Crypto sauce space algo
Viewing cryptocurrency miners as a problem to solve instead of a resource to tap is the greatest failure of imagination in the space today. It is remarkable given the ethos of decentralization and the level of passion and investment from the mining community. So how did these early-adopters become uncomfortable topics at developer project meetings and afterthoughts in the media? For many early adopters, mining was their introduction to the crypto space. Especially with strong community advocacy and die-hard support.

Google Tez’s 50 million installs secret sauce
Bitcoin was designed to work against the most powerful of adversaries, and boy — did the adversary show up! Then the Chinese government banned it. There are anecdotal accounts from people on the ground are seeing Bitcoin mining operations being shut down by law enforcement agents. And there are similar accounts from people on the ground elsewhere in the world where containers full of mining hardware are being shipped to, lock, stock and barrel.
I have a copy of the Bitcoin blockchain on my computer, and could actually run the numbers myself and see that the production of Bitcoin blocks slowed down dramatically. Bitcoin blocks, on an average, are supposed to be generated once every seconds. But you can see the spike in this number on the graph towards the end, going all the way up to seconds.
This means that during that period, the total number of active miners went down dramatically, and that led to the inter-block average-gap increasing equally dramatically from seconds to seconds. Putting the anecdotal and canonical sources of data together, we can be reasonably certain that the Chinese mining ban lead to a global drop in Bitcoin mining.
Not really. Miners come, miners go — Bitcoin chugs along. That is what it is designed to do. Bitcoin targets a block production rate of seconds per block. Similarly, if its value went down or if governments kicked them out , miners would leave the system, and blocks would arrive much slower than seconds.
The block production rate on either side of would persist, and reflect the total number of miners in the system. No matter how many miners are in the system, it always takes around seconds to mine a block. Before we get to the difficulty adjustment algorithm, we have to first understand why keeping the inter-block interval of seconds is important. Bitcoin works because everyone can check whether their perceived ownership of their own Bitcoin is fact or fiction.
Where is this data? How big is it? How do I access it? It includes all transaction from the genesis block onwards - from January But storing everything with everyone sounds crazy - and to be honest, it is crazy. Bitcoin prefers the opposite: self-validation. So, if we accept the crazy idea that everyone stores a copy of the blockchain, we have a fundamental tradeoff - the blockchain cannot get very big by growing very fast.
It also cannot stay static: new transactions need to be added every so often to facilitate economic activity. Currently, the blockchain is around GB, and growing at around 50 GB per year. If it grows too fast, not everyone will be able to hold their own copy. Under these constraints, Satoshi decided that a 1MB block every 10 minutes is a good tradeoff. To keep this tradeoff constant, blocks cannot be generated slower or faster.
Remember that a miner who generates a new block gets to keep the newly minted Bitcoin that comes out of each block. So, if the value of Bitcoin goes up, expect more miners to materialize. To accommodate this, Satoshi designed a simple algorithm that makes mining harder or easier depending on how long it takes to generate the previous blocks. This number controls how hard or easy it is to mine a block. This difficulty number is then adjusted lower by the same factor X.
If the time taken to mine the previous blocks was lower, the difficulty number is adjusted upwards — again by the factor X. The genius, as they say, is in the simplicity of it. The reduced difficulty made it easier for the remaining online Bitcoin miners to start generating blocks every 10 minutes again. The next block average was seconds.
Difficulty has always gone up — to accommodate this increase in value. So, how does this difficulty number actually make it easier or harder to mine a Bitcoin block? You double hash data from the block you want to generate, and check if that hash value is less than the target on the right hand side of the equation. I need to keep trying the function again and again with different block-data to hit gold. If the difficulty number goes up, the mining target goes down, and finding block-data that double-hashes to a number lower than that target gets harder.
It happens only once every 6 times. If difficulty were to reduce, the target would move to a number less than or equal to 2. That happens every 3 times — mining just got easier. Why go into the nitty gritty details of this function, with all the associated arithmetic and probability? I want to get into the properties that this unique function has, that makes it ideal for Bitcoin mining - and resisting nation state attacks. Parameterizability : The function provides very fine degree of control over how much harder or easier we want the function evaluation to be.
If you increase or decrease the difficulty number, the function becomes easier or harder to evaluate, respectively. Each run of the function is what is called a Bernoulli trial — with the odds of hitting gold the same no matter how many times you have tried in the past.
This makes sure that larger miners have no other advantage than just the larger chance of producing a block. The other incredible advantage of Memorylessness is that a miner can be turned off, put in a container, shipped elsewhere and plugged back in.
The only loss the miner incurs is the Bitcoin that could have been mined in that interim time when the machine was turned off. Shutting down something abruptly, without needing to store any state of progress, and starting elsewhere without any extraneous loss is not that common. This allows Bitcoin miners to be incredibly mobile and seek out the cheapest electricity wherever it exists. They are, in the true sense, plug-and-play.
Hard to compute, but easy to verify : To get the double-hash value which is under the target needs millions of trials of the function. But once someone finds it, the rest of us can verify it immediately with just a single iteration of the function. This, again, makes decentralization possible — where all of us can run the Bitcoin software on our computers and check that the miners are doing the right thing.
Replacing this function is not that easy. Most attempts have kept the general idea, and have tinkered with the specifics. Yet another instance of Bitcoin living up to its promise of being designed to last forever. This self-adjusting nature of Bitcoin - that makes it change itself based on market conditions, with no one central entity being in charge - separates it from all other forms of money.

The Men Who Stare at Charts
Mercy Corps Ventures , the venture capital arm of Mercy Corps, invests in startups building climate resilience and financial resilience for communities across the world. Read on to learn about the role our ventures play in building a world where everyone can prosper. Exposure to climate shocks and food insecurity is high for those living in the tropics, with many of the most vulnerable at the front lines of both risks. If the needs of these populations are ignored, these pressures will only lead to further food insecurity, conflict, and displacement. The U. These farmers, their supporting vendors, and the food systems that depend on them function without weather forecasting tools tailored to their needs, and the impact on the market low and inconsistent food supply, low yields and loss of income is significant. This will be magnified by climate change as it intensifies already turbulent weather in the tropics, and as global demand on food systems increases. This reality makes access to accurate weather forecasts arguably the most important tool for smallholder farmers to increase their resilience to shocks and help stabilise income, but the science involved to predict a tropical atmosphere is complex.
Apriori Algorithm in Machine Learning
ByteDance has long been a proponent of content recommendation systems, and uses it on other products, such as the popular news aggregator Jinri Toutiao. Today it is the most downloaded app in the world, proving so popular that it has become a flashpoint in the escalating US-China tech war, which was previously focused on heavy-duty areas such as chips and 5G networks. Washington has demanded a forced divestment of TikTok in the US from its Chinese owner ByteDance on concerns over the safety of personal data. But updated export controls from Beijing last week — which cover two key technologies used by the short video app — have cast an added shroud of uncertainty over the sale.

A strong community is the lifeblood of your cryptocurrency startup. The startups emerging in the cryptocurrency space have many common elements of companies that are driven by communities. It is quite practical to create a sustainable competitive advantage by building a highly motivated community of users who are investing in the project. And when the project succeeds they users would cherish their sense of ownership. Especially in the case of the cryptocurrency startups, the project supporters have skin in the game and a community can unlock the potent network effect to scale the project. One key factor to consider in the case of the crypto community is that, although the startup is highly technical, the community is purely people-centric. This means communities are not driven by algorithms and programming.

Good morning! This Tuesday, leaked documents hint at more than meets the eye at ByteDance, Ubisoft offers a mea culpa, and New York is rolling out new vaccine mandates. But none of this is new. Retention, use time, number of likes and comments: These are the types of numbers every website or app analyzes to make informed business decisions.
Much of the financial world is all abuzz over the 50th annual letter to shareholders of Berkshire Hathaway, released this past weekend. Let me save you some time: No, you are not Warren Buffett. And, with apologies to Taylor Swift, you are never, ever, ever getting to a place where you invest like him. Why is that? Because Buffett has many things going for him that you do not, and likely will never, ever possess.
For well over a century, no asset class has more consistently built wealth for investors than stocks. But in recent years, stock gains haven't been able to hold a candle to the jaw-dropping increases witnessed in the cryptocurrency space. Despite these enormous gains, cryptocurrency projects that offer competitive advantages, differentiation, and real-world appeal still have the potential to head considerably higher.
