Cluster: Blockchain and cryptocurrency

A cluster of topics related to blockchain and cryptocurrency.

Base layer protocols

Base layer protocols are the peer-to-peer networks which form the basis of the Decentralized application (dApp) web. These base protocols are typically blockchains with an associated cryptocurrency coin secured by a consensus protocol where participants in the network decide collectively on the addition of new blocks to the blockchain ledger.

Blockchain Theory & Fundamentals

Fundamental concepts related to blockchains.

Blockchain properties

Properties of blockchains and cryptocurrency systems.

Components

Components of blockchains.

Consensus

Consensus algorithms, sybil control mechanisms, and other topics related to consensus mechanisms for establishing a consistent canonical agreement between network participants on the blockchain state.

Sybil control mechanisms

Consensus mechanisms

Blockchain attack vectors

Methods by which malicious actors can attempt to subvert or disrupt the intended functionality of blockchain protocols.

Cryptocurrencies

Cryptocurrencies with the primary intention of a decentralized currency replacement to traditional fiat currencies by being a store of value, a unit of account, or a medium of exchange.

Smart contract platforms

Platforms for decentralized applications allowing for the execution of code on the blockchain in the form of smart contracts. These platforms allow for more generalized logic to be coded on the blockchain enabling a broad range of web 3.0 decentralized applications.

Privacy cryptocurrencies

A specialized form of cryptocurrencies focused on maintaining the privacy and anonymity of individuals transaction with them.

Distributed ledgers (non blockchain)

A class of distributed ledgers whose structure does not rely blocks of transactions but rather other architectures like a directed acyclic graph. These alternate ledgers have different security, scalability, and consensus properties from blockchain technologies.

Permissioned ledgers and blockchains

Blockchains or distributed ledgers that require special access or permission to participate rather than being open to the public.

Infrastructure

Infrastructure comprises the development stack for building decentralized applications. These are protocols and tools that may connect and support applications and other protocols in a variety of ways.

Interoperability

Interoperability protocols allow for communication of state, data, or value transfer between different blockchains.

Decentralized file storage

Store and retrieve files and data without relying on a trusted central authority.

Database

Decentralized database projects.

Scalability

Projects focusing on both on-chain and off-chain solutions for increasing blockchain transaction throughput.

Privacy and security

Privacy and security projects for decentralized applications.

Smart contract developer tools

Tools which help developers create and secure smart contract code.

Smart contract programming languages

Programming languages that are specific to smart contracts i.e. contract-oriented programming languages.

Blockchain oracles and prediction markets

Blockchain oracles are a blockchain technology that allows blockchains or smart contracts to interact with external data sources. Prediction market blockchains focus on bringing traditional prediction markets to the blockchain.

Governance

Projects restructuring the way that institutions, political systems, and people govern and organize themselves using blockchain or decentralized technologies.

Decentralized organizations

Projects with decentralized governance or providing support for managing organizations through decentralized governance.

Legal

Connecting decentralized systems into traditional legal frameworks.

Open Internet

Projects working towards a more open and user controlled Internet.

VPN

Decentralized VPN services.

Value Exchange

Projects creating marketplaces or frameworks for peer to peer value exchange without a centralized intermediary. Projects in these categories often have what are considered utility tokens, which represent future access to a service.

Advertising

Advertising platforms connecting users, advertisers, and publishers directly without ad network intermediaries.

Data

Protocols enabling the sharing and monetization of data resources.

Decentralized marketplaces

Projects building decentralized marketplaces.

Decentralized mesh networking

Projects working on decentralized mesh networks.

Social

Decentralized social networks, communication tools, and social related applications built using blockchain technology. These projects employ a variety of differentiators from traditional social networks involving data privacy, monetary incentives, and more.

Content Monetization

Projects working on decentralized content monetization platforms enabling content creators and content consumers to transaction directly without third party mediation.

Computation

Decentralized projects in which users provide computation in exchange for tokens.

Energy

Projects focusing on the redistribution, transmission, and retail of energy via decentralized systems.

Property & housing rental

Decentralized property and housing rental.

Rides

Decentralized ride sharing.

Genome

Projects related to decentralized storage of genomic data and marketplaces for the exchange of genetic information.

Financial

The field of decentralized finance and cryptocurrency investments.

Centralized exchanges

Centralized exchanges for cryptocurrencies trading.

Decentralized Exchanges (DEX) or non-custodial relayers

A decentralized cryptocurrency exchange is an exchange market that utilizes blockchain or another decentralized technology to enable peer to peer transfer of digital assets without reliance on a trusted third party to hold funds usually supported by liquidity providers.

Payments

Services that help individuals make payments.

Trading / market makers

Tools and projects assisting the trading and exchange between cryptocurrencies.

Asset management platforms

Escrow
Tax platforms
Crypto hedge funds

Cryptocurrency hedge funds are investment funds which pool capital from investors into a group of assets focusing entirely or partially on cryptocurrencies or other decentralized digital assets.

Credit & lending

Projects working on credit, risk, and lending.

Insurance

Decentralized peer to peer insurance.

Security Tokens

Platforms for issuing and exchanging tokenized securities.

Debit Cards

Debit cards for spending cryptocurrencies.

Crowdfunding

Platforms to manage and launch blockchain crowdfunding projects.

Stablecoins

Stablecoins are projects attempting to create decentralized cryptocurrencies with specific properties like low volatility and non reliance on centralized backing.

Liquidity & accessibility
Crypto-collectibles

Crypto-collectibles are digital collectibles, commonly using the ERC-721 non-fungible Ethereum token standard, recorded on a blockchain ledger.

Other

Other types of cryptocurrency and blockchain related projects.

Data authenticity and supply chain

Securing data records on immutable ledger systems.

Consulting
