Transforming Blockchain for a Climate Neutral World

Where a bank or provider used to serve as an inter­me­di­ary, there is now a more decen­tralised method for trans­ac­tions: The blockchain. Behind it is a dig­i­tal process that allows you to store and for­ward mon­ey, infor­ma­tion or oth­er things that can be record­ed in data. Sen­si­tive data is han­dled with a high lev­el of secu­ri­ty. Find out how a blockchain works and how Ecrop uses it in an envi­ron­men­tal­ly friend­ly way here.


How does a Blockchain work?

Think of blockchain as a kind of mod­ern account­ing. The data to be record­ed is stored in dig­i­tal blocks that are linked togeth­er to form a chain. Data stored in a block gen­er­ates a so-called ​“hash” for the block. This is a dig­i­tal fin­ger­print con­sist­ing of a com­bi­na­tion of let­ters and num­bers. Like a fin­ger­print, each hash is unique. You can recog­nise from it which block it is and which data is record­ed in it. If a new block with new data is cre­at­ed, it receives the hash of its pre­de­ces­sor in addi­tion to its own hash. The two are now linked and a chain is cre­at­ed.

How is the data in the blockchain secured?

If some­one were to try to manip­u­late the data in a block, the hash of the block would change along with the data. The sub­se­quent blocks would then be invalid because they do not have the new hash. To pre­vent a fast com­put­er from sim­ply recal­cu­lat­ing the invalid hash, there is the ​“proof-of-work” mech­a­nism. The mech­a­nism slows down the pro­duc­tion of new blocks and makes recal­cu­lat­ing all the blocks of the cor­re­spond­ing chain seg­ment too cost­ly. Anoth­er pre­cau­tion­ary mea­sure is the dis­tri­b­u­tion of back­up copies to all par­tic­i­pants rep­re­sent­ed in the net­work. So every­one keeps a decen­tralised record at the same time. Every­one has insight into the blocks of a chain in which they par­tic­i­pate and can con­firm their valid­i­ty and add new blocks. Thus, a demo­c­ra­t­ic con­sen­sus always pre­vails in the blockchain. There is no need for a third par­ty to ver­i­fy the data. The trans­mis­sion of infor­ma­tion is faster and cheap­er.

What is a blockchain used for?

The secure and decen­tralised infra­struc­ture of a blockchain offers numer­ous pos­si­ble appli­ca­tions. The most wide­ly used is the trans­ac­tion of mon­ey in the form of cryp­tocur­ren­cy. You’ve prob­a­bly heard of Bit­coins and Co. If you want to send mon­ey to some­one in this way, the data of the trans­ac­tion — sender, recip­i­ent, amount — is stored on a block and autho­rised via the meth­ods men­tioned. The pro­duc­tion of cryp­tocur­ren­cies or any vari­ant of a cryp­to­val­ue or cryp­toas­set also takes place on the blockchain. Some­times cryp­to assets serve a pur­pose oth­er than just being a means of pay­ment. For exam­ple, they can rep­re­sent your prof­it shares or vot­ing rights. In this case, they are called tokens instead of coins. Blockchains set up specif­i­cal­ly for this pur­pose are respon­si­ble for map­ping and legit­imis­ing your tokens. But blockchain tech­nol­o­gy could also be used to sort patient files, notarise doc­u­ments or organ­ise the count­ing of votes. Any appli­ca­tion is con­ceiv­able that requires data records to be stored trans­par­ent­ly and secure­ly. One catch is that this costs elec­tric­i­ty. Dig­i­tal data­bas­es like a blockchain have to be host­ed by servers and man­aged by com­put­ing sys­tems. The com­put­ers, in turn, prob­a­bly draw their ener­gy from sources that burn coal or gas. This leaves open the ques­tion: How do we make the process of a blockchain cli­mate-friend­ly?
