I’m wondering why doesn’t Bitcoin use something like Redis. Redis store the information in memory, but when you restart your daemon, the data stays there. Why is it better the way Bitcoin handle this issue? ThanksRead more

I see different reports of transactions in mempool. From 35k (statoshi.info) over 170k (blockchain.info) to 215k (bitaps.com). All pages claim to report in realtime. Why is that? The difference is so big that it can not be caused by sync delays..Read more

I can see a lot of questions posted on Reddit similar to “My transaction is not confirmed for X days. What do I do?”. The most common answer is “Transactions are cleared from mempool after 2 weeks”. Can anybody please explain how it is technically possible? Say I broadcast a raw transaction through bitcoin-cli. ARead more

Three bitcore nodes (version of bitcoind is quite old – 0.12.1) are deployed to the servers on different cloud platforms. All instances have the same bitcoin.conf files (except of rpcallowip, rpcuser and rpcpassword): server=1 whitelist=127.0.0.1 txindex=1 addressindex=1 timestampindex=1 spentindex=1 zmqpubrawtx=tcp://127.0.0.1:28332 zmqpubhashblock=tcp://127.0.0.1:28332 rpcthreads=8 rpcworkqueue=32 rpcservertimeout=60 rpcallowip=127.0.0.1 rpcuser=… rpcpassword=… uacomment=bitcore The problem is all of them haveRead more

I understand that each node is different and will have a different mempool (and size). But in looking at https://tradeblock.com/bitcoin/ it is showing a mempool size of around 20MB (http://bitcointicker.co/networkstats/ shows similar mempool size of 20MB). But https://blockchain.info/charts/mempool-size is showing a mempool of 103MB (https://jochen-hoenicke.de/queue/#24h showing similar 100+ MB size). Neither site explains how theyRead more

I want to get CPFP information out of full node – that is, ancestorsize and ancestorfees – in order to calculate the necessary fee for either CPFP, or RBF if possible. Can I get this information through RPC without requesting the full mempool dump? I need this to build tools for CPFP/RBF, that are connectingRead more
