Opinion:
Zhixiong Pan: 2025 marked a qualitative shift in the Bitcoin community's attitude towards the threat of quantum computing, moving from theoretical discussions to engineering preparations. BIP360 was assigned a number and renamed P2TSH (Pay to Tapscript Hash). This was seen as an important stepping stone for quantum hardening and also more generally served certain Taproot use cases (such as commitment structures that do not require an internal key). At the same time, the community explored more specific quantum-secure signature verification schemes, including constructing Winternitz signatures with OP_CAT under the premise of introducing corresponding scripting capabilities in the future (such as reintroducing OP_CAT or adding signature-type opcodes), discussing STARK verification as a native scripting capability, and optimizing the on-chain cost of hash signature schemes (such as SLH-DSA / SPHINCS+). This year was a year of intensive discussion on soft fork proposals, with a core focus on how to unleash the expressive power of scripts while maintaining minimalism. Contractual proposals such as CTV (BIP119) and CSFS (BIP348), as well as technologies like LNHANCE and OP_TEMPLATEHASH, are all attempting to introduce more secure "restrictive clauses" for Bitcoin. Furthermore, OP_CHECKCONTRACTVERIFY (CCV) has become BIP443, and various arithmetic opcodes and script recovery proposals are queuing for consensus. These seemingly obscure upgrades are actually adding new "physical laws" to the global value network. They are expected to make the native "vaults" type construction simpler, more secure, and more standardized, allowing users to set mechanisms such as delayed withdrawals and reversal windows, achieving "programmable self-protection" from the perspective of protocol expressibility. At the same time, these capabilities are expected to significantly reduce the interaction costs and complexity of layer-two protocols such as the Lightning Network and DLC (Discrete Logarithmic Contracts). The Lightning Network saw a major breakthrough in usability in 2025: Splicing (hot channel updates). This technology allows users to dynamically adjust funds (deposit or withdraw) without closing the channel, and it currently has experimental support in the three major implementations: LDK, Eclair, and Core Lightning. Although the relevant BOLTs specifications are still being refined, significant progress has been made in cross-implementation compatibility testing. Splicing is the key capability for "adding or subtracting funds without closing the channel." It is expected to reduce payment failures and operational friction caused by the inconvenience of adjusting channel funds. Future wallets are expected to significantly reduce the learning cost of channel engineering, allowing more users to use LN as a payment layer close to a "balance account," which is a key piece of the puzzle for Bitcoin payments to become widely used in daily life.
