https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/188.8.131.52 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude

New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

Greetings. 🤗 Today we will tell you about the PYRK project and about its features. 💡 PYRK is a privacy centric cryptographic currency based on the work of Bitcoin, Dash, and Digibyte. 📌 Built for the community, we've taken some of the best features of the top utility coins to create a new coin which launched on May 12th, 2020. ⚙️ PYRK’s improvements include triple algorithm Proof of Work with Multishield difficulty adjustment, Masternodes, Private Send, Community Fund Governance, and Simple Tokens based loosely on the Color Coins protocol. 🔹 PYRK has borrowed from DASH all the best features. Fast work speed. The ability to deploy masternodes and the ease of mining, and all this at very low fees. 🔹 Multishield is a "difficulty retargeting" method to maintain the "average" block timing, by automatically changing the complexity of mining on the network. 🔹 Thanks to the PYRK’s Triple Proof-of-Work algorithm, it is possible to mine on different algorithms, including SHA256, Scrypt, and X11. Thus, it is very unlikely for a single miner to attain 100% of the hash rate of a single algorithm. 🔹 In PYRK, anonymity is the cornerstone, so we use a technology called PrivateSend, originally developed by DASH. PrivateSend decentrally mixes all your coins with strangers, giving newly generated addresses, allowing you to maximize transaction privacy. 🔹 You can run a masternode. In PYRK Masternodes are all paid from generated block rewards. The Masternode rewards start at block 10,000 and the master node network receives 20% of the block reward. 📢 Read more about the PYRK project and why it is worth investing in on our website: https://pyrk.org/ https://preview.redd.it/vwty1esxlej51.png?width=1200&format=png&auto=webp&s=c168950275250eeb05eb65adafa6dced51bded5b
Hello. 👋🏻 Today we will tell you about ACIS-mining and its 3 best algorithms. 📌 With the advent of ASICs for mining, it became possible to mine Bitcoin in much larger quantities than using video cards. ASIC is an integrated circuit specialized to solve a specific problem, in our case, only for bitcoin mining. These schemes are many times more profitable than video cards, because with more power (hash calculation speed) they consume much less energy. This served as a good reason to create a cryptocurrency mining business. 📌 In bitcoin and other blockchain systems, the complexity of mining depends on how quickly the miners find the block. Compared with the GPU and CPU, specialized #ASIC miners solve #PoW puzzles better and are therefore able to quickly find new blocks. 📌 Since PoW is still the preferred mining consensus mechanism, we propose to take a multiple algorithm approach. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: #SHA256, #Scrypt, and #X11. 🔹 The SHA-256 algorithm has a number of advantages over other information protection technologies. Over the years of use in the cryptocurrency industry, he has shown his resistance to various hacking attempts. 🔹 Scrypt is a cryptocurrency mining algorithm that was previously interesting to many single miners in view of its resistance to the so-called “hardware attack”. The speed of creating blocks in a Scrypt-based blockchain is about 30 seconds. The hashrate, like Ethash, is measured in Megahash per second. Scrypt, first of all, became popular due to its use in Litecoin #cryptocurrency. 🔹 X11 is an encryption algorithm in which eleven are used instead of one function. This means that this technology can provide a high degree of security, because in order to harm the system, an attacker will have to crack all 11 functions, which is very unlikely, because the changes made will be visible after breaking the first function, and developers will have a lot of time to protect the system before the hacker reaches the eleventh function. Since these miners are already in wide use, the distribution of mining should be fair and even. Furthermore, the use of three different algorithms results in a far less chance of any single person gaining a majority hash rate share. Lastly, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining.

Hi, everyone! 👋🏻 Today we will tell you a little bit about the PYRK ecosystem. As many of you might know, blockchain ecosystems are the groups of actors who interact with one another within the world of blockchain and with the surrounding off-chain world. You can ask why do we need that? This is why. First of all, it helps to build many technical and technological solutions. It provides an ability to build partnerships. Joining the network you’ll be able to enter the international market. And, of course, environmental development helps you to improve your business reputation and your status. 📌 PYRK is a privacy-centric cryptographic currency based on the work of Bitcoin, Dash, and Digibyte. 📌 Many modern cryptocurrencies use a single algorithm Proof-of-Work mechanism, which can lead to 51% attack avenues on currencies. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: SHA256, Scrypt, and X11. Thus, there is a far less chance of any single person gaining a majority hash rate share. 📌 Moreover, PYRK uses the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining. MultiShield is designed to let the difficulty "fall" very fast, in order that the chain doesn't freeze. 💡 A future improvement planned for Pyrk is Simple Tokens. This is similar to the SLP (Simple Ledger Protocol) used by Bitcoin Cash. 💪🏻 As you can see, the system is growing and developing very fast. Become a part of our community! Take advantage of our inventive and growing ecosystem!

Proof-of-Work vs Proof-of-Stake algorithms and why PYRK uses PoW
Hello, community! 👋🏻 In this post, we will tell you about Proof-of-Work and Proof-of-Stake algorithms and why PYRK uses PoW. 🔗 A large part of 2019 was discussed in the discussion of the pricing of the key digital assets, which slightly increased, slightly higher than before. 2020 began with the confirmation of the bullish trend, taking into account the increase in bitcoin in January at Z0%. At the same time, the process between Proof-of-Work and Proof-of-Stake (proof of share) did not complete. Emotional gain increased by the approximation of the Ethereum switch from the PoW protocol to the PoS protocol. 🔗 Coins with PoW support are mined in the sector, having a colossal share of 82.92% and a cumulative market capitalization of about $ 213, 5 billion. The predominance of market capitalization on PoW is ensured by the fact that the bitcoin dodu accounts for 65% of the total market capitalization of crypto assets. Its main advantages of PoW are protection against DoS attacks and the low impact of the miner’s cryptocurrency share on mining opportunities. 🏆 PYRK Proof-of-Work triple algorithm ✅ Since PoW is still the preferred mining consensus mechanism, PYRK proposes to take a multiple algorithm approach. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: SHA256, Scrypt, and X11. ✅ Since these miners are already in wide use, the distribution of mining should be fair and even. Furthermore, the use of three different algorithms results in a far less chance of any single person gaining a majority hash rate share. Lastly, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining. ✅ The idea of multi-algorithm originated in Digibyte. Splitting the mining into three different algorithms effectively splits the amount of work performed by each algorithm to 33% of the total network hashrate. This means that any pool or miner mining can only achieve 33% of the total hashrate even if they are mining 100% of the hash rate of a single algorithm. It is an exceedingly unlikely case that a single miner attains 100% of the hash rate of a single algorithm, especially as the number of miners and pools grow with the network. The triple algorithm approach helps to further protect the network from bad actors while also providing the preferred Proof-of-Work mechanism. Read more about PYRK project and its Proof-of-Work triple algorithm in our Whitepaper: https://www.pyrk.org/Pyrk-Whitepaper.pdf And on our website: https://www.pyrk.org https://preview.redd.it/jmkjz2am47051.png?width=1200&format=png&auto=webp&s=8c4080d36769f7a953fdb436510e97b646e78d1d
Hello, community! 👋🏻 In this post, we will tell you about Proof-of-Work and Proof-of-Stake algorithms and why PYRK uses PoW. ⛏ Proof of work allows the blockchain to remain “clean”, allows the entire community to compete to verify the validity of transactions, and makes attacks on the system very costly. But is this cost of attack justified? Aste argues that it should be sufficient to make the double-spend attack too costly. ⛏ A double spend attack can occur in a situation where an attacker tries to send the same bitcoin to two different users. In such a case, the attacker would try to spend as many bitcoins as possible twice. This number is limited by the number of transactions that can fit in a block, which in value terms is currently about $ 2 million. ⛏ A transaction involving more than the total cost of transactions in the block will attract attention from the network. This puts a real limit on the size of a double spend of about $ 2 million. And although the duplication of transactions can be repeated several times sequentially or in parallel, we will neglect it in this calculation. 🏆 PYRK Proof-of-Work triple algorithm 🔹 PYRK takes a multiple algorithm approach. We propose to use algorithms which have had ASIC miners for quite some time. These are: SHA256, Scrypt, and X11. 🔹 Since these algorithms are already in wide use, the distribution of mining should be fair and even. 🔹 There’s a far less chance of any single person gaining a majority hash rate share when using three different algorithms simultaneously. 🔹 Also, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining. 💡 The idea of multi-algorithm originated in Digibyte. Splitting the mining into three different algorithms effectively splits the amount of work performed by each algorithm to 33% of the total network hashrate.

Hey shibes, I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts! Feel free to add information to that thread or correct me if I did any mistake.
You downloaded the core wallet
Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here. Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.
You downloaded a GPU/CPU miner
Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!
Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain." - langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!
Mining solo versus pool
So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.
Buying an ASIC
You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...
You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.
Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc. Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same. Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.
Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!
Folding at Home (Doge)
Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much. Thanks for reading _nformant
Today, in about 30 minutes or less from now, RandomX will be activated on Monero as part of its network protocol upgrade, so this seems like a good moment to share this timeline. It’s like the raw material for writing the history of ASIC resistant proof-of-work algorithms. If you think it’s incomplete, let me know what you’d like to add. I didn’t include Monero ASICs or FPGAs that weren’t publicly released, since it would be difficult to pin down a date.

My late night 1/2 baked idea to fix bitcoin + private asic farm issues
Link to topic that inspired this idea: http://www.reddit.com/Bitcoin/comments/1tpo2p/is_anyone_else_concerned_about_ghashio/ceaeit2 Anyway, as satoshi himself said there is no reason the algorithm cant be changed by adding "if block height is > X use NEWALGO" So the detraction (for many) of this idea is that their million dollar investments into private asic farms / individual purchases of mining hard are rendered useless, network may suffer from reduced security etc etc etc. So here is my simple solution, excuse the crappy pseudo code its late, and Im seriously hung over from the family xmas lunch :P
I feel this idea has many benefits such as: + the network retains a large amount of power. + Scrypt (with good parameters) is very asic resistant. + building longer chains of successive blocks to double spend requires double the hardware (at least) due to every second block not being able to be crunched with highly efficient asics. Also, merry xmas/ happy holidays everyone :) edit: this solution would require 2 difficulties due to the difference in nature of the 2 algos but imho it would be a trivial addition.
I noticed that I got my confirmations very fast. At blockexlorer I saw that in the past 80 minutes there where 20 blocks mined. (4 minutes average a block) http://blockexplorer.com/ Blockchain.info showed me that the network hashing rate went up by ~25% in the past 24 hours. https://blockchain.info/charts/hash-rate?timespan=30days Is this caused by a new generation ASIC miners or is something else going on?
Are multiple mining algorithms possible with Monero? Can RandomX be added to the system instead of replacing what's in place? Not sure what headaches it would bring for the security part of Monero.
Is it possible for Monero to have multiple mining algorithms like Digibyte (DGB)? The idea of keeping the large group of GPU miners to help keep the network decentralized and expand with Random X to bring in a large number of CPU miners. Also, if for some reason Random X doesn't workout we still have current algorithm that gets updated every 6 months. DGB borrowed from Huntercoin which mines 2 algorithms and Myriad that has 5 mining algorithms. Could Monero do the same? I believe DGB also adjust algorithms to keep incentives equal. Digibyte - Reddit Decentralization Decentralization is an important concept for the block-chain and cryptocurrencies in general. This allows for a system which cannot be controlled nor manipulated no matter how large the organization in play or their intentions. DigiByte’s chain remains out of the reach of even the most powerful government. This allows for people to transact freely and openly without fear of censorship.Decentralization on the DigiByte block-chain is assured by having an accessible and fair mining protocol in place – this is the multi-algorithm (MultiAlgo) approach. We believe that all should have access to DigiByte whether through purchase or by mining. Therefore, DigiByte is minable not only on dedicated mining hardware such as Antminers, but also through use of conventional graphics cards. The multi-algorithm approach allows for users to mine on a variety of hardware types through use of one of the 5 mining algorithms supported by DigiByte. Those being:
Please note that these mining algorithms are modified and updated from time to time to assure complete decentralization and thus ultimate security.The problem with using only one mining algorithm such as Bitcoin or Litecoin do is that this allows for people to continually amass mining hardware and hash power. The more hash power one has, the more one can collect more. This leads to a cycle of centralization and the creation of mining centers. It is known that a massive portion of all hash power in Bitcoin comes from China. This kind of centralization is a natural tendency as it is cheaper for large organisations to set up in countries with inexpensive electricity and other such advantages which may be unavailable to the average miner.DigiByte mitigates this problem with the use of multiple algorithms. It allows for miners with many different kinds of hardware to mine the same coin on an even playing field. Mining difficulty is set relative to the mining algorithm used. This allows for those with dedicated mining rigs to mine alongside those with more modest machines – and all secure the DigiByte chain while maintaining decentralization. Let's give every nation a chance to mine
So, I've been talking to a few miners about where the network difficulty is headed, now that ASICs are taking over the network completely. It got me curious about what the similarities might be between the velocity of hashrate increases during the same time period in Bitcoin's lifespan, and if there were...what we might be able to expect as technology improves between now and this time next year, based on what has happened to Bitcoin. I consulted http://bitinfocharts.com/ for the evidence. ASICs started shipping for Bitcoin toward the end of January of 2013, almost exactly as was the case for Litecoin this year. Here is a chart which shows the growth curve of network hashrate for both, between February 1st and August 1st (today). I find it incredibly interesting that they're so similar in velocity. http://imgur.com/9hkEib0 Bitcoin Feb 1, 2013 - Aug 1, 2013 21.8TH - 271.19TH (1,143% increase) Litecoin Feb 1, 2014 - Aug 1, 2014 80.63GH - 742GH (820% increase) There are a lot more Scrypt coins in existence than there were SHA-256 coins, at the same time in Bitcoin's development. Be that as it may, the percentage increases between the two, during the same time period of their development, are very close. So...given the similarities in the trajectory, where might Litecoin be headed over the rest of the year? Let's look at how Bitcoin finished out 2013. http://imgur.com/cuNWJi8 Bitcoin Aug 1, 2013 - Dec 31, 2013 271TH - 10,910TH Holy. Crap. In the space of five months, from summer to New Year's, Bitcoin increased 3,925% in its network hashrate. What if the trend continues, and Litecoin follows the same trajectory and experiences a similar gain in network hashrate? Litecoin Possible Hashrate Gain: Aug 1, 2013 - Dec 31, 2014 742GH - 29.8TH When the Bitcoin network had reached 29.8TH/s, the difficulty was at 244,000. Gulp Now, granted...my math is not the strongest in the world...so hopefully I haven't screwed any of these numbers up and feel free to correct me if I'm wrong on any of it. But...it's looking to me like if the trend continues, Litecoin's difficulty is going to go ballistic over the second half of 2014...and then supernova in 2015. The difference is, I believe that the ASIC devices for Scrypt will eventually hit a wall that SHA-256 devices didn't, due to the memory requirements and the limits of how small die sizes can shrink. It actually IS still ASIC-resistant, but it remains to be seen, at which point that resistance will assert itself. Anyway, if you don't think this is going to have an affect on miner selling behavior or the price of the coin...I disagree. (Edited to correct some bad math. Shame on my public school education.)

Q: How many cryptocurrencies does that cover? A: ¯\(ツ)/¯ We stopped counting when we reached 1,000.
Every week we put on an event called Free Hash Friday, and don’t call the DEA because we're not giving away weed! Maybe Canada can help you with that, but here's the general rundown for Free Hash Friday: The AIOMiner team sends out a tweet every week with directions in an image, such as this one. Follow the directions in the tweet where it says "To Win" with the arrows. Once you've completed those three steps, your twitter handle will be inputted into a spreadsheet (that is shared with the public) and you'll be assigned a number in the order that you're inputted. You have until 8pm US Pacific Time (GMT -7) to enter. At 8pm, the spreadsheet will be updated one final time and the drawing will begin immediately in the AIOMiner discord channel. You'll notice on the spreadsheet that you have a number next to your twitter handle. We have a bender bot that is able to generate a random number given the upper and lower limit. If your number is the randomly generated number, you win! Typically we pair with a coin, as you can see, who puts up some to giveaway and we have multiple winners. If we don't have a coin to give away, The AIOMiner team will simply start mining on behalf of the winner for 24 hours and mine any gpu-mineable coin of their choice. And that's pretty much it! So, follow our twitter and be on the lookout for the next Free Hash Friday!
What else should I know about AIOMiner?
We are fully committed to keeping mining free for everyone, but it does cost some money to keep the servers up and running. So, we're planning on releasing some "premium" features in the near future that will take the mining experience to the next level. Until December 1st, we will allow users to donate/purchase a lifetime premium account. With this account you will gain access to AIOMiner and all of the premium features that we release as well as any future product we make for free. This is only for a limited time, so if you're in the mining game for the long haul, it is definitely worth it. After December 1st, we will open up the premium features on a membership/monthly subscription basis. So, get it while it's hot!
Other than that, enjoy the software, enjoy the giveaways and come participate in the community:
Thank you again to everyone who has helped make AIOMiner what it is today!
