Ok, validators list and explorer links were added. Thanks for the suggestion.

The instance specification: 2vCPU with 8gb RAM and 200 GB storage, to run 6 nodes, looks bellow the recommended specs per node: 2 cores, 4 GB RAM and 200 GB HDD. I am curious how it will perform. Keep us updated 🙂 The recommended approach is for each node to add 2 cores, 4 GB RAM and 200 GB. But only by testing we can know for sure and this is one of the reasons we are doing BoN.

I will use for BoN a t3.2xlarge AWS machine (8 vCPU and 32 GiB RAM) to run 6 nodes. The price for this on-demand instance is around 240$ per month and it does not include traffic ( around $0.09 per GB). It looks kind of expensive right now from what I heard from others but with a reserved instance the price could go down by around 80%. Next for me would be to test Google Cloud and Microsoft Azure.

If you are using a hosting/cloud provider which one(s) are you using? What specs your machines have and what are the estimated costs per month?

Week #40 | Monday, September 30 – Sunday, October 6, 2019 1. Preparations for the Battle of Nodes (improvements, bugfixes, benchmarks, tests) 2. Initial implementation of a System VM and smart contract for validator staking, that will allow nodes to join the network real-time, through a fast protocol built-in mechanism 3. VS Code extensions can handle WASM smart contracts written in C and Rust. Work in progress to enable debugging of such code in the IDE 4. First flood attack on our testnet v1.0.19 made us tweak the libp2p's parameters and craft additional anti-flooding capabilities 5. Fixed the arm64 build so we can now run validators on raspberry pi4 6. Refactoring of shard processor in order to remove duplicate code and group all arguments in a single structure 7. Snapshot of the trie for saving the current state of the trie in a separate database. 8. Compaction of miniblocks to allow us to add more transactions in a block and decrease the data that needs to be propagated to metachain. Throttled mini blocks creation to a defined maximum value, to avoid bottlenecks with blocks with a too higher number of miniblocks 9. Added a local cache of meta blocks, used for processing current shard block, to avoid situation when a full pool of meta blocks (happening especially when a node is bootstrapping), would generate situation when needed meta blocks are in fact evicted from pool 10. Validator's uptime statistic improvements for the Battle of Nodes 11. Added more data in Elastic Search related to consensus group, will be visible in the testnet explorer 12. Economics rewards metrics for termui. Soon an estimation of how many ERDs you can earn 13. Fixed bug that caused in some situations the block to be rejected due to missing reward transactions 14. Fixed a bug after merging with the economics part which didn't allow the node to start 15. Further bugfixes and improvements

Here is one with Battle of Nodes. Maybe someone can make some with Elrond?

Good to have you guys around! Lets make Elrond great!

Welcome to our community @zillabytes.

Hi Alex and welcome. See you are around! 👋

Welcome! Looking forward to seeing what you are up to!

Hi Randy and welcome! Indeed at some point in the future an intro topic per person might be too much. But for now, still being at the very beginning I feel like we can try to know each other better. 🤨

You can start by reading more info about vector attacks. Here is a short list from you to start with, but feel free to search for more info: https://blogs.arubanetworks.com/solutions/10-blockchain-and-new-age-security-attacks-you-should-know/ https://www.apriorit.com/dev-blog/578-blockchain-attack-vectors https://gsec.hitb.org/materials/sg2018/D2 COMMSEC - Blockchain and Smart Contract Attack Vectors - Jorden Seet.pdf https://ieeexplore.ieee.org/abstract/document/7958588

Hi guys. I am Lucian. I am a serial technology entrepreneur and angel investor, with more than 15 years experience in Internet and tech related businesses. I took the first step towards entrepreneurship in 2001, when, as a 21 years old student, launched the first website that later became known as Soft32.com. In 2002, I decided to drop The Bucharest University of Economic Studies where I was specializing in Finance, Insurance, Banking and Stock Exchange in order to focus on building and expanding the Soft32 platform that, at its peak, listed more than 150 000 apps and was visited by more than 10M users each month. Soft32 was acknowledged in 2014 as one of the fastest growing tech startups in Europe and EMEA. I was involved in several other tech startups activating in mobile payments, gaming, travel or mobile advertising. As an angel investor I invested in several companies: Smartbill - the most used Romanian invoicing and accounting SaaS platform; TypingDNA (Techstars NYC'18 Company) offering typing biometrics and 2FA solutions for securing devices and web applications; Homefresh, the pioneer meal kit delivery service. In the last 2 years I focused on blockchain projects as well. At Elrond I am more focused on the operational and financial side, but I am also managing a user-focused project, soon to be launched.
