/ mining is GPU intensive (not worth trying on CPU as you will not get meaningful financial rewards for it) but does not have much more bandwidth requirements than a full node.If you consider mining: keep in mind that Ethereum will change to proof of stake and mining will not be requierd anymore at some point (nobody knows exactly when, but it might be in half a year or a year or so), so your return-of-investment should not be longer than that.up vote 3 down vote Tl;tr Pool mining doesn't require a full node.Mining is a computational heavy processes and its highly taxating on the GPU.Solo mining requires a full node, but you need to own a large hashpower to see a steady income stream from it.As of today, you need at least 5 modern GPUs to mine an ether a day.Longer: If you join a mining pool, then mining doesn't necessarily requires a full node.The mining pool runs a full node, or multiple for redundancy, and each time it receives a block it sends its header as a work package to its miners.

This system is not trust-less: miners within a pool have to trust the pool to provide a verified, authentic block.But there is a mutualistic economic relationship between pool and miners: if a pool doesn't provide authentic blocks, its miners will lose the reward and they will likely leave the pool, which will then lose the fees miners pay to stay within the pool.bitcoin aliens hackThis is true as long as a pool has substantially less than 51% of the overall network hashrate.bitcoin hash vs litecoin hashSolo mining does require a full node for now, since it's on top the last block that you start mining: i.e, the hash of the last block header is an input of the mining process.dogecoin listPotentially, when light client support will come around, you will be able to mine on a light client.bitcoin block difficulty

If you need to run JSON-RPC, you'll also need TCP port 8545.Note that JSON-RPC port should not be opened to the outside world, because from there you can do admin operations.All client's ports can be customized from the default.If you want geth/eth to find UPnP, you'll also want that enabled on your router.bitcoin became richThat's just so it can listen on a port, not necessary if you've already manually opened/routed them.About the wiki page you linked, it reports actually just an example: If the TCP and UDP (discovery) ports differ, the UDP port is specified as query parameter discport.In the following example, the node URL describes a node with IP address 10.3.58.6, TCP listening port 30303 and UDP discovery port 30301.I think this misunderstanding is spreading also because of the behavior of the bootnode util.In fact, it uses 30301 as default UDP discovery port.Browse other questions tagged network firewalls port-numbers or ask your own question.
