In order to create multisig address you need public keys. https://bitcointools.site/tool/address-to-pubkey Only used addresses have public keys revealed (see my previous post). ... Here are 4 IMO honest lists with public keys revealed:
1) BTC max 15-of-15. Pros: - BTC is the world's number one. Cons: - Group of 3-5 smart cheaters can play 15 honest people. - In order to participate in multisig you need to publish your public key. Due to BTC design, public key becomes really public only after first sending transaction. Or you can explicitly publish it in plain text. Right now it is safe, but in the next 10 years it will be unsafe because quantum computers will be able to restore private key from public key. Untouched BTC addresses will remain safe, but public keys - no. (however, developers have enough time to invent protection)
2) NEM max 64-of-64. Pros: - It is practically impossible to write so many fake lists, someone will certainly identify cheating. - Built-in messaging support, and public and private. Cons: - NEM is little-known and is slowly getting down - https://coinmarketcap.com/ - number 72
If you create NEM wallet and append address in your text, it doesn't create any vulnerability. It's just additional technical possibility. You can use it or not to use.
Multi-signature address is like a safe box with several locks. Key holders can open it only together. For example "5-of-7 multisig bitcoin address" means that there are 7 keys, and any 5 of them are needed for sending bitcoins.
BTC allows only up to 15-of-15, but other cryptocurrencies allows much more keys (for example https://nem.io has unlimited M-of-N)
The idea is simple - groups of people with similar targets can top up multisig addresses in order to prove their intention to pay.
Your list may be very smart and honest but it is just a declaration. But sending real money to separate address looks much stronger. Potential agents will see not just words, but real money already prepared for them.
And by the way, it can rise motivation for donors significantly. There are a lot of cheaters here, but cheating with multisig address is practically impossible (or at least is much harder).

In short:
1000 perfect lists with 100 BTC total amount = 1 "unit of trust"...
Prediction markets can be considered as some sort of alternatives. This is absolutely different technology, but with similar results - motivating anonymous people to do something special. Here are 3 projects which in theory may permit betting on delicate subjects: 1) https://github.com/AugurProject/augur-app - installable application 2) https://fairlay.com/ - web site 3) https://omen.eth.link/#/liquidity - web site (but you need to disable ad-blocker)
Features (or bugs): adaly.io removes all non-latin characters and even "/" and "+" characters - that's why base64url is needed. Minimum amount is 1 ada (approx 3 usd).
thacypha Objectively - BSV was(is) under attack Objectively - Memo is not open source Subjectively - I had problems with Memo in Tor Browser
And BTW, if CryptoFights allows publishing long text then it can be one more alternative
--- 1CJaRL5dFC3gnvmU I will monitor hashtag #hmwyda but on member.cash - https://member.cash/#topic?topicname=hmwyda It is actually the same thing as memo.cash, but truly open source, and allows to post long text (but formatting is horrible)
1) memo.sv Frontend looks good, but backend works unclear.
2) BSV directly via filepay script Works clear, but BSV itself is not very stable.
3) member.cash BCH is active and stable, but member.cash is not very convenient.
4) myetherwallet ETC Easy and cheap, but ETC is scandalous project and it's future is unclear.
5) Cardano metadata I know nothing about Cardano, but at least it is number 4 in the most valuable currencies - https://coinmarketcap.com/ - worth to try.
6) myetherwallet ETH Expensive, but more reliable than all above.
And 547 satoshi minimum amount is only for BTC/BCH/BSV, but ETH/ETC allows to send zero amount (I suppose). Try to send 0 ETC to 0x547FaCE777777777777777777777777777777777 - I think it should work.
Frankly, I didn't think much about how to organize posts, I reported just easy technical method.
It can be some "magick" address, or special googlable words (e.g. "hmwyda_eth_russia"), or you can try to find ETH text search engines (e.g. https://ethereum.ms but it doesn't work very well).
I found two possible alternatives: https://member.cash is BCH-based, but it allows to post long text, it splits text into several transactions. https://www.myetherwallet.com is well known ETH wallet. It works in browser and allows to set arbitrary "data" field while sending transactions. You can try them out and share your experience here.
BSV is facing a difficult situation. From june 20 to july 10 several successful attacks occured - https://duckduckgo.com/?q=BSV+block+withholding+attack And beyond that, one mining pool has captured almost entire hashrate - https://duckduckgo.com/?q=BSV+TAAL+hashrate I hope they will address this, but anyway, it's a good idea to find some alternatives to BSV and memo.sv You can write suggestions here. Where else it would be possible to publish lists.
