Gribble

gribble is a modified Supybot IRC bot, carrying some useful bitcoin-related commands and factoids. The bot's command sequence is ';;', to issue any command just start a line with two semicolons. You can also issue inline commands with two commas.

It is present on #bitcoin-dev (bitcoin information queries), #bitcoin-market (real time streaming quotes from bitcoinmarket.com and mtgox.com), #bitcoin-otc (facilitate over-the-counter trading, with the OTC order book and OTC web of trust). You can also PM commands to gribble and it will PM back.

List of commands

Mining/network/hashrate stats

• bc,blocks - show the current number of blocks in the bitcoin block chain
• bc,calc - given a hash rate in Khps, calculate the expected average time to generate a block, at current difficulty. For example, to see the average time for 1000 Khps, run 'bc,calc 1000'.
• bc,calcd - given a hash rate in Khps, and a difficulty level, calculate the expected average time to generate a block at that difficulty. For example, to see the average time for 1000 Khps at difficulty 1, run 'bc,calc 1000 1'.
• bc,diff - show the current generation difficulty
• bc,diffchange - show estimated percent change in difficulty
• bc,estimate - show the estimate of the next difficulty
• bc,gen - given the hash rate in Khps, calculate expected BTC generation per day and per hour, at current difficulty.
• bc,gend - given the hash rate in Khps, and a difficulty level, calculate expected BTC generation per day and per hour at that difficulty.
• bc,hextarget - show the current difficulty target in hex.
• bc,nexttarget - show the block at which the next difficulty change will take place
• bc,interval - show the average time between blocks, over the past 1000 blocks. If given optional integer argument, use that many blocks for the estimate.
• bc,prob - show the probability of getting at least one block at given Khps, in a given time period. E.g., to see probability of getting a block at 1000 Khps, in 2 years and 1 week, try 'bc,prob 1000 2y 1w'. Time takes input in years, weeks, days, hours, minutes, and seconds.
• bc,stats - show some statistics about the block chain - number of blocks, difficulty, estimated next difficulty target, time to next difficulty
• bc,timetonext - show estimated time to reach the next difficulty target
• bc,totalbc - show total number of bitcoins in existence.

Big kudos goes out to theymos for providing a web interface to real time statistics about the bitcoin block chain.

Markets and exchange rates

• bc,bcm - show the market snapshot from bitcoinmarket.com
• bc,mtgox - show the market snapshot for mtgox.com
• bc,avgprc - show average 24h, 7d, and 30d trading prices of BTC in various currencies.
• bc,24hprc - show average 24h price of BTC in USD.
• bc,btceur - show price of BTC in EUR, based on mtgox last trade price.
• bc,btcgbp - show price of BTC in GBP, based on mtgox last trade price.
• bc,btcrub - show price of BTC in RUB, based on mtgox last trade price.
• bc,fx - show various currency exchange rates
• bc,xau - show price of gold in BTC
• ticker - show pretty-printed mtgox ticker. Takes optional argument of '--bid', '--ask', '--last', '--high', or '--low', to show just that numeric value (useful for command nesting in calculations)
• bids - given a numeric argument, shows how many total btc are being demanded on MtGox at or over the given price. If optional '--under' argument given, looks under the price.
• asks - given a numeric argument, shows how many total btc are being offered on MtGox at or below given price. If optional '--over' argument given, looks over the price.

• bc,slushpool - show the mining hash rate of the slush mining pool, in Khps.
• bc,eligius - show the mining hash rate of the Eligius mining pool, in Khps
• bc,swepool - show the mining hash rate of the Swepool mining pool, in Khps
• bc,btcguild - show the mining hash rate of the Btcguild mining pool, in Khps
• bc,deepbit - show the mining hash rate of the Deepbit mining pool, in Khps

Other

• bc,help - show list of 'bc,' commands - same as 'apropos bc'.
• bc,wiki - fetch a link to a page in this wiki, based on a search string. For example, to see a link to this page, try 'bc,wiki gribble'.
