Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
     

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

https://www.youtube.com/watch?v=Snr5e8bzftI
This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

PSA: Clearing up some misconceptions about full nodes

It's time to clear up some misconceptions floating around about full nodes.
Myth: There are only about 5500 full nodes worldwide
This number comes from this site and it measured by trying to probe every nodes on their open ports.
Problem is, not all nodes actually have open ports that can be probed. Either because they are behind firewalls or because their users have configured them to not listen for connections.
Nobody knows how many full nodes there are, since many people don't know how to forward ports behind a firewall, and bandwidth can be costly, its quite likely that the number of nodes with closed ports is at least another several thousand.
Nodes with open ports are able to upload blocks to new full nodes. In all other ways they are the same as nodes with closed ports. But because open-port-nodes can be measured and closed-port-nodes cannot, some members of the bitcoin community have been mistaken into believing that open-port-nodes are that matters.
Myth: This number of nodes matters and/or is too low.
Nodes with open ports are useful to the bitcoin network because they help bootstrap new nodes by uploading historical blocks, they are a measure of bandwidth capacity. Right now there is no shortage of bandwidth capacity, and if there was it could be easily added by renting cloud servers.
The problem is not bandwidth or connections, but trust, security and privacy. Let me explain.
Full nodes are able to check that all of bitcoin's rules are being followed. Rules like following the inflation schedule, no double spending, no spending of coins that don't belong to the holder of the private key and all the other rules required to make bitcoin work (e.g. difficulty)
Full nodes are what make bitcoin trustless. No longer do you have to trust a financial institution like a bank or paypal, you can simply run software on your own computer. To put simply, the only node that matters is the one you use
Myth: There is no incentive to run nodes, the network relies on altruism
It is very much in the individual bitcoin's users rational self interest to run a full node and use it as their wallet.
Using a full node as your wallet is the only way to know for sure that none of bitcoin's rules have been broken. Rules like no coins were spent not belonging to the owner, that no coins were spent twice, that no inflation happens outside of the schedule and that all the rules needed to make the system work are followed (e.g. difficulty.) All other kinds of wallet involve trusting a third party server.
All these checks done by full nodes also increase the security. There are many attacks possible against lightweight wallets that do not affect full node wallets.
This is not just mindless paranoia, there have been real world examples where full node users were unaffected by turmoil in the rest of the bitcoin ecosystem. The 4th July 2015 accidental chain fork effected many kinds of wallets. Here is the wiki page on this event https://en.bitcoin.it/wiki/July_2015_chain_forks#Wallet_Advice
Notice how updated node software was completely unaffected by the fork. All other wallets required either extra confirmations or checking that the third-party institution was running the correct version.
Full nodes wallets are also currently the most private way to use Bitcoin, with nobody else learning which bitcoin addresses belong to you. All other lightweight wallets leak information about which addresses are yours because they must query third-party servers. The Electrum servers will know which addresses belong to you and can link them together. Despite bloom filtering, lightweight wallets based on BitcoinJ do not provide much privacy against nodes who connected directly to the wallet or wiretappers.
For many use cases, such privacy may not be required. But an important reason to run a full node and use it as a wallet is to get the full privacy benefits.
Myth: I can just set up a node on a cloud server instance and leave it
To get the benefits of running a full node, you must use it as your wallet, preferably on hardware you control.
Most people who do this do not use a full node as their wallet. Unfortunately because Bitcoin has a similar name to Bittorrent, some people believe that upload capacity is the most important thing for a healthy network. As I've explained above: bandwidth and connections are not a problem today, trust, security and privacy are.
Myth: Running a full node is not recommended, most people should use a lightweight client
This was common advice in 2012, but since then the full node software has vastly improved in terms of user experience.
If you cannot spare the disk space to store the blockchain, you can enable pruning. In Bitcoin Core 0.12, pruning being enabled will leave the wallet enabled. Altogether this should require less than 900MB of hard disk space.
If you cannot spare the bandwidth to upload blocks to other nodes, there are number of options to reduce or eliminate the bandwidth requirement. These include limiting connections, bandwidth targetting and disabling listening. Bitcoin Core 0.12 has the new option -blocksonly, where the node will not download unconfirmed transaction and only download new blocks. This more than halves the bandwidth usage at the expense of not seeing unconfirmed transactions.
Synchronizing the blockchain for a new node has improved since 2012 too. Features like headers-first and libsecp256k1 have greatly improved the initial synchronization time.
It can be further improved by setting -dbcache=3000 which keeps more of the UTXO set in memory. It reduces the amount of time reading from disk and therefore speeds up synchronization. Tests showed that the entire blockchain can now be synchronized in less than 3 and a half hours (Note that you'll need Bitcoin Core 0.12 or later to get all these efficiency improvements) Another example with 2h 25m
How to run a full node as your wallet.
I think every moderate user of bitcoin would benefit by running a full node and using it as their wallet. There are several ways to do this.
So what are you waiting for? The benefits are many, the downsides are not that bad. The more people do this, the more robust and healthy the bitcoin ecosystem is.

Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 518 Full Nodes running.

Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 518 Full Nodes running.
Official node scanner list: https://scanner.vertcoin.org/nodes
Since every full VTC node can only serve so many clients, it's important to do your part for the Vertcoin network and run your own full node.
Q: WHAT IS A FULL NODE? A: Full nodes maintain a copy of the blockchain/ledger, distribute it to those downloading it, confirm transactions, and further spread out all of the previous functions to make the network more resilient. https://bitcoin.org/en/full-node
Q: Do I need to be a miner? A: No, you don't need to be a miner. Miners create new blocks. Full nodes simply share existing blocks (the entire VTC blockchain) with the rest of VTC wallet users.
Q: How do I run a Full VTC node on Intel NUC? A: Intel NUC Vertcoin full node installation done using Windows guide: https://github.com/vertcoin-project/VertDocs/blob/mastedocs/FullNodes/intel-nuc.md
Q: How do I run a Full VTC node? A: It's actually quite easy to do. If you run Vertcoin-QT (Vertcoin Core Wallet) on your PC/MAC desktop, keep it active in the systray. Then, make sure that you map the public port 5889 of your router to the port 5889 on the machine running Vertcoin-QT or vertcoind. For people running a public p2pool node this should be a no-brainer: you already have a synchronized vertcoind. So if you haven't opened port 5889 do it now - it's all you have to do. Your node is then public and can serve blocks and relay transactions.This makes our network much stronger and will help it to perform better. Any old or low power computer is good enough to run a full VTC node. If you have a Raspberry Pi or any old PC lying around, install vertcoind and run it in the background.
Q: How do I know if my Full Node is working correctly? A: To be a full node, you have to check to make sure you are accepting incoming connections. To do that, go under Help -> Debug Window. In the first tab, "Information", there is a Network "Number of Connections" which will show both incoming and outgoing connections. If the "In" is 0, then you are not a full node. If the "In" is greater than 0, you are acting as a full node and supporting VTC blockchain! Thank you!

For people running a public p2pool node this should be a no-brainer: you already have a synchronized vertcoind. So if you haven't opened port 5889 do it now - it's all you have to do. Your node is then public and can serve blocks and relay transactions.This makes our network much stronger and will help it to perform better. Any old or low power computer is good enough to run a full VTC node. If you have a Raspberry Pi or any old PC lying around, install vertcoind and run it in the background.
Q: How do I know if my Full Node is working correctly? A: To be a full node, you have to check to make sure you are accepting incoming connections. To do that, go under Help -> Debug Window. In the first tab, "Information", there is a Network "Number of Connections" which will show both incoming and outgoing connections. If the "In" is 0, then you are not a full node. If the "In" is greater than 0, you are acting as a full node and supporting VTC blockchain! Thank you!

I just verified that BU and SV block chain data structures are compatible! No need to download the block chain from scratch if migrating to SV.

Since BU hasn't still officially announced nor released a Satoshi Vision compatible change set and time is running out, I started migrating cryptograffiti.info from Bitcoin Unlimited to Satoshi Vision (to guarantee that after 15th of Nov my service is still attached to what I perceive as the original Bitcoin).
I copy-pasted the blocks and chainstate directories from BU datadir to SV datadir and simply launched my nonmining node. After a couple of minutes of network discovery the node was properly synchronized with the network and downloaded new blocks as they were found. The RPCs are working as expected.
While SV lacks the qt binaries (GUI), it is still usable as a backend software for block chain services such as cryptograffiti.info . If you want to be on a correct chain after the 15th and can't wait for BU or ABC to implement SV- compatible changes then rest assured, you don't have to download the whole block chain from scratch.

WolfCoin Wallet

The Wolfcoin blockchain and network are both designed and engineered to ensure store of value, transactional speed and security, and fungibility. The main goal of the Wolfcoin blockchain is to facilitate fast and secure transactions with a governance that helps sustain the network for the benefit of all users. The Wolfcoin blockchain is a two-tier network comprised of a Proof of Work (PoW) consensus mechanism powered by miners and a Proof of Service (PoSe) system powered by masternodes. Miners receive rewards for ensuring the security of the blockchain and masternodes are rewarded for facilitating the features of the network including Private Send and Instant Send. Wolfcoin uses the X11 hashing algorithm and is based on the Bitcoin Core codebase version 0.12.
  1. Download the Wolfcoin Wallet. Place the Wolfcoin Wallet zip file on your desktop, and extract all of the files on your desktop. Open the new Wolfcoin Wallet Folder. And run the the Wolfcoin QT File. The wallet will now load and start downloading the Blockchain and syncronizing with the Wolfcoin Network.
  2. Once the Wolfcoin Wallet is fully synchronized, you're Wolfcoin Wallet is now ready, and fully installed. Please click on Settings and then Encrypt Wallet. Create your password or passphrase, and save it somewhere safe as if you lose it, you'll lose all of your Wolfcoins as well. The wallet will now close down, and please reopen it.
  3. Once you've restarted the Wolfcoin Wallet, and it's fully synchronized again, now click on File and click on Backup Wallet. Save the file as 'wallet.dat', and save it in a folder named Wolfcoin Wallet. Please save this folder and file on a USB, or another HD for safe keeping as this file is your wallet and all of your Wolfcoins. Your Wolfcoin Wallet is now ready, backed up, encrypted, and ready to be used.

Let me love the Bitcoin, please.

After reading tiny snippets about Bitcoin all the time I decided to take a closer look at it ... and I was floored.
Please don't get me wrong, I really really really want to love the concept, but it seems to be more or less unusable. There are some huge upsides to it: Built on mistrust, fixed amount of money, decentralized system, anonymity and so on. But my reality looked something like this:
Now as you might say, I should have read up on the details (blockchain!) before - but getting started seems to be a big hurdle for the non-geeks out there. Nothing like "get started in seconds!". Even I had some trouble grasping the concept, and I'm sitting in front of a computer for about two decades now.
But wait, there's more! Since my connection is still under heavy load from the client, I could read up on all the things I have missed, and I found some inherent flaws:
For me, Bitcoins could be an awesome form of worldwide, internet-based form of micropayments. The biggest market would be developing countries. But there are technical and legal barriers which push it into a corner for geeks who see conspiracies everywhere and want to crash the system ... which is exactly not what it should be. I read about Ripple, it seems to be a better alternative just because of the possibility for easy money exchanges - and it includes Bitcoin, too.
So, is there something I just don't get yet? I get the impression Bitcoin is a great idea, but just the prototype for something better.

How to run a Bitcoin Cash full node properly?

I would like to run a Bitcoin Cash full node to support the network.
I've done the following steps:
My client seemed to be syncing without any issue until the first Bitcoin Cash block (478558). After this block the the synchronization stopped. I haven't modified the default "Bitcoin-Qt.conf" file. My client is connected currently to 8 other nodes (6xBitcoin ABC, 1xBUCash and 1xBitcoinUnlimited). The debug log is huge it is about 100MB. At the end of the log file there are few messages like this:
AcceptBlockHeader: block is marked invalid
or [Net] Id: 1434 0 => 100 Ban threshold exceeded
Any idea why is my client stuck at block 478558?

Basic Bitcoin security guide

Hello,
This post is to give you a quick introduction into Bitcoin security. While nobody can guarantee you 100% security, I hope to mitigate some problems you can run into. This is the “20% of effort to get you to 80% safe”.
First of all, you have to determine how much money you want to hold in Bitcoin and how much effort are you willing to put in. If you are happy just holding a few dollars worth and don’t care if you lose them, that’s one approach to take. For everyone else, lets get started.
Password strength
A lot of the times how secure your money is will be determined by the strength of your password. Since in the worst case scenario we are talking about someone trying to brute force your wallet, casual online passwords are too weak. Under 10 characters is too weak. Common words and phrases are too weak. Adding one number to a password at the end is too weak.
Moreover, you can consider your password much weaker if you:
If you want a really strong password:
Wallet security
Now we are getting to the meat of things.
There are a number of wallets available to store your hard earned bitcoins. If you have a decent amount of coins to store, you should look into software wallets - BitcoinQT, MultiBit, Armory or Electrum. They are among the best place to store your money safely (provided your computer is secure as well). Chose one you think best suits you, install it and encrypt your wallet file with your strong password. You should take your wallet file and back it up (location of the file is different for different clients, so you have to do some research as to where to find that file). Back it up on a CD, safe USB drive or the like. Keep them safe. If you lose that file, you will lose your money.
A quick word on deterministic wallets. Electrum and Armory allow you to create wallets from a seed. If you use the same seed later, you can recreate your wallet on other machines. With deterministic wallets, you only need to keep that seed secure to have access to your money.
In comparison, in BitcoinQT's traditional wallet, every address you use is random, meaning that after you send 50-100 outgoing transactions your backups can be obsolete. Always keep an up-to-date backup of such wallet file if possible.
Okay, sometimes you need to have your Bitcoins with you when you leave your computer. In this case, you should look into either online or mobile wallets. A staple for both of those is Blockchain.info, but there are others to chose from.
A good rule of thumb with these is to not store more money in them than you can afford to lose. They are best used as a convenient way of accessing some money, not storing your savings. Online wallets are especially vulnerable to their servers getting hacked and people’s money getting stolen.
What to keep in mind while using online wallets:
  • Use a secure password (the more money you have in them the stronger the password should be)
  • Always keep a backup of your wallet in case you need to recover your money
  • Whenever possible, enable two factor authentication
  • Don’t use your online wallets from unsafe computers
Cold storage
Sometimes you want to store your bitcoins for a long time in a safe place. This is called “cold storage”. There are a few ways one can do this.
First of all, paper wallets. They are nice for giving people small bitcoin gifts, but also for long-term storage if properly used. What you want to do is generate and print them offline. You can save the linked page for example and run that offline. If you are really paranoid, you can put it on read-only media and access that from a different computer. For really long term storage, use archival-grade paper.
Another approach to take is using a separate computer for storing your money that is offline 99+% of the time. You could set one up easily by buying an old laptop, reformatting it, installing Linux and a Bitcoin client. Generate an address on that machine and send money to it from your main wallet. Depending on how paranoid you are you can connect that computer to the Internet afterwards to synchronize data with the Bitcoin Network and then turn it off and put it away somewhere safe until it’s needed.
Brain wallets
Don’t. They are not for you. Unless you are a security-conscientious programmer, those are not for you.
Diversifying
Keeping all of your eggs in one basket is never a good thing. You should look into diversifying some of your Bitcoin assets in case your other storage methods fail. Some ways you can diversify:
  • Buy a physical Bitcoin. As long as you trust the coin creator such coins can be an effective cold storage
  • Invest - I wouldn’t recommend this for more than some trivial amount unless you know what you are doing, but investing in some Bitcoin stocks could be a way to get more money out of your bitcoins
How not to diversify:
  • Avoid keeping your bitcoins at exchanges or other online sites that are not your online wallets. Such sites can be closed down or disappear along with your money.
  • Alt-coins - there are few cryptocurrencies that are worthwhile, but most of them are just Bitcoin clones. If a currency brings nothing new, it’s worthless in comparison to Bitcoin. Namecoin is a distributed domain name server (although recently it had a fatal flaw uncovered, so be warned), Ripple is a distributed currency exchange and payment system. Litecoin will only be useful in case Bitcoin’s hashing algorithm gets compromised (very unlikely at this time). Beyond that there are few if any alt-coins that are a worthwhile way of diversifying.
Accepting payments and safety
We’ve covered safe ways to store money, now a quick note about bitcoin payments and their safety.
First of all, when you are sending a transaction, pay your fees. Transactions without fees can take forever to propagate, confirm and clear. This can cause you a lot of stress, so pay your fees.
Secondly, when accepting large Bitcoin payments (say you want to suddenly cash in a gold bar into bitcoins), wait for at the very least 1 confirmation on those transactions. 6 is best, but having even 1 confirmations is a lot better than having none. This is mainly a rule of thumb for the paranoid (I wouldn’t be doing this for most casual transaction), but maybe it will save you if you are dealing with some shady people.
Wrapping up...
That should cover the basics. If you want to read more about Bitcoin’s security in general, here is my master thesis on the subject. A lot of questions about Bitcoin and security have also been answered on Bitcoin StackExchange - be sure to check it out.
Comments and improvement suggestions welcome.
EDITS:
  • Removed link to insecure site
  • Removed random article section
  • Added information about deterministic wallets

Bitcoin Core 0.10.1 Released

Bitcoin Core version 0.10.1 is now available from:
https://bitcoin.org/bin/bitcoin-core-0.10.1/
This is a new minor version release, bringing bug fixes and translation updates. If you are using 0.10.0, it is recommended to upgrade to this version.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

Upgrading and downgrading

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

Downgrade warning

Because release 0.10.0 and later makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
If you want to be able to downgrade smoothly, make a backup of your entire data directory. Without this your node will need start syncing (or importing from bootstrap.dat) anew afterwards. It is possible that the data from a completely synchronised 0.10 node may be usable in older versions as-is, but this is not supported and may break as soon as the older version attempts to reindex.
This does not affect wallet forward or backward compatibility.

Notable changes

This is a minor release and hence there are no notable changes. For the notable changes in 0.10, refer to the release notes for the 0.10.0 release at https://github.com/bitcoin/bitcoin/blob/v0.10.0/doc/release-notes.md

0.10.1 Change log

Detailed release notes follow. This overview includes changes that affect external behavior, not code moves, refactors or string updates.

Block (database) and transaction handling:
P2P protocol and network code:

How to create a Litecoin wallet.

This will be a guide on how to create a Litecoin wallet.
I will try to make this as noob friendly as possible.
The wallet we will be using will be the Litecoin-qt wallet. This wallet is made by the Litecoin dev team and is pretty much the same thing as the Bitcoin-qt wallet except for Litecoins. This is a local wallet that will reside on your computer and not online.
Having a wallet on your computer is the best way to store your coins. You dont have to put trust in anyone else to keep your coins safe. Almost every online Bitcoin wallet has been hacked leading to user funds being stolen. NEVER, EVER, EVER trust anyone to hold your coins except yourself. That being said by storing your own coins you do have to take some precautions to keep them safe. I will instruct you on how to encrypt your wallet but there are still better ways to lock your wallet down. I will write another tutorial on this subject at at a later time.
So to start you need to download the Litecoin wallet. You get this from https://litecoin.org/ ONLY DOWNLOAD THE LITECOIN WALLET FROM THIS ADDRESS. If you download it from anywhere else it could be corrupted and you could have your coins stolen. https://litecoin.org/ is the website run by the Litecoin dev team.
On the main page you will see links to download Windows, MAC, and Linux versions of the wallet. Download whichever one corresponds to the OS you use. I will assume Windows for this guide but for using a Mac you should install it like you do any other application.
Once you download it open the file and follow the prompts clicking next etc.
Once you are finished open up the Litecoin client. It should have put an icon on your desktop.
Once you open it up you will see the Litecoin-qt client. It might take a few seconds to load.
At the bottom you should see a bar with "Synchronizing with network" next to it. This means that the client is downloading all of the blocks in the blockchain. It will take a while to download all of the blocks (about 2.5GB worth) the first time. After the first time when you open the client it will only download the blocks that have been created since last time you used the client. When it is finished you will see the bar disappear and there will be a green check mark in the bottom right hand corner.
While we are at the bottom right hand corner if you hover your mouse over the signal bar looking icon it will tell you how many connections you have to the Litecoin network. So if for some reason you are not downloading any blocks then check this to make sure you are connected to the network.
To encrypt your wallet
At the top click Settings > Encrypt Wallet. Follow the prompt entering your password and make it a good one. After you encrypt your wallet you will see a padlock at the bottom right next to where the green check and the signal bars are.
WARNING IF YOU LOSE OR FORGET YOUR PASSWORD YOUR COINS ARE GONE FOREVER!!!
Now to send coins you click the send button and you enter the address, amount, and if you want to label the trans you do can do that also. Then you click send. You will have to enter your password if your wallet is encrypted.
To receive coins click the receive button. You will already have one address there. You can give this address to anyone or enter it in any service and you will receive coins to this wallet. If you want to make a separate address you click new address and give it a label and it will create a new address for you.
If you click the transactions tab you will see all of the transactions you have made both sending and receiving. If you hover over the box to the left of the date/time of the transaction you will see how many confirms it has.
Backing up your wallet
The Litecoin-qt client while called a wallet by some isnt really a wallet. Its a client used to access your wallet. The actual wallet is a file called a wallet.dat. This file has the public and private keys that let you spend your coins. (More on this in another topic).
If you want to backup your wallet (YOU SHOULD) then you simply need to copy this wallet.dat file onto something else like a USB flash drive. I suggest making several copies and putting at least one off site from your computer like at a family members house or in a safety deposit box. Make sure when you do this that you COPY the file and NOT move it.

Bitcoin-Qt on Mac questions

I am very new to Bitcoin. I downloaded the recommended software for BTC for my Mac, Bitcoin Core (Bitcoin-Qt on the icon) and I am beginning to use it. It has said "Synchronizing with network," at the bottom of the window for the past four hours and is on some arbitrary number like 138637 out of 279000 of unblocking... whatever that means...
Anyways, I made a transfer from coinbase.com to the wallet on Bitcoin-Qt and it has a receipt saying it went through, but because my Bitcoin-Qt wallet is "out of sync," nothing is showing up.
I guess my question(s) is (are), has anyone used this software before and is experiencing what I am experiencing? Is this normal? How long does it take for it to completely synchronize? Will my BTC transfer completely to my wallet after this has occurred?
Thanks

Syncing bitconnect wallet with network. Bitconnect wallet (not sync) *fix*. Programming Bitcoin-qt using the RPC api (1 of 6) How to speed up Bitcoin Core sync Bitcoin Core Network Sync Successful Bitcoin Wallet Recovery

It's most likely you're using the client from bitcoin.org. Synchronizing with the network refers to the download and verification of the blocks in the block chain, which is the transaction history of Bitcoin.The block chain is the record of who spent what and when they spent it, and who owns what now. Just type sudo apt-add-repository ppa:bitcoin/bitcoin in your terminal, then install the bitcoin-qt package. KNOWN ISSUES.
