Understanding zkSync (ZK): A comprehensive overview
Introduction to zkSync
zkSync is a Layer-2 protocol designed to scale Ethereum using advanced technology based on zero-knowledge (ZK) cryptographic proofs. Second Bitfinex, zkSync’s main goal is to improve Ethereum’s throughput while maintaining its core values of decentralization, security, and self-sovereignty. This protocol achieves this by using ZK-rollups, which allow transactions to be processed off-chain, then batched and sent to Ethereum in a single proof. This method significantly increases transaction speed and reduces costs without compromising security, making zkSync a solid solution for scaling Ethereum.
Hyperscale and user experience
One of the critical use cases addressed by zkSync is the need for hyperscale in the blockchain ecosystem. Hyperscale refers to the ability to process an unlimited number of transactions without marginal impact on security or cost. zkSync’s ZK Stack framework supports this by enabling the creation of multiple ZK-based blockchains that share users and liquidity, thus distributing the load and improving overall scalability. This approach ensures that as required blockchain applications grows, zkSync can handle the increased load efficiently.
zkSync also focuses on providing a superior user experience (UX). The protocol supports native account abstraction, which allows developers to create user-friendly applications that abstract complex processes such as initial phrase management and gas fare payments. For example, users can schedule and automate payments or pay gas fees in any token, or even have gas fees paid on their behalf. These features are designed to make blockchain technology more accessible and intuitive, paving the way for wider adoption.
Security measures
Security remains a top priority for zkSync. The protocol uses a multidimensional approach to protect users from bugs, exploits, scams and hacks. The zkSync testnet lasted an entire year, during which extensive audits and stress tests were conducted to ensure its robustness. By inheriting the security of Ethereum via ZK-rollup and employing additional security measures, zkSync aims to provide a highly secure environment for decentralized finance (DeFi) applications. This combination of scalability, UX improvements, and security positions zkSync as a key player in the effort to bring Ethereum to a global scale.
What is the ZK token?
The ZK token serves as a native utility and governance token within the zkSync ecosystem, playing a crucial role in maintaining and improving the protocol’s operations. One of its primary use cases is paying transaction fees on the zkSync network. By using paid ZK tokens, users benefit from lower costs than on the Ethereum mainnet, thanks to zkSync’s efficient Layer-2 scaling solutions. This incentivizes users to adopt zkSync for their transactions, thus increasing network activity and liquidity.
In addition to transaction fees, the ZK token is central to zkSync’s governance framework. Token holders can participate in the decision-making process by voting on key proposals that influence the future direction of the protocol. This decentralized governance model ensures that the zkSync ecosystem evolves to reflect the collective interests of its community. Decisions on protocol updates, parameter adjustments and the introduction of new features are made more transparent and democratic through the active involvement of ZK token holders.
The ZK token also plays a critical role in incentivizing network security and participation. Users can stake their ZK tokens to support the network’s security infrastructure. Stakers are rewarded with additional ZK tokens, providing them with a financial incentive to contribute to the resilience and stability of the network. This staking mechanism not only improves security, but also encourages long-term commitment from participants, fostering a stronger and more engaged community.
Finally, the ZK token is used to incentivize the provision of liquidity within the zkSync ecosystem. Liquidity providers are rewarded with ZK tokens for adding liquidity to various pools, which is essential for the smooth functioning of decentralized exchanges (DEX) and other DeFi applications running on zkSync. By offering ZK token rewards, zkSync ensures that sufficient liquidity is available to support high-volume trades and other financial activities, thus improving the overall usefulness and attractiveness of the platform. This comprehensive use of the ZK token across multiple aspects of the ecosystem highlights its importance in driving the adoption and success of zkSync.
ZK Tokenomics
For those interested in acquiring ZK tokens, users can purchase them using cryptocurrency or fiat on platforms like Bitfinex. The process involves logging into a Bitfinex account, depositing funds, and then exchanging for ZK tokens. This flexibility in purchasing options makes it easier for a broader audience to participate in the zkSync ecosystem.

$6.8M Stolen, ASTRO Collapses 60%
In the latest news in the blockchain industry, there has been a turn of events that has severely affected Terra and its users and investors, with the company losing $6.8 million. The attack, which exploited a reentry vulnerability in the network’s IBC hooks, raises questions about the security measures of the once celebrated blockchain protocol.
A web3 security company, Cyvers Alerts reported that the exploit occurred on July 31st and caused the company to lose 60 million ASTRO, 3.5 million USDC500,000 USDTand 2. 7 BitcoinThe flaw was discovered in April and allows cybercriminals to make payments non-stop by withdrawing money from the network.
Earth’s response
Subsequently, to the hack employed on the Terra blockchain, its official X platform declared the Suspension network operations for a few hours to apply the emergency measure. Finally in its sendTerra’s official account agreed, sharing that its operations are back online: the core transactions that make up the platform are now possible again.
However, the overall value of the various assets lost in the event was unclear.
Market Impact: ASTRO Crashes!
The hack had an immediate impact on the price of ASTRO, which dropped nearly 60% to $0.0206 following the network shutdown. This sharp decline highlights the vulnerability of token prices to security breaches and the resulting market volatility.
This incident is not the first time Terra has faced serious challenges. Earlier this year, the blockchain encountered significant problems that called into question its long-term viability. These repeated incidents underscore the need for stronger security measures to protect users’ assets and maintain trust in the network.
The recent Terra hack serves as a stark reminder of the ongoing security challenges in the blockchain space. As the platform works to regain stability, the broader crypto community will be watching closely.

Luxembourg proposes updates to blockchain laws | Insights and resources
On July 24, 2024, the Ministry of Finance proposed Blockchain Bill IVwhich will provide greater flexibility and legal certainty for issuers using Distributed Ledger Technology (DLT). The bill will update three of Luxembourg’s financial laws, the Law of 6 April 2013 on dematerialised securitiesTHE Law of 5 April 1993 on the financial sector and the Law of 23 December 1998 establishing a financial sector supervisory commissionThis bill includes the additional option of a supervisory agent role and the inclusion of equity securities in dematerialized form.
DLT and Luxembourg
DLT is increasingly used in the financial and fund management sector in Luxembourg, offering numerous benefits and transforming various aspects of the industry.
Here are some examples:
- Digital Bonds: Luxembourg has seen multiple digital bond issuances via DLT. For example, the European Investment Bank has issued bonds that are registered, transferred and stored via DLT processes. These bonds are governed by Luxembourg law and registered on proprietary DLT platforms.
- Fund Administration: DLT can streamline fund administration processes, offering new opportunities and efficiencies for intermediaries, and can do the following:
- Automate capital calls and distributions using smart contracts,
- Simplify audits and ensure reporting accuracy through transparent and immutable transaction records.
- Warranty Management: Luxembourg-based DLT platforms allow clients to swap ownership of baskets of securities between different collateral pools at precise times.
- Tokenization: DLT is used to tokenize various assets, including real estate and luxury goods, by representing them in a tokenized and fractionalized format on the blockchain. This process can improve the liquidity and accessibility of traditionally illiquid assets.
- Tokenization of investment funds: DLT is being explored for the tokenization of investment funds, which can streamline the supply chain, reduce costs, and enable faster transactions. DLT can automate various elements of the supply chain, reducing the need for reconciliations between entities such as custodians, administrators, and investment managers.
- Issuance, settlement and payment platforms:Market participants are developing trusted networks using DLT technology to serve as a single source of shared truth among participants in financial instrument investment ecosystems.
- Legal framework: Luxembourg has adapted its legal framework to accommodate DLT, recognising the validity and enforceability of DLT-based financial instruments. This includes the following:
- Allow the use of DLT for the issuance of dematerialized securities,
- Recognize DLT for the circulation of securities,
- Enabling financial collateral arrangements on DLT financial instruments.
- Regulatory compliance: DLT can improve transparency in fund share ownership and regulatory compliance, providing fund managers with new opportunities for liquidity management and operational efficiency.
- Financial inclusion: By leveraging DLT, Luxembourg aims to promote greater financial inclusion and participation, potentially creating a more diverse and resilient financial system.
- Governance and ethics:The implementation of DLT can promote higher standards of governance and ethics, contributing to a more sustainable and responsible financial sector.
Luxembourg’s approach to DLT in finance and fund management is characterised by a principle of technology neutrality, recognising that innovative processes and technologies can contribute to improving financial services. This is exemplified by its commitment to creating a compatible legal and regulatory framework.
Short story
Luxembourg has already enacted three major blockchain-related laws, often referred to as Blockchain I, II and III.
Blockchain Law I (2019): This law, passed on March 1, 2019, was one of the first in the EU to recognize blockchain as equivalent to traditional transactions. It allowed the use of DLT for account registration, transfer, and materialization of securities.
Blockchain Law II (2021): Enacted on 22 January 2021, this law strengthened the Luxembourg legal framework on dematerialised securities. It recognised the possibility of using secure electronic registration mechanisms to issue such securities and expanded access for all credit institutions and investment firms.
Blockchain Act III (2023): Also known as Bill 8055, this is the most recent law in the blockchain field and was passed on March 14, 2023. This law has integrated the Luxembourg DLT framework in the following way:
- Update of the Act of 5 August 2005 on provisions relating to financial collateral to enable the use of electronic DLT as collateral on financial instruments registered in securities accounts,
- Implementation of EU Regulation 2022/858 on a pilot scheme for DLT-based market infrastructures (DLT Pilot Regulation),
- Redefining the notion of financial instruments in Law of 5 April 1993 on the financial sector and the Law of 30 May 2018 on financial instruments markets to align with the corresponding European regulations, including MiFID.
The Blockchain III Act strengthened the collateral rules for digital assets and aimed to increase legal certainty by allowing securities accounts on DLT to be pledged, while maintaining the efficient system of the 2005 Act on Financial Collateral Arrangements.
With the Blockchain IV bill, Luxembourg will build on the foundations laid by previous Blockchain laws and aims to consolidate Luxembourg’s position as a leading hub for financial innovation in Europe.
Blockchain Bill IV
The key provisions of the Blockchain IV bill include the following:
- Expanded scope: The bill expands the Luxembourg DLT legal framework to include equity securities in addition to debt securities. This expansion will allow the fund industry and transfer agents to use DLT to manage registers of shares and units, as well as to process fund shares.
- New role of the control agent: The bill introduces the role of a control agent as an alternative to the central account custodian for the issuance of dematerialised securities via DLT. This control agent can be an EU investment firm or a credit institution chosen by the issuer. This new role does not replace the current central account custodian, but, like all other roles, it must be notified to the Commission de Surveillance du Secteur Financier (CSSF), which is designated as the competent supervisory authority. The notification must be submitted two months after the control agent starts its activities.
- Responsibilities of the control agent: The control agent will manage the securities issuance account, verify the consistency between the securities issued and those registered on the DLT network, and supervise the chain of custody of the securities at the account holder and investor level.
- Simplified payment processesThe bill allows issuers to meet payment obligations under securities (such as interest, dividends or repayments) as soon as they have paid the relevant amounts to the paying agent, settlement agent or central account custodian.
- Simplified issuance and reconciliationThe bill simplifies the process of issuing, holding and reconciling dematerialized securities through DLT, eliminating the need for a central custodian to have a second level of custody and allowing securities to be credited directly to the accounts of investors or their delegates.
- Smart Contract Integration:The new processes can be executed using smart contracts with the assistance of the control agent, potentially increasing efficiency and reducing intermediation.
These changes are expected to bring several benefits to the Luxembourg financial sector, including:
- Fund Operations: Greater efficiency and reduced costs by leveraging DLT for the issuance and transfer of fund shares.
- Financial transactions: Greater transparency and security.
- Transparency of the regulatory environment: Increased attractiveness and competitiveness of the Luxembourg financial centre through greater legal clarity and flexibility for issuers and investors using DLT.
- Smart Contracts: Potential for automation of contractual terms, reduction of intermediaries and improvement of transaction traceability through smart contracts.
Blockchain Bill IV is part of Luxembourg’s ongoing strategy to develop a strong digital ecosystem as part of its economy and maintain its status as a leading hub for financial innovation. Luxembourg is positioning itself at the forefront of Europe’s growing digital financial landscape by constantly updating its regulatory framework.
Local regulations, such as Luxembourg law, complement European regulations by providing a more specific legal framework, adapted to local specificities. These local laws, together with European initiatives, aim to improve both the use and the security of projects involving new technologies. They help establish clear standards and promote consumer trust, while promoting innovation and ensuring better protection against potential risks associated with these emerging technologies.
