Thank you all for playing

Goals for GoS 6 genesis

  • Pretty much like GoS 5
  • Better account list for Adding vesting generate from GoS 1 account list
  • Re-introduce 1 Bitfish validator
  • some minor changes for parameter names introduce in sdk v0.31.0

Game of Stake 5 Removal of the Large Cartel

We will launch Game of Stakes 5 at 15:00 UTC on Friday Feb 2nd.

Game of Stakes 5 represents are rejection of the stake distribution in GoS 4 by the community.

Clearly indicated by the wide social consensus expressed online, in the community forums and the failure of GoS 4 to start.

Long live subjectivity and automated social consensus.

Game of Stakes 4 The Endgame

We are targeting a manadatory software upgrade to Game of Stakes 4 at 12:00UTC on Friday Feb 1st. We will be also adding vesting stake to all game of stakes participants.

The last valid block for scoring on Game of Stakes 3 will be 12:00 UTC 12:00UTC on Thursday Jan 31st.

We exported block 330,000(This was nearest state checkpoing and simple to export) and updated the state to new version.

The genesis file has been published. Genesis time is Feb 1st 12:00 UTC.

Good luck players.

Version for GOS 4.

Game of Stakes 3 the restart

We are excited to resume Game of Stakes in the new year at 15:00 UTC on Jan 3rd.

The new genesis file for Game of Stakes 3 is up.

We are expecting validators to run 0.29.1-0-g6bff708 which is a state machine compatible release that fixes an exploitable coin minting bug.

We are expecting to launch GoS 3 this week and possibly do a hard fork upgrade on Jan 10th.

The holiday hiatus and Game of Stakes 3

We are on a holiday hiatus for Game of Stakes till Jan 3rd.

Check out short video play by play

Here is what we are doing during the holiday hiatus.

  • genki-4000 is running.

  • The genki-4001 upgrade is being planned for Dec 28th. This provide some additional stress testing of export to genesis process that has been a struggle to Q&A.

  • I expect to be posting the GoS 3 genesis.json file before Jan 2nd with a genesis time of Jan 3rd. I am thinking of picking a more asia friendly time.

  • We will be assessing the shortfalls in our QA process on the upgrade process after holidays but I think we can have confidence in a launch of the 3rd because of the prveious two steps.

Upgrade 2.

brought to you by Zaki and Certus One

The genesis time experiment in Upgrade 1 worked perfectly and caused us to start producing blocks and achieve consensus at exactly 2018-12-20 15:00 UTC.

However a bug in the gaiad export for zero height logic caused the chain to halt while committing block 30.

The genesis file could be fixed manually by resetting every height in the genesis file to 0.

To upgrade please download the updated genesis.json. We are still using version 0.29.0-0-g2b3842c58

gaiad unsafe-reset-all <- this is safe since we are starting a new chain

gaiad start with command line flags as appropriate for your node type.

Genesis time will be 2018-12-21 15:00 UTC.

Your node will idle after gaia start and then automatically begin connecting.

Upgrade 1.

brought to you by Zaki and Certus One

We chose a very conservative initial blocksize of 50kb for the initial game of stakes launch as a conservative starting.

With 199 validators online, the signatures in blockheader now take up most of the block.

We will be doing the first network upgrade.

To upgrade, install the new gaiad version v0.29.0 and download the new genesis to your config folder. git fetch --tags git checkout v0.29.0 make get_vendor_deps && make install gaiad version 0.29.0-0-g2b3842c58

gaiad unsafe-reset-all <- this is safe since we are starting a new chain

gaiad start with command line flags as appropriate for your node type.

Genesis time will be 2018-12-20 15:00 UTC.

Your node will idle after gaia start and then automatically begin connecting.

Launch policy

We are delaying Game of Stakes launch based on the demands of the validator community to run a 48hr testnet. Chat here: Riot

The genensis file has been released. Keep reading...

If you're a validator who had to submit a "Simulated Event" form to your cloud services provider, you may want to contact the provider with updated dates for the challenge or resubmit your form to ensure that you are in compliace with your provider's terms of service.

Instructions for Launching Game of Stakes

Welcome to the Launch of Game of Stakes.

You are about to be part of largest experiment in byzantine fault tolernant computer science. Today you an going to help launh the largest Byzantine Fault Tolerant network in history.

This be is the first large scale adversarial BFT network ever.

This will network will be the first demonstration of cartel behavior and censorship in an incentivized network.

We are going to do a decentralized network start. I expect it will take us at least 24 hours. If we don’t start in 24 hours, we will bump the chain id and require new gen-txs. The window to submit a gen-tx will be 2-3 hours if we don't launch.

Doing a decentralized network start of this scale will push Tendermint to it’s limits. I believe it will be possible but every participant is going to have to take enormous care to get their configuration right.

First, triple check your software versions.

gaiad version

Just a note gaia v0.28.1 has been tested to be fully compatible with this chain. You can choose to use the version at launch and we will shorly reccomend all players upgrade.

Next check the timeouts in your config.toml

timeout_propose = "3s"
timeout_propose_delta = "500ms"
timeout_prevote = "1s"
timeout_prevote_delta = "500ms"
timeout_precommit = "1s"
timeout_precommit_delta = "500ms"
timeout_commit = "5s"

Finally, make sure you have the correct genesis.json

shasum -a 256 genesis.json

0e7132b284e8fc8c8e51a90e158204b376d6203e5f12c14e253edbfb38dbebef genesis.json

Once you have double checked all this, gaiad unsafe-reset-all We recommend setting min fees on your sentry nodes via the commandline or gaiad.toml. gaiad start --minimum_fees=1STAKE,1photino.
We would also very much appreciate logs being kept on validator nodes via gaiad start --log_level="consensus:debug,mempool:debug,*:info". After you have gaiad start do not run a reset all again unless we have decided to switch to a new chain id.

Seed Nodes

I'll accept seed nodes as pull requests here.

Games of Stakes scoring will take place at an preannounced blockheight on GoS 4.

Scoring will primarily consider the number of times a validator has been jailed and the duration of jailing across GoS 1 and GoS3.

Among player who are in the top tier of min jailing instances , we will will looks at signed pre commits and accumulated stake for scoing.

Finally there will be bonuses in the allocation for valdiators who have contributed in interesting ways to Game of Stakes and the retrospective
