Today we introduce Citrea, which is the first ROLLUP to enhance the Bitcoin block space function through zero -knowledge technology.
Bitcoin’s scalability pattern has long been relied on solutions to transfer security and demand to chains and Bitcoin.Citrea will achieve Bitcoin expansion through zero knowledge proof, thereby changing this reality and ensuring the verification and data availability on the chain in the Bitcoin network.This method makes Citrea the first scalable solution that enables more complex applications without damage to Bitcoin security and changing its consensus rules.
The problem of creating new block space
Bitcoin has the safest, decentralized and anti -review block space.The expansion proposal to create a new block space cannot inherit any of these attributes of Bitcoin.These proposals or implementation only provide alternative block space; they do not extend the Bitcoin blockchain.In the long run, the side chain will compete with Bitcoin with an alternative block space, and the risk of user funds through unsafe bridges and network construction.
Bitcoin block space demand is very large
Due to the security, decentralization and anti -review of Bitcoin, people require Bitcoin to meet all their chain needs.In the past few months, we have observed that people’s interest in Bitcoin block space has exponentially increased, which is reflected in the cost rate.Whether it is payment or inscription transaction, people want to be included in the block space and are willing to pay for it.Ensuring the sustainable participation of the Bitcoin network is essential for its long -term steady development, but weighing: Due to high costs and necessary block size restrictions, some transactions will inevitably exclude certain transactions.Bitcoin must expand without changing its core principles to contain more complex transactions.
This growing interest highlights a major problem in existing existing scalability proposals: they fail to solve the problem of continuous increase in demand containing Bitcoin block space.
Existing scalability proposals cannot expand Bitcoin
Bitcoin has been facing more transactions and making wider applications possible for a long time, while not harming its security or core principles.This problem is proven to be difficult to solve completely.Some attempts are designed to increase the payment throughput of Bitcoin, such as the Lightning Network, while others focus on expanding the functions of BTC assets, such as the side chain.Although the first expansion proposal failed to be programmable in Bitcoin, the latter missed a key point: the positive and effective use of the Bitcoin blockchain itself.
In current cases, the inherent demand of Bitcoin blockchain has been redirected to an independent consensus agreement, namely the side chain.This method will generate a trade -off -in order to reduce costs and provide more use cases for BTC, it sacrifice the security of Bitcoin and is not coordinated with its incentive mechanism.Therefore, Bitcoin, led by the side chain, is affected by the influence of expansion solutions for long -term health and incentives to provide services in any meaningful way.Although these solutions are from goodwill, they do not run on the Bitcoin blockchain, nor do they contribute to the security of Bitcoin, and eventually cannot meet the expansion required by the Bitcoin blockchain.
Once the emphasis is emphasized, the transfer of Bitcoin’s demand to the side chain is not equivalent to the demand for Bitcoin.
Extend the Bitcoin block space
Real expansion of Bitcoin requires the establishment of a symbiotic relationship between Bitcoin and expansion solutions.Extended solutions must actively and effectively use Bitcoin’s block space to meet demand and improve their expression and throughput without changing their protocols.Expanding Bitcoin’s block space is the only way to trade in Bitcoin’s security.Any other alternative can inherit the complete Bitcoin security.
The execution of verification and data on the chain is the safest and most consistent way to expand the Bitcoin block.The only way to realize the provenability of Bitcoin is to use zero knowledge or fraud proof.Because fraud proves that a large amount of data requires a large amount of data to be written into Bitcoin, ZK proves that the most effective way to verify the effectiveness of Bitcoin in the block size limit.
ZK Rollups creates a execution shard and processes multiple transactions on the shard. At the same time, it uses concise mathematical proof and minimum necessary data to verify that they are reconstructed on the chain.This method enables ZK Rollups to use the underlying block space in the most effective way and expand L1 with its complete security.
Enter CITREA: Large -scale Bitcoin Security
Citrea is the first Rollup running on Bitcoin, which adds the effectiveness of the Bitcoin block space.Citrea keeps Bitcoin’s demand in its network and ensures that the Bitcoin network is used as the data availability and settlement layer of Citrea transactions.Citrea does not need to change consensus on Bitcoin.
Citrea represents an important milestone of Bitcoin: it is the only execution layer settled on Bitcoin, the first ZK certification verification, and the first general L2 verification within Bitcoin.Citrea’s mission is to promote Bitcoin to enter the next stage and become the basis for the world’s financial infrastructure. Developers can build everything on Bitcoin.
CITREA batch thousands of transactions, process them through ZKVM, and generate concise valid proof to assert the correctness of execution and the correctness of the output data.In the history of Bitcoin, Citrea’s effectiveness has proven to be engraved on the Bitcoin blockchain for the first time and conducts local verification.Citrea is equipped with a local ZK certification verification smart contract on Bitcoin L1, which is built on Bitvm.Unlike a single side chain, Citrea has created a modular Bitcoin world through its execution shards, which keeps settlement and data availability on the chain, that is, on Bitcoin.
Citrea: Bitcoin modularization
Citrea has created stable cost income for miners through data availability. It proves that the BTC is extended to Bitcoin without trust through effective proof, and allows developers to build any applications on its EVM equivalent.
Expand Bitcoin security
Citrea is the only execution layer on Bitcoin.Each transaction that occurs on Citrea is completely protected by zero knowledge and verified by Bitcoin.Citrea’s execution environment is not trusted than Bitcoin, and all participants on the Bitcoin network are accessible.
Therefore, Citrea ensures that data availability, anti -review and reorganization guarantee that meets Bitcoin equivalent.
Bitcoin as application cornerstone:Citrea’s mission is to build a programmable liquidity layer on the safest and decentralized blockchain Bitcoin.We believe that Bitcoin’s block space must be used to set up various financial activities efficiently, such as buying BTC without trust, using BTC or borrowing BTC.Most existing meta protocols that try to provide these functions are trusted and inefficient.Citrea is the most efficient and secure platform for applications on Bitcoin.
Bitcoin settlement and minimum trust two -way hook:For the first time in the history of Bitcoin, a universal L2 settled on Bitcoin, realizing the first universal minimum trust two -way hook in history.Before Citrea, the Layer 2 solution depended on the most signature of the integrity of the multi -signature, such as open or closed alliance.Through Citrea, as long as a network participant is honest, you can verify the validity proof on Bitcoin.Bitvm is based on fraud proof, which means that Citream’s ZK proves are optimistic verification on the Bitcoin network.In the future, a ZK certification verification code operation code will realize a two -way hook mechanism with completely unb Young.
EVM equivalent:When constructing Citrea, EVM equivalent is used, enabling all EVM developers to easily build applications on Bitcoin.Citrea is equipped with a Type 2 ZKEVM, which is completely equivalent to EVM and is built using Risc Zero.In design, Citrea is not limited to a single virtual machine, and due to its modular architecture, new virtual machines can be used in the future, such as WASM virtual machines.
Next plan?
Internal devnet is enabled
We are running Citrea to develop the network internally, and use the synthetic local BTC for key infrastructure integration and testing.The two -way hook with BITVM’s minimum trust is actively developing.
For the first time, the minimum trust two -way hook
Please pay close attention to the disclosure of Citrea’s minimum trust two -way hook design.We will announce our bridge design and open source in the next few weeks!
Public test network
We are making rapid progress.We have been working hard to build the first Rollup steady test network on Bitcoin.We are glad to share more information in the next few months.Please pay attention to our social media and blogs.
Construction with Citrea
Our developer contact form is open today.Citrea has been hatched by Chainway Labs for more than a year and has sufficient funds.
Make Bitcoin the foundation of world finance
Citrea’s vision is to build scalable infrastructure, advance Bitcoin to its next stage, and become the cornerstone of world finance.To achieve this vision, we believe that the block space of Bitcoin must be enhanced, including more transactions and providing more expressiveness and functions without changing its consensus rules.
Bitcoin is perfectly positioned as the cornerstone of the world finance with its security, decentralization and anti -examination.With this potential, Citrea relies on these advantages and makes Bitcoin the base layer of a dynamic Defi, games, NFT and other ecosystems.Citrea will become larger and advanced with its modular world with Bitcoin as an anchor.
We are very optimistic about ourselves and are committed to striving for this goal.
On Bitcoin, for Bitcoin.
