low fees.

Bitcoin Cash (hard fork) is a result of a prolonged disagreement on how to handle the bitcoin scalability problem. A group of people not content with the new Segregated Witness feature decided to increase bitcoin transaction capacity eight times, on a different blockchain without it[1].
BitCoin Cash is an escape from the problem(scalability problem) and not solution.

Up to now scalability is not a big problem so there is no need for Bitcoin Cash (Bitcoin won Grin)Perhaps Roger Ver  has another conception.

In the future, the following solutions are feasible:

  • LN payments: bi-directional payment channels which allows payments to be securely routed across multiple peer-to-peer payment channels.[2]
  • federated sidechains:don’t require any changes to the Bitcoin consensus rules. Merged-mined sidechains, which have not been implemented yet, do require a backwards-compatible soft fork in order to transfer funds between Bitcoin and the sidechain.[3]
  • hub-and-spoke:is a form of transport topology optimization in which traffic routes are organized as a series of 'spokes' that connect outlying points to a central 'hub.' [4]

True, but there few additional info :
1. Bcash transaction capacity isn't 8 times since Bitcoin now use SegWit and block weight (not block size) limit which makes transaction size smaller while increasing maximum block size indirectly (about 2MB - slightly less than 4MB if all transaction use SegWit).
2. Other technology such as Schnorr Signature (less transaction size with better privacy), MAST (reduce script size in transaction size with better privacy) and Simplicity (basically more-efficient non-turing complete scripting for Bitcoin transaction) also can be considered as solution for scaling problem.

--snip--
I can't name one merchant or user I transact with that would accept BCH. Even piratebay laughs off BCH donations.

Like it or not, i've seen more merchants accept Bcash, especially due to BitPay accept Bcash while promoting Bcash have lower "Network Cost". Even though the number of merchants which accept BTC is far bigger.

Edit : I found this link on reddit https://acceptbitcoin.cash, but i'm not sure the list is true/accurate.
1020  Bitcoin / Bitcoin Technical Support / Re: Does adding nodes in Bitcoin core increase its speed? on: March 13, 2018, 04:59:49 PM
Post above me already explain most possible reason, but i think Background process/user application sometimes can reduce performance (especially on Windows OS). Also, make sure your system don't limit CPU/internet usage for Background process/user application after the screen is turned off or user is away after specific time.
Update your driver/BIOS might help a bit, even though most user won't notice the difference.

Wow, with 0.22% every hour... I can see this as being a huge barrier to BTC adoption by normal people.

It's probably why people resort to using hardware wallets, like Trezor, or online web wallets.

But, I guess in the same token... if Bitcoin is to be used as a banking alternative, with utmost security... then it only makes sense that high tech specs are required by someone's computer in order to integrate the "banking system" with their computer. Minimum of 150 GB lol.

I guess that means in the future you'll have a computer that's solely for bitcoin purposes, which is more secure in the long run.

I agree with the others, it's not about the nodes, but rather your computer's specs. It's 150 GB that your hard drive has to validate via processors and such. Not going to be a lightning fast process... but once it's done, you'll finally have bitcoin core running and you can make cold wallets and everything. Smiley

Regular user don't need to run full nodes, use SPV wallet while connect to multiple nodes (to prevent get manipulated info by specific nodes) and use Bloom filter (prevent nodes know which address,TX id or UXTO info that you really need) will do just fine.
Only services, exchanges, miners or people with lots of security/privacy concern who would want to run full nodes.
