O modalitate de venit pasiv"},"content":{"rendered":"

S-ar putea s\u0103 sune ca un termen complicat, dar nu este mare lucru odat\u0103 ce \u00eel prime\u0219ti \u0219i \u00eel pui \u00een practic\u0103, chiar. Pentru a fi rapid: Proof of Stake (PoS) este un tip de sistem digital (algoritm) pentru a ob\u021bine consensul \u00eentr-un blockchain,<\/strong> ceea ce \u00eenseamn\u0103 s\u0103 verifica\u021bi tranzac\u021biile \u0219i s\u0103 bate\u021bi monede noi. \u0218i da, poate fi \u0219i o modalitate de venit pasiv, pentru oricine are suficiente fonduri la \u00eendem\u00e2n\u0103.<\/p>\n\n\n\n

Deci ... este ceva ca minarea criptomonedelor? Un fel de. Este practic o alternativ\u0103 pentru tradi\u021bionala exploatare a criptomonedelor Proof of Work (PoW), care este utilizat\u0103 de monede precum Bitcoin (BTC). S\u0103 ne amintim pu\u021bin.<\/p>\n\n\n\n

PoW este un alt algoritm<\/a>, \u0219i prin \u201ealgoritm\u201d \u00een\u021belegem un set de pa\u0219i \u0219i metode care sunt construite - cu matematic\u0103 - pentru a ob\u021bine un rezultat specific sau a rezolva o problem\u0103. Exact asta face PoW: dezvolta o problem\u0103 matematic\u0103 dificil\u0103 sau o ghicitoare pe care echipamentul minerului trebuie s\u0103 o rezolve pentru a verifica tranzac\u021biile virtuale. Vor c\u00e2\u0219tiga apoi ni\u0219te criptomonede ca recompens\u0103 pentru serviciile lor.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Acest miner va avea nevoie de hardware puternic, o anumit\u0103 cantitate de cuno\u0219tin\u021be tehnice \u0219i mult\u0103 energie electric\u0103 pentru a reu\u0219i \u00een sarcina lor. Acum in Sisteme PoS<\/a> (\u0219i monede) figura \u201eminerului\u201d este \u00eenlocuit\u0103 cu \u201evalidatorul\u201d. Acest validator, care poate fi oricine dore\u0219te, nu va avea nevoie de mult din asta. In schimb, ceea ce vor face este s\u0103 blocheze \u00eentr-un portofel special o anumit\u0103 cantitate de jetoane native pe care le-au achizi\u021bionat anterior.  <\/strong><\/p>\n\n\n\n

Deci, vor ob\u021bine dreptul de a verifica tranzac\u021biile \u0219i de a bate monede noi, dac\u0103 este necesar, \u0219i aproape automat. \u0218i vor fi recompensa\u021bi pentru asta, ca venit pasiv. Totu\u0219i, asta are dezavantajele sale.<\/p>\n\n\n\n

Ce este \u00een neregul\u0103 cu PoS, atunci?<\/strong><\/h2>\n\n\n\n

R\u0103spunsul scurt pentru aceasta este securitatea furnizat\u0103 re\u021belei. S\u0103 ne oprim pu\u021bin aici pentru a vorbi despre furci. \u0218ti\u021bi, majoritatea criptomonedelor sunt s\u0103lbatice \u0219i f\u0103r\u0103 drepturi de autor, open-source \u0219i descentralizate. Asta inseamna oricine are cuno\u0219tin\u021be poate copia \u0219i lipi propria versiune a aceleia\u0219i criptomonede: aceasta este o furculi\u021b\u0103<\/strong>, deoarece pot \u00eemp\u0103r\u021bi re\u021beaua pentru a o lua \u00een alt\u0103 direc\u021bie.<\/p>\n\n\n\n

Pentru a spune mai clar, Bitcoin Numerar<\/a> (BCH) este, de exemplu, o furc\u0103 de Bitcoin<\/a> (BTC). Au aceea\u0219i istorie p\u00e2n\u0103 \u00een 2017, c\u00e2nd BCH s-a \u00eemp\u0103r\u021bit \u00een alt\u0103 direc\u021bie \u0219i cu noi func\u021bionalit\u0103\u021bi. Dar hei, ambele func\u021bioneaz\u0103 cu PoW, nu cu PoS. Asta \u00eenseamn\u0103 c\u0103 minerii ar fi trebuit s\u0103 decid\u0103 atunci \u00eentre ei doi. Puterea lor de calcul, eforturile lor grele, nu pot fi \u00eemp\u0103rt\u0103\u0219ite cu dou\u0103 lan\u021buri, deoarece ar cheltui dublu aceia\u0219i bani.<\/p>\n\n\n\n

\"Two-Bitcoin-Cash-supravie\u021buitor\"<\/figure>\n\n\n\n

Acesta este de fapt un risc cu sistemele PoS. Cu PoW nu are sens s\u0103 creezi furci nesf\u00e2r\u0219ite, dar \u00een PoS pot fi profitabile pentru \u00een\u0219el\u0103tori. Deci, utilizatorul ar putea s\u0103ri \u00eentre lan\u021bul ini\u021bial unde a cheltuit deja banii \u0219i noul lan\u021b unde nu a f\u0103cut-o<\/strong>, for example.  There\u2019s no \u201cwork\u201d to verify the transactions here, only stakeholders.<\/p>\n\n\n\n

Dezvoltatorii lucreaz\u0103 la aceast\u0103 posibil\u0103 problem\u0103. S-au propus pedepse pentru comportament prost, cum ar fi t\u0103ierea sau confiscarea mizelor \u00een\u0219el\u0103torilor. Totu\u0219i, este o lucrare \u00een desf\u0103\u0219urare. \u0218i sistemele PoW au, de asemenea, unele dezavantaje.<\/p>\n\n\n\n

Deci, ce este \u00een neregul\u0103 cu PoW?<\/strong><\/h2>\n\n\n\n

Probabil c\u0103 principala problem\u0103 care poate ap\u0103rea \u00eengrijor\u0103ri legitime cu privire la acest sistem este factorul de mediu. PoW blockchains<\/a> sunt \u00een mare parte puternice \u0219i sigure, dar costul este energia (electricitatea) cheltuit\u0103 de hardware pentru a rezolva ghicitori matematice (munca).<\/p>\n\n\n\n

Potrivit Cambridge Centre for Alternative Finance (CCAF<\/a>), Bitcoin (de exemplu) are un consum anual estimat de energie de aproximativ 12,65 TWh<\/strong>. Pentru perspectiv\u0103, asta este mai mult dec\u00e2t \u021b\u0103ri precum Finlanda, Elve\u021bia \u0219i Portugalia.<\/p>\n\n\n\n

Luand in considerare<\/a> c\u0103 fiecare 1 KWh produce aproximativ 1 kilogram de dioxid de carbon (CO2) eliberat \u00een atmosfer\u0103 (\u0219i \u00eel polueaz\u0103), ceea ce ar \u00eensemna \u00een jur de 6,4 Mt (milioane de tone) CO2, ca rezultat \u00een fiecare an. Desigur, este mai degrab\u0103 o cifr\u0103 mic\u0103, compar\u00e2nd-o cu alte activit\u0103\u021bi, industrii \u0219i \u021b\u0103ri.<\/p>\n\n\n\n

\"PoS-venit-Bitcoin-energie\"
Bitcoin este cu mult \u00een urma celor mai mari consumatori de energie din lume. Sursa: CCAF<\/figcaption><\/figure>\n\n\n\n

Industria bancar\u0103 produce anual aproximativ 319,5 Mt CO2. Exploatarea aurului produce 69,4 Mt CO2, Statele Unite 1.951 Mt CO2 \u0219i China 2.782 Mt CO2. Dincolo de aceasta, a\u0219a cum a indicat \u0219i CCAF, Bitcoin ia abia 0.49% din consumul total de energie.<\/strong><\/p>\n\n\n\n

\u00cen plus, un studiu realizat de firm\u0103 CoinShares<\/a> a dezv\u0103luit c\u0103 cripto-minerii obi\u0219nuiesc s\u0103 se stabileasc\u0103 \u00een locuri \u00een care energia electric\u0103 este mai ieftin\u0103, pentru a ob\u021bine mai multe profituri. \u0218i electricitatea mai ieftin\u0103 \u00eenseamn\u0103, de obicei, surse de energie regenerabile (\u0219i nepoluante), cum ar fi hidroelectricitatea. Deci, aceast\u0103 chestiune este \u00eenc\u0103 \u00een discu\u021bie.<\/p>\n\n\n\n

Monedele PoS ca venit pasiv<\/strong><\/h2>\n\n\n\n

L\u0103s\u00e2nd deoparte ce sistem este mai bun (un r\u0103spuns nu este stabilit \u00eenc\u0103, oricum), ceva sigur este c\u0103 oamenii pot ob\u021bine c\u00e2\u0219tiguri pasive doar \u021bin\u00e2nd monede PoS \u00een portofele lor.<\/strong> Cu c\u00e2t ave\u021bi mai mult \u0219i cu c\u00e2t ave\u021bi mai mult timp blocat (neutilizat), cu at\u00e2t pute\u021bi ob\u021bine mai multe c\u00e2\u0219tiguri (\u00een aceea\u0219i moned\u0103).<\/p>\n\n\n\n

V\u0103 pute\u021bi g\u00e2ndi la asta ca la ceva similar cu conturile de economii, dar probabil cu mai multe interese. \u0218i, ar trebui s\u0103 spunem, cu probabil \u0219i mai mul\u021bi bani \u00een joc. A deveni validator PoS nu este ieftin, precis. Asta pentru c\u0103 principiul principal din spatele acestui sistem este c\u0103 utilizatorii lor ar trebui s\u0103 fie cu adev\u0103rat interesa\u021bi de bun\u0103starea re\u021belei.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Putem folosi c\u00e2teva exemple aici. Recent, Ethereum lansat<\/a> primul s\u0103u sistem PoS. Pentru a deveni un viitor validator al acestuia, utilizatorii trebuie s\u0103 fi blocat 32 ETH (acum aproximativ $41.6k) \u00een portofelul destinat acestuia. Conform calculatorului (experimental) furnizat de Ethereum Pre\u021b<\/a>, acest lucru ar implica aproximativ 8.9% \u00een dob\u00e2nd\u0103 anual\u0103 c\u00e2\u0219tigat\u0103.<\/strong><\/p>\n\n\n\n

Cifrele variaz\u0103 \u00een diferite monede PoS. Dash cere<\/a> o garan\u021bie de 1.000 de jetoane ($105.700) pentru validatorii s\u0103i PoS \u0219i ofer\u0103 aproximativ 6% dob\u00e2nd\u0103 anual\u0103. Pe de alt\u0103 parte, \u00een Cosmos (ATOM)<\/a> exist\u0103 diferite niveluri pentru miza. Primul nu necesit\u0103 o sum\u0103 specific\u0103 ca minim pentru a miza, o pute\u021bi face cu u\u0219urin\u021b\u0103 din portofele de genul Portofel atomic<\/a>, iar profitul calculat este de 8% anual. Nivelul urm\u0103tor (pentru validatorii oficiali) este totu\u0219i mai greu de atins. Costurile<\/a> sunt peste $57k.<\/p>\n\n\n\n

In concluzie? Monedele PoS pot face un venit pasiv foarte frumos, dar nu f\u0103r\u0103 o investi\u021bie pl\u0103cut\u0103.<\/strong> Oricum, \u00een cazul \u00een care sunte\u021bi interesat, aici pute\u021bi g\u0103si un lista monedelor PoS<\/a> a ridica. Dar nu uita\u021bi s\u0103 v\u0103 face\u021bi propriile cercet\u0103ri (DYOR<\/a>) mai \u00eent\u00e2i!<\/p>\n\n\n\n
