'''Jonny Bravo's Mining Emporium''', also known as '''Bravo Mining''', is a [[Pooled mining|mining pool]] that allows mining bitcoins (BTC). Quietly launched in November, 2015, the pool found its first block on December 15, 2015.<ref>[https://www.blocktrail.com/BTC/block/000000000000000003c3a6ee87941ea88ab99490e7774ae25dc48deb9aa2bf72 First Block]</ref> In addition to mining income, miners on the pool are also provided periodic promotions, which helps to boost earnings. To date, the pool has given away over 11.5 BTC in promotions to its miners from contests and block finding bonuses.

The [[coinbase]] signature for this pool is: "/bravo-mining/"<ref>[https://www.blocktrail.com/BTC/tx/9859c5fbe83b64962e99179ca1b72c72a6d6b594c0b97facbfd9f4bc02db915a#tx_messages Example of decoded coinbase]</ref>

Reward types & explanation:
* '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]
* '''DGM''' - Double Geometric Method. A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]
* '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]
* '''POT''' - Pay On Target. A high variance PPS variant that pays on the difficulty of work returned to pool rather than the difficulty of work served by pool [https://bitcointalk.org/index.php?topic=131376.0]
* '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.
* '''PPLNSG''' - Pay Per Last N Groups (or shifts). Similar to PPLNS, but shares are grouped into "shifts" which are paid as a whole.
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amoutripnt of BC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 12.5 BTC divided by <current difficulty>. It is risky for pool operators, hence the fee is highest.
* '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
* '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]
* '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)
* '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]
* '''FPPS''' - Full Pay Per Share. Similar to PPS，but not only divide regular block reward (12.5 BTC for now) but also the transaction fee. Calculate a standard transaction fee within a certain period and distribute it to miners according to their hash power contributions in the pool. It will increase the miners' earnings by 7%-11%.

== SPV Mining / Old Bitcoin Core ==

The following pools are known or strongly suspected to be mining on top of blocks before fully validating them with Bitcoin Core 0.9.5 or later. Miners doing this have already lost over $50,000 USD during the 4 July 2015 fork and have created a situation where small numbers of confirmations are much less useful than they normally are.

* BTC Nuggets
* [https://www.f2pool.com/ F2Pool]<ref name="spv_despite_incident">[https://bitcointalk.org/index.php?topic=700411.msg11790734#msg11790734 Intention to continue SPV mining], Wang Chun, 4 July 2015</ref>
* AntPool<ref name="spv_despite_incident" />

The following pools are believed to be currently fully validating blocks with Bitcoin Core 0.9.5 or later (0.10.2 or later recommended due to DoS vulnerabilities):

* [[BitMinter]]
* BTC China (described as SPV mining<ref name="spv_despite_incident" />, but they're performing effective valiation)
* [[BTC Public Mining Pool]]
* [[CKPool]]
* [[Eligius]]
* [[P2Pool]]
* [[Bitcoin Pooled Mining|Slush Pool]]
* [[BCMonster.com]]
* [[Jonny Bravo's Mining Emporium]]

<ref name="hashrate2">Note that pool hashrate is largely irrelevant but can be seen as a popularity measurement. It is a theoretical security issue if one pool gains above 50% of the total computational power of the network, thus consider joining a pool based on other metrics. The pool's total hash rate is very dynamic on most pools. Over time, as the network grows, so does most pool's hash rates. The displayed values are the pool's relative sizes based on the network: Small: less than 2%, Medium: 2%-10% Large: greater than 10% of the network.</ref>
