Blockchain explained Simon Clayton, chief ideas offi cer at RefTech, talks Blockchain: what it is, how it works, and why it’s not great for the exhibition industry A 40 s a concept, Blockchain is actually quite interesting and is known as ‘distributed ledger’ technology. Pretty much everything we do online creates data and Blockchain is a new way of storing and moving that data. Data has to be held somewhere and usually gets stored in clumps in one place – whether that is on a company’s server, your own PC or in the cloud. With Blockchain the data is split into tiny pieces and spread out over thousands of places via a network and then held together with clever cryptography. And that’s one of the problems: the very nature of Blockchain means there is no central controlling power over that data, which may be perfect for the anarchists looking for a way to create a decentralised non- government controlled currency, but not so perfect for your company and your event. Exhibitions are owned/ controlled by one company and so it stands to reason that the organising company wants to have full control over the data they hold. Another issue with the data held in a Blockchain is that it is in the public domain, albeit encrypted. One of the reasons it is being heralded as a completely unalterable and therefore a safe way of holding data is because of the public nature of some of the data – if the chain is added to then the changes are there for everyone to see. Exhibition organisers don’t want their sensitive data – such as the number of tickets they’ve sold – to be fl oating around the internet in a way that’s harder to protect. The third issue is that Blockchain creates an immutable chain of data, so what can you do when the inevitable occurs and the data needs to be changed? Every piece of software has bugs that need to be fi xed, or upgrades that need to յɽ)́ѡЁх́ѽ)1̰ٕ́)ͼ́ѡфݔѽɔ)Q́ͽЁ)ѕ䁑́ٔ)䁅ѥ̰)Ё'e)ЁɐѼ͕)܁ӊé)Ѽ)̸ٕ)ٕ)ѥѥ)́ѡ+Ё)ѡ))չᡥѥ̹լ)ѼͥЁȁ Ѽ$Օ́ѡ) ձ剔Ё́ͅչѕə)ѥ́䁍ɕѥхѥ́ѡЁɔ͕ɔ)Ʌͅѥ́ѡɕɔѥЁѡɔ)ɔ䁽ѡȁ݅́Ѽɕєхѥ́ȁ)չѕəѥѡЁɔȁͥȁȁѡ) Qɔ́ͼե͕䁵ɭЁ)ѥ́ͼѡ䁑ѼɅ͙Ʌͽ݅)-䁥́ ѥЁ͕ѕЁɽ)Ёѡȁݕͥєѡ䁽䁡ٔɽչѕ)͵ٕ́ͥѡeɔЁᅍѱ䁕Ѡ)͡ѕɥѡ̸qeѠAAəɵMͥt)qQȁQՕ͑́Ё͍ٕɕtɔݼ)ѡ-䁑́Ё э́嵕аЁٕ) э́Ё͍܁ݥѠͥѕ́Ս)IЁɕͥѼхЁȁ嵕͔́)ٽѥɔ)5ЁٕЁɝ͕́ɔ$ٔɔѡ)ݥѠѡٕ͕ɥɽ٥ѡȁɕЁٕ)Ёљɵ̸ф́مՅɕ)ЁЁѡٕ́́䁅Ѽ̸]ɔѽѼ)ȁمՅ͕́ɔͅչȁ)䁅ݔչхѡ́݅䁽ѡ )ݽɬͽͥ́ɽ͕̃Lхɥ)ЁȁѼɕ́ȁᅵЁ)ȁѡɅѥͥ́)$eЁѡ䁕ٕ́ѡЁѕ)͕ɔչѕɅ٥͕Ʌͅѥ̰)$ՉЁ$ٕȁݥ ́ѥѼѡ)݅䁽Q4չɱ她ݽɭѕѡ)݅́Ѽѡݽɱѡ́Ёѕ)ͽѡԁЁх͔Ёٕ)܁и)Q ́ɔ她ѼЁЁѼ)ٕѡ쁥ӊéͽѥ͕ɍɽ)Qɔ́ȁѡ́ɽ$ɔѡ)ЁݔٔѼɕȁѡЁѡ́́ɕ͕ɍL)ٕиQݥ䁅͕ٕɅѥ́)䁑ɕЁɕ́ɔ ́́) 䁥Ёȁٕ́ѡ)ոЁЁݥյɥѼѥ)ٕѡȁٕ́䁽䁉ѕ)䁉́ѡȁȁѥѥ́ͥа)Ё͔ԁٔɅѕЁѼȁٕ))%܁啅́ݔݽeЁɔЁ ́)́ͽѡݔЁх͔ݥѡ)Ѽ䁽Ʌͅѥ̰Ёٕȁ܁ȁɕ)ɔи)Mѕݡ䁑́役ѡѡЁ )եѕѼѡᡥѥ
