Airdrops give crypto fans and bounty hunters alike a legit way to get free tokens and try out these services without having to buy anything.

An airdrop is a free way to get in on the ground floor with new ERC20 tokens.

Sometimes, when a company decides to create a new token, they choose to give away “free samples” to the public in exchange for getting involved with their push on social media. This could mean following them on Twitter or Facebook, posting in their Telegram group, or signing up for their email list. A few weeks or months later, the tokens are distributed to everyone who got involved as a way of saying “thank you.”

Airdrops are completely legitimate, run by the companies that create the tokens in the first place. They’re a win-win for both the businesses and the users. As with any usage token, they can be saved up and used later, or traded on an open market.

That depends. Most blockchain companies will not transfer tokens until the end of their ICO (Initial Coin Offering) crowd funding phase. Keep an eye on their telegram channels for more information, and for our notifications as well because we track them too.


ROX is the in-app token currency of Quarry. You receive them for your in-app efforts up-voting, commenting, and sharing posts about blockchain technology and cryptocurrency.


For starters, Quarry is the only application that allows you to share your airdrop referral codes in a safe and secure way. Use your ROX to submit them to us and we’ll share your airdrop links with all of your fellow Quarriors!

We’re working on more perks and benefits, tell us what you’d like to be able to do with your ROX by shooting an email over to support@quarry.rocks


In the past, there was a withdraw system based on in-app contributions (i.e. in-app activity that was beneficial to the Quarry community). We are in the process of updating the app with new and exciting ways to redeem your ROX, so stay tuned!


Never! Just kidding… it’s dependent on the success of the app!

It’s because your friends don’t know how to use links properly. After you’ve pulled them out of that rock they’ve been under and finished explaining the Internet of Things, have them install the app from your link. You might want to be babysitter as they do it — you know — just in case. This will not work if they’ve installed the app previously.

Tap on the crypto you’d like to send from your wallet screen and you will be prompted with a transfer screen. Certain cryptos are not readily transferable, and we’re working to expand this all the time. If you run into this problem, please contact help via support@quarry.rocks.


We currently process each one of your submissions by hand, in a shack; with crank-powered electricity. Our interns are the best and brightest, but even they hate doing this. In the future we will be able verify your applications in a more automated way — #TotallyNotRobots — but for now it creates jobs. Thanks for your understanding!

IF you believe you made a mistake in your submission, contact us through email at help@quarry.rocks with your telegram name (@boondoge) and your Facebook ID (facebook.com/TheRealBoondoge) — or whatever social media requirement we asked for (it changes)!


Simply put, a blockchain is a series (“chain”) of informational containers (“blocks”).

While this technology was described as far back as the 90s, it was mostly ignored until Satoshi Nakamoto used it to create Bitcoin in 2009. As it is used in Bitcoin, a blockchain functions as a distributed ledger that is open to anybody. When data has been added to a blockchain, it becomes very, very difficult to change it.

How does that work? Let’s look at a block.

Each block contains some data, the hash of the block, and the hash of the previous block. The data stored inside a block depends on the type of blockchain. The Bitcoin blockchain, for example, stores data about transactions, including a sending address, receiving address, and the amount of coins sent.

A block also has a hash, which is a kind of digital fingerprint. You can use a hash to identify a block and all of its contents, and it is always unique to that block. When a block is created, its hash is created, meaning that changing something inside the block will also cause the hash (fingerprint) to change.

What this means is that hashes are useful for detecting changes to blocks. Basically, if the hash is different than expected, we know that it is no longer the same block.

The third element in each block is the hash of the previous block. This effectively creates a chain of blocks — a blockchain — with each block pointing to a previous block.

This means that changing anything, on any block, makes all the following blocks suddenly invalid, since changing the data inside a block changes the hash, breaking the chain link with the next block.

Hypothetically, a computer could make a change to a block, then look “ahead” on the blockchain and calculate the hashes of all the following blocks, “tricking” the blockchain into believing the change. To mitigate against this, blockchains use a number of methods to effectively “slow down” the calculations of hashes. The most popular method (and the one used by Bitcoin) is called proof-of-work.

Proof-of-work is a mechanism that slows down the creation of new blocks. In the case of Bitcoin, it takes about 10 minutes to calculate the required proof-of-work and add a new block to the chain. This makes it very, very difficult to tamper with a block, because doing so requires that you (slowly) recalculate the proof-of-work for all the following blocks.

Already, this makes for a very secure method of storing data, but blockchains have one more method of security, and it is the most powerful of all.

Blockchains are distributed and decentralized.

Instead of keeping all of this data in one place, blockchains operate on peer-to-peer networks, allowing anyone to join. When someone joins the network, they get a full copy of the blockchain (called a “node”). When someone creates a new block, it is sent to every node on the network to ensure that it hasn’t been tampered with. If everything checks out, each node is updated to include the new block. The nodes in the network have to have a consensus, meaning that they have to agree about which blocks are valid and which aren’t. Blocks that are tampered with are going to be rejected by the network unless 51% of nodes agree.

Hypothetically, to change records on a blockchain, someone would need to:

  1. individually tamper with all the blocks on the chain,
  2. redo the proof-of-work for each individual block, and
  3. have control of 51% of the peer-to-peer network.

This is almost impossible to do, and it becomes more difficult as more people adopt the technology.

Blockchains are also constantly evolving. For example, some blockchains, such as the Ethereum blockchain, have developed smart contracts, which are a kind of simple program that is just as difficult to change as the data described above.

So, now you know what a blockchain is, how it has been designed for security, and what problems it solves.


A cryptocurrency is a digital form of money. In general, cryptocurrency can be purchased with fiat currency (“fiat” here meaning government-owned and distributed, such as US Dollars) and traded for other forms of cryptocurrency or fiat currency.

Cryptocurrencies are a blockchain technology, solving many of the problems of traditional monetary exchanges. They are secure, transferable, irreversible, anonymous, fast, global, debt-free, and permissionless.

Basically, cryptocurrencies are designed to be what traditional fiat currencies are supposed to be.

The most popular cryptocurrencies include Bitcoin and Ether, as well as hundreds of both well-known and obscure cryptocurrencies such as Dogecoin and Ripple.

Finally, many cryptocurrencies are built directly on the Ethereum blockchain, with the most popular standard being ERC20 tokens.


An ERC20 token is a special kind of cryptocurrency that is built on the Ethereum blockchain. Because Ethereum is built to allow for smart contracts, it functions as an environment where whole programs can be created and run. Because of this, many companies now are choosing to create their usage tokens in this way.

A token can be thought of like a movie ticket or concert pass. In general, you don’t just hand your money to a concert venue as you enter the building, but instead purchase a ticket ahead of time and use that on the day you actually want to attend the concert.

ERC20 tokens function much the same way. A company announces that their product or service is redeemable for tokens, which are available for sale in cash, and just like a traditional concert or movie ticket, these tokens can be given away or sold. This means that if you believe that a company’s services are going to become more valuable in the future, you might stock up on the tokens, hoping to sell them later. Alternatively, if you need access to a service now (for example, you want to take your date to a concert this weekend), you might be able to find the tokens (in this example, tickets) more cheaply on an open exchange.


Just as companies are able to create their own tokens atop the Ethereum blockchain, they are also able to build entire programs, called Decentralized Apps (Dapps), in much the same way.

Dapps function much the same as traditional apps on your mobile device or on the web (Facebook, for example, is one popular mobile app), except that they are decentralized. What this means is that they are not directly owned by any one individual, but by all of the people who use the blockchain. There is no central location where all the data is stored on servers, no single point of failure, no place for hackers to attack.

But honestly, most non-technical people don’t need to care about any of this.

Put simply, Dapps are the future of online applications, and right now they serve as an excellent proof of what can be built on a distributed blockchain.


Blockchain will do to the financial world what the internet did to the media world. If you consider the difference between how we access media today (YouTube, Netflix, Spotify, online news outlets, etc.) and how we accessed it 20 years ago (cable, Blockbuster, cassette tapes, etc.), it’s easy to see just how much better things are now because of easier and faster access.

Blockchain is the internet of money.

It is already changing the way that people send and receive transfers, increasing financial privacy, solving traditional banking problems (such as double-spending), and enabling the common person to have much more direct control of their finances.

The purpose of cryptocurrencies isn’t to get rich on the next boom, although it is possible. The purpose is to have greater access to and control of financial tools. And, if you aren’t interested in money, blockchain also allows for complex decentralized applications, which are more secure and less prone to misuse than traditional centralized applications (such as Facebook).

Simply, you should care because blockchain is the future.
