A common point of confusion for beginners is the difference between a and a Public Key . In legacy Bitcoin protocol architecture, they are not the same thing. The P2PKH Protocol
To understand the search for the 1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf public key , one must understand how Bitcoin’s asymmetric cryptography operates.
The string 1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf is a , not a public key itself (though it is derived from one). It is famously known for being the address that received over 185,000 BTC (worth billions today) from the infamous 2016 Bitfinex hack . 1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf public key
: Since that initial deposit in 2011, not a single satoshi has ever been moved out of the address.
To understand the enigma of this address, we must look under the hood of Bitcoin's cryptographic engine. The address 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF is what is known as a . This "Legacy" address format is the original Bitcoin address type. It's an alphanumeric string derived from a more complex piece of data: a public key . A common point of confusion for beginners is
: To move or sign a transaction out of this address, an entity must hold the corresponding 256-bit private key. This key is mathematically paired to the public key through the Elliptic Curve Digital Signature Algorithm (ECDSA).
: It is important to distinguish between the Bitcoin Address (the "1Feex..." string) and the Public Key . While the address is public, the raw public key is technically only fully revealed on the blockchain once a transaction is sent from that address. Since this address hasn't spent any funds, its full public key remains unhashed only in the owner's private wallet. Market Significance The string 1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf is a , not a
Therefore, unlike addresses that have been spent from (where you can look up the public key on a block explorer), 1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf has no visible public key.
The funds sitting on the 1Feex public key did not arrive through normal trading. On March 1, 2011, a massive security vulnerability compromised the hot wallet of Mt. Gox, which was then the largest cryptocurrency exchange on Earth.
Wright claimed through his company, Tulip Trading, that he owned this address and that his private keys were deleted in a hack. The Rebuttal:
