The bitcoin mempool is where unconfirmed Bitcoin transactions are stored.
It's a set of all all the transactions that have been broadcast but have not yet been added to a block by a miner.
Every node has its own transaction relay policy so there is no definite mempool, but different mempools for different nodes.

1243  Bitcoin / Development & Technical Discussion / Re: What is use of Checkpoints in a cryptocurrency? on: October 12, 2018, 06:02:53 AM
Most importantly on a wider sense, checkpoints were implemented in the bitcoin code for preventing DOS attacks to happen in the network and to prevent the miner to take control of the network and perform the 51% attack successfully. The checkpoints prevent the miner (attacker) to hash the block in a lower difficulty. Thus satoshi introduced checkpoints in each and every version of the client released after 0.3.1. Here is the announcement of the checkpoint

- Added a simple security safeguard that locks-in the block chain up to this point.
The security safeguard makes it so even if someone does have more than 50% of the network's CPU power, they can't try to go back and redo the block chain before yesterday.  (if you have this update)

I'll probably put a checkpoint in each version from now on.  Once the software has settled what the widely accepted block chain is, there's no point in leaving open the unwanted non-zero possibility of revision months later.

For instance let us consider how the network functions without the use of checkpoints. A miner might have mined a block in a low difficulty earlier period and relayed it to the network. The block becomes part of the longest chain and without the use of checkpoint, the miner will try to mine the future block in low difficulty. The miner can even make us listen to the fake difficulty chain. If there is a checkpoint, the miner need lots of mining power to continue mining the longest chain.

In simple terms, the checkpoints are coded each time with current difficulty when the client gets a new update so that the client will accept transactions as valid only up-to the checkpoint. This also prevents the fork of the coin to start before the checkpoint specified block.

But as days passed by, these checkpoints were not really helpful nor they provided any real security and they created confusions. Thus the core devs stopped providing checkpoints in the future releases of the client, and if any nodes see a block they consider it as checkpoint and the future blocks below that height would be considered invalid.

There was a similar case which happened back in June. A group of scammers/spammers started promoting a shit and a proven shady exchange with their spams. They were around 5-10 members who constantly promoted their exchange through their spams and were posting irrelevant shits praising their exchange in most of the topics. Each posted around 5 posts about the exchange in random various threads with the total coming around 20-25 posts per day. I guess I was the sole reporter who were reporting their posts for quite few days. Neither they were banned nor they were tagged during this period. The reports were handled only after 3-4 days of active reporting. After 2 months of instant reporting most of them were banned last month. Thus it takes time for them to get banned or tagged by DT or MOD.
1245  Alternate cryptocurrencies / Altcoin Discussion / Re: Altcoin branch of Litecoin 16.3 creates new addresses but has no private key on: October 10, 2018, 07:54:53 PM
  Then I go to the console and type "dumpprivkey <address>" and it responds with "Private key for address <address> is not known".
The function is returned as "private key not found" only when you type the dumpprivkey in console while the wallet is locked. You need to unlock your qt wallet before typing the dumpprivkey in the console. You can unlock your wallet by typing

Code:
walletpassphrase "passphrase" [unlock time in sec]

Once after this function has been executed, you can proceed with dumpprivkey [address] which will give you the private key of the address. 

Note that regarding tracking of transactions, consider my previous reply on your earlier thread to use the --rescan function.
1246  Alternate cryptocurrencies / Altcoin Discussion / Re: Altcoin branch of Litecoin 16.3 won't show transactions on: October 10, 2018, 06:53:25 AM
Try restarting the wallet via cmd. While restarting type --rescan in cmd so that the wallet would re-compute almost all the transactions and would display the new updated balances. I need few details so that I can figure out where have you gone wrong

[1] Are the coins showing up in another wallet? Since you have said you sent coins from another wallet, does that mean have you mined some coins to another wallet and are those coins showing up in that another wallet?

Litecoin official core wallet automatically rescans the portion of the blockchain and shows updated balances from time to time.

What parts of the code could produce and or affect this result?
I am not really good in the code, but let me try to explain how flow works...

Suppose you are the one who creates the Block and adds transaction to them using CreateNewBlock class. Once you have solved the block, the coinbase transaction looks for the scriptPubKey parameter of the class and sends you the generated coins.

For you to get paid by coinbase transaction, the code is present in miner.cpp file I guess. I am not really sure about it  Tongue

Code:
// Create coinbase transaction.
    CMutableTransaction coinbaseTx;
    coinbaseTx.vin.resize(1);
    coinbaseTx.vin[0].prevout.SetNull();
    coinbaseTx.vout.resize(1);
    coinbaseTx.vout[0].scriptPubKey = scriptPubKeyIn;
    coinbaseTx.vout[0].nValue = nFees + GetBlockSubsidy(nHeight, chainparams.GetConsensus());
    coinbaseTx.vin[0].scriptSig = CScript() << nHeight << OP_0;
    pblock->vtx[0] = MakeTransactionRef(std::move(coinbaseTx));
    pblocktemplate->vchCoinbaseCommitment = GenerateCoinbaseCommitment(*pblock, pindexPrev, chainparams.GetConsensus());
    pblocktemplate->vTxFees[0] = -nFees;

    LogPrintf("CreateNewBlock(): block weight: %u txs: %u fees: %ld sigops %d\n", GetBlockWeight(*pblock), nBlockTx, nFees, nBlockSigOpsCost);
1247  Bitcoin / Wallet software / Re: Currently Best Means of Offline Storage? on: October 05, 2018, 07:05:51 PM
I have had some crypto on exchanges longer than I'd like.
Do you really need another mt.Gox shit to take place in your life? Trusting exchanges is really bad, there may be literally very high risks associated with the exchanges holding your coins. Just move out your coins and hold only which you are trading currently.

I'm wondering what the best means of storage currently are since I haven't been paying attention much this year.
For offline/cold storage is it still a debate between paper wallets (very annoying to setup) and the ledger nano S?
It would be good if you store your coins offline. Some of the secure storage options include

[1] Buying a good hardware wallet like Trezor, Ledger or Keepkey. You can better stick to any of these 3 hard wallets.
 
[2] Creating a paper wallet if you are really aware what you are doing and have a basic knowledge on how a paper wallet works. Spending from a paper wallet quite often is really a very tedious job which may lose one's interest in them.

[3] Creating an offline environment for storing your coins securely. You can do this by buying a cheap laptop and never connecting them to network. Download Electrum from a online computer and securely move them to a offline one and store them. You can even create a multisig wallet so that it needs atleast 2 persons to sign the transaction to release the funds. Electrum offers a wide range of hard wallets support and you can integrate almost all the above mentioned hard wallet with your Electrum wallet. In order to track the funds, you can create a watch only wallet in any of your online PC or Mobile

I want to store these long term. However, I worry about the Ledger because it is still operated through a third-party. I also dislike paper wallets because the process is so tedious and a hassle; especially for multiple coins.
Hard Wallets would be safe until you generate the seeds yourselves. There needs to be trust among anyone doing a good job for the past years. If you don't believe anyone, better stick to the paper wallet and generate them by flipping a coin or a die. Ledger is an open source project as suggested by OmegaStarScream but the firmware itself is not an open source.

Newbie atithisha seems to be posting plagiarism content from various sources for promoting their platform. I have reported their post 2 days back for plagiarism and for necro-bumping a 2 year old thread, but those reports are still un-handled by mods.

Smart Contract solutions are a revolutionary blockchain application. What they do, essentially, is to secure the fulfillment of a contract without having to get any third party involved.

There is an extreme amount of excitement around blockchain projects for investment, innovation, and development. ICOs can be done by anyone with a few bucks and a few hours. A successful, sustainable smart contract will cost more and take longer, but the process is still significantly faster and cheaper.

Note that you are advertising an ERC20 token(BQT) in your signature.
I am fully aware about that. For your information this campaign reward is by btc and this is spam free campaign as well there is merit required. You are ignoring my point, award should be by bitcoin. So participant no need to worry about exit scam except investors.
I will disagree with your point. I am aware about the campaign rewards being paid in Btc and it is being run by Zapo as I was a part of similar campaign run by them. Participants are mere advertisers and promoters/ marketers of the product. There might be a newbie investor who view this signature and might invest in the project with little read through of the white paper. I have seen some DT negging some bounty hunters who promote the scam even after the projects were exposed. Both Participants and managers who promote the project should be aware of the project they are endorsing so that it doesn't misguide any newbie investor who enter this field.

How you consider bitcoin is a ponzi scheme, there are no promising return. How new investors are lost money ? Someones scam them ? There is any promising high return on bitcoin whitepaper ?
I agree with this solely. FYI Dick bigs a Ponzi is something where the people/group of people urge others to invest in their companies or so called great returns schemes. Also a ponzi scheme owner promises gains if the people invest in their company. Did satoshi ever say anyone to invest in bitcoin? Was it even worth enough to buy few thousands of btc for a $ in late 2009? If you/anyone who say btc is a ponzi it clearly states that you doesn't even understand what a ponzi is! You are not urged by anyone to invest in btc nor satoshi didn't run away with the money as commonly ICO owners does!
1250  Alternate cryptocurrencies / Altcoin Discussion / Re: CryptoNote android wallet on: September 30, 2018, 06:39:25 PM
but none is working for my coin or its closed source.....
Is your coin a fork of monero or simply a coin based on the cryptonote technology? If the source code of a coin is not open,  then it's a might be a scam or may be a shitcoin.
Bytecoin is based on the cryptonote technology and it has a android wallet of its own I guess.

monerujo seems to be an alternative to the Monero core wallet and it has an android version too. But trusting a third party wallet for storing your coins should only be at your sole discretion. Hence, it would be better to stick with the core wallet to store your coins.

Entertainment section
There is already a section "Off-Topic" for discussing games and other stuffs that are not related to cryptocurrency. Moreover this is a crypto forum. We come here only for learning and discussing crypto related stuffs. There are a lot more forums out there for other purposes. This is not a generalized discussion forum to have a board for each and every thing we encounter in our life. Gaining activity for no reasons seems to be common here. If such a board is created it would get trashed similar to the Off Topic Board. This won't cause the reduction of spam rather it would increase on a larger scale.

Gambling Section
Have you even checked out all the boards of this forum? If you had checked, you would have seen a dedicated Gambling Board for Gambling Discussion to take place. Good profit? The forum already has lots of reserves which will keep the forum running without losses for long time. Forum ads, 10Btc and 50Btc Donations which were made long back is still helping the forum as said by theymos.

VIP section
There is a separate board for Donators to discuss which cannot be accessed or seen by normal users like us unless we donate 10Btc to the forum.

Local Boards
There are already a lot of ton of local boards. Aren't you one among the boards? If you need a separate board, you can always request for it here in Meta.

All of this are not really that necessary but if other members will agree with this then I will appreciate it.
All the boards you requested are already present here. If you have already gone through the forum you would have not created this topic.

Bitcontalk.org forum is far more better and thus I would like for bitcointalk.org to continue on the improvement. As a member of the forum I would like to see some improvements or even monopolize other forums as well.
Patiently wait for the new forum software till 2020-2021. That would be one of the most expensive discussion forum ever developed with a budget of 6900-10000 Btc (Though I am not pretty sure) and almost 6+ years in development. I assume the final product would be jaw-dropping when it goes live. If you had been actively watching the development, you would have seen the beta version which was live for a couple of months.

Best option for me if required Bitcoin for bounty campaign. ERC-20 is useless until it listed on reputed exchange.
Note that you are advertising an ERC20 token(BQT) in your signature.
What makes you say so that ERC20 is useless? EOS was an ERC20, BnB is an ERC20. Both of them weren't traded in reputed exchanges at first. Many even thought that BnB along with its exchange would fail miserably.
Does that mean they are useless?
Listing in a reputed exchange alone won't make the token/coin great enough to be accepted as a legit one. Are you exactly against tokens or the scams and spams happening around the forum? If you are against alts stop advertising ERC20 in your signature.

Since this is Bitcoin forum so forum could require Bitcoin for bounty award.
No, this is no more a bitcoin forum. This is one of the largest cryptocurrency forums. If this is a btc forum, then why does it have "Alt currencies board and why do they allow ANN of alts?"

Regarding your guidelines, they are already being followed by some of the reputed and spam free managers.

1254  Bitcoin / Development & Technical Discussion / Re: Brainstorming on: September 27, 2018, 05:20:04 PM
Idea 1: a system of notatization with backup or not for docsdocs ... With C2C service and B2C/B one even a government to Citizen service...
What do you mean by notatization? I have never heard something like this before  Huh If you meant notarization of a document by the usage of a digital signature, it's literally a good idea to think. But your question is not pretty clear to be answered. Consider that we need to digitally verify the signature of a person, we can do that by the usage of possible pubkey of the person. This particular kind of actions can be performed with coding of a proper smart contract. Smart Contracts can be very useful in carrying out such types of validation practices. Smart Contracts can be better coded in the Ethereum Platform with the establishment of your own token. Let us assume that we have coded the Smart Contract in the Ethereum Platform, the contract serves as the central middle-man between the C2C or B2C as you have said for validating the signatures of the other person.

Idea 2: a "meal voucher" project ... I let you develop because the stakes and constraints seem obvious to me ...
Your ideas seems to be really interesting, in the sense if they are carved out properly. Let us consider that you start up your own company and you offer some meal vouchers for your employees. In this case, these vouchers can be ERC-20 tokens. Consider tying up with some restaurants and buy back the tokens which were given by your employees to the restaurants for meal. In simple terms the flow can be like, the smart contract by default gives away some meal tokens to your employees in their wallets. They spend up their tokens by buying some food in particular restaurants. They send the tokens to the restaurant which further the restaurant can redeem from your site to their fiat money. You don't need a pay-roll or any team to order these vouchers, everything can be handled up by the contracts.

P.S I am not sure of how these ideas can be flourished with the help of ada or stellar as I have never used them. Also I think this don't seem to be a Tech Discussion in Btc section...

Here is the ANN Thread : https://bitcointalk.org/index.php?topic=5030366.0
Merit can be earned by posting informative posts in order for you to become a Jr.Member. If you are not really a great poster and need the rank only for joining bounties, you can buy a Copper Membership from here : https://bitcointalk.org/index.php?action=credit;promote
ANN Thread for buying a Copper Membership : https://bitcointalk.org/index.php?topic=2385104.0

Going through your posts, you have participated in large number of bounties and paying 0.002BTC for copper membership is not a great deal. Buying a copper membership can help you

[1] To wear Signatures equivalent to a member.
[2] Add Images to your posts.

Bullshit. You account is older than mine by 6 days considering the day of registration.  Angry
Posting quality isn't determined by the length of the post, it is determined by how helpful they are. Almost all your shit posts are in spam mega threads and  none of them contribute to the discussion nor it hasn't helped at least 1 member. Your knowledge is equivalent to zero in crypto considering the shitposts you have made so far. Stop posting in Altcoin Discussion and try to gain some knowledge in quality posting so that you may receive a single merit before you fade out completely.

Isn't it easier to get a single merit through merit abuse? Though 1 merit rank up to Jr has been long discussed by members around here, that doesn't end the spam I guess.
At least 5 merit requirement would be very hard to rank up to Jr.

I believe that bounty spamming restrictions should be placed on all new and junior members.
This might be a possible solution to think off.

1259  Alternate cryptocurrencies / Altcoin Discussion / Re: Information about ZCL fork on: September 14, 2018, 03:56:37 PM
It's good that you had started a self Mod thread, otherwise it would have been spammed to the core with bull shit replies with people not even knowing what is a fork after all.  Tongue

Actually ZCL not looking good right now, reflects the whole altcoin market. ANON did not have any positive impact.
But the chart may show that right now is the time to buy for a profit in the middle term. Being speculative here obviously...
I was lucky enough to grab some zcl 2 days before the snapshot took place. I bought something around 30 zcl coins though I never gave a read on what really was zcl before. 30 coins was around 0.027BTC and I received 60 anon via airdrop.  This was a speculative investment where I was ready to lose my investment though I have never done something like this before. I literally take around 3 weeks to read and understand the coin completely before investing my bucks. Anon is currently trading at $1.8 which gave me $110 and 30 zcl gave me $110. Now I am in a safer area with a profit of $45. Though it's not really a great return, but getting $45 in a week is good according to me.

Zcl most probably tanked due to the fork and may regain it's price with some minor improvements in it's blockchain. Though I am not literally sure about this. For instance, let us assume Btc was trading at $2000 when Bch forking happened. Bch started its trading at $100 and eventually Btc will tank by $100 and the final price may be $1900. This is how a price of a coin is determined after forking takes place. I may not be selling my zcl and anon until I receive 2x of the btc I invested unless and otherwise there is really a need of fiat for my expenses.
1260  Alternate cryptocurrencies / Altcoin Discussion / Re: Information about ZCL fork on: September 12, 2018, 07:53:34 PM
The fork is a combination of both the ZClassic and Bitcoin. The devs of the new fork coin are using the technology of the btc blockchain and the anonymity feature of ZClassic. Hence each bitcoin holder receives 1 Anon and each Zcl holder receives 2 Anon. The snapshot was taken on September 10 and the mainnet went live from today. We would be knowing about the exchanges only later this week.

Not all the exchanges supported the fork and only certain exchanges which were mentioned are where the forking snapshot took place. We need to see how the fork plays out, since ZCash got split from Btc and BTCP splitted from ZCash and btc blockchain. ZCl splitted up from the BTCP Blockchain and Anon splitted from the Zcl and Btc blockchain.
