*(Did you know that already ran a witness node* 😱*[4 years ago](https://ecency.com/witness-category/@forykw/improving-my-skills-as-a-witness)? I was trying to learn as much as I could about this life... was so epic back then* 🤦‍♂️*. Then I got persuaded to go to EOS as a block producer, which didn't go anywhere after 6 months. Still, I learned a lot and I don't regret it because it was a super worth experience!)* # Back with a HIVE witness node This time operating via @atexoras.witness 😎 [![image.png](https://files.peakd.com/file/peakd-hive/forykw/23tkpM8Xzqwdi1zkbeji7ACtSBrXCxacZPPrRVPDCQmh6Qq34QooVjFnkKRpJLLyYUMd3.png)](https://peakd.com/@atexoras.witness) And what an amazing way to start 2022, right?... Still, lots to go, since it's not meant (for now) to be a public node for RPCs or as a seed node, but it does make you feel kind of free and empowered on being part of this community. ##### I HAVE turned ON the following plugins... ``` ~$ cat localhive/datadir/config.ini |grep plugin |grep -v '#' plugin = webserver p2p json_rpc plugin = account_by_key_api condenser_api plugin = witness plugin = rc plugin = block_api network_broadcast_api rc_api plugin = state_snapshot ``` I will be playing with a couple of these in the near future and make adjustments as I go. Lot's to learn as there are new things I didn't follow the development. You can vote for it **[HERE](https://vote.hive.uno/@atexoras.witness)** if you wish. The link uses a great [tool](https://peakd.com/hive-169321/@cadawg/new-tool-for-hive-witness-voting-page-with-hivesigner-keychain-support) developed by @cadawag that makes it super simple to vote for witnesses, no matter where you are. Remember to support its witness too if you like what he has done. ![image.png](https://files.peakd.com/file/peakd-hive/forykw/23tbKK8aAUciVtW6nEnJexZLyF7cLbBEpXLS3ypRVvSKEoaVWHX6yZn8s2N8dCKtGohjF.png) No blocks signed so, that's why there is no version, but I am running 1.25.0 ``` ~$ curl -s --data '{"jsonrpc":"2.0", "method":"condenser_api.get_hardfork_version", "params":[], "id":1}' localhost:8090 {"jsonrpc":"2.0","result":"1.25.0","id":1} ``` And enough RC mana, although it's something I will start monitoring in case it falls below 50%... ``` ~$ curl -s --data '{"jsonrpc":"2.0", "method":"rc_api.find_rc_accounts", "params":{"accounts":["atexoras.witness"]}, "id":1}' localhost:8090 {"jsonrpc":"2.0","result":{"rc_accounts":[{"account":"atexoras.witness","rc_manabar":{"current_mana":"932981261795","last_update_time":1640917200},"max_rc_creation_adjustment":{"amount":"5709043939","precision":6,"nai":"@@000000037"},"max_rc":"933121590307"}]},"id":1} ``` ##### What's this helping the community with? For now, let us say that we have **another copy of the HIVE DB in New Zealand, in sync, further promoting decentralization and the security of this blockchain.** The main objective, for the time being, is to help me (no seed/RPC available yet, sorry 😭) with my other witnesses' initiatives, on Hive-Engine and DLUX. Still, I need to go through a couple more "works" into it but saying that I managed to get this node running in 4 days, including downloading (with `axel`, tks @apshamilton) the entire chain from @gtg (link [here](https://gtg.openhive.network/get/blockchain/)), prepare a VM, replay the entire thing, and make some local tests... I would say, it felt pretty damn great. Still not perfect but I guess it's what I could do with what I have. **I intend to help others that need to go through the process, so, if are attempting to build a local node like me (for now), reach me out anywhere. Will help with what I can/know or direct you to others that know more than me.** Next year I need to buy a new CPU (because now things are getting exciting). All is going to be supported by my own fricking limited resources! **I am here because I like it, want to contribute to and be a part of it...** Although it costs money to run these things, be rest assured. # Witness status The code is way more efficient today than 4 years ago 😎... the community team contributing to further developing this really did a Mega Hyper job! Well done everyone. ![image.png](https://files.peakd.com/file/peakd-hive/forykw/23tRxWb2MSWRKsCAuMuoPEZER9igiXrmr8jCNxdz52NwPufUTYvA7oxvaZNnDeFhEMXYA.png) - 8GB of RAM (that could even go to 4 or 2GB) - for witnesses, RPCs, and non-history nodes it's enough (wait for it) if you use the shared memory file in NVMe like me. Just to give you a hint, active memory is less than 1GB... so most of it is for caching situations. - 6 vCPUs (based on Zen2 AMD cores) - overkill... 4 is more than enough! - I might reduce... - shared memory file... (currently 20GB) on an NVMe (max 50-60k IOs observed during replay), could go more... but needs more frequency because the replay process is single-threaded. The common alternative to this is to create a ramfs and host the shared memory file there... memory is more efficient on IOops than NVMe, hence faster! - block_log in local ordinary rotary disks using LVM with a 3-stripe array (it needs some IO at the beginning of the index building, but after it, its requirements are as low as any disk can handle, as far as I could see). # Experience... The replay took almost 3 days... but I moved the block_log into and NVMe for the index rebuild, then back to the rotary disk. That single-threaded(?) process that does most of the replay takes most of the time. Overall, the experience of re-learning things was not difficult. I had already some experience, so for others that don't it might be harder, but if you have some help is not a big deal. This time of the year is also not the best time to build things... LOL, I can't blame anyone. But doco could improve, there are lots of old stuff and copy-paste jeopardy that for the new user will be dust in the eyes. Maybe this is something I can help with (will be evaluating that), but otherwise, let me know. # Documentation and Resources used During the setup, I have used mostly ecency searches, some witnesses guides, and HIVE documentation and source code. Here are some of the useful links I consulted with: - https://developers.hive.io/ (Official Documentation) - https://gitlab.syncad.com/hive/hive (Hive source code) - [How to run a witness node on the hf25 testnet](https://peakd.com/guide/@howo/how-to-run-a-witness-node-on-the-hf25-testnet) - [How To Set Up A Hive Engine Witness- Step By Step Guide](https://peakd.com/engine/@rishi556/how-to-set-up-a-hive-engine-witness-step-by-step-guide) - [How to set up a Hive Witness or Seed node (non-MIRA) / Upgrade from Steem-Docker to Hive-Docker](https://peakd.com/hive-139531/@someguy123/how-to-set-up-a-hive-witness-or-seed-node-non-mira-upgrade-from-steem-docker-to-hive-docker) - [New Tool For Hive: Witness Voting Page With HiveSigner/Keychain Support](https://peakd.com/hive-169321/@cadawg/new-tool-for-hive-witness-voting-page-with-hivesigner-keychain-support) - [How To Setup Hive Witness Pricefeed Using Hivefeed-JS](https://peakd.com/witness/@rishi556/how-to-setup-hive-witness-pricefeed-using-hivefeed-js) # Possible TodoS! For only 4 days of work, I am pretty happy. But there is some stuff I need to complete still... - Add Jussi reverse-proxy to the node. - Add failtoban and test some profiles (not sure if there are some already there) - Allow specific witnesses nodes "to talk" seed/RPC to my node (via IP whitelist) - if you wish to be whitelisted, let me know where you are communicating from. - Explore certificate-based options for the above situation... - Others I might be missing out on... # Upgrades on the horizon... more like wishes! - CPU... (500-2000 NZD) I NEED LOTS MORE! I wish I had only one of my work threadrippers... 😐 - Grow to a 128GB RAM (1200-1400 NZD) hypervisor and move the shared memory file in ramfs - New firewall/router (1000-3000 NZD) - Upgrade ISP connection (moderate expensive but might become viable with other projects) # 2023 Scope "dream" wishes If this can even be a possible scenario, this would be the objective! This is not yet a plan, just a dream wish... let's see what will change when we get there! #### Hardware: - Dual 10Gbps Firewalls (with HA) - 2x 6-10Gbps ISP links - 4x Hypervisors (32 core, 64-threads each and 256-512GB RAM) - 2x GPUs/accelerators - 10Gbps core switch(es) (1 or 2) - 6-12Gbps SAS FC Storage (shared across the 4 hypervisors) - 8Gbps or more FC HBA's - x2-x4 NVMes, some SSDs, and some HDDs... - Some bigger UPSs for minimal support - Find a place at home to put all this without getting divorced 🤣 #### Brainstorming services: - 2x HIVE witness/RPC nodes with HA availability - 1x HIVE seed node - 2x HIVE history nodes - 2x Hive-Engine witness nodes - 1x Hive-Engine snapshot node - 2x DELUX nodes - 1x 3Speak node (encoding + IPFS) - 1x Monitoring page for the services state (public) I don't even know how much this would cost right now... but the point is to say that if in possession of this hardware, I could make it happen, just by myself. Would just need a bit of help on the last item (webpages are not my style) 😅 # Wish you the best for 2022! Stay safe, if possible near your loved ones, and enjoy the last day of the year the best you can. I am going in first then most of you (in a few hours)... so, see you on the other side.
