Bitcoin was the first decentralized cryptocurrency. Since then, it has experienced massive growth. It was created in 2009.

My research is supported by NSF (including an NSF CAREER award), NSA, DHS, CCI and faculty research awards from Google, Facebook and IBM.

But these crypto tax tools are undoubtedly extremely expensive and out of reach to most nations. And if they can’t tax it, governments are never going to let Bitcoin into their economies willingly.

Yes, as a data structure a blockchain is similar to a linked list (but it refers to the previous block using its hash rather than using a pointer, thus strictly speaking it is not a linked list). But a blokchain is not so much a data structure as it is a protocol for arriving to a consensus in a decentralized environment. A blockchain isn't a blockchain without rules which describe how nodes validate blocks, select the best chain etc. )を採用せずにハッシュ値を使っているという点で異なるため厳密にはlinked listとして定義されない。加えてブロックチェーンは分散環境のコンセンサスに到達するためのプロトコルであるため、(linked listと違って)データ構造とは言えない。ブロックチェーンは各ブロックを検証するための規定なしではブロックチェーンとしてなり得ない。 (「ブロックチェーンは結局linked listのことをさしているのか」という質問に対して)データ構造としてはlinked listと似ているがブロックチェーンではlinked listでいうポインター( lst1 = [lst0[len(lst0)-1], 1, 2, 3, lst2[0].image
