Test Net for Advanced Users

[Fox]

All nodes are now up to date with master. 

FYI - I did encounter unclean database shutdown detected >> resync blockchain on about 1/3 of the nodes.  All were previously the prior day's build.

Special thanks to the five (5) community members taking part in the fund matching offer to support Clayop's efforts with spamming the network from a global VPS entourage.  These individuals combined to contribute 9500 BTS.  I kicked in an extra 500 BTS extra, making it a 5-digit match.

Again, thanks to the community and Clayop. 

Best,
Fox

[bytemaster]

New code has been checked in to improve propagation of transactions during flooding by requesting multiple transactions at once.

All nodes will have to upgrade to get the full benefit so please post once you have upgraded.  Once enough nodes have updated then we can try the flooding tests again.

https://github.com/cryptonomex/graphene/commit/74bbde785b3d9c492007aced389df597b16cf124

[theoretical]

You may have recently noticed a 20% decrease in fees, and witness pay being lowered to 5 BTS per block.  This is our testing of the parameter change functionality described at https://bitshares.org/technology/delegated-proof-of-stake-consensus/#parameter-changes-by-elected-delegates

Unfortunately the witness pay change was inadvertently reverted due to certain technicalities of how proposals work, but I re-applied it in another proposal which will take effect fairly soon.  So here are the new parameters:

Code: [Select]

propose_parameter_change init2 "2015-09-29T19:45:00" { "maintenance_skip_slots": 4, "maintenance_interval" : 1800, "maximum_transaction_size": 65536, "cashback_vesting_period_seconds": 7776000, "witness_pay_per_block": 500000, "committee_proposal_review_period" : 300 } true
approve_proposal init2 1.10.4 {"active_approvals_to_add" : ["init2", "init3", "init4", "init5", "init6", "init7", "init8", "init9", "init10"]} true
get_block 299579
get_block 299596

As you might guess from these commands, the change will take effect at (the next maintenance interval after) 19:45:00 UTC today (2015-09-29).

In the live network, changes to parameters will require approval of committee members elected by the community and require a two-week waiting period during which no new approvals can be added.  To better enable us to test the system, we turned the waiting period way down for the testnet (and this parameter change will lower it even further to 300 seconds), and voted the init witnesses as committee members.

We've also traced why the total witness budget wasn't a round number.  Due to the lower block interval and extra CORE balances we added to the testnet genesis, the requested witness pay was being capped by the hard-coded limit on the rate of creating CORE.  As stated in https://bitshares.org/technology/stakeholder-approved-project-funding/ the maximum rate at which CORE can be created to pay witnesses / workers is approximately 5 BTS per second (the actual number is reserve * 17 / 2^32).  But there are 500M+ extra test CORE in the testnet genesis which will not exist in the real genesis, and this depleted the reserve down to about 3 BTS per second -- so witness funding at 10 BTS every 3 seconds was a little over the limit.

I don't know if we'll have the GUI for creating and inspecting parameters and proposals ready for the launch.  But this test proves the blockchain and command line interface for it is working, so if the community has a desire to change parameters soon after the launch, it should be possible for the committee members elected by the community to enact any desired changes.
