Start enforcing block.nVersion=3

lizhi

Now,Our blockchain is version 2. wallet 0.8 and 0.9.3 use version 2. wallet 0.9.5 and 0.11.1 use version 3.

Start enforcing the DERSIG (BIP66) rules, for block.nVersion=3 blocks, when 75% of the network has upgraded.Reject block.nVersion=2 blocks when 95% of the network has upgraded.

If we want to use block version 3, need major pool switch to an up-to-date version of feathercoin core.

My block explorer have suppored block version 3. http://block.ftc-c.com

Thanks for all the hard work, Lizhi.
We need a major pool switch, but the new change over method means it doesn’t have to be done in one 51% change over.
You’ve started warning members now, and we need to look to include it in publicity. Have the new version available so that is the easy option …

Is it possible to run a mixed network of 0.8.7/0.9.3 and 0.9.5?

About 75% of wallets seem be on 0.8.7.X, still.

So that might be the reason why my balance was not showing correctly!

lizhi

@Wellenreiter because wallet 0.8.7 reject version 3 , must upgrade it. a typical user can run 0.9.3/0.9.5 and 0.11.1 ,but pool daemon must run wallet 0.9.5 or 0.11.1 .

lizhi

@mirrax NO , block version 3 not start.

Wellenreiter

So, how can Mirrax work with his 0.9.5 version, and get connected to the BC, if most of wallets are on 0.8.7.x?

I know, that the local data of a 0.8.7 can’t be used, but I thought, that a 0.9.5 client can connect to a 0.8.7.1 or a 0.9.3.0

@Mirrax: can you do a ‘getpeerinfo’ from your 0.9.5 wallet’s console and check for the versions of the connected peers?

Hi, I use 0.9.3 in linux, here is the command line output:

@mirrax : So you have a mixed peer connection, where most peers are 0.8.x and only one peer is on 0.9.5.

This means, that 0.9.5 clients and 0.8.7.x clients talk to each other and exchange information.

@ Lizhi: It seems, that I don’t understand the problem

ghostlander

Just update to BIP66 and keep nVersion=2. v0.8.7 is already DER compatible, though doesn’t enforce it.

Wellenreiter

@ghostlander: thanks for the clarification :D

AmDD

Guys, if we want to push the newer version Id think a good place to start is feathercoin.com. it still showing the 0.8.7.1 version.

wrapper

I have no direct input, as some people are paying money, that’s not the fault of anyone doing the work at the moment. It’s a technical / change over to issue which is already been worked on as part of the forum open source update ‘plan’.

As the technical discussion showed (not a rush) and the limited number of moderators / testers, better to be slow and sure.

As someone limited in how I can help and with experience of similar projects in industry, progress has been remarkable compared to the negative possibilities.

Wellenreiter

@lizhi: I see a peer with version 0.11.1 among others with 0.8.7 and 0.8.7.1.
I’m on 0.9.3.s

This means, that all versions can connect to each other.
Is that a valid prove aready, that the versions are working well with each other?

lizhi

Yes, all versions can connect to each other.
But pool daemon should run 0.11.1 ,it make block 2 or block 3. but 0.8.7 only make block 2 and don’t accept blocks 3.

main.cpp ,line 2249.
/* Don’t accept blocks with bogus nVersion numbers after this point */
if((nHeight >= nForkFour) || (fTestNet && (nHeight >= nTestnetFork))) {
if(nVersion != 2)
return(state.DoS(100, error(“AcceptBlock() : incorrect block version”)));
}
