Devs: with only 64 validator nodes, would an attack by first spamming the network with tx's and then dDOSing a handful of validators not lead to the remaining validators getting overwhelmed and crash? It seems a rather vulnerable setup, esp considering a validator node needs 8GB RAM to handle 5K tx. Even on an expensive VPS, there would not be a lot of room for additional load.

Or am I wrong?

This is definitely a possibility regardless if we are using 64 or 100 validators. Validators need to have sufficient bandwidth, RAM and processing power to handle large amount of transactions and the recent and ongoing RC tests are going to expose these vulnerabilities. With these vulnerabilities exposed our Devs can work out a solution to prevent these problems from happening before we go on mainnet.

I do software, so I know how usually strangers coming in and proposing "simple solutions" is a reason to face-palm, so forgive me if I am talking nonsense...

In such a situation, I would either have a couple of "dark validator nodes" that light up once others go down (latencies and throughput should be measurable) or have a large pool of nodes and have them switch on and off in a random fashion so the mean is 64 active validators.

Both make it harder keeping a sustained dDOS going. In your current setup, I'd be afraid of knock-on effects of a percentage of the validators getting taken out.

Interesting ideas. Since we're talking nonsense I was thinking once all the validators are mostly pools, will there be a way to incentive people to check on their votes? I'm thinking people will vote and forget, or die, etc.. so you'd get votes parked for a very long time or forever.. leading to reduced voter participation. (Over really long periods burned votes could come from unintentionally burned addresses, and accumulate for certain pool validators) Do votes eventually expire?

Eventually, there will be only private communication between the validators at the core (validator can distinguish if a connection is from a validator or not). Each validator only allows connections from a small number of trusted backbone nodes, which are open to any regular nodes. This network architecture is scalable and robust to ddos attack.

It takes time and money for people to build this infrastructure, but we will get there as the eco system evolves.


P.S. The current kernel implementation can already handle transaction flooding. The only reason that the network got stuck last time is because some validator nodes are not qualified. We're considering slashing mechanism

do we earn anything by voting?

You can earn coins by voting for pools.

When the second airdrop will begin？after the test of 5000txs, the network is now stable, which is a major test, and the number of concurrent Numbers is the bottleneck of the blockchain.

Please don't use blockchain downloaded from archive. It's extremely unsecure because it can be already modified.

man trust it's not modified.... i don't have the know/how for modify a blockchain...
sometimes my computer freeze and i need to download intere blockchain so i think this thing it could happen to someone else and i make this zip database

What an interesting project, I have been reading about it now and feel it will be something interesting

[starblocks]

I missed this but its great that its a give away for the community

Will bookmark it for the second phase

When is it likely to become tradable on exchanges?

the community is not very strong ,hope will have normal signature campaign to earn support sem coin.

There is no exchange yet as we are in the stress test mode of the wallet and no final build has been release yet but if you want to trade your semux here is thread to the OTC trading and always use escrow.

nice job buddy,

in bitcoin we had such free services to download daily snapshots, but for altcoins still no one is supporting that yet
hope to get them done at least by dev teams so new users or newly installed wallets wont take years to sync

publish discussion board just once? got my wallet synchronizing at this time looking to get my very first cash

congrats on that and welcome to 1 of the most success altcoin worlds  around

Is the rc2 test terminated again?I see that the wallet block can't be updated.
