Tamper protection, tamper protection, immutability… Although blockchain technology has many advantages over centralized servers, the blockchain ecosystem is vulnerable to certain computer hacks, and most notably: bridging attacks. $2 billion has been stolen across bridges since the start of the year, according to specialist firm Chainanalysis.
A “bridge” is a computer protocol that allows two blockchains to communicate with each other. The vast majority of blockchains operate in isolated environments: each has its own rules, mechanisms, and assets that are often incompatible with other blockchains. The proliferation of blockchains (Bitcoin, Ethereum, Solana, Polygon…) and the lack of interaction between them make it necessary to have these bridges that allow a “dialogue” between blockchains.
