What blockchain?

"We should think about the blockchain as another class of thing like the Internet — a comprehensive information technology with tiered technical levels and multiple classes of applications for any form of asset registry, inventory, and exchange, including every area of finance, economics, and money; hard assets (physical property, homes, cars); and intangible assets (votes, ideas, reputation, intention, health data, information, etc.). But the blockchain concept is even more; it is a new organizing paradigm for the discovery, valuation, and transfer of all quanta (discrete units) of anything, and potentially for the coordination of all human activity at a much larger scale than has been possible before."

– Melanie Swan, Blockchain: Blueprint for a New Economy

Mikä lohkoketju?

"Lohkoketjuteknologialla tarkoitetaan lyhyesti ilmaistuna menetelmää, jonka avulla toisilleen tuntemattomat tahot voivat yhteisesti tuottaa ja ylläpitää lähestulkoon mitä tahansa tietokantoja täysin hajautetusti. Menetelmä toimii siten, että jokaiselle halukkaalle taholle jaetaan kopio tietokannasta (tai sen osasta) ja kaikki osalliset voivat myös tehdä tietokantaan muutoksia määriteltyjen sääntöjen puitteissa. Eri tahojen kulloinkin tekemät muutokset tallennetaan tietokantaan kootusti tietyin väliajoin yhteen niputettuina paketteina, joita kutsutaan lohkoiksi. Kun uusi lohkoja liitetään alkuperäiseen tietokantaan, muodostuu niistä lohkoketju, eli ajantasainen tietokanta kaikkine muutoksineen."

What are people saying?

“The blockchain technological revolution will have as profound area on every area of business as the Internet itself.”

William Mougayar Ethereum Foundation

“The blockchain can change … well, everything”

Robert D. Boroujerdi Goldman Sachs

“Blockchain technology continues to redefine not only how the exchange sector operates, but the global financial economy as a whole”

Bob Greifeld CEO, Nasdaq

“The Blockchain […] facilitates the establishment of new governance models which are flatter, more transparent and potentially allow for more democratic and participatory decision-making. In my view, one of the key benefits of the blockchain is that it reduces (or even eliminates) the need for an intermediary or a middle-man.”
