My experience buying Bitcoin at GSM Solutions Bitcoins ...

Are there any bitcoin ATMs in Dublin?

I know there used to be GSM solutions but they're closed down and localbitcoins have stopped offering local trades so can't find anything else to buy bitcoin in Dublin

Edit: I found 3 shops in Dublin that have bitcoin ATMs:
PAIR on Wicklow St.
IT-fix on Parnell St.
IT-fix on Capel St.

Thanks for the suggestions too :)

Why I believe in the future of Bitcoin

I see a lot of confusion in this subreddit about what is meant by 2nd-layer solutions and how it can help our current problem with the saturated mempool and high tx fees, so I thought I would try to explain it using a piece of tech we all use: the internet.
Using the OSI-model, the internet is build of 7 layers.
The first layer is the Physical layer. This defines the physical connection between two pieces of hardware: the Ethernet connection between your computer and switch, the WiFi between your tablet and router, or the GSM connection between your phone and the carrier antenna. This is were the bits are sent back and forth.
Next comes the Data Link layer. This facilitates node-to-node data transfer. The Physical layer does not know if any of the bits were corrupted, so the Data Link layer provides error detection. This allows your computer to communicate with your router.
On top of that is the Network layer. This is where the magic of the internet happens. The Network layer allows nodes which are not immediately connected to communicate, by routing the data from node to node, until it reaches its destination. This is how your computer communicates with servers all around the world, as they are all connected in a big web of nodes small (switches) and big (ISPs).
After that comes the Transport layer. If you have ever heard of TCP or UDP, this is it. The Network layer is used to sent single packets of data through the web, but as they are quite small a single file is most often split into multiple packets. The Transport layer takes all these small packets, makes sure that all of them has arrived, and then places them in the correct order (as the individual packets can take different routes through the web, they most often don't arrive sequentially). Without the Transport layer, it would be impossible to send large files through the internet.
Last are the Session, Presentation and Application layers. These makes sure that the correct program gets the data which was requested. If you click on a link in your browser, a request is made to the server which contains the linked webpage, to send that site. When it arrives at your computer, you want the website to be given to your browser, and not your media player.
Right now Bitcoin is the first layer. Saying Bitcoin will never work as a global currency is saying that the physical layer will never work as the internet, since you would have to connect your computer to the remote server with an Ethernet cable. Of course this does not work, but this is why 2nd-layer solutions like the lightning network are being implemented.
This is also why increasing block size would only fix Bitcoins problems momentarily, as this is similar to upgrading your Ethernet cable from 100MB/s to 1GB/s. This increases the speed, but you still need all the other layers for the internet to work.

Hardware wallet for high security, yet cheap multisig

The Problem

For extra security by avoiding single points of failure such as hardware supply chain attacks or firmware bugs, multi-signature wallets with hardware wallets from different vendors are topic in the community.
Casa sells such a solution I think, with one $300 node that comes with the blockchain pre-downloaded and a wallet that supports such multi-signature setup (3 of 5 with key rotation if a hardware wallet is lost. Backups are pitched as a thing of the past or so).
So with the Casa setup as a random example, the user would spend $300 + 5 x $100 for hardware wallets. That is $800 for a multisig setup.
I think this should be much much cheaper to achieve broader use.

The Assumption

A hardware wallet consists of:
Different users want different features. Some would even consider more items optional as existing HW wallets prove. Future HW wallets may come with iris scanners, voice detection, etc. Who knows? All these features (?) would make the device even more expensive. $100 is about what current wallets cost.
Users will inevitably compromise depending on their holdings.
Users make completely random guesses as to how likely their current setup might result in a total loss.
If they decide their holdings should be protected by a hardware wallet, they should have no big down-side for going straight to multi-sig.

The Idea

Of the list above, the secure element costs $2 to $5 and comes in handy form factors such as ID1 (credit card) or micro SD.
A new hardware wallet could build on top of a standardized secure element that you can buy from all the hardware wallet providers. Hardware wallet providers should recognize that buying 5 wallets form the same vendor is not a good idea and supporting such an open standard would ease the users' minds that they can trust new providers in the market (such as d'cent for example, who also gave me the figure of how much a secure element would cost).
Instead of investing $500, I would invest $110 for a wallet with 5 microSDs. Both alternatives would involve multiple providers of course.

[Discussion] Idea: A "dashboard" dedicated to jailbreaking (Criticisms Requested)

This concept crossed my mind after Apple quit signing >11.2.5 and seeing comments like:
"when you get home to your computer to save blobs, but iTunes needs to update and before it completes you get hit with this news"
"I feel kinda lucky that I thought of saving newer blobs an hour ago..."
"I managed to get 11.2 blobs for my iPad 5 about 10 seconds ago. iPhone 8 was not as lucky"
Note: If you feel like this is a stupid idea, please let me know. I'm interested as to what y'all think! Would you see this helping you? Do you think it would be worth it? Anything you might do differently?
The Goal
An open source platform that centralizes much of the jailbreaking process through a dashboard capable of adapting it's content based on the state of an iOS device. Through user input and a system of automatically generating/storing SHSH2 files; it is able to determine the best course of action one can take and assist them throughout/after jailbreaking. Doing so results in a few significant revenue streams for the jailbreaking community - revenue streams that are funneled directly towards bounties directed by the jailbreak community.
Key points
  1. Increase jailbreaking popularity by making the process more "streamlined" and expand support options should a jailbreak attempt fail
  2. Provide tools to make managing a jailbreak easier
  3. Community funded Bounties
  4. A platform that's open-source
A platform that adapts to your device(s) and takes the stress out of jailbreaking
When you sign up the first thing you'll do is provide the model, which iOS version you're running, the ECID, and if you're currently jailbroken. All of this info will be encrypted using Amazon's KMS (more on that in the next section). With this info; we can have a dashboard capable of adapting to your device. This can help a user walk through the jailbreaking process, provide tweaks/utilities supported with their jailbroken version of iOS, and notifications to any new updates relating to those tools. Here's an example of how a jailbreaking process might work:
Imagine this Scenario:
As soon as you log in; you'll have a dashboard presented to you which will describe your device and display the options available to you. It will do this by looking at your current iOS version, the jailbreaking tools available, and your saved blobs.
Should the process fail at any point in time, and they are unable to recover; they will have the choice to either go to /jailbreak to request assistance or pay for additional assistance (more info about this in the "Funding" section below). Upon doing so, the interaction will be noted as a failed path to a jailbreak...affecting it's reliability score.
Account Privacy and Automated SHSH2 Generation
An important thing to note is that your account and device information will act as two separate entities. The ECID, current iOS version, jailbreak status, and SHSH2 files will be encrypted through Amazon's Key Management System (KMS). A UUID will act as the relation between your account and each device you add. However, the model of the device and the iOS versions your blobs support will remain unencrypted so it can check if you have any blobs missing - This avoids unnecessary calls to KMS.
How does it work?
Encrypting device information:
When you add a device onto your account, the first thing it'll do is send it to KMS to be encrypted. A unique "Data Key" will be randomly generated and that "Data Key" will then be used to encrypt the device information (a process handled by Amazon). The "Data Key" will then be encrypted by Amazon using a "Master Key" we'll never see. Visual representation.
SHSH2 files will be stored in S3 utilizing a similar method.
Storing Encrypted "Data Keys":
A database outside of AWS will contain the encrypted "Data Keys". This ensures that if AWS is impacted (through things like unauthorized account access); device data will remain encrypted and inaccessible.
Accessing Encrypted Data:
Once the data is decrypted through Amazon; it will be loaded into memory in a Lambda function and then thrown away. It will never sit around anywhere unencrypted.
I have no interest making a dime off of the community. Actually, quite the opposite. Any funds generated will first cover hosting/development costs, and the rest will go straight to the community (next section). To ensure transparency, the application could pull reports from the AWS Cost Explorer API and make them publicly available. Services mentioned below will be purchased using bitcoin (assuming volatility has calmed down when this is made available) and managed in an accountable manner.
I envision 3 different models:
  1. Unobtrusive Advertising - Using bitmedia
  2. TSS Tokens - Users will purchase tokens for automatic SHSH2 generation. Less than a dollar per - otherwise, a user can login and generate them without paying a dime.
  3. Failed Jailbreak Support - A market of verified jailbreakers who are interested in helping others needing immediate help getting out of a bind. Majority goes to the person providing assistance...small cut goes back into the community. "Verified Jailbreakers" can consist of those who've shown a clear understanding of jailbreaking and proven track-record of helping others in /jailbreak
When a service is ordered; the allotted community funds will be divided up using a weighted formula to bounties submitted by the community. The amount of funds allotted to each bounty will be determined through community demand.
Paying it forward
Though we do see bounties offered quite often on here; I believe at times we have a lot of folks in the jailbreaking community that sets high expectations towards security researchers/developers while at the same time offering very little reward. Don't believe me? Just look at twitter!
Through the centralization of the jailbreaking process in a responsible and trust worthy manner; you create a platform that helps everyone in some kind of way. More importantly, it opens up several streams of revenue for the community to grow as a whole.
The application will feature a platform similar to uservoice (though a bit stripped down) where the community will suggest bounties related to jailbreaking. Through the funds generated from helping people perform/maintain a jailbreak; the bounties would continue to grow in value until a developer fulfills the request. If it's fulfilled, the developer can either be awarded those funds...or contribute them to a bounty of their choosing. If a bounty is determined to be abandoned and/or has not been fulfilled within a reasonable amount of time; it will be removed and funds will be reallocated to other bounties.
Users can also donate directly to a bounty of their choosing, and in return be given TSS Tokens based on the value of their donation.
Proposed Timeline
  1. Basic Dashboard: Automatic generation of SHSH2 files
  2. Adaptive Dashboard: Jailbreak Assist (No support features)
  3. Advertising / Basic Bounty Features
  4. Examine community's response - Improve upon prior
  5. TSS Token Implementation / Expand Bounty Features
  6. Examine community's response - Improve upon prior
  7. Failed Jailbreak Support - Integration with Jailbreak Assist
  8. Examine community's response - Improve upon prior
  9. v1?
This application is designed to be completely serverless. Less time dealing with infrastructure will allow for more time spent developing the actual application. I chose AWS mainly because my familiarity with it...I am aware that other cloud providers likely have cheaper alternatives so it's not set in stone. Again, this is just an idea and this just identifies major back-end components.
TLDR: I have an idea for a centralized portal that makes jailbreaking an easier chore though adapting guides and the tools required to perform jailbreaks based upon your device. It does so by automatically backing up your blobs, knowing your current version of iOS, and the model number. It also features an "onboarding" feature should someone want to jailbreak but they're on 11.2.5 for example - providing advice up until a jailbreak is released. Should one become available...everything will be ready for you right when you log in. A few revenue streams are generated through this where (besides covering hosting costs) the money goes directly to bounties requested by the community. The ultimate goal is to encourage new people to come on board, and encourage developers/security analysts to participate in the jailbreaking community through financial incentives.
