Introduction to xHalfLife

1. Historical practice and introduction of capital flow

Compound Finance simplifies block-based rewards, compound interest calculations, and delayed distribution, saving Gas.

Sablier Protocol is a real-time financial protocol on Ethereum, which supports continuous, self-owned, and trustless bills. However, because this form of the statement of funds is agreed upon by the creditor (employee) to the debtor (employer), it can also be used to repay loans in a current flow.

xHalfLife focuses more on effective equity incentives, that is, employers provide employees with continuous, self-owned, trustless, and time-fair equity.

2. xHalfLife Protocol: Thinking, Improvement and Implementation

2.1 xHalfLife design

Generally speaking, even if Internet employees are excellent, there is no way to choose a private equity incentive distribution (Vesting) plan based on the convenience of company management.

The Internet industry (take Silicon Valley as an example) is generally 4-6 years of Vesting, limited unlocking (1/4 per year, 4 consecutive years, 1/6 per year, 6 consecutive years), and accelerated unlocking (15%) 25% 25% 35% 4 years).

Because the ETH-based money streaming protocol benefits from blockchain accounting technology and delayed issuance, it can achieve near-real-time funding at the lowest cost. Because of the gas fee, you don't need to withdraw the extractable part of the stream at any time.

The xHalfLife protocol is designed to be faster and slower. Any excellent company such as nVidia and Intel is growing exponentially in market value. People who are not good at waiting may be eager to cash out due to difficulties in living. When the company's value was low, these people cashed out a lot of stock chips. We hope that such a design can flow smoothly.

Inspired by the half-life of radioactive elements, we designed xHalfLife as follows:

The parameters of the xHalfLife protocol have 4 parameters: NumStart, K, ratio and eps. Under this protocol, the user's funds are divided into two parts:

Delayed income and recorded income.

Any income goes directly to delayed income.

The funds in the delayed income, after the contract deployment starts, after NumStart blocks, whenever the blockchain height can be divisible by K, and the delayed income balance exceeds the minimum issuance standard eps, the income under the delayed income item will be ratio⋅Delayed income is transferred to the entry income.

The half-life is estimated as −K/log2 ​(1−ratio)∗13.1s

That is, half of this time unlocked.

If the company's development speed can double every half-life cycle valuation, employees will not have any pressure on unlocking equity to improve their lives. If the half-life cycle is longer and the company develops faster, even if the employees are unlocked, the total residual valuation will still exceed the total valuation of the company's shares previously held.

2.2 xHalfLife's implementation method based on Ethereum

For technical reasons, other operations can be replaced by addition and subtraction.

Then the display precision is solved with decimal (uint + floating point position).

There are two implementation methods:

  • For a single stream, the founder locks the warehouse and gives a solution that can be calculated continuously or discretely

  • Multiple equivalent streams, pending gives a solution for continuous calculation

Release speed: the same ratio∗K can be regarded as approximately equal release speed.

3. Explanation of terms related to xHalfLife

Stream: the capital flow of funds(tokens) created ;

Sender: the capital flow of funds(tokens) is created and sent by this address;

Recipient: the capital flow of funds(tokens) is sent to this address;

Deposited: The number of tokens that the sender has pledged in the corresponding capital flow;

Withdrawable: The number of tokens that the sender can redeem in the corresponding capital flow;

Startblock (When Should Start): From which block to start deploying the capital flow of funds you want to create. Here we will display 10 blocks ahead of the current mainnet block by default. You can also query through https://etherscan.io/blocks and fill in the appropriate block yourself. Note: Do not fill in outdated blocks.

Status: the current status of the capital flow. There are three states: Waiting (the flow is waiting for execution to take effect); Streaming (the flow is executing); Ended (the flow has ended).

Unlock K Block: means that every K blocks, the capital flow you have created sends a fund (token) corresponding to the unlock ratio to the recipient;

Unlock Ratio: means that the proportion of each unlock amount to the total funds (tokens) of this capital flow.

Fund: means that you can add funds (tokens) to the capital flow that you have created and are still in the process of execution, and the interval block K and the unlock rate are unchanged.
