What are the limits of Bitcoin?
Bitcoin is a P2P network and, as such, faces limitations inherent to the underlying networks as well as the limitations of its own protocol. In this article we take a look at the ...
Estimating Cardano ADA Staking Rewards
July 2020 Update
Cardano has finally released the Shelley mainnet. From this point forward, staking rewards will no longer be estimated. Once epoch 210 is concluded, we'll have...
ELI5: What is BetterHash?
BetterHash is a cryptocurrency mining method developed by Bitcoin Core developer Matt Corallo.
The main idea behind BetterHash is to improve decentralization of Bitcoin mining ...
ELI5 Cryptocurrency Sharding
If you come from the world of IT, then you've probably heard of database or disk data sharding.
For those who don't come from IT, a real simple way to put it is that sharding m...
Understand the basics of smart contracts
What's a smart contract? What makes it smart? How can I deploy my own contracts on the Ethereum blockchain? In this article we explore these questions and give you an overview abo...
Proof of Elapsed Time (POET) Summary [Cryptocurrency consensus mechanisms]
In this poetically named consensus mechanism, network participants prove that they have slept for a random amount of time before being able to mint a block. POET was released by Intel in 2016 and was originally aimed at trusted computing using Intel CPU’s. A special instruction set called Software Guard Extensions (SGX) allows programs to […]
ELI5: Blockchains explained in simple terms
A blockchain is a database formed by a sequence of entries called (you guessed it) blocks. Blockchains have a special characteristic by which any attempt to modify one of its entries would modify the entire chain. It is, therefore, an immutable data structure, which stores blocks in chronological order of insertion. This makes blockchain a […]
Proof of Location (PoL) Summary [Cryptocurrency consensus mechanisms]
In a Proof of Location consensus algorithm, users’ geospatial coordinates are accounted for as proof of value. This kind of algorithm is usually employed in cryptocurrency geomining systems. In a geomining application, users earn rewards for being at a certain place at a certain time. If, for example, a company wished to gather participants for […]
ELI5 Proof of Stake (PoS) – How does PoS work?
In the cryptocurrency universe, Proof of Stake (PoS) is one of the most popular alternatives to the Proof of Work (PoW) family of consensus mechanisms. While PoW systems invest large amounts of energy to make sure transactions are legit, PoS does not require mining hardware. Proof of Stake “miners” (stakers) must lock a financial stake […]
Concepts In This Page
A process or system by which multiple parties are able to reach consensus. In the context of cryptocurrencies, it's the process which allows for everyone to agree on everyone else's money balance. E.g. Bitcoin employs Nakamoto consensus via PoW mining.
Ethereum Virtual Machine (EVM)
The Ethereum Virtual Machine (EVM) is the individual component which enables the worldwide decentralized computing infrastructure on the blockchain. Smart contracts actually run on each individual EVM instance around the world. Miners verify and store results from EVM computing processes on the blockchain.
The fundamental data structure which powers distributed ledger technology (DLT). Bitcoin implemented the first successful cryptocurrency using a blockchain for its ledger storage system.
A Cryptocurrency Ecosystem refers to the technologies and community around one or more cryptocurrency projects. Cryptocurrencies are naturally peer-to-peer systems which depend on active communities in order to thrive. An ecosystem is formed by the communities which use, drive value and further develop the technology.
