Public -Private - Permissioned

Public blockchains allow anyone to access them; private blockchains are closed to only selected users; permissioned blockchains are a hybrid of public and private blockchains where anyone can access them as long as they have permission from the administrators to do so.
Public Blockchain.

A public blockchain is decentralized, permissionless, and self-governed by its members. Anyone is free to join and participate in the core activities of the blockchain network. A public network operates on an incentivizing scheme that encourages new participants to join and keep the network agile. Public blockchains offer a particularly valuable solution from the point of view of a truly decentralized, democratized, and authority-free operation.

Private Blockchain.

A private blockchain is not decentralized as it operates within a closed network with an operator. Only selected and verified participants are allowed access; the operator has the right to override, edit, or delete entries on the blockchain. Only authorized users can run a full node, make transactions, or validate/authenticate blockchain changes. Private blockchains are less focused on protecting user identities and more on promoting transparency, thereby prioritizing efficiency and immutability within private internal networks. These are important features in supply, logistics, payroll, finances, accounting, and many other enterprise and business areas.

Permissioned Blockchain.

A permissioned blockchain uses elements of both public and private blockchains. Anyone is allowed to join the network (after having their identity verified), but only designated members are granted permission for specific activities on the network. This allows certain members to carry out particular functions such as accessing or entering data on the blockchain. Permissioned blockchains are particularly useful for businesses looking to adopt blockchain technology for their services, designed in a scalable manner, where the providers cater to the needs of other members or companies that they rent access out to.

Decentralized applications (dApps) are apps that function autonomously through decentralized computing, blockchain or distributed ledger systems and typically use smart contracts. They operate without human intervention and without the control of a central authority. dApps are inherently trustless and transparent and utilized for DeFi systems.

Decentralized applications (dApps) are digital applications that run on the blockchain or peer-to-peer (P2P) computer networks allowing them to operate entirely outside the scope of a single authority. dApps are used for a broad variety of purposes, including gaming, finance, and social media, to name a few.

Standard web apps are built on central computer systems that are privately operated by an organization or company with absolute authority over the app, its workings, and all the data it collects from its users. Users are subject to moderation, suppression, and even removal by those who control the application.

dApps, on the other hand, run on a decentralized network where all its users are participants contributing to the operational functionality of the system, simultaneously consuming, feeding and/or seeding content. Applications that use P2P or blockchain networks operate in a public, open source, decentralized environment free from control or interference by a central authority.




A token, also known as a cryptographic token, represents a tradable digital asset or utility such as access rights. Tokens are stored securely through cryptography on existing blockchains and are usually managed by smart contracts. They grant permission and/or ownership to a user. Tokens have a wide range of potential functions and applications and represent much more than only cryptocurrencies, which are just one form of tokens. Other types of tokens include security tokens and utility tokens, to name a few.

Tokens are digital assets developed on top of existing blockchain networks. They can be used for a huge range of applications and come in different forms that can be classified as either digital assets, access rights or both (hybrid). They can be used for a multitude of functions, from participating in DeFi mechanisms, proving ownership over data, software licenses, verifying memberships, accessing subscriptions, playing games, to granting voting permissions, and much more. Tokens play a big part in how blockchain technology works.

Cryptocurrencies are a form of tokens; however, tokens are more than just cryptocurrencies. Other forms of tokens are security tokens, utility tokens, and DeFi tokens. Governance tokens, Non-Fungible Tokens (NFTs), and many more! The uses of these digital assets are endless, and they can be developed for any number of purposes and integrated in many different ways. The bottom line is that because tokens are based on blockchain technology, they use advanced encryption techniques which assure their authenticity and eliminate the risk of counterfeiting, making extremely reliable and secure digital assets.

At Ledger Leopard, we can help you develop and integrate custom tokens for blockchain-enabled solutions. Our token offering services is a one-stop-shop for launching a token offering for your business! We provide end-to-end development to create your very own token, build you a platform, provide consulting services and management support, and much more!

Legally Verified Identity - KYC- SSI

Digital identity verification plays a vital role in today’s digital world. It’s the process whereby individuals’ personal information is checked to authenticate their identity to access and use digital services. This is not only important for individual users to safeguard them against scams and identity theft, but it’s also crucial for businesses operating online to be able to identify their customers and protect them from cybercrime and fraud. Read on to find out more about the main digital identity verification systems, KYC and SSI.

Legally Verified Identity

Increasingly, individuals and businesses rely on digital infrastructure for services. The need for online identity verification is therefore more important than ever, not only for individual users but also for businesses operating online. Through identity verification, businesses can ensure their user base is genuine and have secure communication with particular clients allowing them to conduct business together. It helps combat fraud, money laundering, eliminates potential fake customer identities, and plays an important role in many institutions - especially financial ones. Furthermore, identity verification is required by law and supported by legal frameworks in most places in the world. Identity verification was initially carried out physically, in a face-to-face context with individuals proving their identity by presenting personal documents. Nowadays, the identification procedure is increasingly conducted online, making it a safer, quicker, and more convenient process allowing thousands of companies and clients to interact successfully with each other. As digital identity verification methods improve, using new technologies like secure AI systems, so does your data privacy and the safety of the data you upload online. These verification methods are compliant with regulations and must foster trust in clients as well as a positive user experience to be truly effective. If identity verification is overly complicated and time consuming, users will dread using them. This is why the best solutions are easy-to-use, fast-operating processes and intuitive procedures.


The standard in financial services is KYC (Know Your Customer/Client), designed to protect financial institutions against fraud, corruption, money laundering, and illicit financing activities such as terrorist financing. KYC protocols involve several steps to establish and verify customers’ identities, determine the nature of customers’ activities and check that the source of funds is legitimate, and assess money laundering risks associated with the clients. Checks are conducted for red flags related to the client: whether the client is known on a sanctions list or is politically engaged, for example. These protocols protect both the client and the financial institution, such as an investment firm. The investment industry uses KYC protocols because it provides investment advisers with detailed information on their clients’ risk tolerance, investment knowledge, and financial position. KYC compliance typically involves requirements and policies such as risk management, customer acceptance policies, and transaction monitoring. Minimum KYC requirements were established by the Financial Crimes Enforcement Agency (FinCEN) for verifying beneficial owners and establishing guidelines for dealing with third parties. The SEC also requires new customers of financial services to provide detailed financial information compliant with KYC guidelines before they can open an account for digital financial services.


Blockchain technology offers a refreshing alternative to the conventional identity models, namely the Self-Sovereign Identity (SSI) model. SSI is a blockchain-based system that doesn’t require an intermediary identity provider and allows users to access and store their own identity data. It takes big tech out of the equation entirely and grants users data privacy and control over their own digital identity.

Blockchain Wallets

In order to interact with blockchain networks and to securely store, manage, and trade tokens such as security tokens, NFTs and cryptocurrencies users utilize a digital wallet. There are various different kinds of digital wallets, such as Open Source Wallets, Trust Wallets, SSI Wallets, and Multi-Sig Wallets. Find out more about the different kinds of wallets and what they can offer.

Open Source Wallet

The biggest appeal of open source wallets is that their code can be reviewed and publicly audited for potential security issues. As a result, open-source software is often more robust than closed-source. The same goes for crypto wallets. These wallets can operate on different platforms/OS systems supporting a variety of features.

Trust Wallet

A Trust Wallet is a specific type of decentralized digital wallet that uses strict KYC processes to verify the validity of users’ credentials, whether they are natural persons or legal entities. Trust wallets become more and more a mandatory requirement when used for asset transactions based on tokens. A trust wallet will allow the government to implement a proper governance process leveraging existing laws and legislation.

SSI Wallet

SSI wallets are digital wallets that use self-sovereign identity (SSI) protocols to store your personal verifiable credentials in a private, secure, and easily accessible manner. These wallets are based on W3C (World Wide Web Consortium) standards and allow users to self-manage their credentials with a high degree of interoperability. SSI can also be used in combination with token solutions, authentication solutions, smart contract solutions, and metadata storage supporting peer-to-peer transactions.

Multi Sig Wallet

Multisignature (Multi Sig) wallets are a highly secure token storage option for groups or organizations that are looking to administer funds in trustless environments whereby multiple parties are involved that may not know each other. Most wallets are operated with a single private key to authorize transactions, Multi Sig wallets, however, require two or more private keys to sign off on a transaction. This allows for the management of assets of a team or organization in a more secure manner, as no individual party has the authority to access the assets.

Smart contracts - NFTS

Smart Contracts.

Smart contracts are fundamental to the effectiveness and efficiency of Web3. They are digital contracts stored on a blockchain that is automatically executed when predetermined terms and conditions are met. They are typically used to automate the execution of an agreement so that all participants can be immediately certain of the outcome without any intermediary’s involvement or time loss. They can also automate a workflow, triggering the next action when conditions are met.

Think of a smart contract as a program that allows two parties to make an immediate exchange without an intermediary or time lag. Using smart contracts, you could transfer funds, register a vehicle, send a notification or issue a ticket without any hassle. When this happens, the blockchain is automatically updated, registering and finalizing the transaction all at once. A completed transaction cannot be reversed or undone and can only be viewed by the involved parties.

Within a smart contract, there can be as many stipulations as needed in order to guarantee that the task is completed according to the satisfaction of the participants. These terms are set by participants when they agree on how their data is represented on the blockchain, the rules and conditions that govern the transaction, and defining the framework for resolving any issues.

Smart contracts are usually programmed by a developer – although increasingly, organizations with blockchain integrations provide templates, web interfaces, and other online tools to simplify the process.

Non-Fungible Tokens (NFTs)

NFTs are singular and non-reproducible cryptographic tokens registered to a unique identification code on the blockchain. They are essentially digital assets like artworks, licenses, or media files that come paired with a digital proof of ownership and public certificate of authenticity that can be bought, sold, and traded. Think of NFTs as a one-of-a-kind piece of digital property, unlike cryptocurrencies that are interchangeable with other tokens of the same type and value.
