HashTower 與開發心得 2023-03-21
Background
membership
Map
Merkle Tree
Incremental Binary Tree
RSA Accumulator
gas
HashTower
Amortized cost: O(1)
one-way hash function: 固定 / 瞄準 / ZK
idea
video
不要被 tree 限制想像
觀察變化的 pattern / 觀察操作的 pattern
Incremental hash (homomorphic hash)
Lazy
用 circuit complexity 換 gas
Circom
光看 document 不夠
Release Note
Paper
channels
iden3
PSE
ZeroKnowledgePodcast
ZK bug tracker
(Search: under constrained bug)
運用新的 anonymous component syntax
用 zkrepl
用 circom tester
IsZero 和 a === 0
除法的例子
"證明"
兩個程式寫在同一個程式裡
所有 signal 都是 "input"
Javascript
用 Javascript 先 prototyping circuit 和 contract (高階)
用 Javascript 來驅動測試, 同時也測到 Javascript
用簡單的測複雜的, 用複雜的測更複雜的
Solidity
了解 gas cost
Hash
SSTORE
SLOAD
public signal
dynamic array
其他
和 Semaphore 學習
