QDA Miner is an easy-to-use qualitative data analysis software for organizing, coding, annotating, retrieving, and analyzing collections of documents and images. QDA Miner qualitative data analysis tool may be used to analyze interview or focus group transcripts, legal documents, journal articles, speeches, even entire books, as well as. Miner training or the experienced miner training depends on whether the miner is an 'experienced miner' under Section. Extraction and Production No work time minimum is associated with this provision. Independent contractors who perform extraction and production work must receive the appropriate comprehensive training.
This guide covers the Lotus Miner configuration files, detailing the meaning of the options contained in them.
The Lotus Miner configutation is created after the initialization step during setup and placed in
~/.lotusminer/config.toml
or $LOTUS_MINER_PATH/config.toml
when defined.The default configuration has all the items commented, so in order to customize one of the items the leading
#
need to be removed.TIP
For any configuration changes to take effect, the miner must be restarted.

# API section
The API section controls the settings of the miner API:
Reference Mining
As you see, the listen address is bound to the local loopback interface by default. If you need to open access to the miner API to other machines, you will need to set this to the IP address of the network interface you want to use, or to
0.0.0.0
(which means 'all interfaces'). Note that API access is protected by JWT tokens, but it should not be open to the internet.Configure
RemoteListenAddress
to the value that a different node would have to use to reach this API. Usually it is the miner's IP address and API port, but depending on your setup (proxies, public IPs etc.), it might be a different IP.# Libp2p section
This section configures the miner's embedded Libp2p node. As noted in the setup instructions, it is very important to adjust this section with the miner's public IP and a fixed port:
The connection manager will start to prune the existing connections if the number of established crosses the value set for
ConnMgrHigh
until it hits the value set for ConnMgrLow
. Connections younger than ConnMgrGrace
will be kept.# Pubsub section
This section controls some Pubsub settings. Pubsub is used to distribute messages in the network:
# Dealmaking section
This section controls parameters for making storage and retrieval deals:
ExpectedSealDuration
is an estimate of how long sealing will take, and is used to reject deals whose start epoch might be earlier than the expected completion of sealing. It can be estimated by benchmarking or by pledging a sector.WARNING Web scraping open source tools.
The final value of
ExpectedSealDuration
should equal (TIME_TO_SEAL_A_SECTOR + WaitDealsDelay) * 1.5
. This equation ensures that the miner does not commit to having the sector sealed too soon. Unfinished memoir priyanka chopra pdf.# Publishing several deals in one message
The
When a deal is ready to be published, lotus will wait up to
for other deals to be ready before sending the
PublishStorageDeals
message can publish many deals in a single message.When a deal is ready to be published, lotus will wait up to
PublishMsgPeriod
for other deals to be ready before sending the
PublishStorageDeals
message.However once
MaxDealsPerPublishMsg
are ready, lotus will immediately publish all the deals.For example if
PublishMsgPeriod
is 1 hour:- At 1:00pm Deal 1 is ready to publish.
Lotus will wait until 2:00pm for other deals to be ready before sendingPublishStorageDeals
- At 1:30pm Deal 2 is ready to publish
- At 1:45pm Deal 3 is ready to publish
- At 2:00pm lotus publishes Deals 1, 2 and 3 in a single
PublishStorageDeals
message.
If
lotus would immediately publish Deals 1 & 2 in a single
Deal 3 would be published in a subsequent
MaxDealsPerPublishMsg
is 2, then in the above example when deal 2 is ready to be published at 1:30,lotus would immediately publish Deals 1 & 2 in a single
PublishStorageDeals
message.Deal 3 would be published in a subsequent
PublishStorageDeals
message.Note: If any of the deal in the
PublishStorageDeals
fails validation upon executation, i.e: start epoch has passed, all deals will fail to be published.# Using filters for fine-grained storage and retrieval deal acceptance
Your use-case might demand very precise and dynamic control over a combination of deal parameters.
Lotus provides two IPC hooks allowing you to name a command to execute for every deal before the miner accepts it:
Filter
for storage deals.RetrievalFilter
for retrieval deals.
The executed command receives a JSON representation of the deal parameters on standard input, and upon completion its exit code is interpreted as:
0
: success, proceed with the deal.non-0
: failure, reject the deal.
The most trivial filter rejecting any retrieval deal would be something like:
RetrievalFilter = '/bin/false'
. /bin/false
is binary that immediately exits with a code of 1
.This Perl script(opens new window) lets the miner deny specific clients and only accept deals that are set to start relatively soon.

by Murmuration Labs:# Sealing section
This section controls some of the behaviour around sector sealing:
# Storage section
The storage sector controls whether the miner can perform certain sealing actions. Depending on the setup and the use of additional seal workers, you may want to modify some of the options.
# Fees section
The fees section allows to set limits to the gas consumption for the different messages that are submitted to the chain by the miner:
Depending on the network congestion the base fee for a transaction may grow or decrease. Your gas limits will have to be at any case larger than the base fee for the messages to be included. A very large max fee can however result in the quick burning of funds when the base fees are very high, as the miner automatically submits messages during normal operation, so be careful about this. It is also necessary to have more funds available then any max fee set, even if the actual fee will be far less then the max fee set. *MaxWindowPostGasFee is currently reduced, but the setting used should remain fairly high, eg. 2FIL.
# Addresses section
The addresses section allows users to specify additional addresses to send messages from. This helps mitigate head-of-line blocking for important messages when network fees are high. For more details see the Miner addresses section.
