Artefact2: Eligius also accepts donations.

Reward types & explanation:
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 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. This method is vulnerable to ''pool swapping'' cheat, where a worker would swap to another pool, if this one didn't find a block quickly. Then he would have extra profit on fast rounds, and normal profit on long rounds (because he would be mining on another pool by then). To mitigate this problem pools must introduce extra fees, and hide statistics, so that it is unknown when a block is found.
* '''Score''' - Score based system, the most advanced one. It is a proportional reward, but it is impossible to cheat as described above. 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 more than earlier shares, thus swapping away to another pool on longer rounds makes the cheater's score to quickly diminish. Rewards are calculated proportionally to scores (and not to shares). Statistics can be shown "live" without fear. The score based method is perfect for 24/7 miners. (at slush's pool C=300 seconds, and every hour scores are normalized)

Artefact2:

'''Eligius''', also sometimes referred to as Éloi or "Luke-Jr's pool", is a [[Pooled mining|mining pool]].

To use it, a miner merely needs to be directed to pool.bitcoin.dashjr.org on port 8337, with the username set to a valid bitcoin address (which receives the payout). '''No registration is needed.'''

Donation address: 1RNUbHZwo2PmrEQiuX5ascLEXmtcFpooL

Basic concepts:
* Pool keeps all transaction fees to itself, plus 0.00000001 BTC per second since last-found block (currently this works out to about 0.0003%, and gets smaller with more miners in the pool).
* Remaining reward is divided equally among ALL shares contributed since its last-found block.
* When a block is found, the miner is paid for that block immediately as a Generated transaction, but only if his total balance is over 1 BTC (to help the recipient avoid transaction fees).
* If a block is orphaned, its shares become part of the next block's reward distribution.
* No registration. Just send username with the address you want payouts to (password can be anything).
* Will only include transactions in its blocks if the sender pays a fee of at least 0.00004096 BTC per 512 bytes.

Eligius was announced on April 27, 2011<ref>[https://www.bitcoin.org/smf/index.php?topic=6648.0 Please test: New Experimental Pool]</ref>. At the time the service was operated without a name, paying out even tiny coins immediately.

==To use==
Please be sure to pass a valid address as your username. Incorrect usernames are silently ignored and earnings are kept by the pool.

* '''poclbm''': poclbm.exe -d1 --host=pool.bitcoin.dashjr.org --port=8337 --user='''YourAddress''' --pass=x
* '''phoenix''': phoenix.exe -u http://'''YourAddress''':x@pool.bitcoin.dashjr.org:8337 -k poclbm DEVICE=0 VECTORS BFI_INT FASTLOOP AGGRESSION=6

* '''ufasoft''': bitcoin-miner.exe -a 5 -o http://pool.bitcoin.dashjr.org:8337 -u '''YourAddress''' -p x

==Troubleshooting==
=== warning: job finished, miner is idle ===
Try using port 80 instead of 8337, and/or setting your router to prioritize port 8337.
