Staking and Voting: WAX vs. EOS

WAX differs from EOS in several distinct ways:

Calculating Stake Weight:

As we mentioned in a previous post, voter apathy is a concern for DPoS blockchains. We’ve seen how other DPoS blockchains have been adversely affected by lack of voting. To drive community interest in the voting process, we’ve developed WAX Staking Rewards. The amount of WAX Staking Rewards that a staking WAX Token holder earns is based on their current stake weight. Stake weight for voter i is calculated as:

The above stake weight calculation is similar to EOS’s function, but it’s accelerated to a 13 week half life for WAX instead of the 52 week half life for EOS (if you notice in the equation, we replace double(52) with double(13) in the denominator of weight).

In the last post, we simplified this calculation by stating vote strength was bounded between [0,1]. In the actual implementation, vote strength increases with new votes having more strength than old votes. Thus vote strength doesn’t decay, but new votes have increased weight. Each week, vote strength grows at 5.4766%, and in 13 weeks new votes will double in strength. In contrast, vote strength on EOS grows at 1.34% weekly, and new votes double in strength every 52 weeks. We’ve accelerated the decay rate to encourage WAX Token holders to return to the platform and vote regularly. While EOS uses stake weight only for voting, WAX also uses it to calculate WAX Staking Rewards (and in the future, other types of rewards).

Calculating Daily WAX Staking Rewards:

All WAX Staking Rewards combined (including ones not yet introduced) will equal 2% annual inflation (i.e. 40% of the total annual inflation). At launch, WAX Staking Rewards will be 1% annual inflation (i.e. 20% of the total annual inflation).

The following equations are used for calculating a voter’s daily WAX Staking Rewards (note: details on average guild performance are in the next section).

Calculating stake weight:

We can calculate the stake weight for a voter who has 10,000 staked WAX Protocol Tokens and votes on June 30, 2019.

Calculating total stake weight:

Total stake weight is defined as the sum of all voters’ stake weight.

For simplicity, we will assume all users vote on June 30, 2019 (i.e., everyone has the same vote strength of 2^78.24). At launch, there will be 1,850,000,000 WAX Protocol Tokens eligible to be staked.

Calculating average guild performance:

Average guild performance will be set to 100% (or 1) at launch.

Calculating a voter’s daily WAX Staking Rewards:

In this example, we assumed that every user would vote at the same time. It is easy to show that if the WAX Token holder has been slower to refresh their votes relative to all other voters, then the holder’s rewards would decrease.

In summary, it is important to refresh your vote and to vote for at least 16 different guild candidates. This enables you to maximize both your WAX Staking Rewards and your vote’s power since your guild vote counts more if you refresh your vote.

Calculating WAX Guild and Standby Guild Rewards:

Guilds and standby guilds will share rewards equalling 2% annual inflation (i.e. 40% of the total annual inflation). This amounts to 74,000,000 WAX Protocol Tokens annually (3,700,000,000 * .02) or 202,739 WAX Protocol Tokens daily. The 21 WAX Guilds will share 60% of the reward pool, and each WAX Guild is expected to earn 5,792 WAX Protocol Tokens per day if they produce all their scheduled blocks. The 36 standby guilds will share the remaining 40% of the reward pool, and each standby guild is expected to earn 2,252 WAX Protocol Tokens per day if they produce all their scheduled blocks.



To encourage WAX Token holders to vote for the highest quality WAX Guilds to produce blocks on the WAX Blockchain, in the future WAX Staking Rewards will be tied to the performance of the WAX Guilds that the WAX Token holder is voting for (this is not reflected in the above example since it will not be live at launch).

If a WAX Guild that you voted for is underperforming, your WAX Staking Rewards will decrease.

Your WAX Staking Rewards are scaled by the performance of the WAX Guilds you vote for:

Recall the function to determine a voter’s WAX Staking Rewards proportion:

Therefore, if the WAX Guilds that you vote for only produce 90% of blocks scheduled to them, your WAX Staking Rewards will be 90% of the maximum possible amount. If the WAX Guilds that you vote for produce 50% or less of the blocks scheduled to them, you will not earn any WAX Staking Rewards in exchange for voting for them. In addition, these WAX Guilds will not be paid their WAX Guild Rewards if they produce 50% or less of their scheduled blocks.

This formula applies to standby guilds as well. This means the vote you cast for a standby guild will receive the same potential reward as the vote you cast for a guild that becomes one of the top 21 (i.e. a WAX Guild). This makes you agnostic as to whether a guild that you vote for is likely or not to be one of the 21 WAX Guilds. We want WAX holders to cast their vote for the guild they believe best represents them, without being penalized.

If you proxy a vote to someone who votes for underperforming WAX Guilds, your WAX Staking Rewards are diminished since your rewards are calculated based on the WAX Guilds that a proxy selects for you. Please note that a proxy cannot refresh your vote weight when they vote on your behalf; rather, you must refresh your vote for the proxy you choose in order to regain full vote weight capacity, and consequently, to regain full WAX Staking Rewards capacity.

In the future, a proposal could be submitted to hire an independent inspector general to judge WAX Guild performance. Voters could incorporate this performance reporting from the inspector general in their selection of WAX Guilds and standby guilds.

Standby Guild Readiness Requirements:

Standby guilds are critical to ensuring a robust network with maximum block production capacity. We will allocate 1% of all blocks to be produced by standby guilds. These blocks will be allocated in a pseudorandom manner to the standby guilds. This compels standby guilds to maintain 24/7 uptime since they cannot predict when they will be assigned to produce a block. It also allows for voting on standby guild members.

EOS allows anyone to represent themselves as a standby block producer. Although there are suggested hardware requirements to operate an EOS block producer, there isn’t a test to determine if all producers can actually produce a block. If a lower quality standby producer is voted into the list of top 21 block producers, it is possible that the lower quality producer will be unable to produce its assigned blocks resulting in lower chain performance.

The lower quality producer, however, would still get paid a share of the block reward. EOS block producers and standby producers share 0.75% inflation based on the number of votes they receive. This may give incentive for lower quality producers to promote themselves as a producer without having sufficient block producing capabilities.

The WAX Blockchain uses three mechanisms to address this problem. First, WAX standby guilds must prove their ability to produce blocks in order to be included in the pool of 57 qualified guilds (21 WAX Guilds + 36 standby guilds). Second, as with WAX Guilds, WAX standby guilds are penalized if they can not produce at least 50% of the blocks assigned to them. Lastly, because staking incentives are tied to guild performance, token holders will be economically encouraged to direct their votes to higher performing guilds.

WAX Guilds at WAX Blockchain Mainnet launch:

The WAX Blockchain is optimized for e-commerce and digital items trading. When coupled with our forthcoming microservices layer, we believe the WAX Platform provides the best business and usability experience for dApp developers and customers. To accomplish this result, we have made significant enhancements to the EOS codebase. We are excited to share all the valuable capabilities that can be powered on the WAX Platform. However, we are also keenly aware that WAX's specific combination of custom features, governance protocols, and community incentives is brand new for a DPoS-based blockchain. Accordingly, we will roll out these features over time to ensure that the WAX Blockchain ultimately will self govern in such a way that productive feature enhancements can be easily proposed and timely activated.

As we gradually roll out the self-governance features and incentives, WAX and StrongBlock, a company comprised of founding technical team members of Block.one, the creators of EOS, will initially run the 21 WAX Guilds.

Because WAX and StrongBlock will run the genesis phase of the network, we will not require standby guilds initially. However, we are eager to have more WAX Guilds onboarded as quickly as possible so that eventually all guilds are run by the community. For that reason, guild candidates can begin submitting proposals on June 30, 2019. We will release instructions for applying to become a guild, and specifics on the number of WAX Tokens to be earned from WAX Guild Rewards, before mainnet launch.
