We're excited to announce Blockstream Satellite 2.0. This major update includes a new transmission protocol, more bandwidth, a larger coverage area, & the much requested ability to sync a Bitcoin node from the genesis block up to the latest block!
I've had my first bitcoin core full node running for 24hrs as of this morning and it's sent 25gb of data in that time, is that about right, higher or lower than normal? Edit: what do I need to put in the config file to limit the upload data as that's way too much for me to keep it running 24/7, I'll get a letter from my isp warning about usage again. Despite being on an unlimited package I usually get a letter warning about fair use when I go over 750gb a month.
Hacking, Distributed/State of the Bitcoin Network: "In other words, the provisioned bandwidth of a typical full node is now 1.7X of what it was in 2016. The network overall is 70% faster compared to last year."
How does Bitcoin handle consensus checks with other nodes without using tons of bandwidth?
Let's say you and I and a million other people run a node. Each of our blockchains are hundreds of gigabytes. How do we communicate them to other nodes to determine who has the longest chain? Do we start with the current block and go backwards until we find a number of similar blocks that we both agree on? With the assumption that if I've already downloaded a blockchain from someone and validated every transaction that I can be mathematically sure that once our blockchains are matching I don't need to validate the rest? What happens if a bad actor has a blockchain that is dramatically different from the one I have and it is longer? Do I need to then download the entire blockchain from them (hundreds of gigs) in order to validate it? How does Bitcoin prevent this from happening? Since the mining/wallet software would have rules for how many leading 0's need to be in the hash, and since we can inexpensively (compared to finding the hash in the first place) validate the hash progression, can we just work backwards and the moment there isn't a valid block we just cut the connection? I guess we can't just cut the first half of the blockchain and stick it at the end to force validation of half the massive blockchain before an invalid block appears and we cut connection since the proof of work leading 0s have probably changed over time...but if they hadn't wouldn't this be a valid way to cause nodes to spend at least part of the hundreds of gigs downloading and validating from bad actors? I have no idea how this is actually implemented. I would appreciate it if anyone could correct me.
Most Bitcoin nodes also act as a Bitcoin client, which allows transactions to be sent to the network. This means a node acts as your personal interface with the Bitcoin network as a whole. Running a node ensures that your Bitcoin transactions are verified and sent to whoever you’re transacting with. This puts the power to send uncensorable ... Bandwidth overheads for finding transactions to relay become independent of the number of connections, possibly increasing the number of connections supported by each node. The beauty of the solution is that it does not require any changes to Bitcoin’s network consensus rules. Node bandwidth reductions. The ability of nodes to connect to more peers. The bandwidth reduction using MiniSketch is evident and can be used for more efficient block propagation in low-bandwidth satellite links. The diminished bandwidth burden per node would also enable nodes to connect with more peers than usual — such as 16 rather than 8. Other advantages and applications of MiniSketch ... If your goal is just to get a stable Bitcoin node running, and not to contribute to the network, you can add listen=0 to your bitcoin.conf file. This generally (though not always) keeps your upload bandwidth in check. If you want to contribute to the Bitcoin network without using up too much of your own bandwidth, however, there are ways of limiting your upload speed for Bitcoin Core (Bitcoin ... Full Node¶. The first and most secure model is the one followed by Bitcoin Core, also known as a “thick” or “full chain” client. This security model assures the validity of the block chain by downloading and validating blocks from the genesis block all the way to the most recently discovered block.
