Token Economic Analysis

1. Impact on Network Security

The requirement for Validators to stake tokens provides a dual benefit: it secures the network by putting capital at risk and ensures that Validators are invested in the network's longevity. The auction-based system for Validator selection introduces a competitive and meritocratic element, ensuring that only the most committed and capable Validators secure their positions.

2. Network Fee Structure

Projecting the network's potential revenue based on current DeFi volumes reveals the immense potential for value accrual through the fee mechanism. With a conservative estimate, the annual burn rate could create a significant deflationary impact on the $XPORT token, benefiting holders and reinforcing the network's value proposition.

a. Fee Utilization

As of the date of this writing, the combined daily volume of the top 20 Decentralized Exchanges is ~$4.5B. The current average maker/taker fees at DEXes is ~0.18%. Given the efficiency of Layer 2 swaps enabled by Portal which are much less expensive than other DEXes, we can safely assume that a 0.125% fee is low enough to attract users while still generating a meaningful revenue for Validators as well as for per Epoch token burn. As a hypothetical scenario (assuming current volumes, prices and other variables), at 10% DEX volume penetration, it would roughly be equivalent to $100M of $XPORT burned within the first 12 epochs, while another $100M is expected to be distributed to the Validators in the first 12 Epochs. Combined, these advantages could make the Portal Network quickly hypercompetitive in the DeFi space, attracting more users and, consequently, more fee revenue for burning and drive the feed forward loop of better yields > more TVL> better yields, as long as the demand for trust minimized, cheap, fast spot markets exists and grows.

b. Economic Impact

The Portal Network's token burning mechanism is a pivotal feature. By using half of the swap fees to purchase and burn $XPORT tokens, the network ensures a consistent demand for the token. This process not only reduces the overall supply but also helps stabilize and potentially increase the network’s market value.

c. Strategic Implications

The interplay between market activity (swap fees) and token scarcity (burning) creates an economic environment where the token's value is intrinsically linked to the network's usage. As the network grows and swap volumes increase, the burning mechanism could significantly enhance the token's attractiveness to both Validators and Holders.

3. Validator Economics

a. Yields and Lockups

The yield dynamics for Validators are complex. Since rewards are not directly proportional to stakes, this could encourage a more diverse Validator set, preventing collusion and potential consensus failure. This system also promotes efficiency as Validators are motivated to optimize their bids and operations to maximize returns.

b. Slashing and Penalties

The slashing mechanism, while a standard in many networks, is particularly significant in the Portal Network. It ensures Validators act in the best interest of the network. Burning the slashed tokens adds to the deflationary aspect of the tokenomics, reinforcing the token's value.

One key difference between Portal’s non-custodial structure and competitors like THORChain and Chainflip is that even in the case of a Byzantine Failure, users’ and Liquidity Providers’ funds will be safe (due to the non-custodial delegation in the ADMM)

4. Long-Term Sustainability

a. Balancing Emission and Burning

Maintaining a balance between token emissions and burning is a delicate task. The network must regularly assess and potentially adjust its policies to ensure the burning rate is effective in creating a deflationary environment without compromising network security and Validator incentives.

b. Adaptability and Governance

The network's long-term success will hinge on its adaptability. Effective governance mechanisms proposed by the community and accepted by a majority of the Validator network and stakers enable timely responses to market dynamics, technological advancements, and community needs.
