The difficulty drop coming with the next block (about -15%) is the second biggest, bitcoin has ever seen. The biggest was 2011/10/31 (-18%), after which the price doubled within two months. 15 months later price found itself 20-folded.
The second 300% difficulty increase for Bitcoin Cash is in 30 blocks. What next? Same as before?
The second hash rate exodus is probably upon us. Like the recent article from Mengerian stated, the EDA will be on for a while so, as long as the market price of Bitcoin Cash is, more or less, above 0.14 BTC and bellow 0.35 BTC these swings can occur. What would it take to get Bitcoin Cash over 0.35? Any guesses?
I am very much looking forward to Bitcoin Core's next difficulty adjustment in 1.75 days. My prediction is that 1.) Bitcoin Cash's price will get pumped, 2.) hashrate will flock to it, 3.) Bitcoin Core's block time will go up markedly for 3+ weeks. 4.) Bitcoin Core price will drop.
Let's see how I do on this prediciton over the next week or so.
[Bitcoin Unlimited Strategy] I believe it may be wisest for BU pools to mine the first block larger than 1MB (once we have 75% hashrate) *right after* a difficulty adjustment. This would provide the greatest resistance to a minority chain due to the longest time until the next difficulty adjustment
This would make the fork cleaner by presenting less chance for the minority chain to go anywhere.
Does anyone know what kinda pool reward this is? Thanks so much! (current block reward * no. of mined blocks+tx fees) * hashrate in GH/s * 10^9 / 2^32 * 86,400 / no. of mined blocks before difficulty change * previous difficulty + (no. of mined blocks after difficulty change * next d /r/Bitcoin

''' Difficulty adjusts every 2016 blocks. If the 1MB chain only has 25% of its hashpower, that means blocks come out 1/4 as often, which means it takes 4x as long to reach the next adjustment. So worst case scenario- the 75% fork happens right after an adjustment. At 1/4 rate, it will take two months to reach the next adjustment, during which time the 1MB chain will be at 1/4 transaction capacity (250KB per 10mins). Best case would be if the 75% fork happens about 1.5 weeks into a difficulty period (about 2/3 of the way through). That gives a balance between suffering time until the next difficulty period, and having enough effect that the adjustment is significant. Some smart people have done the math on this, but it still involves at least a month or so of greatly reduced capacity. This of course ignores that the remaining 25% of miners won't keep mining a losing chain out of spite, they will slowly switch to the BU chain. Each time one does, that means more time until another adjustment. Now let's be honest- if 75% of the miners indicate they plan to switch to BU, the Bitcoin ecosystem WILL follow suit. And by the ecosystem I mean users, nodes, payment providers, and even other miners. The economic majority will be happily running BU, and while I'm sure a few die-hards will stay on Core, I doubt that chain would go anywhere.

Scalenet and Testnet4 are online and open for business
Over the years, some people have made use of testnet3 to test out scaling performance, and have spammed testnet3 with 32 MB blocks. This has caused testnet3 to get kinda bloated; the blockchain now takes an hour or so to sync, which slows down development. Other people have wanted to do stress testing, but have specifically wanted to avoid inconveniencing other people by spamming testnet3, and have therefore not done so. This slows down development too. To address this issue, I created two new networks: testnet4 and scalenet. Testnet4 is intended to be a low-volume quick-syncing blockchain which is ideal for testing out new transaction formats or applications. It has a 2 MB default block size limit, and comes with aserti3 parameters that make the difficulty recover quickly to CPU-mineable levels. It should remain easy to sync on a low-end VPS or old laptop. Scalenet is intended to be a high-volume blockchain which is ideal for spamming and stress testing software. It comes with a 256 MB initial default block size limit, and uses aserti3 parameters that make it more suitable for accurately simulating mainnet mining difficulty (though it retains the 20-minute difficulty rule). In order to prevent storage costs from getting unreasonable for a testnet, scalenet will be reset every 6-12 months by invalidating the block at height 10,001 and adding a new checkpoint. Scalenet is intended to be feasible to run on a mid-range desktop computer with some strain. Testnet4 and scalenet are now online and essentially complete. The code for both has been merged into BCHN and Electron Cash. Testnet4 has also been successfully synced to by Knuth, Bitcoin Unlimited, and libbitcoincashj. Block explorers for both are available, thanks to Axel Gembe (who runs the code) and sickpig (who wrote the code): http://tbch4.loping.net:3002/ http://sbch.loping.net:3003/ The testnet4 and scalenet MRs were opened on Aug 19th and Aug 27th, and both were merged on Sep 17th. Scalenet reached height 10,000 on October 3rd. Testnet4 and Scalenet support are present in the master branch of BCHN, and will be included in the next release of BCHN. Some other software (e.g. Electron Cash) already has support in their latest release, but most is still pending. See also: https://bitcoincashresearch.org/t/testnet4-and-scalenet/148/7
[HALVING MEGATHREAD] Block 630000 has been mined. Mining subsidy is now 6.25 BTC per block. The third Bitcoin Halving is now complete!
As of now, 630,000 blocks have been mined on the Bitcoin network, and the block reward has successfully halved for the secondTHIRD time. The previous block reward was 12.5 BTC, and the new block reward is now 6.25 BTC. Since the previous halving at Block 420000, monetary inflation decreased from 4.17%% to 3.57%. Block 630000 signals an immediate 50% reduction to 1.79%. The next halving will occur at Block 840000 in approximately four years. Godspeed, Bitcoin! Here's Block 630000 in all its glory!
Bitcoin's mining difficulty and hashrate surge in tandem. In layman's terms, mining difficulty indicates how hard it is for a computer to produce one block that rewards miners with 6.25 BTC. Bitcoin's mining difficulty adjusts with every 2,016th block. Depending on the speed at which these blocks are mined, this happens roughly once every two ... BitcoinCash mining difficulty determines how difficult it will be to mine the next block and this is why it is referred to as the difficulty of BitcoinCash mining. BitcoinCash difficulty is a measure of how many hashes (statistically) must be generated to find a valid solution to solve the next BitcoinCash block and earn the mining reward. As you can see in the BitcoinCash difficulty chart ... Das Bitcoin-Netzwerk variiert seine Bitcoin Difficulty aller 2016 Blöcke, um einen konstanten Output zu gewährleisten. Wenn die Hash-Rate des Netzwerks hoch ist und die Zeit, die benötigt wird, um einen neuen Block zu entdecken, weniger als 10 Minuten beträgt, dann erhöht das Netzwerk den Schwierigkeitsgrad proportional, um die Blockerkennungszeit zu erhöhen. Wenn die Blockerkennungszeit ... Difficulty is a value used to show how hard is it to find a hash that will be lower than target defined by system.. The Bitcoin network has a global block difficulty. Valid blocks must have a hash below this target. Mining pools also have a pool-specific share difficulty setting a lower limit for shares. Bitcoin’s difficulty target is a 256-bit number that is adjusted every 2016 blocks (~2 weeks) based on the time it took to mine the previous 2016 blocks. The difficulty algorithm attempts to produce a block roughly every ten minutes and is proportionately modified by Bitcoin clients every two weeks to the amount of time higher or lower than it took to mine the previous 2016 blocks.
