## II. Payment Processors
A payment processor is a company or software that helps businesses accept payments from their customers. A payment processor is like a middleman, handling the technical details of the transaction, such as verifying the payment information, making sure the funds are available, and transferring the money to the business.
They typically charge fees for their services, which can be a flat rate per transaction or a percentage of the total amount. They also often offer additional services like fraud detection, chargeback protection, and payment analytics.

## III. BitPay
- A payment processor that enables businesses to accept Bitcoin
- When a customer pays with Bitcoin, BitPay converts the payment into the merchant's preferred fiat currency, such as US dollars, and settles the payment to the merchant's bank account.
- 3rd party centralized company that requires merchants to rely on its services, which can create a single point of failure and potentially compromise the security and privacy of users
- vocal supporter of increasing the block size (see [BIP 101](https://github.com/bitcoin/bips/blob/master/bip-0101.mediawiki))
## IV. The Tweet
- [Nicolas Dorier 2017](https://twitter.com/NicolasDorier/status/898378514256207872?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E898378514256207872%7Ctwgr%5E902ae0d2ab7c046ef0a1d42db4cb628c6d57b8b0%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fbitcoinundco.com%2Fen%2Fnicolas-dorier%2F) ([Bitcoin Core Contributor](https://github.com/bitcoin/bitcoin/graphs/contributors), Official BTCPay Server emperor)
- Response to [a BitPay tweet](https://bitpay.com/blog/bitcore-segwit-activation/) (a 3rd party bitcoin payment processing Co.) made which said that:
"Nodes which fail to upgrade to support Segwit will face major security risks, including the risk of double-spend transaction fraud"
- Segregated Witness (SegWit) was activated as a soft fork in the Bitcoin network in August 2017. This means that it was implemented in a way that is backward compatible with the previous version of the Bitcoin software, so nodes that have not upgraded to the new version can still validate transactions that use SegWit.
- Dorier felt that BitPay's support for BIP-101 represented a disloyalty of the Bitcoin community's values of decentralization and peer-to-peer consensus, and he publicly criticized BitPay for its stance.
- He had onboarded several people to BitPay and said in [The Anita Posch Show podcast](https://podcasts.apple.com/us/podcast/nicolas-dorier-be-your-own-bank-with-btcpay/id1432576313?i=1000501940281) that he felt betrayed
- So he started working BTCPay Server - open-source self-hosted payment processor that allows merchants to accept Bitcoin without relying on a third-party service.
