About P2P.Systems

P2P.Systems was co-established in July 2017 by Adam Kotucha, Jacek Sieradzki, Tomasz Korwin-Gajkowski, Tomasz Kurowski, and Wojciech Kwiatek as a General Partnership. Our initial co-operation commenced in early 2017 while working on the project of organizing the very first blockchain meetups in Krakow – Crypto@Cracow. With the passage of time, the idea has became one of the most attended Krakow’s technology speaker-series event. Based on these experiences, our p2p.systems team of professionals with a mixed area of expertise has been born.

Blockchain FAQ

We realize that knowledge is power, that is why, we have prepared a short jargon glossary to introduce you to the world of blockchain.

What is blockchain?

Blockchain – is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. A blockchain can serve as an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. The blockchains can be either public (bitcoin) or private (enterprise).

What is a cryptocurrency?

Cryptocurrency is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency. Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies. The very first cryptocurrency was bitcoin, the others are often called as altcoins.

What is bitcoin?

Bitcoin is a worldwide cryptocurrency and digital payment system called the first decentralized digital currency, as the system works without a central repository or single administrator, It was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009. The system is peer-to-peer, and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain.

What is a smart contract?

A smart contract is a computer protocol intended to facilitate, verify, or enforce the negotiation or performance of a contract. Smart contracts were first proposed by Nick Szabo in 1996. Proponents of smart contracts claim that many kinds of contractual clauses may be made partially or fully self-executing, self-enforcing, or both. The aim with smart contracts is to provide security that is superior to traditional contract law and to reduce other transaction costs associated with contracting.

What is a distributed ledger?

A distributed ledger (DLT) is a consensus of replicated, shared, and synchronized digital data geographically spread across multiple sites, countries, or institutions. There is no central administrator or centralized data storage. A P2P network is required as well as consensus algorithms to ensure replication across nodes is undertaken. One form of distributed ledger design is the blockchain system, which can be either public or private. But not all distributed ledgers have to necessarily employ a chain of blocks to successfully provide secure and valid achievement of distributed consensus: a Blockchain is only one type of data structure considered to be a distributed ledger.
