Protocol Embedded Staking –
A new way of stabilizing crypto tokens
Staking and Proof of Stake (PoS)
The main idea behind the Proof-Of-Stake concept is that participants can lock coins (their “stake”), and at particular intervals, the protocol randomly assigns the right to one of them to validate the next block. Typically, the probability of being chosen is proportional to the amount of coins — the more coins locked up, the higher the chances.
This way, what determines which participants create a block isn’t based on their ability to solve hash challenges as it is with Proof of Work. Instead, it’s determined by how many staking coins they are holding.
Staking cryptocurrency means that you are taking responsibility to transactions and to support the network by using your cryptocurrency holdings as a guarantee. In order to do this you have to lock a certain amount of tokens, in order to confirm this guarantee. In exchange for locking tokens and strengthening the network this way, users will receive a reward or interest in the form of extra tokens. Thus with staking you can generate a passive income by holding (and locking) coins.
Often in colloquial language the term staking is taken as a synonym for this aspect of generally earning extra tokens by holding on to the coins a user owns, without attaching importance to the technical details described above.
Market effects of Staking within Proof of Stake
Typically there are certain requirement on amount and locking duration within Proof-Of-Stake networks. Only certain minimum amounts of tokens can be staked for at least a minimum amount of time. Although this is very reasonable from a security perspective, these conditions lead to market effects which aren’t always welcome by token holders: At the end of locking periods users feel an incentive to claim the rewards they had been waiting for while their tokens had been locked away and thus had not been usable by them. The end of a staking period leads to a higher probability of tokens being sold on the market, which in turns can lead to some selling pressure and dropping market prices.
Moreover users cannot work with the tokens they hold during the locking period. Therefore classical staking is in competition to generating profit by using DeFi products like lending, participating in liquidity pools or similar.
Protocol Embedded Staking (PES)
Protocol embedded staking was invented in reaction to the disadvantages described above. Although the mechanism of protocol embedded staking is not suitable for the basic infrastructure currencies themselves, it can be an interesting alternative for tokens setup on top of these currencies, for instance for ERC20-tokens within the Ethereum blockchain.
Protocol Embedded Staking (PES) is anchored in the base code of the currency’s smart contract and does not require any explicit control or triggering by the user. All wallets holding tokens automatically and permanently take part in the staking process. Obviously, the term “staking” is used in colloquial manner here, since no tokens have to be locked here. Nevertheless, the main idea of strengthening the stability of the currency by creating an incentive to hold on to the tokens acquired is well fulfilled.
Algorithms for protocol embedded staking work by regularly inflating the total token supply according to a mathematical logic implemented into the smart contract. Account balances are defined by their individual share of the total supply thus guaranteeing a non-dilutive allocation of tokens. This way the relative staking profit is and remains equal for all accounts independent of size and user related parameters like staking duration, choice of staking pool etc.
The mathematical basis for this kind of staking should follows the some specific characteristics:
• Transparent supply calculation predictable for investors
• Stability of the calculation towards user behavior and network effects
• Effectiveness of the calculation regarding computing power and thus gas
Advantages for Currency Holders
The technical attributes described above facilitate some special advantages holders of crypto currencies constructed in this way can expect:
Since Protocol Embedded Staking allows complete availability of token usage in DeFi products, staking rewards will always be payed additionally to fees users may earn by using DeFi products. This way users can accumulated several income stream and multiply their benefits.
Staking being embedded within standard ERC20 transfer functions leads to a complete automation of the staking process with no need for user decisions or interactions to receive rewards.
Tokens implementing PES stay compatible with the protocols of the base currency they are built on. For example, coins set up as ERC20 tokens can be used within all DeFi products created for this protocol, like pooling, lending, yield farming, mining and so on.
Protocol embedded staking evenly adjusts all balances relatively to the balance values. No other preference whatsoever is given to any specific holder. All wallets are treated in the same way, independent of transaction volume or other parameters.
Since the staking algorithm is the only way of inflating the supply, there is absolute transparency concerning the total and circulating supply of the tokens. This accounts true if no extra minting or burning methods are implemented, of course. Many crypto currencies with big market caps do not have clear transparency of circulating supplies making it more difficult to assess their actual market values.
As described above staking tokens based on PES does not create any incentives for cyclical dumps at the end of locking periods.
Examples for Protocol Embedded Staking
For the time being Savix.org is the only cryptocurrency token implementing protocol based staking.
The Savix supply development curve is gradually defined by a sequence of straights (gradient) which determines the interest rate at a specific point in time. Start and end points (corner points) of these straights define the global shape of the supply curve. Each straight is defined by the equation
F(x) = (Xt — X1) * [(Y1 — Y1) / (X2 — X1) ]
The following diagram shows the temporal development of a starting investment of 100 SVX.
The mathematical function and thus the exact numbers are flexible of course. But the graph illustrates well, that the exact return for any time in the future can be calculated beforehand, making the staking process as a whole completely transparent.
Details on the mathematics used is the example above can be found in the whitepaper of the project linked from their website savix.org.
