The Web Laptop Protocol (ICP) plans to make use of superior threshold cryptography to unlock decentralized finance capabilities and sensible contract performance on Bitcoin’s base layer.
Chatting with Cointelegraph throughout Paris Blockchain Week, Dfinity senior analysis scientist Aisling Connolly outlined how ICP’s integration of threshold-Schnorr signatures will allow the protocol’s sensible contracts to acquire addresses and authorize transactions on to the Bitcoin blockchain.
Schnorr signatures are a selected kind of digital signature named after mathematician Claus Schnorr. They work like a secret handshake between two events, proving that one particular person has signed off on one thing with out revealing their secret code.

The implementation will enable ICP sensible contracts to signal Schnorr signatures to etch Bitcoin Runes, inscribe Ordinals in a decentralized method, ship, obtain and bridge BRC-20 tokens straight on the Bitcoin base layer, signal taproot transactions and re-inscribe Ordinals.
ICP anticipates the complete implementation of threshold-Schnorr to be launched halfway by 2024. ICP integrates the core implementation of threshold-Schnorr-BIP340, which allows sensible contracts to derive addresses and authorize native Bitcoin transactions.
“Schnorr permits additional performance, like batching transactions. It additionally permits for brand new use circumstances which can be creating on Bitcoin. You see folks inscribing Ordinals during the last yr, it should assist do that with none tweaks and from different chains,” Connolly explains.
The researcher added that the power to inscribe Ordinals or etch Runes following the Bitcoin halving typically requires utilizing Schnorr signatures. Connolly stated Schnorr signatures are much like ECDSA signatures that Bitcoin makes use of to manage its possession, however the former is “less complicated, sooner and safer.” She stated:
“In case you have Schnorr as a local factor, then it permits sensible contracts to straight write or etch runes on the Bitcoin blockchain. That is fairly particular. I don’t know anybody who’s doing this for the time being.”
The hope is that combining Schnorr signatures with ICP’s protocol-level integration with the Bitcoin community will open prospects for decentralized purposes (DApps) and providers that may leverage the liquidity and safety of Bitcoin with out counting on centralized bridges.
Connolly highlighted a handful of working use circumstances which can be already being explored and constructed by ecosystem builders.
“One use case is ICP serving as this orchestration layer. Let’s say you’ve gotten an current DApp on Ethereum, and also you wish to leverage Bitcoin. You possibly can have an ICP sensible contract that works alongside it to speak and write to Bitcoin,” Connolly explains.
Others are constructing purposes from scratch utilizing ICP. Connolly highlighted Taler DAO, an algorithmic Bitcoin-backed stablecoin, for instance of recent experiments utilizing the infrastructure.

One other consideration is how the combination will probably be obtained by the broader Bitcoin group. “OG” Bitcoiners are usually skeptical of integrations and options that promise to bridge the preeminent cryptocurrency and its underlying blockchain to different chains.
Connolly stated conversations with Bitcoin proponents counsel that there’s an open perspective towards infrastructure that broadens the utility of Bitcoin:
“A few of the work that we’re doing is being picked up by Bitcoiners and within the BitVM Telegram chat, they’re discussing the stuff that we’re doing and the way it may be used.”
The researcher believes the Bitcoin group is usually open to exploring and contemplating utilizing instruments like decentralized exchanges on ICP that helps noncustodial wallets. Connolly stated this is able to enable DeFi capabilities like staking Bitcoin with out relinquishing management of a consumer’s personal keys.
“If Bitcoin is the form of de facto retailer of worth in a digital foreign money like cryptocurrency, why can it not be the form of de facto like hyper-secure compute platform as effectively?”
ICP now has over 300 builders constructing Bitcoin-enabled DApps within the area of DeFi, NFTs, gaming and social media. ICP launched Bitcoin integration in 2022. Utilizing chain key cryptography eliminated the necessity to use bridges for cross-chain performance, permitting ICP sensible contracts to carry, ship and obtain Bitcoin.
