Unnamed Noncustodial Inchoate Sidechains On Bitvm (Unisob)

I have an independent bitvm sidechain model that works without a federation. Instead, there is a "bridge operator" who assists with depositing money to the sidechain as well as with the "happy path" of withdrawing from the sidechain. In my version, you can withdraw even if the bridge operator ceases operations, because there is also a "sad path" that does not require his ongoing cooperation

the main idea is that when you want to deposit money onto the sidechain you should get a "withdrawal contract" from the bridge operator

the withdrawal contract is done in bitvm and it basically says, if you (the withdrawer) can provide a proof of a valid withdrawal request from the sidechain, the prover has up to X blocks to supply proof that he sent you your money on bitcoin

if he does not supply that proof, you may slash him and take the funds that way

Surfchains

The Sponsor locks up a certain amount of liquidity for a certain number of blocks, like for example 10'000, which is roughly 3 months. For locking up his liquidity and allowing people to use it on the sidechain he is rewarded with interest, for example 1%. The Sponsor is also the primary market maker, his function is to provide a stable peg, thus make the sidechain desireable for people to use. The Sponsor has no way to claw back the coins he locked up, they are predetermined to go to the mainchain miners can only regain custody of his 10% escrow if the covenant chain is played out block by block all the way to the end.

Example schedule

duration:		10'000 blocks
bitcoin locked up:	100%

I was drawn to programming, science, technology and science fiction
ever since I was a little kid. I can't say it's because I wanted to
make the world a better place. Not really. I was simply drawn to it
because I was drawn to it. Writing programs was fun. Figuring out how
nature works was fascinating. Science fiction felt like a grand
adventure.

Then I started a software company and poured every ounce of energy
into it. It failed. That hurt, but that part is ok. I made a lot of
mistakes and learned from them. This experience made me much, much

How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,
