He highlights how he primarily utilizes testnet to identify consensus bugs in his utreexod implementation, appreciating the network's unpredictable nature due to its frequent block bursts and reorganizations. This unpredictability, according to Lopp, serves as a beneficial feature rather than a hindrance, facilitating rigorous testing environments.

Lopp acknowledges the declining efficiency of mining in distributing testnet coins, as evidenced by the reduced block reward of approximately 0.014 TBTC. However, he does not view this as a significant issue for his purposes, since signet—a separate test network—adequately meets the needs of developers requiring a more stable environment for testing scripts and wallets. Despite this, he notes that signet does not replicate the specific elements of testnet that are crucial for his testing scenarios.

An interesting aspect of Lopp’s contribution is his mention of an edge case bug within testnet that periodically resets the difficulty level to one, thereby causing disruptions. He perceives this bug as an integral part of testnet's value for testing under extreme conditions, even providing a link for those interested in exploring the phenomenon further: The Block Storms of Bitcoin's Testnet.

Addressing concerns about the potential valuation of testnet coins by non-developers, Lopp expresses curiosity about the scale of this issue and seeks additional information. He questions whether a network reset would be necessary or beneficial, suggesting that a simple fix could address any immediate problems without the need for a comprehensive reset or the introduction of a Bitcoin Improvement Proposal (BIP). Ultimately, Lopp opposes the idea of completely replacing testnet with signet, as he values the unique features and challenges presented by testnet that are absent in signet.
