So let's analyze what risks and compromises lie behind this 'minimized trust' and DeFi overlays on Bitcoin.
1. BitVM bridge with minimized trust
Reality of trust. Any bridge is a potential 'bottleneck' of security. Even if 'minimized' trust is claimed, it usually means that part of the operations is verified off-chain and then aggregated on-chain. The question arises: who and how ensures honesty? These could be validator operators, oracles, or multisigs, and all of them are potential points of failure or attack.
Possible attacks. The history of DeFi is full of examples where bridges were hacked due to insufficient transparency or verification errors. Security support without strict decentralized guarantees is often impossible.
2. Yield-bearing asset YBTC
Token economics. Creating a yield-bearing asset is a classic way to attract liquidity. But without a transparent emission mechanism, staking, or backing by real value, this is more of a financial pyramid.
Risk of inflation and devaluation. If the token simply 'issues' income from new investors (like many early DeFi projects), sooner or later liquidity will dry up, and the price will fall.
3. Bitcoin Rollup
Complexity and scalability. Rollup is a layer 2 solution designed to offload the main chain by collecting multiple transactions into a single commit to the blockchain. But Bitcoin, compared to Ethereum, is a more limited environment for such solutions.
Technical limitations. For example, Bitcoin's scripting model is less flexible, and implementing a full Rollup without compromising security and decentralization is extremely difficult.
Trust in aggregators. Like with the bridge, Rollup requires operators or validators that users are forced to partially trust.
4. Full-fledged DeFi infrastructure
Fundamental problem. Bitcoin was not originally designed for complex smart contracts that DeFi services allow. Different projects try to 'work around' these limitations, but this often leads to compromises in security.
Integration risk. Adding DeFi to Bitcoin requires new layers — each of them expands the surface for potential vulnerabilities.

Conclusion: behind all these loud words lies a classic dilemma — either we maintain Bitcoin's rock-solid security and decentralization but without complex DeFi and scalable solutions, or we sacrifice part of that security for new opportunities. Claims of 'minimized trust' should be seen as marketing, and the actual architecture should be studied thoroughly before trusting your funds.
