cryptocurrency

notes

fallacies of crypto haters
- wrought with fraud so it needs 'regulation'
  - banks are the biggest scamming hucksters around and they facilitate most of financial fraud in the world within 'regulations'
- not decentralized
  - 'people do not want to run their own servers' - moxie marlinspike
    - they will and do; a nakamoto number greater than 1 is still more than the status quo
fallacies of crypto bros
- 'trapped energy'
  - sets lower bound on energy production price beyond the government; thus encourages more production regardless of means
  - wasting compute cycles on hashing random numbers instead of folding proteins, simulating fluid dynamics, SETI etc (need internet connection for blockchain sync); price should not be the primary factor for investing in hard research problems.
cross group discrete logarithm equality proof in zero knowledge for shared secret between two chains with different ec curves. (farcaster)
- sigma protocols are alternative (COMINT)

chia

CHIA_ROOT env variable configuration
- burn if not able to melt
check plots with chia plots check -n 30 -l

- mainnet burn xch1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqm6ks6e8mvy
- sends to puzzle hash 0x000000000000000000000000000000000000000000000000000000000000dead
- testnet burn txch1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqm6ksh7qddh

coin_type is 8444 in BLS HD key path
utxo based (not account based like ethereum)
set env var root with export CHIA_ROOT=/usr/local/chia/mainnet/
offer files for p2p exchange (atomic swaps)
- submarine swap cross chain for btc
- ALL CAT v1 Offers/Coins are INVALID as of 1.5 for vulnerability that allows anyone to claim; replaced by cat v2
  - unable to control amount exploited. puzzle hash, coin amount, parent id are sha256 hashed but not validated. fixed by using shatree to validate.
proof of space and time
bls aggregatable signatures
tail emissions of 0.125 xch per block after 12 years
pooling protocol for self block creation
asic timelords
uses 3 'blockchains' with 1 being a transaction chain of foliage to avoid grinding the canonical trunk chain
compression of plots possible with Hellman Attack by using ram/cpu during plotting/harvesting. (tldr: throws first table away and reverses table 2 as needed)
- 'bit dropping' is actually used approach
GPU compressed plot farming for C7(2gb vram) C8(4gb varm) C9(only if free power)
- GPU plotting from mmx madmax
chialisp
- programmable smart contracts
  - autonomous custody with rate limiting, clawback and configurable settlement periods
chain stats dashboard.chia.net
xch domains
- namesdao nft
  - webpages at SevenCharName.xch.cm and SevenCharName.xch.am
each CAT v2 is worth 1000 mojos. smallest unit is thus 0.001 CAT or one mojo.
tibet swap amm based on uniswap v1
https://github.com/dexie-space/splash for decentralized offer broadcasting

chia wallet send -a 0.000000000001 -m 0.000000000001 -t xch1jhye8dmkhree0zr8t09rlzm9cc82mhuqtp5tlmsj4kuqvs69s2wsl90su4 -e "___SevenCharName.xch:xchYOURxchaddress" --override

https://pawket.app/ for some online chia tools. debugger coming soon…
- implemented ecdh for chia addresses
- ecdh for encrypted messages
https://github.com/trepca/chirp for chia messages
1.43 TB of writes per k32
data layer added in 1.6
- store hash in smart coin. updates are tracked on chain along with mirrors
- http server bundled to download and serve data
  - selectively download layers if inclusion proof is acceptable
- can store key value pairs of json etc
  - works with offer files
- ex of video sharing with datalayer https://github.com/jjldv/ChiaTubi
mojo node sql for block reorg
space farmers pool runs community node
- light farming alternative since flexpool shutdown
xch.events for mempool explorer

blunders

Stably provider scammed with PrimeTrust USDS and wrapper btc redemption disabling
- 0.59 btc in reserved. Required 1btc deposit to withdrawl.
CEO/CSO/Employees flame users on reddit (ex. Windows SSL issue)
Trademark trolling chiaplot (news site)/xchscan(block explorer) with fresh law grad
- the chia plot needed a lawyer for them to buzz off
large premine (promised to not use) is being used(sold) to 'marketing' and 'market makers'
layoff of devs after being told "we have years of runway"
hiring WEF managers and fossils(L. Goldman) for DevRel.
Gatekeeping timelord asics
exploited own vulnerability with catv1/v2 upgrade
stably scam
- chia has better custody tools than custodian. Total lack of DD
misrepresent the plot filter increase and effects it will have on farming k32's
- higher quality proofs will be more likely to win. k33 will provide higher proof quality than k32 given same storage space.
Slow development
- pooling release
- compressed plots
  - announced needing new plot format but still bought drplotter compressed farmer
- node perf (dust storm)
- no blockchain download for years (offer torrent now)
atomic swaps and zkrollups not integrated into client for years

monero

use block > 2,688,888 restore height for faster sync times with view tag support (resend old funds etc)
supports tor with sending tx's and wallets
- tx-proxy for sending transactions
- anonymous-inbound allow inbound transactions
randomx for POW algorithm
- ASIC resistance may not be stable long term
  - advertised asic miners contest specific nonces (horizontal lines on graph of block nonces)
    - potential for social cascading for miners to skip those nonces (making the asics better?)
tail emissions of 0.6 XMR per block
variable block sizes
- potential difficulty/timestamp grinding but at cost
p2pool for distributed block creation
- needs zmq enabled monerod
- bundled with gui in 0.18
- mini side chain for lower hashrate
- xmrvsbeast raffle bonus
ringct
- bulletproofs
- ring signatures to obsurce sender, amount, recipient
  - can still trace 'outputs' if you are the sends (alice bob alice attack) or if network is deanonymized (exchanges/users publish view keys, block reward before if enters txo set, transaction fee correlation)
    - churn to avoid and create noise
stealth addresses
- random 1 time addresses for every transaction
Dandelion++
- transaction broadcast and peer sampling to prevent tracing tx origins
No light/SPV clients
- view tags since v0.18
lockable spends with locked_transfer
churn, fracture and consolidate tools
haveno for p2p order book https://blog.nihilism.network/servers/haveno-client-f2f/index.html
- make haveno-apps && make haveno-desktop-mainnet
- reto simplex https://simplex.chat/contact#/?v=2-4&smp=smp%3A%2F%2FSkIkI6EPd2D63F4xFKfHk7I1UGZVNn6k1QWZ5rcyr6w%3D%40smp9.simplex.im%2FMplYm7uxopKyUOrKqnWySpXQIGxoJWYB%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAs8PcRwnf_-H30yXfwV0MSbka9I_xBeVNr4vKJNoReBw%253D%26srv%3Djssqzccmrcws6bhmn77vgmhfjmhwlyr3u7puw4erkyoosywgl67slqqd.onion&data=%7B%22type%22%3A%22group%22%2C%22groupLinkId%22%3A%22YT2t__GnjpZ1W2MjJAz6Sw%3D%3D%22%7D

bitcoin

reuse of ECDSA signatures can lead to key compromise (polynonce attack). use deterministic dsa instead (eddsa or RFC 6979)
double sha256
fixed block size
fixed supply ~21m
lightning
- hash time locked contacts
  - moving to point time locked contracts
- rebalance incoming/outgoing channels for sending/receiving/routing
- preimage based
- watchtowers
  - monitor channel transactions and punish bad actors incase of attack on your node (publishing false state to chain) by publishing new state and penalizing
- taro for colored coins/assets
bip 351 payment codes for private transactions
fedimint - protocol for multisig group m:n (federation) that issues 'ecash' that is backed by sats. Tradable with other federation members (half-online). No/lower fees are not written to chain unless ecash is turned into sats by federation.

btcpayserver

crypto payment server that supports invoices (multiple payments, refunds, tolerances etc)
xmr config requires the view only wallet.keys, wallet and password file be available before sync can complete
sync MUST be completed before the FIRST store can be created
