What is Bitcoin Mining Difficulty
wafflepool.com - An auto switching scrypt coin mining pool
WafflePool is a multi-coin (scrypt) mining pool. Point your miner to WafflePool with a Bitcoin address as your username, and we take care of automatically mining the most profitable coin at all times, converting the earnings from each coin into Bitcoins, and paying you out in bitcoins! Mining alt-coins and converting to bitcoin is very often orders of magnitude more valuable than mining Bitcoin directly! No registration, no hassles, just point and start getting paid!
"For those that don't understand: When BTC [coin] halves in 36 days, it will be a lot more profitable to mine [Bitcoin Cash] for a lot longer due 2 week difficulty adjustment, causing hashrate to gradually migrate to [Bitcoin Cash] over that 2 week time period."
Bitcoin can adjust itself automatically for mining difficulty, it can also algorithmically reduces coin issuance every four years, yet it cannot increase block size without hard-fork!?
Everything else in Bitcoin is programmed with scale in mind: Number of new coins issued per block, mining difficultly etc. Yet, block sizes are fixed! What if block size was based on some amount off the mining difficulty? If the difficulty increases, so does the block-size which mean Bitcoin is more popular. If the difficulty drops below a certain threshold, block sizes drop because Bitcoin will be assumed to be less popular. That way, block sizes would also be algorithmic like everything else in Bitcoin.
Can someone explain please when less people mine bitcoin this means difficulty decreases? Means coins can be mined much quicker means bitcoin price drops eventually? Sorry if it’s a silly easy question 🤦🏻♂️

''' Also no miners will keep mining the minority not even one day because staying there mean possibly super low coin price with same difficulty. You won't even get much mining reward for weeks. Same time, all miners need to pay electricity and loans for their machines..... Only idiots want to stay......... People here have no idea about business of mining...... Kind of sad. Buy S9 and mine the low profitable core coin if you want..... ''' Context Link Go1dfish undelete link unreddit undelete link Author: KingofKens
Hypothetical question: in the event of a large world disrupting event (war)...
Hypothetically, in the event of a large war, the undersea cables that connect the world with internet could be severed. Satellite internet could be disabled through further wartime acts. We could end up with several discreet, independant internets that are not only separated by great firewalls, but also physically separated from each other. It's my understanding that the block chain would essentially continue in each internet pocket unhindered, but not synchronized. So what happened if after a prolonged period of isolation, let's say 5 years, the networks become reconnected. Would the two block chains "merge" If they merge, how would potentially conflicting transactions be handled? Double spending? Would one block chain fully overwrite the other? Effectively nullifying 5 years worth of transactions? Or would the possible overwrite only affect specific conflicting transactions? Or would they stay as separate discreet chains at that point? Would that mean someone who has keys today would then have keys for multiple sets of bitcoins on multiple block chains with the same keys? (so if I had 1btc today, after the "war" would I then have 1btc [Americas] 1btc [Asia] and 1btc [Europe])
ABC officially forking: All newly mined blocks must contain an output assigning 8% of the newly mined coins to a specified address. While some may prefer that Bitcoin ABC did not implement this improvement, this announcement is not an invitation for debate.
Everyone knows that scarcity of bitcoin is increasing and that the last bitcoin will be mined in 2140. However, bitcoin is going to get much scarcer much sooner than 2140. Here are some rough estimates.
Today ~88% of all bitcoin have been mined.
2022 ~90% of all bitcoin have been mined.
2025 ~95% of all bitcoin have been mined.
2030 ~98% of all bitcoin have been mined.
2034 ~99% of all bitcoin have been mined.
From the year 2034 to 2140 (106 years), the remaining 1% of all bitcoin that will ever exist will be mined. Several decades from now, work will begin on mining the final coin. Mining that final 1 bitcoin will take many decades more. There will come a time when owning a whole bitcoin will be an almost mythical situation that is very rare.
Bitcoin done it right: Having a Hard Cap is a prerequisite to Decentralization as a Cryptocurrency
Any cryptocurrency that doesn't have a max supply isn't decentralized by default. The fact that a cryptocurrency can be prone to inflation or easy manipulation by a central authority in that manner, makes it remove the decentralization label by default. Satoshi Nakamoto did it right. Many other cryptocurrencies are centralized cryptos wearing decentralized crypto's clothing. Bitcoin is one of the few cryptocurrency currently living up to the hype of being decentralized.
The discrepancy between BTC's hashrate and price are extremely suspicious
Assuming fairly efficient ASIC miners, which on average have an efficiency of ~34.5 J/TH: c = Current hashrate = 88,200,000 TH/s e = ASIC Efficiency (average) = 34.5 J/TH a = Average electricity (including industrial and other expenses) = $0.12 USD/kWh b = Current Block Reward = ₿6.25 m = Mining Fee Subsidies = ~₿ 9.5 ∴ price = ~[((c * e)/6,000)(a)] / (b + m) = ~$3864 to produce 1 Bitcoin The actual market price is 138% above the cost of actually producing a Bitcoin. Edit 1: I was an idiot, and forgot that the mining fees were what were collected daily (thanks to u/impleplum, so recalculating, it costs roughly ~$9016 to produce a Bitcoin, making the market value 2% above the cost of production, but Bitcoin Cash still costs $265 to produce, still making it 14% more expensive to mine Bitcoin Cash than the actual market value of it.
https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/22.214.171.124 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
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types
The ability for developers to remove polls and votes
