Wrapped Bitcoin vs. Bitcoin: What are the differences?

Wrapped Bitcoin (WBTC) is a wrapped token that maintains a 1:1 peg with Bitcoin's price, allowing BTC holders to access the decentralized finance (DeFi) ecosystem.

While native Bitcoin (BTC) operates exclusively on the Bitcoin blockchain with a fixed 21 million coin supply, WBTC enables participation in other networks like Ethereum, Solana, Tron, and many others. WBTC is governed by a 16-member DAO including BitGo, Chainlink, and Compound. 

BTC exists natively on the Bitcoin network, whereas WBTC operates as a representation of BTC that can be used on other networks. Native BTC cannot interact with other networks. 

Wrapped Bitcoin (WBTC) enables holders to access a broad universe of DeFi applications. Despite residing on a separate blockchain infrastructure, WBTC tracks BTC pricing precisely and maintains unconditional 1:1 redemption rights. 

Launched in 2008 by the pseudonymous creator Satoshi Nakamoto, Bitcoin (BTC) is the cryptocurrency sector's foundational and most widely adopted digital asset. 

BTC's distinguishing characteristics include its decentralized architecture and its algorithmically enforced maximum supply of 21 million units. These attributes have positioned it as an attractive network for censorship resistant payments and as a hedge against monetary inflation for long-term investors. 

Blockchains generally operate as isolated networks without native interoperability. 

This architectural limitation means BTC holders cannot directly migrate their assets to other blockchains. This creates friction for investors holding substantial Bitcoin positions who wish to participate in DeFi protocols or NFT assets in other ecosystems. 

Wrapped cryptocurrency tokens enable assets from one network to be used within otherwise incompatible blockchain ecosystems. 

WBTC permits unconditional 1:1 redemption for native BTC through decentralized bridge protocols or centralized exchanges. The native BTC, backing the issued WBTC, is secured and managed by a consortium of institutions. WBTC maintains a strong record of security and redeem-ability.

However, wrapped cryptocurrency architectures introduce centralization vectors absent from native blockchain assets. Under these arrangements, WBTC holders face potential asset loss if custodians experience security breaches or insolvency. 

WBTC also relies on smart contract code for minting, burning, and custodial operations. While WBTC contracts have undergone multiple security audits, smart contract vulnerabilities remain a theoretical attack vector that could compromise user funds. 

WBTC is operated by a DAO (decentralized autonomous organization) and secured by multi-signature wallet technology, structures specifically designed to eliminate single-point-of-failure risks. 

The WBTC DAO comprises 17 institutional stakeholders, including cryptocurrency sector leaders such as BitGo, Chainlink, and Compound. The DAO implements collective governance for critical decisions including membership modifications and WBTC smart contract parameter adjustments. 

You can execute Bitcoin-to-Wrapped Bitcoin conversions through centralized cryptocurrency exchanges or decentralized bridge protocols. 

The following platforms facilitate bidirectional BTC/WBTC conversion: 

• Kraken (exchange) 

• Coinbase (exchange) 

• Changelly (exchange) 

Each platform charges varying fee structures for conversion services, typically ranging from 0.1% to 0.5% of transaction value plus applicable network fees.
