What exactly happened though?
Did a miner see your plea here on /Bitcoin and included it?
Or did you broadcast it specifically to a miner (i.e., pushtx)?
Or was the original fee just too low to be relayed by nodes, so the replacement transaction (with the higher fee) was effectively the first transaction seen by a peer node which then relayed it?
Or is Full RBF out there on enough nodes and somehow this transaction got relayed to a miner that has implemented Full RBF?
Or ????

"My transaction is stuck, what to do?" - an explainer [DRAFT]

In the last days we have been experiencing a sharp rise in price, which is historically correlated with many people transacting over the Bitcoin network. Many people transacting over the Bitcoin network implies that the blockspace is in popular demand, meaning that when you send a transaction, it has to compete with other transactions for the inclusion in one of the blocks in the future. Miners are motivated by profits and transactions that pay more than other transactions are preferred when mining a new block. Although the network is working as intended (blockspace is a scarce good, subject to supply/demand dynamics, regulated purely by fees), people who are unfamiliar with it might feel worried that their transaction is “stuck” or otherwise somehow lost or “in limbo”. This post attempts to explain how the mempool works, how to optimize fees and that one does not need to worry about their funds.

TL;DR: Your funds are safe. Just be patient* and it'll be confirmed at some point. A transaction either will be confirmed or it never leaves your wallet, so there is nothing to worry about in regards to the safety of your coins.

You can see how the mempool "ebbs and flows", and lower fee tx's get confirmed in the "ebb" times (weekends, nights): https://jochen-hoenicke.de/queue/#0,30d
* if you are in hurry there are things like RBF (Replace By Fee) and CPFC (Child Pays For Parent), which you can use to boost your transaction fees; you will need an advanced wallet like Bitcoin Core or Electrum for that though. Keep also in mind that this is not possible with any transaction (RBF requires opt in before sending, f.ex). If nothing else works and your transaction really needs a soon confirmation, you can try and contact a mining pool to ask them if they would include your transaction. Some mining pools even offer a web-interface for this: 1, 2.
Here’s how Andreas Antonopoulos describes it:
In bitcoin there is no "in transit". Transactions are atomic meaning they either happen all at once or don't happen at all. There is no situation where they "leave" one wallet and are not simultaneously and instantaneously in the destination address. Either the transaction happened or it didn't. The only time you can't see the funds is if your wallet is hiding them because it is tracking a pending transaction and doesn't want you to try and spend funds that are already being spent in another transaction. It doesn't mean the money is in limbo, it's just your wallet waiting to see the outcome. If that is the case, you just wait. Eventually the transaction will either happen or will be deleted by the network.
tl;dr: your funds are safe

How is the speed of confirmations determined in bitcoin?

Open this site: https://jochen-hoenicke.de/queue/#0,2w
Here you see how many transactions are currently (and were historically) waiting to be confirmed, i.e how many transactions are currently competing with your transaction for blockspace (=confirmation).
You can see two important things: the differently coloured layers, each layer representing a different fee (higher layer = higher fees). You can point at a layer and see which fees (expressed in sat/byte) are represented in this layer. You can then deduct which layer your own transaction is currently at, and how far away from the top your position is (miners work through the mempool always from the top, simply because the tx's on top pay them more). You can estimate that each newly mined block removes roughly 1.xMB from the top (see the third graph which shows the mempool size in MB). On average, a new block is produced every ten minutes. But keep in mind that over time more transactions come into the mempool, so there can be periods where transactions are coming faster than transactions being “processed” by miners.
The second important observation is that the mempool "ebbs and flows", so even the lower paid transactions are periodically being confirmed at some point.
In short: what determines the speed of a confirmation is A) how high you set the fees (in sat/byte), B) how many other transactions with same or higher fees are currently competing with yours and C) how many transactions with higher paid fees will be broadcast after yours.
A) you can influence directly, B) you can observe in real time, but C) is difficult to predict. So it's always a little tricky to tell when the first confirmation happens if you set your fees low. But it's quite certain that at some point even the cheap transactions will come through.

So what happens if my transaction stays unconfirmed for days or even weeks?

Transactions are being broadcast by the full nodes on the network. Each node can adjust their settings for how long they keep unconfirmed transactions in their mempool. That’s why there is not a fixed amount of time after which a transaction is dropped from the mempool, but most nodes drop unconfirmed tx’s after two weeks [IS THIS CORRECT?]. This means that in the absolute worst case the unconfirmed transaction will simply disappear from the network, as if it never happened. Keep in mind that in those two weeks the coins never actually leave your wallet. It’s just that your wallet doesn’t show them as “available”, but you still have options like RBF and CPFP to get your transaction confirmed with higher fees, or to “cancel” your transaction by spending the same coins onto another address with a higher fee.

Helpful tools to estimate fees for future transactions:

Here are some resources that can help you estimate fees when sending a bitcoin transaction, so you don't end up overpaying (or underpaying) unnecessarily. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting. A selection of such wallets you can find here or here.
The order here is roughly from advanced to easy.
1) https://jochen-hoenicke.de/queue/#0,24h
Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past. Each coloured layer represents a different fee amount. F.ex the deep blue (lowest layer) are the 1sat/byte transactions, slightly brighter level above are the 2sat/byte transactions and so on.
The most interesting graph is the third one, which shows you the size of the current mempool in MB and the amount of transactions with different fee levels, which would compete with your transaction if you were to send it right now. This should help you estimating how high you need to set the fee (in sat/byte) in order to have it confirmed "soon". But this also should help you to see that even the 1sat/byte transactions get confirmed very regularly, especially on weekends and in the night periods, and that the spikes in the mempool are always temporary. For that you can switch to higher timeframes in the upper right corner, f.ex here is a 30 days view: https://jochen-hoenicke.de/queue/#0,30d. You clearly can see that the mempool is cyclical and you can set a very low fee if you are not in hurry.
2) https://mempool.space
This is also an overview of the current mempool status, although less visual than the previous one. It shows you some important stats, like the mempool size, some basic stats of the recent blocks (tx fees, size etc). Most importantly, it makes a projection of how large you need to set your fees in sat/byte if you want your transaction to be included in the next block, or within the next two/three/four blocks. You can see this projection in the left upper corner (the blocks coloured in brown).
3) https://whatthefee.io
This is a simple estimation tool. It shows you the likelihood (in %) of a particular fee size (in sat/byte) to be confirmed within a particular timeframe (measured in hours). It is very simple to use, but the disadvantage is that it shows you estimates only for the next 24 hours. You probably will overpay by this method if your transaction is less time sensitive than that.
4) https://twitter.com/CoreFeeHelper
This is a very simple bot that tweets out fees projections every hour or so. It tells you how you need to set the fees in order to be confirmed within 1hou6hours/12hours/1day/3days/1week. Very simple to use.
Hopefully one of these tools will help you save fees for your next bitcoin transaction. Or at least help you understand that even with a very low fee setting your transaction will be confirmed sooner or later. Furthermore, I hope it makes you understand how important it is to use a wallet that allows you to set your own fees.

Electrum unable to sign transaction properly

I'm new to using bitcoin and I'm trying to figure out a problem I've been having trying to broadcast a transaction with Electrum. Initially I was trying to send bitcoin using Electrum's built in "send" function, but kept receiving the error "scriptpubkey." After browsing other forums and seeing issues similar to what I was having, it seemed like people were saying that it was an issue with the server I was connected to. In some cases, people had to try 15-20 different servers before finally being able to send the transaction through.
I thought this was the probable cause of my situation as well so tried about 20 different servers but to no avail. Then I read about "pushing the raw hex transaction" (not sure if I am using the right lingo here) and decided to try that. I was able to make an offline transaction with Electrum and signed it, then obtained the hex code from the .txn file that was created.
I then tried to broadcast the hex code on blockchain.com/btc/pushtx, but I am still receiving the error " Code: -26, Error: scriptpubkey."
So after doing some more research it seems that my problem now is not that there was an issue with servers in Eluctrum, but rather my transactions are not being properly signed. So now I have a signed offline transaction that seems to be improperly signed by Electrum, and I am clueless as to how to correct this.
Is there a way to "unsign" the transaction and sign it again properly? How would I even go about doing that? I fear that I now have money locked up in this faulty transaction that I may not be able to recover. I have all my passwords and everything so I am confused why Electrum would not have signed it properly. I am very new to all this so I'm sure I could be missing something essential. Any advice on how to broadcast and complete my transaction would be much appreciated.
I am running the latest version of Electrum on a Windows 10 computer.

Edit: Latest version of Electrum being 4.0.2
Also, I suppose it is probably helpful to see the decoded transaction here:

Generating a Transaction Hash

I am wanting to be able to take paper wallets and transfer the Litecoin/Bitcoin/Dogecoin off of them into another wallet. I really don't want to download an app to my phone, scan QR codes, import that, transfer that, etc. I would love to be able to enter the private key into a offline website (like the websites that generates paper wallets) and API call or manually enter that into (https://live.blockcypher.com/ltc/pushtx/) and it will "sweep" the wallets.
But I cannot find any easy method of doing this that works for Litecoin, etc.. I am wanting to use the same method for newer people into cyrpto so I can give them paper wallets and not have to explain to them how to download four different wallets just to get their money.
I am looking for something like coinb.in, but for Litecoin.. chain.so claims to, but I dont see a place that does this for Litecoin, only Bitcoin.
Is there anything like this out there? I cant seem to find anything!

Are there still any working mining pool BTC accelerator services? Let's list them to help out those who get stuck as fees moon.

A quick search reveals a couple, but I don't know how operational they still are, so maybe people who've used them recently can confirm.
ViaBTC: https://pool.viabtc.com/tools/txaccelerator
BTC.com: https://pushtx.btc.com
These are also the only ones still listed on the BTC wiki.
I'm not going to bother listing any of the dodgy third party ones I found, but if someone has good experience with another mining pool accelerator please mention it.

Attention, benevolent BCH miners: A BCH segwit-recovery service is sorely needed!

These BCH are now recoverable; please read the update at the end of the post!



In the short while since segwit activated on the BTC network and segwit addresses even-more-recently became the default for receiving BTC in the Trezor wallet - and perhaps other wallets too (soon?) - people have started accidentally sending their BCH to BTC-segwit addresses.
Due to the fact(s) that...
a) the BCH network supports P2SH (i.e. addresses starting with 3), but not segwit
... and ...
b) the sending wallets thus have no way of knowing that P2SH-wrapped segwit addresses really are "hiding" a segwit redeemscript
... people are losing access to their BCH, there's currently no way to prevent this, and it will continue happening.


(These are just the ones that I've noticed, but I'm sure there are many more that go straight to the various wallet service providers' support teams instead of via Reddit.)
To add insult to injury, the unlucky BCH owners are routinely told that there's no way to recover the coins (including by myself at the start) due to BCH not supporting segwit. And while that's currently true, it is ultimately only a half-truth.
After all, segwit opponents have often said that the satoshis in segwit addresses would be "anyone-can-spend" if the miners didn't enforce the segwit rules (i.e. ensuring that there's a proper witness/signature in the "segregated" part of the txs).
And on the BCH network the segwit rules aren't being enforced!

A Partial Solution

So I did some digging (e.g. in the segwit documentation and P2SH specification, BIP16) and came to the conclusion, which I'm sure that many have before me, that in order to spend money sent to a P2SH-wrapped segwit address, you only need to know the public key of the address (or more precisely: the RIPEMD160 hash of the SHA256 hash of a the public key).
Yes, a hash derived from the public key, not the private key.
Luckily, the 3-addresses don't by themselves reveal this public key hash, or anyone could've made "signed" txs from these "BCH-segwit" addresses - and someone probably already would have.

More Problems

So, given that it's relatively easy (for a technically inclined person, anyway) to get the public key corresponding to an address from their BIP39 mnemonic (aka wallet recovery seed), why aren't people re-claiming their BCH from these addresses?
Well, the "signature" that's needed isn't really a digital signature in the normal sense. Regular cryptocurrency transactions include a digital signature that doesn't reveal the private key that was used to make the signature in question. What's needed to "sign" for BCH-segwit addresses, however, is just literally including the public key hash that was mentioned above instead of a proper digital signature.
This means that anyone who sees such a transaction can just extract the public key hash from it - and then go on to create a conflicting transaction, using the same public key hash, that sends the same money elsewhere (to themselves, I would presume).
Technically, the second transaction would be a double-spend of the original and, as with all double-spends, it's the miners that would be the final arbiters of which transaction gets recorded in the block chain.
Additionally, a malicious miner could just create their own version of the transaction, either overtly redirecting the money to themselves, or covertly by changing the transaction to have no monetary outputs (i.e. all the money would go to the miner as "fee").
But the problems don't stop there. These segwit-spending transactions would be non-standard and as such wouldn't be relayed to the miners in the first place, nor would it be mined by miners even if it reached them (provided that the nodes and miners run with the default policy of ignoring non-standard txs, that is).

Suggested Solution

What we need is one or more trustworthy (yes, trust would unfortunately be required) miners to step up and make a BCH Segwit-Recovery Service for this particular purpose, in a somewhat similar way that they provided acceleration services for the BTC network (example1 and example2).
So... Does anyone know if a) miners are already working on this or b) know how to get in touch with them about this?
Or are there any benevolent miners here, that would like to:
/btc users, feel free to notify any miner contacts you may have - let's make this happen!

Update 1 (2017-09-11)

I made a proof-of-concept frontend to "show" what I'm envisioning such a service would look like for the end users (obviously it's ugly and needs to include javascript for key/hash/address validation, etc., but it should get the intention across), here:

Update 2 (2017-11-21)

It looks like some greyhat/vigilante, working with an unknown miner, was able to unilaterally claim some of the BCH that were "stuck" in BTC-segwit addresses (namely, the ones for which the public keys were revealed by the owners spending BTC from the same addresses), as explained in this post and comments: https://np.reddit.com/Bitcoin/comments/7eixcu/recovering_bch_sent_to_segwit_addresses/
For those that are affected by this, it means you no longer control your BCH (they were "stolen" by the greyhat), but he seems to be offering to give them back if you agree to letting him keep 30 % for his service (or "service", however you look at it). Either way, and given the alternative (100 % loss), you should certainly check if you're affected and decide how you want to proceed. As if that wasn't enough to deal with, there seems to be a ~2 week deadline, until "December 5th, 2017 at 23:59:59 UTC", after which it seems he's decided he's entitled to keep your money. :(

Update 3 (2017-11-28)

It looks like the greyhat has turned white! He's now offering to give back, for free, any and all BCH that were transferred to him (yes, 100 %!). Read his new update post and check if you were affected by this transfer.

Update 4 (2017-12-05)

Benevolent BCH miner finally found! The good people at btc.com have announced an automated BCH-segwit-recovery service, just as I outlined in my original post. Thanks a lot to Stellaluna19 for bringing it to my attention.
Here are links to btc.com's Twitter announcement as well as the recovery service itself:
(Note that SatoshiLabs/Trezor developer, and well-known whitehat, -johoe have suggested some improvements to secure the process outlined by btc.com. You can read his suggestions in the last paragraph of this post - or in this one.)

blockchain.info / spoofed transactions problem / Aug. 4, 2015

hello bitcoin community,
please excuse my english, i just want to clear things up. i'm a security researcher from central europe and i created yesterday's (Aug. 4, 2015) spoofed transactions on blockchain.info. many people have speculated whether satoshi has spent his coins or not, and that caused some panic. it wasn't my intention to harm the bitcoin community in any way and i'm sorry for what happened.
i simply created some transactions, signed them with a wrong private key and submitted them to https://blockchain.info/pushtx just to see what happens. in fact, the site accepted them! o.O
it's no hack, but rather a problem with blockchain.info's pushtx-api that could be used to trick sites which have implemented the 0-confirmation-api. best described by murbul - http://www.reddit.com/Bitcoin/comments/3frn1d/satoshis_coins_have_not_moved_blockchaininfo_is/ctriscn
source addresses i used: https://blockchain.info/address/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX https://blockchain.info/address/1HLoD9E4SDFFPDiYfNYnkBLQ85Y51J3Zb1 https://blockchain.info/address/1FvzCLoTPGANNjWoUo6jUGuAG3wg1w4YjR https://blockchain.info/address/15ubicBBWFnvoZLT7GiU2qxjRaKJPdkDMG https://blockchain.info/address/1JfbZRwdDHKZmuiZgYArJZhcuuzuw2HuMu

Transactions not going through??? Slow transactions?

Am I a victim of fraud? its been like 2 hours since i bought some bitcoin from some random website and since 2 hours is still says unconfirmed and 0 confirmations still, is it just me?
someone please help im afraid
edit : USED https://pushtx.btc.com PAID $20 AND I GOT 1 CONFIRMATION WITHIN 17-20 MINS, i was afraid so i used $20 , something new I learnt thanks everyone!
Ofcourse for smaller transations you cant afford services like these

Paid $83 in transaction fees on BTC to move my funds to altcoins. End up having to pay more to accelerate my transactions.

Since we learnt that Segwit2X will be cancelled, I had to quickly move my BTC into altcoins. Guess what? BTC is unusable, almost like a shitcoin now, had to pay $83+ just to move my BTC out into altcoins. But that's not the end of the story, to accelerate my transaction because apparently paying $83 is not enough to move my BTC transaction to the top, I had to use an accelerator https://pushtx.btc.com/
So I sent my Bitcoin Cash to pushtx.btc.com and guess what? I only paid 2 cents to move my Bitcoin Cash and the confirmation was so much faster. Yeah, BTC is now shitcoin. It's just speculators piling on top of each other selling it to the next bigger fool. Segwit is shitwit and BTC is shitcoin, I'm calling it now before the fools realize the truth.
Should I be angry having to pay $83 fees unnecessarily when I'm paying few cents on Bitcoin Cash for receiving the same service? Well, you decide.

So i had a bitcoin wallet from 2014 with a small amount of btc in it, that grew to enough to trade with so i thought id move it to the some exchanges, i made two transfers - both showed up in cryptopia as soon as i made the transfer, but after a week of waiting i and no confirmations i knew something was wrong
i was using an outdated version of multibit which had a very low fee set.
So i transfered the keys into a new wallet and made a another transfer with the largest fee option in hopes of clearing it through. and it kind of worked, one of the payments got confirmed at the same time, but the other one didnt. it is from 4/01/2018 and has 0/2 confirmations
i thought it would get rejected by the network after a month and returned but it still isnt available in my wallet.
i tried accelerating with https://pushtx.btc.com/
but i get the error message This is a double-spent tx, unavailable for acceleration
is there any known solutions for this, its been stuck for over a month now

The World Wide Web runs on webservers in datacenters. The World Wide Blockchain should also run on "blockservers" in datacenters. The "sweet spot" of Bitcoin scaling, reliability, security & convenience is *nodes in the cloud* + *private keys offline*. The is the future of Bitcoin. Let's embrace it.

Four-Line Summary
(1) Bitcoin nodes (and everyone's public addresses) should be online - in datacenters.
(2) Bitcoin wallets (and your private keys) should be offline - in your pocket.
(3) This architecture provides the optimal combination or "sweet spot" for short-term and long-term Bitcoin scaling, reliability, security & convenience.
(4) The best communications strategy is for us to embrace the approach of "nodes-in-datacenters" a/k/a "blockservers-in-the-cloud" - instead of apologizing for it.
Longer Summary
(1) Bitcoin nodes should be online - on "online public blockservers", ideally running on big, powerful webservers with high connectivity & high-end specs, in datacenters.
(2) Bitcoin private keys should be offline - in "offline private wallets", ideally running on tiny, cheap computers with no connectivity & low-end specs, in your pocket.
(3) We should embrace "nodes-in-datacenters" (ie, "blockservers-in-the-cloud") and "keys-in-your-pocket" as the future of Bitcoin, providing the optimal combination (or "sweet spot") of scaling, reliability, security & convenience.
Bitcoin has been a success for 7 years and is continuing to grow and needs a simple and safe way to scale.
So, now it is time for people to embrace nodes-in-datacenters a/k/a blockservers-in-the-cloud (plus private keys offline - to enable 100% security with "offline signing of transactions") as Bitcoin's future.
(1) ...because everything on the web actually works this way already - providing the optimal combination of scaling, reliability, security & convenience.
  • You already keep your passwords for websites and webmail on you - usually physically offline (in your head, written on a slip of paper, or maybe in an offline file, etc.)
  • When was the last time you ran a server out of your home to continually spider and index terabytes of data for the entire web?
  • Why should you need to hold 60 GB of data (and growing) when you just want to check the balance of a single Bitcoin address (eg, one of your addresses)?
  • Bitcoin is still very young, and if in order to fulfill its earlier promise about banking the unbanked, microtransactions, DACs (decentralized autonomous corporations), IoT (Internet of Things), smart contracts, etc., then we should hope and expect that the blockchain will someday take up terabytes, not "mere" gigabytes - just like Google's giant search engine index, which they update every few minutes.
  • Do you really think you should be performing this kind of heavy-duty indexing, querying and "serving" on a low-end machine behind a low-end connection in your home, when companies like Google can do it so much better?
  • As long as you physically control your own private keys, who cares if you rely on blockchain.info or blockexplorer.com (or someday: bitcoin.google.com or bitcoin.msn.com or bitcoin.yahoo.com) to lookup up public information about balances and transactions on Bitcoin addresses?
  • They're not going to be able to lie to you. The meaning of "permissionless" and "decentralized" is that anybody can set up a full-node / "blockserver" (plus "blockchain search engines"), and anybody can (and will) immediately report it to the whole world if a website like blockchain.info or blockexplorer.com (or someday: bitcoin.google.com or bitcoin.msn.com or bitcoin.yahoo.com) provides false information - which would seriously damage their business, so they'll never do it.
(2) ...because webservers and webmail don't lie to you, and "nodes-in-datacenters" (ie, "blockservers-in-the-cloud") aren't going to be able to lie to you either - since it would not be in their interest, and they would get caught if they did.
  • When was the last time google.com or or yahoo.com or msn.com (bing.com) lied to you when you performed a search or looked up some news?
  • When was the last time blockchain.info or blockexplorer.com lied to you when you checked the balance at a Bitcoin address?
  • Currently, with billions of websites and news sources ("webservers") running around the world in datacenters, there are "web search engines" (eg, google.com or news.google.com or msn.com or yahoo.com) where you can look up information and news on the World Wide Web. In order to survive, the business model of these "web search engines" is about getting lots of visitors, and providing you with reliable information. It's not in their best interests to lie - so they never do. These sites simply "spider" / "crawl" / "index" the entire massive web out there (every few minutes actually), and then conveniently filter / aggregate / present the results as a free service to you.
  • In the future, when there are 10,000 or 100,000 Bitcoin full-nodes ("blockservers") running around the world in datacenters, there will be "blockchain search engines" (eg, bitcoin.google.com or bitcoin.msn.com or bitcoin.yahoo.com - just like we already have blockchain.info and blockexplorer.com, etc.) where you will be able to lookup transactions and balances on the World Wide Blockchain. In order to survive, their business model will be about getting lots of visitors, and providing you with reliable information. It's not going to be in their best interests to lie - so they never will. These sites will simply "spider" / "crawl" / "index" the entire massive blockchain out there (every few minutes actually), and then conveniently filter / aggregate / present the results as a free service to you.
  • The business model for "blockchain search engines" might eventually showing ads or sponsored content along with the Bitcoin blockchain search functions which we are primarily interested in. This would be quite usable and simple and safe, and similar to how most people already use sites like google.com, yahoo.com, msn.com, etc.
(3) ...because "nodes-in-datacenters" (ie, "blockservers-in-the-cloud") provide simple scaling now.
  • Nodes-in-the-cloud are the only solution which can provide scaling now - using existing, tested software - by simply adjusting - or totally eliminating - the MAXBLOCKSIZE parameter.
  • They can use existing, tested, reliable software: thousands of 2MB+ nodes are already running.
  • About 1,000 Classic nodes have been spun up in AWS ECS datacenters (Amazon Web Services - Elastic Computer Cloud) in the past month. (Uninformed yes-men at r\bitcoin try to spin this as a "bad thing" - but we should embrace it as a "good thing", explicitly espousing the philosophy outlined in this post.)
  • "Nodes-in-datacenters" (ie, "blockservers-in-the-cloud") can be flexibly and easily configured to provide all the scaling needed in terms of:
    • Bandwidth (throughput)
    • Hard drive space (storage)
    • RAM (memory)
    • CPU (processing power)
  • The yes-men and sycophants and authoritarians and know-nothings on the censored subreddit r\bitcoin are forever fantasizing about some Rube Goldberg vaporware with a catchy name "Lightning Network" which doesn't even exist, and which (at best, if it ever does come into existence) would be doomed to be slow, centralized and expensive. LN is a non-thing.
  • Those same people on the censored r\bitcoin forum are desperately trying to interpret the thousands of Classic nodes as a negative thing - and their beloved non-existent Lightning Network as a positive thing. This is the kind of typical down-is-up, black-is-white thinking that always happens in a censorship bubble - because the so-called Lightning Network isn't even a thing - while Classic is a reality.
(4) ...because "nodes-in-datacenters" (ie, "blockservers-in-the-cloud") provide more reliability / availability.
  • 24/7/365 tech support,
  • automatic server reboots,
  • server uptime guarantees,
  • electrical power uptime guarantees.
(5) ...because "nodes-in-datacenters" (ie, "blockservers-in-the-cloud") provide better security.
(6) ...because "nodes-in-datacenters" (ie, "blockservers-in-the-cloud") provide more convenience.
(7) ...because separating "full-node" functionality from "wallet" functionality by implementing "hierarchical deterministic (HD)" wallets is cleaner, safer and more user-friendly.
Armory, BIP 0032 provide "hierarchical deterministic (HD)" wallets.
  • "Hierarchical deterministic" wallets are required in order to be able to keep private keys offline, and "offline-sign" transactions. This is because a wallet needs to be "deterministic" in order to be able to generate the same sequence of random private keys in the offline wallet and the online wallet.
  • "Hierarchical deterministic (HD)" wallets are also required in order to allow a user to perform a single, one-time, permanent backup of their wallet - which lasts forever (since a HD wallet already deterministically "knows" the exact sequence of all the private keys which it will generate, now and in the future - unlike the antiquated wallet in Core / Blockstream's insecure, non-user-friendly Bitcoin implementation, which pre-generates keys non-deterministically in batches of 100 - so old backups of Core / Blockstream wallets could actually be missing later-generated private keys, rendering those backups useless).
  • Bitcoin is now over 7 years old, but Core / Blockstream has mysteriously failed to provide this simple, essential feature of HD wallets - while several other Bitcoin implementations have already provided this.
  • This feature is extremely simple, because it is all done entirely offline - not networking, no game theory, no non-deterministic behavior, no concurrency. The "HD wallet" functionality just needs some very basic, standard crypto and random-number libraries to generate a "seed" which determines the entire sequence of all the private keys which the wallet can generate.
  • Newer Bitcoin implementations (unlike Core / Blockstream) have now "modularized" their code, also separating "full-node" functionality from "wallet" functionality at the source code level:
  • in Golang - "btcsuite" from Conformal, providing "btcd" (node) and "btcwallet" (wallet):
  • in Haskell + MySQL/SQLite - "Haskoin":
  • There is also a Bitcoin implementation which provides only a full-node:
  • in Ruby + Postgres - "Toshi" from CoinBase:
  • [Tinfoil] The fact that Core / Blockstream has failed to provide HD and failed to clean up and modularize its messy spaghetti code - and the fact that Armory is now out of business (and both companies received millions of dollars in venture capital, and the lead dev of Armory left because the investors were creating needless obstacles regarding intellectual property rights, licensing, etc.) - these facts are suspicious because suggest that these corporations may be trying to discourage dev-friendliness, user-friendliness, security, convenience, and on-chain scaling.
(8) ...because the only thing most users really want and need is total physical control over their private keys.
  • Most people do not want or need to run a Bitcoin full-node, because:
    • A Bitcon full-node consumes lots of disk space and bandwidth, and can be expensive and complicated to set up, run, maintain, and secure.
    • A Bitcoin full-node requires an extremely high level of hardware and software security - which most computer users have never even attempted.
  • As Armory or Electrum users know, the simplest and safest way to provide 100% guaranteed security is by using "offline storage" or "cold storage" or "air gap".
  • In other words, ideally, you should never even let your private keys touch a device which has (or had) the hardware and/or software to go online - ie: no Wi-Fi, no 3G, and no Ethernet cable.
  • This offline machine is used only to generate private keys (where a Bitcoin private key is literally actually just any truly random number up to around 1078 ) - and also used to "offline-sign" transactions.
  • So it is simplest and safest if your private keys are on an offline machine which never can / did go online - and such as machine can be very cheap, because it really only needs to run some very basic random-number-generator and crypto libraries.
  • It would be simplest and safest for people to own a tiny cheap 100% secure offline computer to use only for:
    • generating / storing Bitcoin private keys
    • signing Bitcoin transactions
    • possibly also for generating / storing other kinds of private keys (other cryptocurrencies, GPG keys, etc.)
Four-Line Summary / Conclusion:
(1) Bitcoin nodes (and everyone's public addresses) should be online - in datacenters.
(2) Bitcoin wallets (and your private keys) should be offline - in your pocket.
(3) This architecture provides the optimal combination or "sweet spot" for short-term and long-term Bitcoin scaling, reliability, security & convenience.
(4) The best communications strategy is for us to embrace the approach of "nodes-in-datacenters" a/k/a "blockservers-in-the-cloud" - instead of apologizing for it.

Transaction stuck in mempool with Bitcoin ABC client

I am using Bitcoin ABC and I am trying to broadcast a transaction, but it hasn't been included in any blocks in the past day. Within the client it reports as Unconfirmed/mempool.
Is there a way to re-broadcast it, same as blockchain.info/pushtx ? Can I do that from the client? Why didn't it go out in the first place?

Recently, Stas Trock wrote about how real-world stateful smart contracts can be implemented, deployed and transacted against on the Bitcoin SV ledger. Stas worked closely with sCrypt founder Xiaohui Liu, leveraging the platform to develop the contract.In a Medium post about stateful smart contracts, Xiaohui credited nChain for the concept of OP_PUSH_TX. When more people use the Bitcoin the block size reached its limit of 1MB and Bitcoin network loaded severely. This leads to delay in transactions. In order to speed up the process of BTC Transaction confirmation the users of BTC left with no other choice else to use the BTC Transaction Accelerator. They need to pay huge miner fees but we provide the Free BTC Transaction Accelerator for fast ... Pushtx is a bitcoin transaction accelerator that allows you to get faster confirmations on your unconfirmed transactions. Due to the bulk transactions and frequent congestion in the bitcoin network… Bitcoin Transaction Accelerator, speed up bitcoin transaction! Gotta Go Fast BITCOIN!
