SUPPORT A FAIRER FINANCIAL SYSTEM
Without the hardworking independent developers who build and improve the Bitcoin Cash (BCH) network itself, our mission of helping the world access a fairer financial system wouldn’t be possible.
What is Bitcoin Cash?
Bitcoin cash is a cryptocurrency created in August 2017, from a fork of Bitcoin. Bitcoin Cash increases the size of blocks, allowing more transactions to be processed. The cryptocurrency underwent another fork in November 2018 and split into Bitcoin Cash ABC and Bitcoin Cash SV (Satoshi Vision). Bitcoin Cash is referred to as Bitcoin Cash because it uses the original Bitcoin Cash client.
Understanding Bitcoin Cash
The difference between Bitcoin and Bitcoin Cash is philosophical.
As proposed by Bitcoin inventor Satoshi Nakamoto, Bitcoin was meant to be a peer-to-peer cryptocurrency that was used for daily transactions. Over the years, as it gained mainstream traction and its price surged, Bitcoin became an investment vehicle instead of a currency. Its blockchain witnessed scalability issues because it could not handle the increased number of transactions. The confirmation time and fees for a transaction on bitcoin’s blockchain surged. This was mainly due to the 1MB block size limitation for bitcoin. Transactions queued up, waiting for confirmation, because blocks could not handle the increase in size for transactions.
Bitcoin Cash proposes to remedy the situation by increasing the size of blocks to between 8 MB and 32 MB, thereby enabling processing of more transactions per block. The average number of transactions per block on Bitcoin is between 1,000 and 1,500. The number of transactions on Bitcoin Cash’s blockchain during a stress test in Sep 2018 surged to 25,000 per block.
Major proponents of Bitcoin Cash, such as Roger Ver, often invoke Nakamoto’s original vision of a payment service as reason to increase block size. According to them, the change in bitcoin’s block size will enable bitcoin’s use as a medium for daily transactions and help it compete with multinational credit card processing organizations, such as Visa, which charge high fees to process transactions across borders.
Bitcoin Cash also differs from bitcoin in another respect. It does not incorporate Segregated Witness (SegWit), another solution proposed to accommodate more transactions per block. SegWit retains only information or the metadata relating to a transaction in a block. Typically, all details pertaining to a transaction are stored in a block.
Ideological and block size differences apart, there are several similarities between Bitcoin and Bitcoin Cash. Both use the Proof of Work (PoW) consensus mechanism to mine new coins. They also share the services of Bitmain, the world’s biggest cryptocurrency miner. The supply of Bitcoin Cash is capped at 21 million, the same figure as Bitcoin. Bitcoin Cash also started off using the same difficulty algorithm – Emergency Difficulty Adjustment (EDA) – which adjusts difficulty every 2016 blocks or roughly every two weeks. Miners took advantage of this similarity by alternating their mining activity between Bitcoin and Bitcoin Cash. While it was profitable for miners, the practice was detrimental to increasing supply of Bitcoin Cash in the markets. Hence, Bitcoin Cash has revised its EDA algorithm to make it easier for miners to generate the cryptocurrency.
History of Bitcoin Cash
In 2010, the average size of a block on Bitcoin’s blockchain was less than 100 KB and the average fee for a transaction amounted to a couple of cents. This made its blockchain vulnerable to attacks, consisting entirely of cheap transactions, that could potentially cripple its system. To prevent such a situation, the size of a block on bitcoin’s blockchain was limited to 1 MB. Each block was generated every 10 minutes, allowing for space and time between successive transactions. The limitation on size and time required to generate a block added another layer of security on bitcoin’s blockchain.
But those safeguards proved to be a hindrance when bitcoin gained mainstream traction on the back of greater awareness of its potential and enhancements to its platform. The average size of a block had increased to 600K by Jan 2015. The number of transactions using Bitcoin surged, causing a buildup of unconfirmed transactions. The average time to confirm a transaction also moved upwards. Correspondingly, the fee for transaction confirmation also increased, weakening the argument for bitcoin as a competitor to expensive credit card processing systems. (Fees for transactions on bitcoin’s blockchain are specified by users. Miners typically push transactions with higher fees to the front of the queue in order to maximize profits.)
Two solutions were proposed by developers to solve the problem: increase the average block size or exclude certain parts of a transaction to fit more data into the blockchain. The Bitcoin Core team, which is responsible for developing and maintaining the algorithm that powers bitcoin, blocked the proposal to increase block size. Meanwhile, a new coin with flexible block size was created. But the new coin, which was called Bitcoin Unlimited, was hacked and struggled to gain traction, leading to doubts about its viability as a currency for daily transactions.
The first proposal also drew sharp and diverse reactions from the bitcoin community. Mining behemoth Bitmain was hesitant to support Segwit implementation in blocks because it would affect sales for its AsicBoost miner. The machine contained a patented mining technology that offered a “shortcut” for miners to generate hashes for crypto mining using less energy. However, Segwit makes it more expensive to mine Bitcoin using the machine because it makes transaction reordering difficult.
Amidst a war of words and staking out of positions by miners and other stakeholders within the cryptocurrency community, Bitcoin Cash was launched in July 2017. Each Bitcoin holder received an equivalent amount of Bitcoin Cash, thereby multiplying the number of coins in existence. Bitcoin Cash debuted on cryptocurrency exchanges at an impressive price of $900. Major cryptocurrency exchanges, such as Coinbase and Itbit, boycotted Bitcoin Cash and did not list it on their exchanges.
But it received vital support from Bitmain, the world’s biggest cryptocurrency mining platform. This ensured a supply of coins for trading at cryptocurrency exchanges, when Bitcoin Cash was launched. At the height of cryptocurrency mania, Bitcoin Cash’s price skyrocketed to $4,091 in December 2017.
Paradoxically enough, Bitcoin Cash itself underwent a fork slightly more than a year later due to the same reason it split from Bitcoin. In Nov 2018, Bitcoin Cash split into Bitcoin Cash ABC and Bitcoin Cash SV (Satoshi Vision). This time around, the disagreement was due to proposed protocol updates that incorporated the use of smart contracts onto bitcoin’s blockchain and increased the average block size.
Bitcoin Cash ABC uses the original Bitcoin Cash client but has incorporated several changes to its blockchain, such as Canonical Transaction Ordering Route (CTOR) – which rearrange transactions in a block to a specific order.
Bitcoin Cash SV is led by Craig Wright, who claims to be the original Nakamoto. He rejected the use of smart contracts on a platform that was meant for payment transactions. The drama prior to the latest hard fork was similar to the one before forking Bitcoin Cash from Bitcoin in 2017. But the end has been a happy one as more funds have flowed into the cryptocurrency ecosystem due to the forking and the number of coins available to investors has multiplied. Since launching, both cryptocurrencies have garnered respectable valuations at crypto exchanges.

THE SAFE RIDE FOUNDATION
“The Safe Ride Foundation is one of Maryland’s leading organizations taking a stance against driving while intoxicated. Our mission is to implement and replicate programs that will not only provide our public with the education on the dangers of intoxicated driving, but also a faithful and reliable alternative to those dangers, and a haven of support for victims as well as the families of victims.
The Safe Ride Foundation, otherwise known as S.O.S. Safe Ride is a non-profit organization based in the bustling city of Frederick, Maryland.
We are adults who, just like you, enjoy having a great time out. However we also take immense pride in making responsible decisions when doing so. This includes both during and after a night out. Our organization was founded by individuals who grew up in this area, who understand its people, its culture, and its social indulgence habits. We believe that every organization must define four things for itself and others in order to truly be successful: its Mission, its Dream, its Vision, and its Purpose. Below we have outlined each of these, in an attempt for the public to truly understand what we’re aiming to accomplish with The Safe Ride Foundation.
To implement and replicate programs that will provide our public with the education on the dangers of drunk driving, a faithful and reliable alternative to those dangers, and a haven of support for victims as well as the families of victims.
To shift the drinking culture in our area and parts beyond to reflect a higher sense of accountability and responsibility as it pertains to driving while intoxicated.
To effectively create the “Uber” of designated driving with a charitable infrastructure.
To ensure that every single intoxicated bar patron in our area arrives home safely, and not behind the wheel of a vehicle.

ANIMAL HOPE BULGARIA BURGAS
Animal Hope Bulgaria – Burgas is an organization that operates entirely through volunteers, without receiving state or municipal funding, which means that the only way to help our animals is with your donations and support.
Every day we are overwhelmed by dozens of reports of animals in distress, signals that all we can do is share to our page due to the shortage of accommodation and financial resources for their treatment and nutrition.
Since April 2016, we have been in a particularly dire financial situation. We bought land to build a crisis center but the project was frozen due to lack of funds. At the moment, we are barely able to buy the weekly animal feeds and cover the bills in veterinary clinics. Unfortunately, there is a real danger of having to put the animals back on the streets, or worse.
In order to respond to signals, to save, to heal, to nourish, to care for and to provide shelter to all those homeless animals WE need YOU! We need your help and support! Because YOU are the engine of our organization. We give them our days and nights, our love, attention and personal funds… but considering their number, our means are extremely inadequate.
The site is maintained by two people, one of whom takes care of the animals daily, and we also go to work. We do not have the physical ability to constantly share to pages and groups. We are deeply disappointed that our page, as well as our personal profiles, are overwhelmed by constant signals in which we are required to take in another animal, and at the same time, our appeals for help are ignored. We want to help each and every animal but we can’t.
We cannot describe with words the feeling of dozens of big sad eyes looking hopefully at you, or the lump stuck in your throat because you cannot afford to take them in… and yet there they are – waiting and hoping. And since no one should ever go to sleep hungry, no one should suffer and be in pain, our loans and obligations grew bigger and bigger and it reached the point of where we can no longer afford to go further.
We live day by day with the food donated to us. In one week, our dogs consume 70 kg of dog food and our cats about 25 kg of cat food. We have liabilities of over €1,500 to veterinary clinics. We also pay €250 for rent every month.
We do everything for them, and you can do something for them too!
To anyone who decides to help – thank you! We also thank you on behalf of all those animals that, with the help of each big heart that decides to donate, will be fed and sheltered tonight. All they have is us – the people who love them and care for them!

The Tor network is a group of volunteer-operated servers that allows people to improve their privacy and security on the Internet. Tor’s users employ this network by connecting through a series of virtual tunnels rather than making a direct connection, thus allowing both organizations and individuals to share information over public networks without compromising their privacy. Along the same line, Tor is an effective censorship circumvention tool, allowing its users to reach otherwise blocked destinations or content. Tor can also be used as a building block for software developers to create new communication tools with built-in privacy features.
Individuals use Tor to keep websites from tracking them and their family members, or to connect to news sites, instant messaging services, or the like when these are blocked by their local Internet providers. Tor’s onion services let users publish web sites and other services without needing to reveal the location of the site. Individuals also use Tor for socially sensitive communication: chat rooms and web forums for rape and abuse survivors, or people with illnesses.
Journalists use Tor to communicate more safely with whistleblowers and dissidents. Non-governmental organizations (NGOs) use Tor to allow their workers to connect to their home website while they’re in a foreign country, without notifying everybody nearby that they’re working with that organization.
Groups such as Indymedia recommend Tor for safeguarding their members’ online privacy and security. Activist groups like the Electronic Frontier Foundation (EFF) recommend Tor as a mechanism for maintaining civil liberties online. Corporations use Tor as a safe way to conduct competitive analysis, and to protect sensitive procurement patterns from eavesdroppers. They also use it to replace traditional VPNs, which reveal the exact amount and timing of communication. Which locations have employees working late? Which locations have employees consulting job-hunting websites? Which research divisions are communicating with the company’s patent lawyers?
A branch of the U.S. Navy uses Tor for open source intelligence gathering, and one of its teams used Tor while deployed in the Middle East recently. Law enforcement uses Tor for visiting or surveilling web sites without leaving government IP addresses in their web logs, and for security during sting operations.
The variety of people who use Tor is actually part of what makes it so secure. Tor hides you among the other users on the network, so the more populous and diverse the user base for Tor is, the more your anonymity will be protected.
Using Tor protects you against a common form of Internet surveillance known as “traffic analysis.” Traffic analysis can be used to infer who is talking to whom over a public network. Knowing the source and destination of your Internet traffic allows others to track your behavior and interests. This can impact your checkbook if, for example, an e-commerce site uses price discrimination based on your country or institution of origin. It can even threaten your job and physical safety by revealing who and where you are. For example, if you’re travelling abroad and you connect to your employer’s computers to check or send mail, you can inadvertently reveal your national origin and professional affiliation to anyone observing the network, even if the connection is encrypted.
How does traffic analysis work? Internet data packets have two parts: a data payload and a header used for routing. The data payload is whatever is being sent, whether that’s an email message, a web page, or an audio file. Even if you encrypt the data payload of your communications, traffic analysis still reveals a great deal about what you’re doing and, possibly, what you’re saying. That’s because it focuses on the header, which discloses source, destination, size, timing, and so on.
A basic problem for the privacy minded is that the recipient of your communications can see that you sent it by looking at headers. So can authorized intermediaries like Internet service providers, and sometimes unauthorized intermediaries as well. A very simple form of traffic analysis might involve sitting somewhere between sender and recipient on the network, looking at headers.
But there are also more powerful kinds of traffic analysis. Some attackers spy on multiple parts of the Internet and use sophisticated statistical techniques to track the communications patterns of many different organizations and individuals. Encryption does not help against these attackers, since it only hides the content of Internet traffic, not the headers.
Tor can’t solve all anonymity problems. It focuses only on protecting the transport of data. You need to use protocol-specific support software if you don’t want the sites you visit to see your identifying information. For example, you can use Tor Browser while browsing the web to withhold some information about your computer’s configuration.
Also, to protect your anonymity, be smart. Don’t provide your name or other revealing information in web forms. Be aware that, like all anonymizing networks that are fast enough for web browsing, Tor does not provide protection against end-to-end timing attacks: If your attacker can watch the traffic coming out of your computer, and also the traffic arriving at your chosen destination, he can use statistical analysis to discover that they are part of the same circuit.
Providing a usable anonymizing network on the Internet today is an ongoing challenge. We want software that meets users’ needs. We also want to keep the network up and running in a way that handles as many users as possible. Security and usability don’t have to be at odds: As Tor’s usability increases, it will attract more users, which will increase the possible sources and destinations of each communication, thus increasing security for everyone. We’re making progress, but we need your help. Please consider running a relay or volunteering as a developer.
Ongoing trends in law, policy, and technology threaten anonymity as never before, undermining our ability to speak and read freely online. These trends also undermine national security and critical infrastructure by making communication among individuals, organizations, corporations, and governments more vulnerable to analysis. Each new user and relay provides additional diversity, enhancing Tor’s ability to put control over your security and privacy back into your hands.
