RE: Seed node? How to?
I found this on GITHUB from the Steem files.....
For a full web node, you need at least 110GB of disk space available. Steemd uses a memory mapped file which currently holds 56GB of data and by default is set to use up to 80GB. The block log of the blockchain itself is a little over 27GB. It's highly recommended to run steemd on a fast disk such as an SSD or by placing the shared memory files in a ramdisk and using the --shared-file-dir=/path command line option to specify where. At least 16GB of memory is required for a full web node. Seed nodes (p2p mode) can run with as little as 4GB of memory with a 24 GB state file. Any CPU with decent single core performance should be sufficient. Steemd is constantly growing. As of August 2017, these numbers were accurate, but you may find you need more disk space to run a full node. We are also constantly working on optimizing Steem's use of disk space.
