Polyhedra (ZK): The Indian Summer of the Interoperable Big Three

Original author: BMAN, ABCDE Lianchuang

Editor’s note: Last month, the fifth round of financing for the Web3 full-stack interoperability infrastructure Polyhedra Network ended , total financing has reached US$75 million. The Bitcoin cross-chain message transmission protocol based on zkBridge launched by Polyhedra Network expands the functions of Bitcoin and enables it to be seamlessly integrated with a variety of blockchain networks, including various first- and second-tier blockchain networks. Interoperability. In the next few months, the tokens of interoperability projects Wormhole and LayerZero will also be launched one after another, which may set off a boom on the track. ABCDE Lianchuang BMAN shared his analysis of Polyhedra on X, and BlockBeats reproduced the full text as follows ：

Recently, the three interoperability giants have been launched one after another, which will set off an Indian summer on the interoperability track.

@PolyhedraZK $ZK will be online in March;

@wormholecrypto $W will be online in April;

@LayerZero_Labs is expected to be launched in Q2.

Among them, Polyhedra is the only ZK player, and also grabbed the beautiful $ZK Ticker, completed a US$1 billion financing led by Polychain, and became a veritable ZK player. Interoperability leader.

In the past three years, more than 20 PhDs and cryptography experts from the Polyhedra team have made dozens of breakthroughs around ZK interoperability. DeVirgo and Virgo invented by Polyhedra are One of the fastest ZKP protocols currently. Ordinary users using laptops or mobile phones can become Prover without downloading large amounts of data from the server (which is well known to be a problem in the industry).

deVirgo has near-perfect linear scalability, demonstrating that build times can be reduced by nearly M times in a distributed computing network with M computers. Furthermore, in deVirgo, communication across the distributed computing network is minimized in the main computation (GKR part) in Virgo. Using deVirgo, zkBridge's proof generation speed can be further improved, up to 100 times faster than using single-threaded Virgo.

In the past three years, Polyhedra has made three important technological breakthroughs based on zk:

1. zkBridge and zkLightClient

Polyhedra invented the industry's first zkBridge. zkBridge was born out of the 2022 ACM CCS paper at the top network security conference, and the mentoring professor is an academician of the National Academy of Sciences. A16z Dan Boneh, chief scientist of Crypto and cryptography technical consultant of Vitailk: https://dl.acm.org/doi/10.1145/3548606.3560652…

In the past 3 years, on-chain users have sent more than 20 million cross-chain transactions through zkBridge across millions of wallets, 25 chains and more than 80 ecosystems.

The ZK light client zkLightClient invented by Polyhedra also provides over 4.5 million message transfers for Layer1 and Layer2 interoperability. LayerZero, one of the three interoperable giants, is also using zkLightClient as the default decentralized verification network (DVN).

2. Ethereum full node certification:

Polyhedra uses ZK to enhance BLS signature verification, Significantly reduces the communication size between Ethereum validators and full nodes. This innovative enhancement paves the way for Ethereum to be more streamlined and scalable. The zk light client zkLightClient enables every validator to sign every block, allowing a single zk-proof to verify 512 BLS signatures, requiring only 200 to 300 Bytes of communication.

The single-slot finality (SSF) created by Polyhedra also significantly reduces Ethereum’s latency. It is combined with the advanced ZKP deVirgo and improved signature scheme to enhance the speed and user experience of Ethereum. It is also one of Vitalik's most valued Ethereum milestones.

3. Bitcoin interoperability:

In the early stages of development, the Bitcoin ecosystem has already There are dozens of Layer 2 players vying for the top spot, but dozens of Layer 2 players are also in urgent need of interoperable infrastructure. Polyhedra is the leader in the interoperability of the Bitcoin ecosystem.

zkBridge already supports the greatest interoperability of the Bitcoin ecosystem, connecting Bitcoin wallets, Layer 2, DeFi and infrastructure. Even between Bitcoin and other chains, trustless interoperability can be carried out based on ZK.

Conclusion:

In the past 3 years, Polyhedra invented the fastest ZK algorithm deVirgo. Connecting more than 25 networks, completing 40 million zk proofs, 20 million cross-chain transactions, and each transaction only requires 1 message. In comparison, Wormhole requires 1 billion messages to verify a total of 3 million transactions. Polyhedra is currently the most efficient leading interoperability project.

In the next few years, we expect to achieve 1000x performance improvements in mathematics and ZKP, which will enable the vision of fully interoperable blockchains. In the future, chains will realize:

1. Interoperability of assets;

2. Interoperability of information;

3. Protocol interoperability.

In the future, the protocol of chain A can be automatically combined and interoperable with the protocol of chain B, and the chains will become interconnected with thousands of chains. And Polyhedra, like its Chinese "polyhedron", has become the infrastructure for the interconnection of thousands of chains.
