Mined some coins around 2012 on bitcoin-qt, how do I sync my wallet.dat?

As titled. I haven't kept up as life had consumed me, but the last couple months I had a new bitcoin-qt synced up.
My old app would not even sync properly, but still kept on my harddrive, already been backed up.
Any advice?

Is there a way I can insert a receiving address from one wallet into a second? I bought some Bitcoin, but didn't have my wallet (Bitcoin Core) synced. Five days later, even with blockchain.dat downloaded, its still syncing - I need those coins. Which lite wallet(s) allow this - is it even possible?

I would suggest to not hassle around with bitcoin clients on your computer and ".dat"-files. it's not worth it to wait to get synced and having the full blockchain on the computer. use an spv-wallet like above and just save the 24-words. thats it.
if you want to run a full node on your computer and contribute to the system, then get a core-client. to store any funds there (only play-money). (a virus could easely read your .dat-file!)
[link]1 is save and open-source. use offline !!!
EDIT: if your paranoid: check the hash on github ([link]2 ) (so you know that you don't donwload a comprimized file) and use it on a computer (eg. old labtop with browser) that will never be online again. (a potential virus can not communicate to the outside)

Help recovering from old wallet.dat for an old friend.


Hey all,
I've been in the Bitcoin space since early 2012.
I have a situation that I would love to get some assistance with, I will explain the situation momentarily. Please do not message me and ask me for the wallet.dat file it's not going to happen.
TL;DR
I have an old wallet.dat file from late 2012 or early 2013 from a coin I sold to a friend. Tried to recover the coins in 2018 and failed, later found out that someone had access to the computer and could have easily stole them. Would the current Bitcoin Core be able to read an old wallet.dat file, and is there any way to easily view the balance of a 2012 wallet.dat file without having to load the entire blockchain?
In the early days of Bitcoin as many of you OG's know, the only option to securely store your coins was to use the default Bitcoin wallet in a wallet.dat file. A friend of mine was really wanted to invest in Bitcoin but didn't know how, so I sold one to him because I didn't want him to get screwed. I installed Bitcoin QT on their home laptop, had him write down the password on a piece of paper and had him put a backup of the wallet.dat file onto a USB.
Fast forward to when the price went to $20k plus, he calls me up super excited and said he wanted to sell his coin because he could use the money and I encouraged it because from my prior experience I knew the momentum was unsustainable and I had sold a few coins of my own.
Anyway, I go over to his house and we huddle around his computer. He tells me that he upgraded the hard drive in his computer and gave me his old one and I went back to my house to get an external hard drive reader. I came back, booted up his old drive and remembered that we would have to let it sync up in order to get the coins out, and on his internet that wasn't going to happen anytime soon. He gave me the hard drive and I went home and left on Bitcoin QT overnight and in the morning I was shocked to see that there were no transactions on the wallet. Quick note, he had the wallet password in a file on his documents titled "Bitcoin Wallet Password.txt". smh.
I started to panic, and I realized how bad this looked on me. I called him and told him that there were no coins on there and asked if he had his USB stick and he told me he had lost it years ago. I frantically looked through all of my old wallet files to find any transaction that could link to his address, to show that his coins were still in there. After a while I realized I had sent the coins from the now defunct btc-e.com, and had no way to check up on the coins.
I did everything in my ability to try to recover lost data from the hard drive to no avail. I asked him if anyone else has had access to his computer, and then asked him how he replaced his hard drive because I know him well enough to know he wouldn't pull apart a laptop to replace the hard drive. He told me he took it to a shop to have it replaced a few months earlier. I suspect that I'm either trying to view the wallet incorrectly or whoever replaced his hard drive snooped on his hard drive, stole the coins and replaced the wallet.dat file and generated a new one. I have to admit, I was relieved a little bit to have an explanation to coins not being there but I could imagine he thinks I may have had something to do with it. I made a few more attempts over the years whenever I was reminded of the situation to no avail.
We kind of fell out after that and haven't spoken in a while. Recently, I saw a post on his Facebook that his wife is pregnant they are having a baby, and that's why I'm here. I would love nothing more than to be able to message him and let him know that I have 11 grand waiting for him, because I'm certain the money would mean the world to him during such a stressful time.
Any help or insights would be incredibly helpful and appreciated.

Found old (2012) wallet.dat file on old external drive - need help please!

Hi there - just wondering if there's an easy way to check an old wallet.dat file that I found from long ago. I know nothing about bitcoin, I don't use it for anything, but I think I may have mined it for a few days a long time ago and it would be nice to know if I have even 0.1 coins to my name.I have read numerous posts and articles telling me to "Download and sync the core" - my hard drive can't hold that much data - it's only a 256 SSD - how can I check my balance? I've read about "pruning" as well - would that work or do I need the whole blockchain on my hard drive to check?
It's all very confusing and I'd really appreciate a simple explanation. Thanks!

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

I found a lost bitcoin wallet from 2012

So I was going through an old laptop and found the wallet.dat file in %APPDATA%. If I remember correctly I had 0.7 bitcoins mined.
Could anyone with knowledge please help with a couple of questions?
  1. is the balance stored in the wallet itself or do you use it to download blockchain info or some such to work it out?
  2. What can I use to view my wallet? I've read that there are a few formats (Berkley, Level) depending on age. I'd love a simple C# lib or small open source exe..
  3. Is the wallet locked with a password?
A big thanks to anyone taking time to reply :)
Edit: have 0.76 bitcoin ($5k USD). Thanks to all who replied for help and thanks quarantine!
